"Csespitosa, 2^sendobulbis teretiusculis brevissimis, vaginis valde 

 nervosis, fo His linearibus acutis crassis (siccis convolutis), pedicel- 

 lis basilaribus hispidis longe supra bracteam exsertis, ovariis his- 

 pidis, sepalis triangulis, lateralibus in cornu seu calcar spurium 

 ipsis sequilongis extensis, omnibus extus penicillato hispidis, t&palis 

 lanceis acutis, labello longe cuneato antrorsum abrupte dilatato 

 subquadrato apice angustius triangulo limbis involutis, processubus 

 styliformibus geminis retrorsis in basi, cohimnce auribus semi- 

 oblongis. Banos Luconiae. (Flores valde vetusti. Inde subdubius 

 haereo de processubus styliformibus baseos, qui tamen vix artefacti 

 visi.) " — Reichenbach f., Otia bot. Hamb. 54. 



Pseudobulbs about 16 mm. long, fusiform, terete, slender, 

 concealed by sheathing, chartaceous bracts. Leaf 3-12 cm. long, 

 in dried specimens con duplicate, probably fleshy, semiterete and 

 strongly grooved when living. Sejoals ± 4 mm. long. Capside 

 about 8 mm. long, ellipsoidal-oblong. 



The above description is based on the fragmentary specimen in 

 the Gray herbarium — labelled vicinity of Banos, Luzon, Wilkes 

 expedition (1838-42) — which passed through H. G. Reichenbach's 

 hands. The flowers are imperfect. The following description is 

 drawn from specimens collected by Mr. R. S. Williams in central 

 Luzon, in 1904, which appear to agree with C. senilis, although 

 the leaves are much shorter, and with specimens found in Minda- 

 nao by F. H. Bolster.
