GYNANDRIA— MONANDRIA. Listera. 39 



nected, in small bundles, by one common fibre. Stems solitary, 

 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 slen- 

 der, and dovvny, terminating in a long duster of very numerous 

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

 the partial stalks. Cat. 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 terminates in a 

 concave, obovate, hood-like appendage, which seems peculiar to 

 this species. Each mass of pollen is cloven, or double. Caps. 

 roundish. obovate. Seeds each with a pale taper tunic, greatly 

 lengthened out at the ends. 

 In E)igl. Bot. the upper lip of the stigma is, by mistake, called the 

 lower lip of the column.
