ABSTRACT We provide a characterization of the floral scent chemistry of nine species of Philodendron present in French Guiana. The scent samples were obtained by dynamic headspace, in situ in French Guiana, or from plants in the living aroid collection at the Botanical Garden of the University of Brasilia. Overall, we identified 43 volatile organic compounds (VOCs) belonging to the compound classes of monoterpenes, sesquiterpenes, irregular terpenes, benzenoids, aliphatics, jasmone derivatives, and nitrogen-containing compounds. Five of these floral VOCs are new reports for Philodendron. Interestingly, the floral blends in the investigated species were comprised of 3–22 VOCs; but when considering only major VOCs (≥5%), each fragrant blend could be summarized into one up to four constituents. Except for P. acutatum and P. billietiae, whose floral scents were largely dominated (≥93%) by 4-vinylanisole, fragrances of the investigated species were dominated (≥62%) each by a different VOC (i.e. dehydrojasmone, dihydro-β-ionone, (E)-4,8-dimethylnona-1,3,7-trien-5-yl acetate, methyl benzoate, 1,3,5-trimethoxybenzene, dihydrobovolide, or (Z)-jasmone). Consequently, all floral scent compositions significantly differed from one other. We compare our results to published data to provide an insight into the floral scent chemistry within the genus Philodendron. We further discuss the diversity of VOCs in cyclocephaline scarab-pollinated aroids.

ABSTRACT Taraxacum hybernum Steven (Asteraceae family) native to Southeast Europe is a promising rubber-bearing dandelion species. In the 1930s, several phenotypically distinct forms were described in this dandelion, such as brown-achened and pinkish-achened. More than 70 years after termination of research of temperate zone rubber-bearing plants we were able to find both forms of this species of dandelion in natural habitat. The species is still poorly studied, and there is no information about the differences in the quality and quantity of rubber between brown-achened and pinkish-achened forms. Therefore, the purpose of our study was to analyze the root morphology and yield, the rubber and inulin content, and to determine the molar mass of rubber in brown-achened and pinkish-achened T. hybernum. These two forms of T. hybernum, as well as T. kok-saghyz Rodin and T. brevicorniculatum Korol., were studied. The results show that the root shape most attractive for domestication is typical of brown-achened T. hybernum. The greatest mass of roots was gained for pinkish-achened T. hybernum. The rubber content was about 6% in T. kok-saghyz, 3% in both forms of T. hybernum, and 1.5% in T. brevicorniculatum per dry root mass. Taraxacum kok-saghyz and pinkish-achened T. hybernum turned out to be the leaders in inulin content. Of all four dandelions, the molar mass of rubber was more than 1 million g/mol only for T. kok-saghyz and pinkish-achened T. hybernum. Pinkish-achened T. hybernum is a good alternative for T. kok-saghyz and can be recommended for domestication and cultivation in the temperate zone.

ABSTRACT A sterile hybrid between diploids Isoetes gymnocarpa and I. longissima (s.s.) (Isoetaceae) is described from Anguillara, Trapani Province, Sicily, Italy. Although closest in morphology to I. gymnocarpa with which it was growing, the small group of hybrid plants also exhibited features of I. longissima which occurred abundantly within 50 m of the site. In addition to such classic hybrid characteristics as larger plant size (hybrid vigour) and polymorphic, aborted megaspores with ornamentation intermediate between that of the putative parents, the microspores of the hybrid exhibit both the arachnoid ornamentation features of I. gymnocarpa and the echinate features of I. longissima (s.s.). Isoetes ×angeloi, hyb. nov., is the first non-aquatic Isoetes hybrid to be formally described. It is also the first hybrid quillwort to be confirmed from the Mediterranean Basin.

ABSTRACT Typha domingensis Pers. (cattail) is a globally widespread aquatic plant that causes significant impacts as an invasive species; this ability is dependent on its photosynthetic capacity that is related to leaves. Thus, understanding leaf development is essential for interpreting shoot growth and the formation of its photosynthetic area. This study investigates leaf ontogeny in T. domingensis from early stages until complete development of primary tissues. Plants were collected from natural wetlands and cultivated in a greenhouse. Rhizomes were then selected, and leaves were removed to enable the emergence of new shoots. Rhizome fragments containing leaves were collected at 1-day intervals until day 7 and were subjected to routine procedures in plant microtechnique. New leaves emerged from lateral buds located along the rhizome. The anatomy of scale leaves differs from that of photosynthetic leaves since they contain solid inclusions without palisade parenchyma. Leaf primordia arose laterally from the shoot apical meristem, which was organized as a tunica-corpus. Final leaf shape was influenced by different meristematic zones: the leaf apical meristem, the marginal meristem, the rib meristem, and intercalary meristems. Most leaf tissues developed basipetally, except for xylem and phloem. Within seven days following leaf initiation, all primary tissues were developed and morphologically functional. Leaf formation of Typha domingensis is similar to that of other monocot species. Leaves of T. domingensis develop very early, providing fully functional photosynthetic tissues, which may have implications for its invasive capacity.

ABSTRACT An orange-flowered natural putative hybrid of Begonia boliviensis × B. micranthera was recently discovered from Calilegua National Park in Jujuy Province, Argentina. Propionic hematoxilyn method was applied to study its chromosomal behavior during meiosis, Müntzing’s stain solution was used to determine pollen grain fertility and ITS2 and rbcL sequences were amplified to help confirm the parentage of the putative hybrid. This plant has a gametophytic chromosome number of n = 13, very regular meiotic behavior and an intermediate percentage of viable pollen compared to other studied natural putative hybrids. The ITS2 sequence data support the parentage of the putative hybrid begonia but sequence comparison shows its ITS2 sequence is more similar to B. micranthera than to B. boliviensis. The molecular marker rbcLa revealed that there are no differences between the sequences for B. boliviensis, B. micranthera and the putative hybrid. Begonia boliviensis × B. micranthera is a diploid plant that, due to its moderately high pollen fertility (43.3%) compared to other natural Begonia hybrids (which are often sterile) and regular meiosis, would likely be able to self-cross or cross with other begonia taxa.

ABSTRACT Alexander von Humboldt and Aimé Bonpland departed from Europe on a journey to the American continent. The naturalists explored America’s biodiversity, collecting approximately 6,000 plant species between 1799 and 1804 and registering the customs and habits of local people. To date, the medicinal and useful plants reported by Humboldt and Bonpland during their American journey have not been studied in depth. The aim of the present report is to present data recorded by both naturalists in their books Voyage de Humboldt et Bonpland. Sixième Partie, Botanique. Plantes Équinoxiales (Volumes I and II), published from 1805 to 1817 in 17 parts, regarding medicinal and useful plants collected by them. Data on plants were obtained from the two-volume work, which was deposited and accessed in the library of the Biological Sciences Sector of Universidade Federal do Paraná, Curitiba, Brazil. Traditional information about the plants was translated and tabulated. The botanical identification of each plant was updated according to current nomenclature. Correlated pharmacological studies were obtained from scientific databases. A total of 130 plant species from 49 different botanical families are described in the Humboldt’s and Bonpland’s Plantes Équinoxiales books. Fourteen species were reported for medical purposes (snake anti-venom agents, treatment of cutaneous and digestive diseases, and astringent agents), while 65 species were described for some other use (ornamental, construction, furniture and objects, edible plants, dyeing, mining etc.). The data recorded by these naturalists represent a rich unexplored source of information regarding the American flora and its traditional uses.

ABSTRACT The leaf morphology of Selaginella species from subtropical South America show differences in structure and ultrastructure that are useful for species identification. We studied the following epidermal traits: micromorphology of stomatal types, distribution patterns of silica cells, silica cells and silica bodies of Selaginella convoluta, S. microphylla, S. sellowii and S. sulcata, using light and scanning electron microscopy. Five stomatal types were observed, anomocytic, actinocytic, anisocytic, staurocytic and tetracytic and two additional variants, anomodiacytic and anomoparacytic. Five silica cell distribution patterns were identified, laminar, medial, medial-basiscopic, subcostal, and submarginal. Pyramidal silica bodies and conical bodies with concave base are described for the first time. In the studied species, silica bodies are pyramidal in S. convoluta and globular, conical and pyramidal in S. microphylla, whereas in S. sellowii and S. sulcata they are conical, with concave base of different sizes. Illustrations of the epidermal features, LM photographs, SEM micrographs and comparative tables are presented.

ABSTRACT With the objective to develop a scent database that could be used for perfume and cosmetics applications, a comparative analysis of the floral profiles close to one hundred odorous flowering plants found in Reunion Island has been undertaken for the last few years in our laboratory. A part of this work relating to three Hedychium species (the well-known H. coronarium but also H. flavescens and H. gardnerianum) is presented here. To achieve this, the solid-phase microextraction (SPME) on living flowers coupled to GC/MS was used. A total of 53 volatiles were identified belonging to aliphatic ketones, monoterpenes (hydrocarbons and oxygenated), sesquiterpenes (hydrocarbons and oxygenated), phenylpropanoids/benzenoids and miscellaneous. The phenylpropanoid/benzenoid and terpenoid classes were the main volatile classes. (E)-β-ocimene, linalool, (E,E)-α-farnesene, (E)-nerolidol, methyl benzoate, methyl salicylate, (E)-isoeugenol and indole were the major compounds detected. Results also revealed significant aroma variation among the different flowers.

ABSTRACT A new species of liverwort, Ricciopsis asturicus sp. nov., is described from dinosaur-bearing Kimmeridgian (Upper Jurassic) deposits of the Lastres Formation in Asturias (NW Spain, Iberian Peninsula) based on a new combination of taxonomic characters, including differences in thallus shape, branching, segment surface, size, and shape. This new species represents the oldest evidence of bryophyte from the Mesozoic of the Iberian Peninsula so far, and it also represents the first evidence of the genus Ricciopsis in this area. In addition to the description of the Ricciaceae remains, palynological analyses were carried out in order to understand the paleoenvironmental context. The remains of Ricciopsis asturicus sp. nov. were found in life position on grey marly siltstones forming dense mats, suggesting that some areas of the Lastres Formation presented shallow freshwater pools placed in channel abandonment areas into an upper deltaic plain, where these mats of liverworts could proliferate during the apparent semiarid climatic conditions occurring during the deposit of the Lastres Formation. This interpretation is supported by the palynological study, which reveals the presence of ferns and Cheirolepidaceae plants (Leptolepidites sp., Klukisporites sp., and tetrads of Classopollis sp.) in nearby areas.

ABSTRACT Bulk macerations of a mesoflora from the late Permian Zechsteinmergel of Gera-Trebnitz, east Thuringia, yielded – apart from a number of typical Zechstein taxa – two conifers previously unrecorded from the German Zechstein Basin. These two conifer genera, Ortiseia Florin 1964 and Majonica Clement-Westerhof 1987, were so far only known from northern Italy. The type species of Culmitzschia Ullrich 1964 (C. florinii Ullrich 1964), a broad-leaved conifer from the southern margin of the Zechstein Basin, appears to be a synonym of Ortiseia leonardii Florin 1964, the type species of Ortiseia Florin 1964, the latter name having priority. All bona fide species attributed to Culmitzschia after 1964 differ from Culmitzschia as defined by Ullrich (=Ortiseia) and are transferred to Ullrichia gen. nov., resulting in the new combinations U. intermedia (Florin 1939) Kerp comb. nov., U. laxifolia (Florin 1939) Kerp comb. nov. and U. mucronata (Florin 1939) Kerp comb. nov.
