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 Tolanaro 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. [ABSTRACT FROM AUTHOR]

This paper deals with 20 names of species and infraspecific taxa of Salix L. that Fang and Skvortsov validated or intended to validate in 1998 following their original publication by Hao in 1936 without Latin diagnoses. The names are listed and issues of typification, attribution, and synonymy are discussed. New lectotypes are designated for eight names whose holotypes have been lost or destroyed or for which a choice between syntypes was necessary: Salix acuminatomicrophylla K. S. Hao ex C. F. Fang & A. K. Skvortsov, S. atopantha C. K. Schneid. var. glabra K. S. Hao ex C. F. Fang & A. K. Skvortsov, S. calyculata Hook. f. ex Andersson var. glabrifolia Hand.- Mazz. [[ S. crenata K. S. Hao], S. forrestii K. S. Hao ex C. F. Fang & A. K. Skvortsov, S. kansuensis K. S. Hao ex C. F. Fang & A. K. Skvortsov, S. ovatomicrophylla K. S. Hao exC. F. Fang&A.K.Skvortsov, S. pseudowolohoensis K. S. Hao ex C. F. Fang & A. K. Skvortsov, and S. schneideriana K. S. Hao ex C. F. Fang & A. K. Skvortsov. The type citation of S. shansiensis K. S. Hao ex C. F. Fang & A. K. Skvortsov is corrected. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
