419. APL-EC'TRtntl, Nuttall. 

 [Qr. a, privative, Plektron, a spur, the lip not being spurred.] 

 Lip 3-ridged, with a short claw, and no trace of a spur at base. 

 Anther subterminal (i. e. slightly below the apex of the column) ; 

 pollinia 4, oblique. Rhizoma a globular solid bulb, or corm, con^ 

 nected with an exhausted one ; scape sheathed, with a solitary leaf 

 inserted on the bulb ; flowers racemose, dingy purplish-brown. 



1. A, liyeili iUe, Nutt. Leaf elliptic, acute at each end, petiolate, 

 green, sub-plicate, striate with many white nerves. 

 WINTER APLECTRUM. Adam and Eve. Putty-root. 



Bulbs half an inch to an inch, or more, in diameter, generally in pairs (some- 

 times 4 or 5,) connected by a coarse fleshy horizontal fibre. Leaf 3 to 6 inches 

 long, the white nerves converging at each end ; petiole 2 to 3 inches in length, 

 inserted on the bulb a little distant from the scape. Scape 9 to 15 inches high, 

 purplish-brown, with about 3 loose striate sheaths, the lowest one proceeding from 

 the bulb. Flowers subsessile in a terminal bracteate raceme; bracts linear-lance- 

 olate, small. Capsule ovoid-oblong, smooth, rather large. 

 Hob. Rich woodlands : not very common. FL May. Fr. Oct. 



Obs. The arid silvery-nerved leaf lives through the winter, and 

 serves, at all times, to distinguish the plant, at a glance, from the 

 Corallorhizas to which, in its scape and inflorescence, it has much 

 resemblance.
