All species of the flowering plant genus Cremastosperma (Annonaceae)
We present a taxonomic revision of Cremastosperma, a genus of Neotropical Annonaceae occurring in lowland to premontane wet forest, mostly in areas surrounding the Andean mountain chain. We recognise 34 species, describing five as new here: from east of the Andes, C. brachypodum Pirie & Chatrou sp. nov. and C. dolichopodum Pirie & Maas sp. nov., endemic to Peru; C. confusum Pirie sp. nov., from southern Peru and adjacent Bolivia and Brazil; and C. alticola Pirie & Chatrou sp. nov., at higher elevations in northern Peru and Ecuador; and from west of the Andes, C. osicola Pirie & Chatrou sp. nov. endemic to Costa Rica, the most northerly distributed species of the genus. We provide an identification key, document diagnostic characters and distributions and provide illustrations and extensive lists of specimens, also presenting the latter in the form of mapping data with embedded links to images available online. Of the 34 species, 22 are regional endemics. On the basis of the extent of occurrence and area of occupancy of species estimated from the distribution data, we designate IUCN threat categries for all species. Fourteen species proved to be endangered (EN) and a further one critically endangered (CR), reflecting their rarity and narrow known distributions.

|經費來源||MDP is supported by a Heisenberg Fellowship from the Deutsche Forschungsgemeinschaft (PI 1169/2-1); funding for fieldwork was provided by the Nederlandse Organisatie voor Wetenschappelijk Onderzoek (Grant: R 85-351)|
During multiple field trips since 1971 (PJMM); 1994 (LWC); and 2001 (MDP)] to localities in Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Boliva, Panama and Peru, we have observed species of Cremastosperma, making herbarium vouchers, taking photos, preserving flowers and fruit in alcohol and, in the last 20 years, drying leaf samples in silica gel for DNA extraction. We studied specimens representing 1037 individual collections from herbaria A, AAU, AMAZ, B, C, CAY, COL, CUZ, ECON, F, G, GB, GH, HAO, HBG, HOXA, HUA, HUT, INB, K, L, LE, LPB, M, MICH, MO, MOL, NY, OXF, P, QAME, QCA, QCNE, RB, S, U, UC, US, USM, USZ, VEN, WIS, WU and Z.
|研究範圍||We documented as many herbarium specimens of Cremastosperma as possible, from across the entire geographic distribution (Neotropics: from southern Costa Rica in the north to Bolivia in the south).|
|品質控管||We determined each specimen to species, or in doubtful cases to "sp."|
- We curated the collections data using BRAHMS version 7.9.9 (http://herbaria.plants.ox.ac.uk/bol/).

|目的||The dataset was compiled as the basis for a taxonomic revision and evolutionary research into Cremastosperma (Annonaceae)|
