A species which is very rarely met with in our collec- 

 tions, and remarkable in the genus for an aggregated sub- 

 sessile inflorescence, issuing from the bosom of the upper- 

 most leaf on the stem, separated at the base by small en- 

 closed spathaceous bractes, and standing upon very short 

 nearly obsolete pedicles. 



Flowers several, an inch and half long, upright, of agrcen- 



ellow colour. Stem simple, little more than half a foot 



high, sheathed the whole* length by the lower attenuated 

 portion of the leaves; these alternate, distich, patent, ob-

 Indies, where it grows on the trunks of trees, sometimes 



horizontal lv, sometimes perpendicularly downward*, lu-
