Characterized by its small glabrous capsules, small entire leaves, and 
small sepals. The petioles are less conspicuously winged than those of 
H. sinensis Dunn. The genus is new to Indo-China, the species on pre- 
liminary identification having been referred to the very closely allied 
genus Séewartia. Hartia tonkinensis is apparently most closely allied to 
H. micrantha Chun of Kwangtung Province, China. 
In connection with this item the following adjustment is desirable in 
MERRILL, INDO-CHINESE PLANTS 5) 
connection with another Kwangtung species which has been described 
under different names in both Æartia and Stewartia:
