ORCHIDACE.E 



orientes, albi et purpurei, circiter 5 mm. longi, submembranacei. 

 Bracteas scariosae. Inflorescentia ad summum pseudobulbum 

 orta. Sepala lateralia triangulari-lanceolata, acuta, 5 mm. longa, 

 2 mm. lata, mentum brevem, 1 mm. longum formantia. Sepalum 

 dorsale oblongi-lanceolatum, 5 mm. longum, vix 2 mm. latum. 

 Petala lineari-lanceolata, valde acuta, uninervia. Labellum sub- 

 integerrimum, margine valde involutum, praesertim ad apicem, 

 prope basim lobulis auriculiformibus minutis. Totum labellum 

 circiter 5 mm. longum, 2.5 mm. latum, circuitu quadrato-orbicu- 

 lare. In disco prope pedem gynostemii callus antice et postice 

 retusus stat. Callus membranaceus 1.25 mm. latus, ad angulos 

 posteriores in lobulos laterales decurrens. Gynostemium antice 

 ad apicem in stelidia 2, bidentata producta; dens anterior quam 

 posterior muto longior. 



The type consists of a single plant. The habit suggests the 

 groups to which JDendrobium angustifolium, D. pseudoconvexum, 

 and JD. Eurorum belong. The flowers are much smaller than in 

 D. pseudoconvexum, and are well characterized by the callus on 

 the labellum, which is flat, spool-shaped, and tinged with purple 

 on the lateral ends. There are no longitudinally placed carinas as 

 in D. pseudoconvexum. The column is provided with two subu- 

 late stelidia, one on each side at the summit in front. On the pos- 

 terior side, at the base, each stelidium is unidentate. The stelidia 

 even in dried specimens are of a deep magenta purple color. The 

 nearest affinity of this species is D. parietiforme J. J. Smith, from 

 which it differs in the absence of lobes at the tip of the labellum. 

 The labellum of D. parietiforme is fleshier and between the ter- 

 minal rounded lobules distinctly apiculate in the specimen I have 

 examined.
