more than 6 inches in length, but far fewer than in either G. 

 exilis or aphylla. Each stem bears one or two short flower- 

 racemes, and the withered remains of some of previous years' 

 growth. The flowers, 11 or more to a raceme, are supported on 

 very slender pedicels ^ an inch in length, with small ovate 

 spreading bracts. The column is larger than usual, and of 

 very thin consistency. The anther is large and firmly attached 

 to its filament, and, as in the other species of the genus, is 

 prolonged in front into a sharp beak, which lies over the long 

 rostellum. The pollinia are small, but the caudicle is long and 

 slender, slightly dilated at the upper part, and bearing a small 

 oblong gland. The rostellum is oblong and bent downwards 

 over the stigma, and ends in two flat narrow lobes projecting 

 outwards over the entrance of the spur, and slightly curved up 

 at the end.

This plant is distinguished from the nearly allied G. exilis by 

 the shorter and denser racemes, longer stem, fewer and stronger 

 roots, and larger flowers, with a clavate spur. The pedicels of 

 the flowers are 3 millim. long, the petals and sepals 1^ millim., 

 equalling the spur. Thouars figures the flowers as white; Moore 

 states that they are reddish.
