Mill at the base of the membranaceous detlexed middle tooth, The lateral lobes 

 are setaceous, and, when in their normal position, strongly curved upward at 

 the tip. The calli at tho base of the labellimi are peculiar in that they are 

 linear and curved, not like papillae. The leaves in the present specimen are 

 scarcely 1 cm Long and about equal in length to the naked part of the peduncle.

0. Clemensiae appears to be a near affinity of C. veatita which is a more robusl 



species with much larger leaves and Mowers. It is also closely related to LtfWM 



confuta J. J. Smith, from which it is readily distinguished by its smaller stems 

 and leaves and by its smaller lowers. The lips of 0. veatita, Liparia confuaa, 

 and C. Olemenaiae are very similar. These species are most easily recognized by 

 the differences In their vegetative parts. It may be thai they represent forms 

 of a polymorphic species, but until more mat. ■rial lias been studied with this 

 suggestion in mind they should be regarded as distinct from one another. I have 

 seen six plants of 0. Olemenaiae.

OBERONIA l.indl. 



Oberonia aporophylla Reichb. f. Bonplandia 3 (18f). r )) 223. 



In my second list of the orchids collected in the Philippines for, the Bureau 

 of Science this speri.s was included. The material on which determination was 

 attempted consisted of fruiting specimens, since the publication of Fascicle II 

 of "Orehidaeeae" more material has come to hand in which the Sowers are in 

 excellent condition for study. The labellum. petals, and sepals agree perfectly 

 with the sketch of a Sower of 0. aporopkyUa in Lindley's herbarium at Kew, 



and the habit of the plant is like that of the material, numbered 2113, collected 

 in the Philippines by Cuming. O. aporophylla is a slender caulescent species 

 about 2 dm tall with from In io 20. triangular, acute, obliquely ascending leaves 

 which are about 2 cm long. The leafy stem terminates in a slender, rather 

 loosely flowered, spicale raceme about 1 dm long. The labellum is subpandurale. 

 emarginate, somewhat auriculate on each side at base. l.fi mm long, the terminal 

 portion is Snely toothed. The petals are linear.

I have seen a single plant of this species from Mindanao. In every detail its 



vegetative and Moral parts agree with specimens in my herbarium from Florida, 



l T . S. A., and from Cuba. Flowers from a planl collected near Miami. Florida. 

 when moistened in water and laid beside Mowers from the Philippines resembled 

 them so closely that it was quite impossible to distinguish between them by any
