Stem erect, leaves strap-shaped, oblique and deep- 1758-2. Pogonia biflora (R. W.), leaf 

 ly emarginate at the apex: peduncles many times scape about 2-flowered: sepals and petals lanceo- 



longer than the leaves, branched, each branch ending 

 in a short raceme of rather large yellowish flowers, 

 streaked with red ; lip deep purple. 



1756. T^NiopHTLLUM Jerdonianum (R, W.), caul- 

 escent leaves linear: spikes ramous, many-flowered: 

 bracts ovate, acute, exceeding the pedicel: sepals 

 broad ovate : petals narrow, linear-lanceolate : spur 

 large saccate, lip undulate: poUinia 4, attached to 

 a large elongated gland. 



Malabar, Jerdon. On branches of trees. Since 

 naming this plant, further consideration has led me 

 to doubt the propriety of placing it in this genus, 

 but as it seems to approach nearer to it than to any 

 other I must leave it here for the present until I 

 am enabled by the acquisition of additional speci- 

 mens to re-examine it, most of the flowers of the one 

 I had having fallen offer been injured by insects. 



1757. Cryptochilus sanguinea (Wallich). 

 ^ I am indebted to the late JMr. Griffith for the spe- 

 cimen here represented. He gathered it on the 

 Khassia Mountains. It is so very inferior to the 

 one figured by Dr, Wallich in his Tentamen Nepau- 

 lense that I should not have thought of introducing 

 it but for my wish to present analyses of as many 

 genera as I could get of this difficult and interest- 

 ing family. It may perhaps, however, be a new 

 species, a point I am unable from my materials to 



determine- 



Apetalon (R. W.). 



Gen. Char. Perianth bilabiate. Posterior sepal 

 large, 3-lobed, lobes very obtuse ; middle one larger 

 somewhat obovato-orbicular; anterior ones resting 

 on the lip, cohering nearly half their length, the two 

 forming a single sub-orbicular cleft sepal. Petals 

 none. Lip shorter than the sepals, broad, truncated 

 at the apex, disk fleshy and punctuate, margins peta- 

 loid. Column erect, clavate, anther terminal, 2-cell- 

 ed, cells slightly diverging. Pollen granular. A 

 small terestrial leafless ? plant, scape erect furnished 

 with a few scales and bearing three or four globose 

 apparently unexpanding flowers on the apex: bracts 

 ovate, large in proportion to the plant. 



In this curious plant the petals seem to combine 

 with the posterior sepal forming one of unusually 

 large size. If this is the correct view of its struc- 

 ture it follows that all the parts usually found in the 

 flower of an orchid are present in this one, but modi- 

 fied in their form and combination. 



1758-1. Apetalon minutum (R. W.). 

 Near Sultan's Battery in Coorg, under a clump of 

 Bamboos. Jerdon. 



Whole plant about 3 inches in height of a pale 

 reen or whitish colour throwing out from the scaly 

 ase several long roots. The ovary is not twisted 

 hence the flower is resupinate, though, for the con- 

 venience of bringing the parts better into view they 

 are otherwise represented in the magnified figure, 

 and for the same reason I have designated the large 

 3-lobed sepal /?o5/crior and viewed the lip as ante- 

 rior, such being the usual position in the family. 



I am indebted to Mr. Jerdon for my specimens of 

 this interesting little plant. 



late: lip obovato-rhomboid, obsoletely 3-lobed, glab- 

 rous; lateral lobes short, obtuse, middle one large, 

 undulate, slighty retuse at the apex. Lip pale pink^ 

 deeper towards the apex, sepals and petals white. 



Wynaud. Jerdon. 



This species seems nearly allied to P. Juliana but, 

 so far as I can learn from Roxburgh's full descrip- 

 tion, is quite distinct. 



Podanthera (R. W.). 



Gen. Char. Sepals and petals equal, narrow lan- 

 ceolate. Lip calcarate sessile, ovato-elliptic acute, 



3-crested on the disk, eroso-dentate towards the 



apex. Spur short clavate. Column short truncated 

 in front; posteriorly the thick fleshy filament is pro- 

 duced into an arched crest-like foot to the anther. 

 Anther 2-celled, pollinia granular, with a longish 

 slender caudicula. Herbaceous, leafless, apparently 

 parasitic, colourless plants, growing in dark forest 

 among decayed vegetable matter. "Its whole aspect 

 was fungoid-like, and of the same dead white colour, 

 except a few faint spots of pink." Jerdon. 



1759. Podanthera pallida (R. W.). 

 Wynaud, in dense forests in black vegetable soil, 



Jerdon, to whom I am indebted for my specimens 

 of this unique plant 



Scape from ]2 to 15 inches in length, many-flow- 

 ered, clothed with short sheathing scales : bracts 

 lanceolate about the length of the pedicels: sepals 

 and petals linear, lanceolate, acute, lip large, marked 

 with a few pale pink spots. Capsule ovate shorter 

 or nearly the length of the sepals, placentiferous car- 

 pels bearing a placenta on each margin and dehis- 

 cing septicidally. Nearly every capsule on my spe- 

 cimens seems to be in a diseased or monstrous state 

 as shown in figures 10 and 11, the carpels of which 

 have not united, each showing the two lines of 

 abortive placentae on the margins. 



1760. Cepripidium purpuratum (Lind.), stemless 

 leaves coriaceous, oblong, acute, striated, spotted, 

 channeled: scape pubescent: dorsal sepal acu- 

 minate, ciliate, revolute on the margin: petals ob- 

 long somewhat undulated, pubescent sterile stamen 

 lunate. 



Malacca. Griffith. 



If this plant is correctly named it will tend to 

 remove Dr. Lindley's doubts as to its being a native 

 of the Malay Archipelago. It seems to correspond 



with his character so far as can be made out irom a 

 dried specimen. 



CULLENIA. 



Gen. Char. Involucrum gamophyllous, tubular, 

 three-toothed, deciduous. Calyx gamosepalous 5- 

 toothed, corolla none. Stamens numerous ; filaments 

 long exserted, united into a tube at the base, penta- 

 delphous above; anthers minute, 1-celled, echinate, 

 *^gg^^g^ted, forming numerous capitulae on the ex- 

 serted portion of the filaments. Ovary 5-celled with 

 2 or 3 superposed ovules in each ; style equaling the 

 stamens, woolly; stigma capitate. Fruit capsular, 

 globose, echinate, 5-valved, 5-celled. Seed one or 

 two in each cell, ovoid furnished with an aril ; testa 

 fleshy; albumen none; cotyledons fleshy, unequal ; 

 radicle inferior.
