242 MR. HENRY RIDLEY ON ORCHIDEZ AND 
Botanic Garden. The species somewhat resembles the last, 
but differs in the form of the pseudo-bulb, which is oval in 
section, and in the form of the lip, which has the strongly 
plicate edge of D. Kunstleri, Hook. f. The flowers are as incon- 
spicuous as those of D. pallidiflorum, Ridl., the sepals and 
petals being of a dull green more or less spotted with pink, 
the lip white. They have a scent of cloves. 
I received also from native collectors a similar plant from 
Djainbi, in Sumatra, which differed shghtly in the less plicate 
edge of the lip, broader terminal lobe with a short mucro in 
the notch, and broader sepals; the flowers were entirely cream 
colour except for the emerald-green anther.
