Pogonia.] CXLVIII. ORCHIDE^B. (J. D. Hooker.) 119 



broadly cordate or orbicular, strongly plicate. Flowers solitary, few, or 

 many, racemed, horizontal or pendulous. Sepals andpetals subequal, narrow, 

 ccnnivent or widely spreading. Lip inferior, adnate to the base of the 

 column, sessile or sub-clawed, usually narrow, entire or 2-fid or 3-lobed ; 

 spur a very short sac. Column elongate, tip clavate, stigma oblong or 

 broader ; rostellum short ; anther substipitate ; pollinia 2 or 4. Capsule 

 erect or pendulous. Species about 30; of Sect. Nervilia about 12. 



The above characters apply exclusively to the section Nervilia, (genus of 

 Gaudichaud), to which all the Old World species of Pogonia belong; and which all 

 flower before leafing. All the other species, except one Japanese, are New World, 

 and their flowering sterns bear leaves. The species are very difficult of analysis 

 from Herbarium specimens, but I have been greatly aided by the drawings in 

 Herb. Kew, and those of Herb. Calcutt., kindly lent by Dr. King. All want 

 revision. 



* Stem 1-%-fld. 



1. P. plicata, Lindl. Gen. & Sp. Orchid. 415 ; leaf orbicular- cord ate 

 hairy, stem 1-3-fld., lip embracing the column, tip dilated 2-lobed.

LOWEE BENGAL, the GONCAN & MYSOEE, Roxburgh, &c. 



Tuber globose. Leaf 2-4 in. diam., very many-nerved; petiole 1-3 in., often 

 rusty-purple or brown. Flowering stem 4-6 in. ; bracts small; flowers 1 in. diam. ; 

 sepals and petals widely spreading, narrowly oblanceolate, acuminate, greenish ; lip 

 embracing the column, sides convolute, whitish or rose-coloured, tip pink.- Roxburgh 

 observes and figures the tuberiforous suckers propagated from the apex of the petiole 

 under the surface of the soil. 



2. P. biflora, Wight. Ic. 7399; leaf unknown, stem 2-fld., lip 

 obovate obtusely 3-lobed about the middle, embracing the column. 



MALABAR ; in the Wynaad jungles, Jerdon. 



Tuber globose. Flowering stem 2-4 in.; bracts slender; flowers 1 in. diam.; 

 sepals and petals narrowly oblanceolate, white ; lip pink, contracted at the base, side 

 lobes rounded, midlobe emarginate crisped. Amongst Parish's drawings is one of a 

 similar Moulmein plant in flower only, with red-brown stem, pink sepals and 

 petals, and a more clavate column than in Wight's figure. 



3. P.juliana, Wall. Cat. 7399; leaf ovate-cordate glabrous, stem 

 1-fld., lip with 2 narrow falcate side lobes near the base which embrace the 

 column, and a longer rhombic-lanceolate acuminate midlobe which is hairy 

 at its base. Hoo&.f. Ic. Plant, ined. Epipactis Juliana, Roocb. Fl. Ind. iii.

Tuber globose. Leaf 2-3 in., 5-7-nerved, green or purple beneath; petiole 

 short. Flowering stem 3-6 in. ; bracts ensiform ; flower about 2| in. diam. ; sepals and 

 petals narrowly oblanceolate, acuminate, green ; side lobes of lip white, midlobe 

 spreading, white mottled with pink. Amongst Parish's drawings is one of a Moulmein 

 plant (P. cuprea, Par. mss.) \ikejuliana, but with purple-green sepals and petals, and 

 the hypochile longer than the epichile ; it is in flower only.
