Bhacteate Habexahia. 



Root perennial, a fascicle of short thick fleshy fibres, and sometimes tubers. 

 Siem 6 to 9 inches high, smooth, leafy, sheathed at base. Leaves about 3, al- 

 ternate an inch and half to near 3 inches long, and half an inch to an inch 

 wide elliptic-lanceolate, acute (sometimes the lower one ©pattilate-obovate and 

 obtuse), smooth, sessile and sheathing at base. Flowers small, in a terminal 

 bracteaic spike 2 to 3 inches in length ; bracts linear-lanceolate, veined, the lower 

 ones about twice as long as the dowers, the upper ones scarcely longer. Seg- 

 ments of the perianth pale green, considerably shorter than the lip, the lateral 

 outer ones obliquely ovate; lip oblong, sometimes spatulate-linear, depending, 

 3-toothed at apex, the middle tooth very short, or obsolete ; spur scarcely half M 

 .ongasthe lip, inflated or saccate, and apparently didymous or 2-lcted.

 bract-like ones above, sheathed at base. Lower leaf 3 to 5 inches long, and near
