ORCHIDACE^ 



oblique thickened ridge ; middle lobe subulate, in natural position 

 arcuate-decurved, fleshy, about 1.5 mm. long when expanded, 

 sulcate, obtuse, at the base terminating within the spur in an 

 upcurved fleshy cylindrical tubercle which is about .5 mm. long; 

 spur about 5.5 mm. long, when viewed from the side forming an 

 obtuse angle in the middle, obliquely laterally compressed to 

 about the middle, then abruptly dorso-ventrally compressed and 

 provided on the anterior surface with a deep groove, apex broadly 

 rounded. Column short, fleshy, about 1.8 mm. high, viewed from 

 the side subquadrate-malleoliform, furnished with a minute tu- 

 bercle at the base. Anther pileate. Pollinia two, subglobose, on 

 the apex of a slender membranaceous cuneate-dilated stipe which 

 is about 2.2 mm. long. 



A great range of vegetative variation is shown by the collec- 

 tions of this plant. Clemens 87 exhibits longer stouter roots, a leaf 

 measuring 12.3 cm. long and 2.84 cm. broad, and a scape about 

 33 cm. long; Clemens 133 is a small immature plant showing 

 one leaf 5.4 cm. long and 9.5 mm. broad; Clemens 353 displays a 

 stem ±20 cm. tall with evidences of thirteen leaves; Clemens 176 

 shows a leaf 3.1 cm. broad. 



This plant is very close to Malleola Jf^itteana J. J. Sm. & 



Schltr., but it differs from that species in being much less stout 



and fleshy, in having the leaves longer in proportion to breadth, 



in the decurved middle lobe of the lip and in the color of the 



flowers. (Plate 96.)
