ABSTRACT Dendrobium petrophilum (Kraenzl.) Garay ex N.Hallé was a species only known from the type specimen and was considered doubtful. Since it has been recently relocated in its type locality and in its surrounding areas, we were able to compare it to the endemic closely related and well known species, Dendrobium oppositifolium (Kraenzl.) N.Hallé. We confirm D. petrophilum as a distinct species based on its morphology and its very special ecology. Both species are fully described, compared, and illustrated. Comparative tables are given in English and French. We also discuss their ecology, distribution, phenology and confirm the IUCN assessments made by the local Endemia Red List Authority.
嗜石斛(Dendrobium petrophilum)Garay ex n . hall是一种仅从模式标本中知道的物种，被认为是可疑的。由于它最近被重新安置在它的类型位置和周围地区，我们能够将它与地方性的密切相关和众所周知的物种，石斛(Dendrobium oppositifolium (Kraenzl))进行比较。N.Halle。我们根据其形态和非常特殊的生态环境，确认了d.p otrophilum是一个独特的物种。这两个物种都得到了充分的描述、比较和说明。比较表以英文和法文提供。我们还讨论了它们的生态、分布、物候，并确认了当地地方性物种红色名录权威机构所做的IUCN评估。

ABSTRACT Coffea rizetiana Stoff. & M.Noirot, sp. nov., a diploid species only known from a single wild population in South-West Cameroon, is formally described here. It is probably extinct in the wild, but is present in the germplasm collection in Bassin Martin (Réunion, France) and Meise Botanic Garden (Belgium). Phylogenetic analyses reveal a close relationship with C. montekupensis Stoff., a species endemic to the same region but occurring at higher elevations, and with C. liberica Bull. ex Hiern, a species with a wide Central and West African distribution. The new species can be distinguished from other Coffea species from Central Africa by its large black fleshy fruits with thick mesocarp. It can be differentiated from its close relative C. montekupensis by its larger less obovate leaves, longer corolla tube and larger fruits; and from C. liberica by its shorter petiole, acuminate leaf tip, cuneate leaf base, thinner leaf blade, shorter corolla tube, longer corolla lobes and black fruits with a thick fleshy pericarp. The evolutionary importance of the fruit colour is discussed, as well as the role of Mount Kupe, the Bakossi Mountains and the broader South-West Cameroon region as the principal Coffea diversity hotspot on the African continent.

RÉSUMÉ Le genre Coelospermum Blume est un groupe d'espèces de Rubiaceae du Sud-Est asiatique, d'Australie et d'Océanie qui comporte onze espèces généralement lianescentes. Au sein de la tribu des Morindeae, Coelospermum se différencie par ses fleurs à étamines nettement exsertes. En Nouvelle-Calédonie, seules trois espèces étaient jusqu'ici connues, auxquelles une quatrième est ici ajoutée, qui s'en distingue aisément par ses fruits syncarpiques et sa corolle à gorge et lobes en face interne densément pileux. Cette espèce nouvelle, appelée C. nomac sp. nov., est endémique de Nouvelle-Calédonie et plus particulièrement micro-endémique à l'extrême Nord, sur le massif de Tiébaghi et à la Pointe Nord de l'Île. Le faible nombre de récoltes disponibles ainsi que les efforts de prospections, restés vains, de 2019 et 2020 sur Tiébaghi montre que cette liane reste relativement rare et doit faire l'objet d'une évaluation de menaces et de conservation. La catégorie CR « en danger critique d'extinction» est provisoirement proposée. Parmi les trois autres espèces, une étude taxonomique suggère l'usage d'un autre nom pour C. monticola, C. fragrans qui est ici néotypifié.

ABSTRACT Faced with ambiguities in a previous typification of Isochilus pauciflorus Cogn., we present a revised typification of this name and comment on its synonyms. Our current study reviews the original materials in open databases of the 23 main herbaria that house orchids from A. Duss, A. Cogniaux or H. G. Reichenbach. Among specimens filed as types, a lectotype (BR0000013217891) is recognized and a presumed isotype (NY00059032) is rejected. However, the lectotype material is not sufficient for precise application of the name. Thus, we designate an epitype based on the specimen K000079638 which refers to the heterotypic synonym Ponera punctulata Rchb. f. to support the name I. pauciflorus. Furthermore, the holotype of P. punctulata commonly accepted and used in the literature is said to be in the Reichenbach Orchid Herbarium, at the Natural History Museum in Vienna (Austria). Unfortunately, this unique gathering is no longer extant or is missing there, but a photograph is available. From this picture, we show that this specimen was not original material, so it was not the holotype. We therefore designate a neotype of P. punctulata Rchb. f. supported by the specimen K000079638. In addition, we designate an epitype of Tetragamestus isochiloides Regel (LE00011188), heterotypic synonym of these above taxa. Finally, the type of Hexadesmia dunstervillei Garay, AMES00287200, is demonstrated to be a lectotype, not a holotype.
摘要:在以往的少花等香属分类中存在歧义。，我们提出了这个名字的修订类型和评论其同义词。我们目前的研究回顾了23个主要植物标本的开放数据库中的原始资料，这些植物标本来自A. Duss, A. Cogniaux或H. G. Reichenbach。在作为类型提交的标本中，识别了一个lectotype (BR0000013217891)，拒绝了一个假定的同型(NY00059032)。然而，原型材料不足以精确应用该名称。因此，我们在标本K000079638的基础上指定了一个表型，该表型指的是异型同义Ponera punctulata Rchb。1 . pauciflorus;此外，文献中普遍接受和使用的马斑兰的完整模式据说在维也纳(奥地利)自然历史博物馆的赖兴巴赫兰花标本馆。不幸的是，这个独特的聚会已经不存在了，或者在那里失踪了，但是有一张照片可以找到。从这张图片中，我们可以看出这个标本不是原始材料，所以它不是原型。因此，我们指定了一种新种。f.由试件K000079638支撑。此外，我们还指定了一个异chiloides Regel (LE00011188)的表型，它是上述分类群的异型同义物。最后，证明了Hexadesmia dunstervillei Garay的类型，AMES00287200是一个集合型，而不是一个完整型。

ABSTRACT Several new Combretum Loefl. (Combretaceae) collections from Central Africa have revealed a taxonomical confusion in that genus. To correct these mistakes two species, C. pellegrinianum Exell and C. littoreum (Engler) Engler & Diels, are resurrected and one variety, Quisqualis falcata var. mussaendiflora (Engl. & Diels) Liben, is transferred again to species level as C. mussaendiflorum Engl. & Diels. The related Combretum baldwinii Jongkind, sp. nov. from Nigeria is here newly descibed. The species included in this review have in common that they have an upper receptacle that is several times as long as wide, stamens that are not or slightly exserted and a style that is conspicuously adnate to the upper receptacle for an important part of its length. All these species, except the new one, were formerly included in the genus Quisqualis L.

ABSTRACT A new species, Solanum pulneyensis Soosairaj, sp. nov. (Solanaceae) is described from the woody savanna forest of Palani Hills National Park, Tamil Nadu, India. This species is unusual and special as it has subcapsular fruits unlike other Indian Solanum L. species that have berry fruits besides being entirely enclosed within persistent calyx as that of S. wightii Nees. A detailed morphological description with line drawings is provided here.

ABSTRACT The diversity of the floral characters in 25 species of Brassicaceae representing seven tribes was studied through tracing their floral organs vascularization. The aim of the present study is to explore the contribution of the micro-floral characters in understanding the relationships among the studied species of Brassicaceae as well as the evolutionary trends in calyx, corolla, androecium and gynoecium. It was concluded that the vascularization of sepals, petals, stamens, nectaries and carpels was considered diagnostic and reliable characters at the specific level. The reduction and presence of vascular complexes was found to be at the top of the floral evolutionary trends. The micro-floral data were discussed in the view of dicta of evolution which facilitate the construction of proposed schematic presentation showing the line of advancement within each tribe. The line of advancement in tribe Brassiceae (representing 14 studied species) is from the primitive Raphanus sativus L. to the advanced Eruca sativa Mill. To rule the line of evolution within other tribes, the number of studied taxa should be increased.
