582 G. King & R. Pantling — Neic Lido-Malayan Orchids. [No. 3, 



bract about as long as the ovary, lanceolate, erose-serrate. Sepals 

 elliptic-oblong, sub-acute, entire, revolute. Petals lanceolate, coarsely 

 seriate, spreading, the apices slightly incurved. Lip longer than the 

 petals, ovate-elliptic, not lobed, the base rounded and entire, the sides 

 with one or two irregular teeth ; the apex deeply bifid, the lobules irre- 

 gularly and coarsely toothed. 



Perak; Scortechini No. 1525. 



A species closely allied to 0. Prainiana, King and Pantling, which 

 was collected by Scortechini in Perak, but which has also been found 

 at the base of the Sikkim-Himalaya. The lip of 0. Prainiana, K. and P., 

 differs from the lip of this in not being bifid, and in being irregularly 

 lobulate-erose from base to apex ; the petals also are longer. Named in 

 honour of its discoverer, the late Father Bertold Scortechini. 



Microstylis Andamanica, n. spec. Stem about 2*5 in. long, covered 

 by 2 or 3 loose sheaths with acute apices. Leaves three or four, mem- 

 branous and plicate, broadly ovate-lanceolate, oblique, acute or shortly 

 acuminate, rather abruptly and obliquely narrowed at the base to the 

 sheathing petiole; length 3 to 5 in., breadth 1*5 to 2 in., petiole about 1 

 in. long. Inflorescence about twice as long as the leaves ; the peduncle 

 ribbed, ebracteolate ; the raceme rather laxly-flowered ; the floral bract 

 lanceolate, acuminate, shorter than the slender stalked ovary, reflexed. 

 Flowers dull purple, *4 in. long. Dorsal sepal lanceolate, obtuse ; the 

 laterals oblong, obliquely acuminate. Petals linear, blunt, shorter than 

 the dorsal sepal. Lip flat, ovate, tapering to each end ; the apex pointed, 

 entire ; the base with two rather short falcate acute converging lateral 

 lobes, their tips often touching or overlapping. 



South Andaman Island; King's Collectors. 



The nearest ally of this is no doubt M. WalUchii, Lindl., to 

 which species Sir Joseph Hooker tentatively refers it as a form 

 (Ann. Bot. Gard. Calcutta, Vol. V, Pt..l, t. 2, fig. E, and Fl. Br. Ind. V, 

 686). Sir Joseph however expresses the belief that it will turn out to 

 be a distinct species. Ample materials recently received from the 

 Andamans show that thi3 is really the case. The flowers are larger 

 than those of M. WalUchii ; they are uniformly of a dull purple colour, 

 the apex of the lip being entire and acute, and the basal auricles falcate 

 acute and converging, while both sepals and petals have recurved 

 margins. In M. WalUchii, on the other hand, the apex of the lip is 

 blunt and notched ; the basal auricles are lanceolate, their inner edges 

 straight and parallel, and their apices not converging. 



Ltparis Prazeri, n. spec. Terrestrial ; pseudo-bulb narrowly ovoid, 

 pointed, about one inch long, enveloped by one or two loose scarious 

 sheaths, and bearing near its apex two sub-opposite leaves. Leaves
