nato plicato. Java. Flowers small, yellow. 



4<7. D- nudum (L. no. 49. Onychium nudum, Blume, p. 325) ; 

 foliis lineari-lanceolatis insequali-acuminatis membrana- 

 ceis, racemis paucifioris, sepalis interioribus lanceolatis 

 dorsali angustioribus. Java. Stems jointed, zig- 

 zag at the upper part. Flowers pale purple, changing

48. D. ramosum (L. no. 34) ; caulibus pendulis gracilibus 

 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. 



49. D. herbaceum (Lindl. Bot. Reg. 1840, misc. 153) ; cauli- 

 bus ramosis teretibus glabris, foliis lineari-lanceolatis 

 acuminatis apice oblique bilobis, racemo paucifloro ter- 

 minali, sepalis lateralibus basi paulo productis dorsali 

 petalisque linearibus, labello lanceolate integerrimo nudo,

Onychium rigidum^ Blume, p. 324) ; foliis lato-lanceo- 



latis oblique 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.
