RÉSUMÉ La section Melanocrommyum Webb & Berthel. du genre Allium L., de barycentre irano-anatolien, a longtemps été considérée sous une seule espèce en Europe de l'ouest et au Maghreb, à savoir la messicole archéophyte Allium nigrum L.. La découverte d'Allium cyrilli Ten. en Algérie vient confirmer la coexistence des deux espèces au Maghreb, comme cela a été récemment mis en évidence en France et en Espagne. Nous donnons une comparaison détaillée et illustrée des deux espèces à partir de récoltes et de photos effectuées in situ en Algérie. A travers une révision des parts historiques des herbiers P et MPU, nous avons pu écarter l'hypothèse d'une éventuelle présence ancienne d'A. cyrilli sous une appellation erronée. L'espèce semble donc d'apparition relativement récente dans les cultures d'altitude en Algérie. Par ailleurs une régression d'A. nigrum dans les cultures de plaine paraît probable. Nous proposons enfin un complément de clé d'identification basé sur le modèle de la flore d'Algérie de Quézel & Santa.

ABSTRACT A new species of Onosma L. (Boraginaceae: Lithospermeae), from the Hakkari province of eastern Turkey, is described and illustrated. The new species is endemic and distributed in a narrow area in the Sat Mountains. Taxonomically the closest relative of Onosma satensis sp. nov. is O. polioxantha Rech. f. which also occurs in Turkey. In addition, it is primarily distinguished from O. polioxantha by its navicular leaves, longer and reticulate cauline leaves, longer pedicels and calyx, longer and densely patent short setulose outside, reticulate corolla and bigger nutlets. The geographical distributions and map, detailed photographs, habitat description, vernacular name, an IUCN conservation status and identification key for O. satensis sp. nov. and O. polioxantha were also provided. Nutlets and pollen micrographs of O. satensis sp. nov. are presented using scanning electron microscopy.

ABSTRACT Hitherto characters derived mostly from macromorphology were used to distinguish among the members of Acanthopsis Harv., a taxonomically difficult group of plants endemic to arid parts of southern Africa. The taxonomic significance of leaf and bract indumentum in Acanthopsis was investigated using light, and scanning electron microscopy. Five non-glandular and three glandular trichome types were distinguished on the leaves and floral bracts. None of these trichome types are unique to the genus. Although the indumentum is variable in Acanthopsis, the density/dominance of specific trichome types was useful to distinguish among certain taxa, particularly on the abaxial surfaces of leaves and bracts. Each species of Acanthopsis has a characteristic trichome complement as far as dominant trichome types on both leaves and bracts are concerned. However, no obvious association between the type of trichomes and habitat (degree of aridity) or geographical distribution was evident.

ABSTRACT Two endemic species of Cryptocarya R.Br. are described from New Caledonia. Cryptocarya conduplicata Munzinger & McPherson, sp. nov. was previously confused with C. aristata Kosterm., which it resembles in its typically numerous lenticels and oblate fruit, but from which it differs most noticeably in its leaf blades partly folded longitudinally (vs blades flat), and its smaller fruits (13-15 mm long vs 20-30 mm long). Cryptocarya ovoidea Munzinger & McPherson, sp. nov. can be distinguished most easily from C. pluricostata, its sister species according to molecular data, by its indument (hairs sparse, whitish, cream-grey to blackish, quickly falling vs. hairs dense, ferrugineous sublanate and subpersistent in C. pluricostata). As well, the fruit of C. ovoidea, sp. nov. is ovoid and its perianth is caducous, in contrast to the fruit of C. pluricostata, which is ellipsoid and retains its perianth. The two new species are trees occurring in dense humid forest, and are restricted to non-ultramafic substrate. Cryptocarya conduplicata sp. nov. is common, known from three protected areas, and is assigned a preliminarily Least Concern IUCN status, while C. ovoidea sp. nov. is only known from two individuals on Mont Aoupinié, a protected area, where many inventory plots were established without finding any individuals; thus, we assign it a preliminary status of Critically Endangered (CR).

ABSTRACT The endemic New Caledonian Solmsia Baill. (Thymelaeaceae Juss.: Octolepidoideae Gilg) was founded in 1871 on two species, S. calophylla Baill. and S. chrysophylla Baill. Over the past 150 years, the genus has received little attention taxonomically or otherwise. New morphological, ecological and distribution information gathered from 484 herbarium specimens indicate that the two currently recognized species (evaluated as morphogroups) exhibit continuous, overlapping variation based on statistical multivariate analyses. Both partially sympatric morphogroups are treated here as conspecific under S. calophylla, the lectotype of the genus, and formal recognition of either group at any infraspecific rank is deemed unnecessary. The recircumscribed, single species is completely restricted to Grande Terre, where it occurs in maquis vegetation on ultramafic rocks (peridotite and serpentinite) and some form of ferrallitic soil (ferralsols/oxisols). Lectotypes, selected from a total of c. 55 sheets representing probable or possible syntypes, are designated for both of Baillon's binomials. Full descriptions are provided for the genus and species, accompanied by illustrations, photographs, a distribution map, and a preliminary IUCN conservation assessment of Near Threatened (NT). Morphological and biogeographical relationships of Solmsia are discussed in the phylogenetic context of other Octolepidoideae, a basal subfamily of Thymelaeaceae, along with the closely related, but massively disjunct, Guayana Shield-centered Tepuianthus Maguire & Steyerm. (formerly Tepuianthaceae Maguire & Steyerm.). Dehiscence and capsule size at maturity are also confirmed and documented, respectively, for the first time in the closely related, Deltaria Steenis, another poorly known New Caledonian monospecific endemic genus.

ABSTRACT The Eurasian species Artemisia vulgaris L. has been reported from the Eastern Cape Province (Stutterheim District) in South Africa since at least half a century. However, examination of relevant herbarium specimens has demonstrated that the South African plant material belongs to a morphologically similar East Asian species, A. verlotiorum. It is included in the South African Alien and Invasive Species Lists as a prohibited species absent in the country. However, judging from available data, in South Africa it has become a locally naturalised weed of cultivated land and apparently is difficult to eradicate. A. verlotiorum indeed is a pernicious weed in many regions of the world, appearing to be much more invasive than A. vulgaris, especially in warm-temperate and subtropical climates. Characteristics useful for distinguishing these two species are provided.

ABSTRACT The genus Vepris Comm. ex A.Juss. (Rutaceae) includes around 85 species occurring mostly in Africa and Madagascar, among which three West and Central African species, differing from others in the area by their simple or unifoliolate leaves, are the object of the present paper. Glycosmis? africana Hook.f., described from the island of São Tomé, is transferred to the genus Vepris, as V. africana (Hook.f.) O.Lachenaud & Onana, comb. nov. This species, which also occurs in Gabon, Angola and the Republic of Congo, was previously known under the illegitimate name V. gossweileri (I.Verd.) Mziray [non V. gossweileri I.Verd.]. It is here illustrated for the first time, and a complete description is presented; it is notable for having androdioecious flowers, rather than dioecious as usual in the genus. Another new combination, Vepris laurifolia (Hutch. & Dalziel) O.Lachenaud, comb. nov. – based on Garcinia laurifolia Hutch. & Dalziel – is published for a West African species, so far known under the younger synonym V. felicis Breteler. This species is newly recorded from Sierra Leone, and an updated description is presented. These two species are compared to the similar V. welwitschii (Hiern) Exell, which is endemic to Angola and still relatively little-known. The conservation status of all three species is assessed, respectively as Near-threatened (V. africana, comb. nov.), Vulnerable (V. laurifolia (Hutch. & Dalziel) O.Lachenaud, comb. nov.) and Endangered (V. welwitschii).

Glycosmis? africana Hook.f., described from the island of São Tomé, is transferred to the genus Vepris, as V. africana (Hook.f.) O.Lachenaud & Onana, comb. nov. This species, which also occurs in Gabon, Angola and the Republic of Congo, was previously known under the illegitimate name V. gossweileri (I.Verd.) Mziray [non V. gossweileri I.Verd.]. It is here illustrated for the first time, and a complete description is presented; it is notable for having androdioecious flowers, rather than dioecious as usual in the genus. Another new combination, Vepris laurifolia (Hutch. & Dalziel) O.Lachenaud, comb. nov. – based on Garcinia laurifolia Hutch. & Dalziel – is published for a West African species, so far known under the younger synonym V. felicis Breteler. This species is newly recorded from Sierra Leone, and an updated description is presented. These two species are compared to the similar V. welwitschii (Hiern) Exell, which is endemic to Angola and still relatively little-known. The conservation status of all three species is assessed, respectively as Near-threatened (V. africana, comb. nov.), Vulnerable (V. laurifolia (Hutch. & Dalziel) O.Lachenaud, comb. nov.) and Endangered (V. welwitschii).","PeriodicalId":55556,"journal":{"name":"Adansonia","volume":"78 1","pages":"107 - 116"},"PeriodicalIF":0.8,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73541306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
