Mergui, Griffith. I am indebted to the late Mr. 

 Griffith for my only specimen of this plant. It is 

 not improbable that it may not be identical with 

 Blume's plant which is from Java, but as it seems 

 to correspond with his character, I cannot oh the 

 mere ground of a geographical diflFerence venture 

 to view it as a new species. His characters are 

 generally too brief but, so far as it goes, the two 

 plants agree. It is proper to remark Siat the figure 

 of the entire plant is somewhat reduced to bring it 



buhform, conical, curved outwards: lamina of the within my contracted space, to which I may add 



lip 3-lobed ; lobes all obtuse, the middle one much 

 larger. Sepals pale yellow with a red margin, lip 

 white or slightly tinged with yellow.

The habitat of my plant is most unfortunately not 

 noted, and the specimen is not perfect enough to 

 admit of my enlarging on the points of distinction 

 between this and the Java species. The genus is 

 a very curious one. The two lateral sepals are 

 united hence the perianth, exclusive of the lip, is 



given therefore are prepared from the dried speci- 

 men and may not be found quite correct. The lip 

 is reddish-purple ; the sepals as green nearly as the 

 leaves, the scape reddish-green. It seems very 

 neary allied to Z. ztylanica^ Lind., but that has 3- 

 nerved leaves, which this certainly has not ; the lip 

 in that is tomentose within and revolute on the 

 margin, while in this, it is scarcely pilose and invo- 

 lute ; neither, so far as is shown in the drawing, is 

 it punctulate. The genus is an obscure one, and 

 I doubt whether my dissections are sufficient to 

 remove the difficulties, the more so as there is appa- 



only 4-leaved. The lip, in place of being free to rently a discrepancy between figures 2 and 3. 



the insertion, has a long furrowed claw, the edges of 

 which adhere to the column leaving a tube between. 

 The anther bed in place of presenting the usual form 

 of a simply flattened or concave surface on the end 

 of the column, on which the naked anther lies, is 

 covered by a delicate vaulted membrane or veil, 

 within which the anther nestles but is still visible, 

 through its translucent texture, in the way I have 

 endeavoured to show in the magnified figure No. 4, 

 and also in No. 2. 



1748-2, PoDOCHiLus MALABARicus (R, W.), leaves 



short, fleshy, imbricating, obtuse: spikes terminal, 

 short, few-flowered, drooping: bracts broad ovate, 

 somewhat cuspidate, shorter than the ovary: petals 

 somewhat narrower than the sepals, lanceolate : late- 

 ral sepals connate, forming a short ventricose spuri- 

 ous spur: lip entire constricted in the middle, upper 

 half linear lanceolate, obtuse. 



Malabar, on branches of trees, flowering during the 

 rainy months. I am indebted to Mr. Jerdon for the 

 opportunity of figuring this plant which is the first 

 species of the genus found in Southern India. Two 

 species, both (but especially P.falcatus) nearly alli- 

 ed, are natives of Ceylon. 



1748-3. Appendicula HASSELTri (Blume), stems 

 simple, terete : leaves broadly linear, retusely mucron- 



ulate, sheaths of the leaves edentulate : limb of the 

 lip erect, crenulate. 



1749. BoLBOPHYLLUM TREMULUM (R. W-), pSCUdo- 



bulbs ovate, somewhat corrugated, leaf ovate, lan- 

 ceolate acute: scape straight: bracts small, ovate, 

 acute: sepals ovato-lanceolate acute, pubescent: pet- 

 als rhombio-ovate small, densely ciliate : lip articu- 

 lated with the prolonged base of the column, linear, 

 obtuse, the back toward the apex, covered with long 

 tremulous hairs. Flowers yellow, passing into pur- 

 ple towards the margins of the sepals; lip purple. 



Wynaud entrees, Jerdon and Major Cotton, who 

 now has this species, with very many others, grow- 

 ing in his conservatory at Ootacamund. The specific 

 name is in allusion to the long hairs on the back of 

 the lip, which, when growing, are perpetually in a 

 state of tremulous motion however still the air. It 

 is a beautiful and curious plant, allied by the pecu- 

 liarity of its lip to B, Calamaria a Sierra Leone 

 plant. 



The figure of the whole plant is taken from a 

 coloured drawing of Mrs. Jerdon's. All the analyses 

 were prepared from a specimen preserved in spirits 

 communicated by Mr. Jerdon. The hairs of the lip 

 are jointed at the base (hence their mobility) as may 

 be seen from the linear figure in the centre of the 

 plate.
