Impatiens tanintharyiensis (Balsaminaceae) is reported in Thailand for the first time from a population in Ngao Waterfall National Park, Ranong Province. This population differs from that at the type locality in Myanmar by having smaller, purple flowers (vs bigger purplish-pink flowers). An expanded description of this taxon and colour photographs are provided.

This paper presents five newly recorded species of Flemingia present in two subgenera; Flemingiastrum and Rhynchosioides. Four species are new for Thailand: F. nana, F. semialata, F. vestita and F. wallichii. One species, F. nana, is new for Myanmar, and one species, F. wightiana, is new for Laos. Two taxa, F. brevipes and F. latifolia var. siamensis, are synonymised under F. macrophylla. Detailed morphological descriptions and colour photographs are provided. A key to the species in Flemingia subgenus Flemingiastrum for Thailand is provided.

A revision of the genus Beilschmiedia (Lauraceae) from Thailand and Indochina is presented with a summary of its taxonomic history, plus keys, full descriptions of each species, distribution maps, conservation assessments, ecological information, ethno-botanical notes and a discussion of its morphology. In this treatment, 21 species are recognized; 14 names are lectotypified (B. argentata, B. balansae, B. balansae var. muticarpa, B. clarkei, B. elegantissima, B. ferruginea, B. globularia, B. glomerata var. tonkinensis, B. lucidula, B. obovalifoliosa, B. palembanica, B. poilanei, B. sphaerocarpa and B. wightii), five names are placed into synonymy for the first time, and B. laotica Kosterm. ex de Kok is validly published here for the first time. In addition, one new variety (B. percoriacea var. percoriacea de Kok) is proposed and one new combination (B. percoriacea var. glaucoides de Kok) is made. Nine species are considered to be Least Concern, one is Critically Endangered, five are Endangered, and five are listed as Vulnerable.

Following recent studies showing that Asian Schefflera should be treated under the separate genus Heptapleurum, the names for the Thai species belonging to this genus are listed. Two new combinations are proposed for S. bengalensis and S. poomae. For two species of Schefflera recognized, S. pueckleri and S. simulans, different epithets must be used under Heptapleurum, namely H. calyptratum and H. affine.
