Recent studies have suggested that the closely related Neotropical genera Desmopsis Saff. and Stenanona Standl. (Annonaceae) are non-monophyletic and would be better considered as a single genus Desmopsis. The transfer of species currently circumscribed in Stenanona necessitates 14 new combinations and two new names in Desmopsis.

We describe and illustrate the new species Senecio basipectinatus J. Calvo & Callm. (Compositae) endemic from the Befotaka-Midongy du Sud Protected Area in southeastern Madagascar. The new species is compared with the morphologically most similar taxon S. vaingaindrani Scott Elliot. The taxonomic circumscription of the latter species is further revised and its variety concolor Humbert is newly synonymized.

Piper alwynii M. A. Jaram. (Piperaceae), a new species occurring in sandstone outcrops of the Cordillera del Cóndor at the border of Ecuador and Peru, is here described and illustrated. Morphologically it shows similarities to species in the Radula clade. Piper alwynii is similar to P. purdiei C. DC. but differs in having leaves pinnately nerved within the lower two thirds of the midvein, nerves pubescent on the abaxial surface, villous peduncles, and spikes 2–2.7 cm long. An identification key for 32 northern South American Piper L. species with small (≤ 10 cm) leaves is presented.

Preparing the Malpighiaceae treatment for an upcoming volume of the Flora Mesoamericana has revealed a number of new species, new combinations, and typifications of taxa from different genera of Neotropical Malpighiaceae requiring publication. Nine new species are proposed in this paper from the Mesoamerica flora area: three Bunchosia Kunth (B. bifurcata A. Pool, B. chiapensis A. Pool, and B. heterotricha A. Pool), one Carolus W. R. Anderson (C. yucatanensis A. Pool), one Glicophyllum R. F. Almeida (G. mortonianum A. Pool), two Malpighia L. (M. inclinata A. Pool and M. verrucifolia A. Pool), one Psychopterys W. R. Anderson & S.

Five new species of Aniba Aubl. (Lauraceae) with clustered or verticillate leaves are described and illustrated. Aniba brochidodroma van der Werff from Peru stands out by its short petioles and soft whitish hairs on the lower leaf surface. Aniba glabra van der Werff from Colombia is distinguished by its glabrous flowers and inflorescences. Aniba palaciosii van der Werff from Ecuador can be recognized by the indument of the outer surface of the tepals, with the outer three tepals finely appressed pubescent and the inner three tepals glabrous. Aniba tomentella van der Werff from Peru differs from its congeners in its flower shape; its flowers are wider than long and the tepals are incurved leaving only a small apical pore. Finally, A. verticillata van der Werff from Ecuador differs from morphologically similar species by its subcoriaceous leaves with prominently raised secondary veins and its montane habitat.
文章题目阿尼巴五新种。(樟科)具有簇生或轮生叶描述和说明。秘鲁的阿尼巴(Aniba brochidodroma van der Werff)以其短叶柄和叶下表面柔软的白色毛而引人注目。来自哥伦比亚的Aniba glabra van der Werff以其无毛的花和花序而闻名。来自厄瓜多尔的Aniba palaciosii van der Werff可以通过被花被片外表面的凹陷来识别，外三层被花被片被细贴伏短柔毛，内三层被花被片无毛。来自秘鲁的阿尼巴(Aniba tomentella van der Werff)在花的形状上与其同类不同;它的花宽大于长，花被片弯曲，只留下一个小的顶部孔。最后，厄瓜多尔的A. verticillata van der Werff与形态相似的物种的不同之处在于它的皮质下叶具有明显凸起的次脉和它的山地栖息地。

The Malagasy species of Casearia Jacq. (Salicaceae) have no modern taxonomic treatment and present particular difficulties due to their similar flowers. Twentieth-century authors have adopted overly lumping classifications featuring broad circumscriptions of C. nigrescens Tul. Perrier de la Bâthie published three varieties within C. nigrescens sensu Tulasne: varieties onivensis H. Perrier, ovata H. Perrier, and subtrinervia H. Perrier. All of these are from eastern humid forests, farther inland and at higher elevations than is typical of variety nigrescens s. str. Study of the available specimens indicates that all are sufficiently distinct from variety nigrescens that they should be elevated to the rank of species. They are herein recognized as C. onivensis (H. Perrier) Ang. X. Wang & Philpott, C. angustifructa Ang. X. Wang & Appleq., and C. subtrinervia (H. Perrier) Ang. X. Wang & Appleq., respectively. All are rarely collected, and preliminary assessment of their conservation status suggests that all three are Endangered.
马达加斯加稻壳属的一种。(水杨科)没有现代分类学处理，由于它们的花相似，目前特别困难。二十世纪的作者们采用了过于集中的分类，其特点是黑孢菌的范围很广。Perrier de la bthie发表了图拉斯纳黑桫椤的三个变种:onivensis H. Perrier、ovata H. Perrier和subtrinervia H. Perrier。所有这些都来自东部潮湿的森林，更远的内陆，海拔比典型的黑枝属s.s r r高。对现有标本的研究表明，所有这些都与黑枝属品种有足够的区别，它们应该被提升到物种的等级。它们在这里被认定为C. onivensis (H. Perrier) Ang。王晓霞&;Philpott, C. angustifruta Ang。王晓霞&;Appleq。和C. subtrinervia (H. Perrier) Ang。王晓霞&;Appleq。,分别。它们都很少被收集，对它们的保护状况的初步评估表明，这三种物种都是濒危物种。

Sciodaphyllum montanum Idarraga, Jimenez-Mont. & Lowry and S. undulatum Jimenez-Mont., Idarraga & Lowry (Araliaceae) from the northern region of the Central and Western Cordilleras of the Andes in Colombia are described and illustrated. Sciodaphyllum montanum differs from other members of the genus mainly by a bulging disc up to 1.1 mm in height and a 3- to 4-carpellate ovary, and S. undulatum is distinguished by its undulate leaflet margin and the conspicuous scarlike amorphous lenticel 4.9–11 mm in diameter located abaxially on the base of the petiole. Notes are provided on possible taxonomic affinities of each species, as well as on their ecology and geographic distribution. Extinction risk assessments are given following the IUCN Red List categories and criteria, which indicate that both S. montanum and S. undulatum are Near Threatened (NT).
