 pedicels, flowers small ochroleucous, lip oblong obtuse concave crenulate, sepals and 

 petals subequal lanceolate, base hardly saccate. NEPAL, Wallich. Perhaps an Eri.i ; 

 it must be in Wallich's collection, but I do not recognize it.

 haves narrow cuneate-ligulate 2-toothed, peduncle 2-fld., sepals ligulate obtusely

D. VEXABILE, Reichb. f. in Gard. Chron. 1881, i. 271, is a doubtful species or 

 hybrid, something like D. Ruckeri, very imperfectly described. It was seen by 

 Prof. Reichenbach in Low's nursery amongst a multitude of D. luteolum. Nothing 

 further is known of it. 



9. BUXiBOPHYXiXiUIK, Thouars. 



Pseudobulb from a creeping rhizome (rarely 0), 1- very rarely 2-leaved. 

 Scape from the base of the pseudobulb, rarely distant from it. Flowers 

 solitary, capitate, umbelled, spicate or racemose. Sepals subequal, or the 

 dorsal rather shorter (rarely only half as long), lateral adnate to the foot 

 of the column. Petals various, usually much smaller than the dorsal sepal. 

 Li I) jointed on the foot of the column, mobile, usually very smill and 

 strongly recurved. Column very short, often 2-ari.state at the top; author
