SIKKIM HIMALAYA, alt. 3-6000 ft., Herb. Griffith, J. D. H., &c. 

 Stem rather slender, climbing and rooting. Leaves 3-4 by 1-lf in., elliptic- or 

 obovate-lanceolate, obtusely caudate-acuminate, base acute, thinly coriaceous, puberu- 

 lous or glabrate beneath ; petiole ^ in. pubescent. Umbels terminal ; peduncles |- 

 in., pedicels 1 in. Sepals small, ovate, obtuse. Corolla pubescent within ; lobes ^ in. 

 long, subacnte. Coronal-processes horny, deeply grooved down the back, much ex- 

 ceeding the anthers. Follicles 4 in. long, slender, straight. Seeds in. long. 



SECT. IV. Euhoya. Corolla-lobes broader than long, spreading or re- 

 curved. Column sessile or subsessile; coronal-processes stellately spreading, 

 inner angle acute or produced into an erect or recurved simple spine. 



* Inflorescence terminal, or terminal and axillary, 

 t Leaves terete.

SUBTROPICAL HIMALAYA; Nepal, Wallich; Sikkim, alt. 3-6000 ft., J. D. H., 

 Treutler. 



.Stem pendulous, 1 ft. and more, flaccid. Leaves 1-2 by in. diam., straight, 

 midrib glabrous or hirsute ; petiole very short. Pedicels 1 in., and linear-oblong 

 calyx hirsute. Corolla ^-^ in. diam., and corona white. Follicles 2 in., slender, 

 straight, pericarp thin glabrous. Seeds in. long. The following varieties are so 

 identical in habit and inflorescence, that I cannot doubt their being conspecific. 

 Wight's character is drawn from specimens sent him by Wallich consisting of leaves 

 of one plant (linearis) and a detached flower of another, of which specimens (also 

 detached) are fastened on Wallich's sheet of linearis, and which have glabrous pedicels 

 and minute glabrous sepals ; these may belong to another species.
