ORCHIDACEiE 



1.8 cm. long, 2.6 cm. broad between the apices of the lateral 



lobes, with a group of three fleshy closely approximate united 



semi-orbicular erect keels in the center of the lamina; lateral 



lobes about 9 mm. long, 7.5 mm. wide at the base of the free 



portion, triangular, obtuse; middle lobe appearing deltoid in 



natural position with lateral margins decurved, when spread out 



about 7 mm. long, 8 mm. broad at the base, ovate-Ungulate to 



ovate-triangular, broadly rounded. Column about 1.5 cm. long, 



very stout, strongly arcuate, subclavate, concave on the anterior 



face, strongly convex on the posterior surface, inconspicuously
