PONERA. ORCIIIDES. 451 



This diflfers from ihe preceding In the lip being two-lobed , not acute Dnd recurved. 

 in its margins being entire, and not crenulated. in the antlier bed havi^ig a dorsal 

 tooth. which curves ovcr the anther , and 2 much smaller blunl teetli on each 

 side of the stigma; it has also ihe propcrty of llowering on tlie old leafless stems 

 instead of the young leafy ones. The flowers are pale bulT, striped wilh brownish 

 orange. 



Roots of Neottia, a slender stem 3—4' high, unbranched, and covered with narrow 

 grassy leaves . from 4-six inches long . the points of which are obliquely emar- 

 ginaled and the sheaths rough, like ihose of Arpophyllum wilh little green or purplc 

 tubercles. When old ihe stenis become leafless , are closely covered with rugged 

 sheaths and produce here and there from their axils clusters of 2 — 3 sessile 

 flowers of a pale buff colour, and less ihan half an inch long. In form tliey are ex- 

 aetly like a Maxillaria or a Dendrobium ; boih sepals and petals boing striped with 

 bright reddish brown. The column is short , taper , with a pair of small auricles 

 on each side of the anther bed, and a dorsal tooih curved over the anthcr, which 

 is membranous, 4 celled, and contains 4 pollenniasses , adhering in pairs by means 

 of single straps of powdery matter. The labelliim is wedgcshaped . slightly downy 

 downwards in ihe middle and twolobed at the apex. 



Paxt. Fl. G. II. p. 29. Xyl. 149. Flowers pale green. Guatemala. Grassy leaves 

 upon stems nbout 2 feet high ; and when old throvvs out its flowers chiefly from 

 the old lentless branches. The flowers are pale watery green , not unlike ihose of 

 some iMaxillaria especially in the extended column base, wilh which the lip is joinind ; 

 but the pollenmasses have the pulverulent caudicles of an Epidendrum. The lip is 

 truncate as it werc, and iwo lobed, the one lobe overlapping the other.
