nato plicato. ——Java.—— Flowers small, yellow. 
47. D. nudum (L. no. 49. Onychium nudum, Blume, p. 325); 
foliis lineari-lanceolatis insequali-acuminatis membrana- 
ceis, racemis paucifloris, sepalis interioribus lanceolatis 
dorsali angustioribus.———Java.——Stems jointed, zig- 
zag at the upper part, Flowers pale purple, changing

ramosis glabris, foliis lanceolatis acuminatis apice inte- 
gerrimis, floribus subracemosis, bracteis membranaceis 
reflexis obtusis, sepalis lateralibus magnis in cornu elon- 
gatum rectum connatis, petalis minoribus, labello cucul- 
lato acuto crispo.— — India. This plant is only 
known by some imperfect specimens distributed by 
Dr. Wallich. It is much more slender than D. Pierardi, 
has an evident tendency to branch, and appears to be a 
distinct species. It however requires further examina- 
tion. It is near D. herbaceum ; but the flowers have a 
long and conspicuous spur.

Onychium rigidum, Blume, p. 324); foliis lato-lanceo- 
latis obliqué retusis rigidis.— Java. Flowers 
whitish, with three yellow glands, Dr. Blume doubts 
whether it may not be a variety of his D. mutabile, but 
he says that its parts are more firm.
