Abstract. Saensouk P, Saensouk S. 2021. Taxonomic studies and three new records on genus Geostachys (Baker) Ridl. in Thailand. Biodiversitas 22: 3057-3067. A comprehensive taxonomic study and three new records of genus Geostachys (Baker) Ridl. in Thailand have not been reported. This research aimed to study the taxonomical aspect of the genus Geostachys in Thailand based on herbarium collections, fresh materials, and available literatures. Nine species of Geostachys have been recognized with their updated nomenclature in Thailand, namely G. angustifolia K. Larsen, G. chayanii Mayoe, G. decurvata (Baker) Ridl., G. holttumii K. Larsen, G. kerrii K. Larsen, G. penangensis Ridl., G. pierreana Gagnep., G. smitinandii K. Larsen, and. G. tratensis Picheans. & Mayoe. Three species, namely G. decurvata, G. pierreana, and G. penangensis are found to be new records to Thailand. Six species, namely G. angustifolia, G. chayanii, G. holttumii, G. kerrii, G. smitinandii, and G. tratensis were endemic to Thailand. The identification key to species, detailed descriptions, photographs, vernacular name, geographical distribution, ecology, phenology, conservation status, and taxonomic notes have been provided.

Abstract Ichthyofauna surveys in Diyung, Vomvadung, Khualzangvadung, Tuikoi, and Mahur rivers under Dima Hasao District of Assam resulted in the first report of 21 species of fish belonging to 19 genera, eight families, and four orders. These include Cypriniformes, Siluriformes, Synbranchiformes, and Perciformes. The species composition is highest in Vomvadung River with 11 species, followed by Diyung with eight species, Khualzangvadung with six species, Mohur with three species, and Tuikoi with two species. The conservation status of Systomus clavatus, Tor tor, Neolissochilus hexagonolepis, Neolissochilus hexastichus is near threatened, and Pterocryptis barakensis is endangered.

First Time

During a taxonomic study on Croton sect. Geiseleria from Brazil, 40 specimens were found from the southern portion of the Brazilian Amazon that correspond to C. hadrianii, a species hitherto known only from its original description and with the type locality within Brazil unknown. We present an amended description of C. hadrianii providing the first information on fully developed fruits and seeds, which previously undocumented, morphological characterization, as well as comments on its geographical range, including a distribution map, conservation status, and period of flowering and fruiting. The species is also illustrated and photographs in its habitat for the first time. Typification is also presented and the species systematic position within Croton sect. Geiseleria is discussed. Additionally, we provide a key to the 16 species of Croton sect. Geiseleria occurring in the Brazilian Amazon, as well as field images for most of them.

A revisional taxonomic study of Adesmia subg. Adesmia ser. Bicolores has unveiled a new species from southern Brazil. Adesmia miottoae is described and illustrated here. Its geographic distribution, phenology, conservation status and morphological similarities with its closest relatives, Adesmia punctata and A. incana, are presented. The species is distinguished by glandular trichomes covering all the aerial parts of the plant, except the corolla. These trichomes are shorter than those of Adesmia punctata. Additionally, a detailed anatomical description of the leaflet blade is provided.

(On the taxonomic identity and conservation status of Campomanesia ilhoensis Mattos and C. viatoris Landrum (Myrtaceae)). Based on a taxonomic study of Campomanesia Ruiz & Pavón in the state of Bahia, Brazil, we observed that C. ilhoensis Mattos and C. viatoris Landrum belong to the same taxonomic entity. Both names are legitimate and validly published; however, C. ilhoensis has priority over C. viatoris, which has been in use since 1984. In addition, the distribution of the more inclusive species is now known to extend from Bahia to Ceará. A new conservation status for this species is suggested because of a better knowledge of its distribution.

During a taxonomic study of Euphorbia from Goiás state, Brazil, we came across some small populations of an unfamiliar species of the genus in the Chapada dos Veadeiros region. After detailed analyses of these specimens we concluded that they correspond to E. burchellii (E. section Anisophyllum), a species hitherto known only from its type locality. We present an amended description of E. burchellii, provide the first information about its fruits and seeds, as well as its lectotipification. We also include illustrations and field photographs, comments on its geographical range along with a distribution map, a recommendation for conservation status, phenology, morphological relationships, and systematic position. Finally, we also provide a key to the 14 species of E. section Anisophyllum occurring in Goiás State.

Casearia Jacq. (Salicaceae) in Madagascar is in need of taxonomic study. We identify two new species that are endemic to small regions of Madagascar and that, by virtue of their unusually small leaves and other characters, are clearly distinguished from all previously described taxa. Casearia anosyensis Appleq. & M. T. Gates is endemic to a small region near Tôlanaro in the southeast, at low elevations; it is considered to be Endangered by IUCN criteria. Casearia montigena Appleq. & M. T. Gates is found in montane environments in the extreme north, usually at high elevations; its conservation status is uncertain.
