ABSTRACT Native Rubus were brought from North America to European botanical gardens in the 18th and early 19th centuries, and some were described as new species. Limited knowledge of Rubus in that era, typically combined with brief descriptions, led to many incorrect interpretations, causing much confusion (especially in North America). We established a project to clarify the identity of these confusing species by reviewing types and descriptions along with comparative work involving modern collections. We identified seven putative North American Rubus species named from early European garden collections: R. villosus Aiton, R. vulpinus Poir., R. pensilvanicus Poir., R. flagellaris Willd., R. inermis Willd., R. heterophyllus Willd., and R. argutus Link, and four other names in the early European botanical literature of possible North American origin: R. decumbens Thunb., R. inermis Thunb., R. enslenii Tratt., and R. floridus Tratt. We affirmed the current applications of R. flagellaris, R. argutus, and R. enslenii. Rubus villosus is identical with R. leviculus L.H. Bailey, while the taxon to which R. villosus was generally applied in the 19th century, R. allegheniensis Porter, appears to be identical with R. vulpinus. Rubus heterophyllus Willd. was identified as an earlier name for R. plicatifolius Blanch. Rubus inermis Willd. is identical with R. ulmifolius Schott and must have originated in the Old World. Thunberg's other American Rubus, R. decumbens, can be identified as R. arundelanus Blanch. Rubus floridus remains a puzzle. If its type represents a sample of a determinate flowering branch from a large, mounding dewberry, it is closest to R. grimesii L.H. Bailey, but it could also have been taken from a side-branch from an unknown upright blackberry. Another name for which identity could not be definitively established is R. pensilvanicus. It is allied with R. allegheniensis, but its type is insufficient to determine if it is an extreme form of that species, a related taxon, or a hybrid of it with a species of section Arguti (Rydb.) L.H. Bailey. We propose the name, R. revealii sp. nov. for the corymbose to weakly racemose Arguti previously considered as R. pensilvanicus sensu L.H. Bailey. Herein, we lectotypify R. abactus L.H. Bailey, R. arundelanus, R. decumbens, R. grimesii, R. inermis Thunb., R. invisus (L.H. Bailey) Britton, and R. vulpinus, and designate neotypes for R. argutus and R. heterophyllus.

ABSTRACT A new species of Capparis L., C. irenae Fici, sp. nov., is described and illustrated from Tigapuluh Mts., Riau Province of Sumatra, where it is known from a single locality in forest communities. The new species, belonging to Capparis sect. Monostichocalyx Radlk., is related to C. diffusa Ridl., differing in several characters as the glabrous twigs, longer petioles and leaves, flowers arranged in racemes with cataphylls at the base, longer petals hairy outside and longer filaments. Its affinities with other related taxa and its conservation status are discussed. Moreover a distribution map of the new species and an identification key to the species of Capparis recognized in Sumatra are provided.

ABSTRACT A new species, Garcinia urceolata Munzinger, Bruy & M. Pignal, sp. nov. (Clusiaceae), is described from New Caledonia. It is restricted to North Province, from the Tchamba valley in the south to Mandjélia in the north of the main island of Grande-Terre, occurring in dense humid rainforests on non-ultramafic substrate. Material of this small tree species was first collected more than fifty years ago but was confused with G. virgata Vieill. ex Guillaumin as both taxa have small leaves. Garcinia urceolata, sp. nov. differs from G. virgata in a number of features of the leaves, flowers and fruits. Garcinia urceolata, sp. nov. also grows at higher elevation and in wetter conditions than G. virgata. Both species are purported to have dehiscent fruit, along with other New Caledonian members of the genus, a distinctive character that was used to justify the description of the genus Septogarcinia Kosterm., which is no longer regarded as distinct from Garcinia L. Line drawings and colour photos are provided for both the new species and for G. virgata for comparison, along with a preliminary risk of extinction assessment for each of them, which indicates that G. urceolata, sp. nov. is Vulnerable (VU) while G. virgata is Near Threatened (NT).

RÉSUMÉ Deux nouvelles espèces de Thiollierea Montrouz. (Rubiaceae, Chiococceae) endémiques de Nouvelle-Calédonie sont décrites et illustrées. Elles appartiennent toutes deux au groupe des espèces à grandes fleurs rouges et/ou jaunes. Chacune est micro-endémique d'un ou deux massifs ultramafiques de la côte Nord-Ouest de la Grande Terre. Thiollierea papineaui Barrabé & Fleurot, sp. nov. ressemble à T. lenormandii (N.Hallé & Jérémie) Barrabé & Mouly mais en diffère par ses inflorescences uniflores plus compactes soutenues par un pédoncule plus court, ainsi que par ses lobes du calice plus longs. Thiollierea naounarum Fleurot & Barrabé, sp. nov. est proche morphologiquement de T. macrophylla (Brongn.) Baum-Bod., mais se distingue par ses inflorescences généralement uniflores, ses bractées foliacées élargies, ses corolles à symétrie zygomorphe, et la présence de verrues sur ses hypanthes. En outre T. papineaui, sp. nov. est présente sur le massif de Tiébaghi et à la base du Kaala, dans la région de Karembé. Thiollierea naounarum Fleurot & Barrabé, sp. nov. a été observée à la base du massif de Kopéto.

ABSTRACT Anarrhinum fruticosum Desf. (Antirrhineae, Plantaginaceae) is a very variable species. Three subspecies are currently recognized: A. fruticosum subsp. fruticosum, A. fruticosum subsp. brevifolium (Cosson & Kralik) D.A. Sutton (synonym of A. brevifolium Cosson & Kralik), and A. fruticosum subsp. demnatense (Cosson) Maire (synonym of A. demnatense Cosson). Anarrhinum brevifolium was recently typified by Domina & El Mokni (2019), while these other two names are discussed and lectotypified in the present paper. Lectotypes are designated from an illustration published by Desfontaines (A. fruticosum), and a specimen from P-Cosson herbarium (A. demnatense).

ABSTRACT The anatomical and morphological structure of the seeds and vegetative organs of the endemic caudiciform plant of South Africa Petopentia natalensis (Schltr.) Bullock (Apocynaceae) has been investigated at different stages of ontogenesis: seedlings, juvenile and immature plants. It has been noticed that endosperm of P. natalensis seeds is developed similar to endosperm of seeds of mesophytic representatives of the Apocynaceae family. Seedling hypocotyl is also of mesophytic type in contrast to those of such succulents as Adenium obesum (Forssk.) Roem. & Schult. and Pachypodium lamerei Drake. In juvenile plants of P. natalensis the hypocotylous zone is constantly increasing to form an enlarged basal part of the stem. Conducting tissues have a different pattern of development in the hypocotyl and epicotyl. In the basal part of the stem they are represented by collateral vascular bundles scattered among the parenchymal cells, while in the climbing part of the stem, the conducting system is represented by a complete ring. Unlike other immature caudiform plants, P. natalensis has the bundle type of conducting system. As a rule, the basal expanded part of the P. natalensis stem is formed exclusively from the hypocotyl and it occurs mostly due to generation of abundant number of cortical and pith parenchymal cells.

ABSTRACT Since its first valid description by Linnaeus in 1753, the genus Delphinium L. has undergone numerous taxonomical changes that we synthesize here. The knowledge of the taxonomic history of the genus is essential to clarify its circumscription. For this purpose, we outline its pre-Linnaean taxonomic history, from Dioscorides' translated works dating back to the 16th century to Tournefort's classification in 1694. Regarding its post-Linnaean history, we discuss the three different lectotypifications proposed during in the 20th century. In addition, we amend the description of the typical flower of Delphinium by including the characteristics of the species D. ecalcaratum S.Y. Wang & K.F. Zhou and D. turcicum (H.Duman, Vural, Aytaç & Adigüzel) Espinosa with actinomorphic flowers.

ABSTRACT Hyptidendron Harley, one of the 19 genera recognized for the subtribe Hyptidinae, has some of its species with a narrow campos rupestres (a Brazilian vegetational formation) distribution, often restricted to a single mountain range. We report a new species, Hyptidendron pulcherrimum Antar & Harley, sp. nov., endemic to a single mountain in the Serra do Padre Ângelo, a disjunct area of campos rupestres from where some new angiosperm species have been recently described. The new species is unique due to the morphological combination of flowers arranged in dichasial cymes, indumentum composed of curved, rigid, broad-based hairs, leaves petiolate, glabrescent and bullate, corolla tomentose, with the tube curved, 7.5-10 mm long and one slightly winged nutlet per fruiting calyx. The new species is compared with Hyptidendron vauthieri (Briq.) Harley the most similar species morphologically. We also provide a complete description, diagnosis, illustration, distribution map with the new species and closely related species, a photograph plate, and a preliminary conservation status assessment.
摘要:哈利水蛭属(Hyptidendron Harley)是水蛭亚科(Hyptidinae) 19属之一，其部分种具有狭窄的campos rupestres(巴西的一种植被构造)分布，通常局限于单一山脉。我们报告了一个新种，Hyptidendron pulcherrimum Antar & Harley, sp. nov.，特有种在Serra do Padre Ângelo的一座山上，一个campos rupestres的分隔区，最近描述了一些新的被子植物物种。该新种的独特之处在于其形态组合:花排列在二重聚伞花序中，毛被由弯曲的刚硬的宽基毛组成，叶具叶柄，后脱落，具苞片，花冠被绒毛，筒部弯曲，长7.5-10毫米，每果萼有一个微翅小核。并将新种与水蚤(Hyptidendron vauthieri, Briq.)进行了比较。哈利是形态上最相似的物种。我们还提供了完整的描述、诊断、插图、新种和近缘种分布图、照片和初步的保护状况评估。

Après 170 ans d’exploration botanique, on commence à mieux comprendre la flore gabonaise, dont 75% des probables 7000 espèces d’angiospermes seraient actuellement décrites. Il était donc intéressant de publier un premier bilan, proposant une synthèse sur les formations naturelles, une description de nombreuses espèces représentatives (1680), dont des invasives (56), enfin de tracer des perspectives sur l’avenir des études floristiques africaines. Les Auteurs nous offrent ainsi un volume riche en informations (1/3 des espèces connues est traité) et élégant dans sa présentation. En quelques pages (11-24) la géographie physique et les formations végétales du pays sont brossées avec brio et l’appui d’une belle iconographie. Suivent deux courts chapitres assez originaux, l’un donnant une phylogénie actualisée des angiospermes (p. 25-27) et justifiant l’utilisation conjointe des classifications APG III et APG IV, l’autre – rédigé par Marc Sosef – retraçant les progrès des connaissances botaniques gabonaises (p. 28-31). Cette analyse historique expose bien les difficultés techniques rencontrées, notamment dans les stratégies de collecte et de publication des résultats. Les obstacles propres à la floristique africaine n’ont pu être surmontés que tout récemment, par la mise en œuvre de moyens plus importants, par des équipes élargies et impliquées dans des programmes d’expédition continus et coordonnés. Le corps de l’ouvrage (p. 35-769) décrit un tiers des espèces connues, toutes accompagnées de photographies de terrain. Les synonymies et bibliographies essentielles sont rappelées, les caractères diagnostiques sont détaillés en 10-15 lignes. Les données écologiques, phytogéographiques et ethnobotaniques sont rédigées de manière concise. L’enthousiasme des Auteurs – tous botanistes de terrain – rayonne à toutes les pages. En conclusion l’ensemble de ce travail considérable est un régal de consultation et constitue un soutien documentaire majeur aux recherches actuelles en botanique et écologie afrotropicales. Il mérite à l’évidence une large diffusion.
