On some Plants in the H. C. Botanic Gardens. 371 



tentibus, floribus racemosis, labello spathulato emarginato 

 plicato-undulato fundo sub-tricristato. 



Habit. — On trees. Ayer Punnus (Rhim), Malacca. 



Descr. — A slender species not exceeding a foot in height. Stems 

 very flexuose, very attenuate. Leaves many times longer than 

 broad. Flowers small. Petals linear spathulate, very narrow. 



In general size this approaches to the Assam specimens 

 of A. acinaciforme : it appears to be distinguished from all 

 others, (setting aside Blume's species, the characters of 

 which are quite insufficient,) by the narrow subterete, dis- 

 tant leaves.
