38 GYNANDRIA— MONANDRIA. Listera. 



nected, in small bundles, by one common fibre. Stems so- 

 litary, from 1 to 2 feet high, straight, bearing about the middle 

 2, rarely 3, sessile, elliptical, smooth, spreading leaves, each 

 with 3, 5, or more ribs. The stem above their insertion is more 

 slender, and downy, terminating in a long cluster of very nu- 

 merous green Jlowers. Bracteas ovate, pointed, smooth, shorter 

 than the partial stalks. Cal, somewhat tinged with brown. 

 Pet. and lip light green ; the latter without any lobes at the 

 base ; its disk marked with a honey-bearing furrow, evidently 

 justifying the name of nectary for this part. The column termi- 

 nates in a concave, obovate, hood-like appendage, which seems 

 peculiar to this species. Each mass o( pollen is cloven, or double. 

 Caps, roundish-obovate. Seeds each with a pale taper tunicy 

 greatly lengthened out at the ends. 

 In Engl. Bot. the upper lip of the stigma is, by mistake, called the 

 lower lip of the column.
