This interesting and hitherto little-known species is a native of Gosaingthan 

 and Kamaon in the Himalaya mountains, where it was gathered by Dr. Wal- 

 lich's collectors, and was first described by me in the Prodromus F/orœ 

 IVepa/ens/s. The flowers are considerably larger, and more abundant, and 

 the plant is altogether more showy than the amplex/JoHi/s, from which its 

 straight naked peduncles, blunt sepals and anthers, much longer stigmata, 

 and more numerous seeds will readily distinguish it.

This very natural genus, as I have already stated, forms the transition from 

 tlie Smilaceœ to tiie 3Ielanfhaceœ, and possesses several characters in com- 

 mon with Streptopus and Disporum. From the former genus it is essentially 

 distinguished by its much more lengthened filaments, binary pendulous ovula, 

 and terminal umbellate inflorescence, — characters in which it agrees with 

 Disporum ; but it differs from this last in its innate anthers, nearly concrete 

 styles, and pendulous seeds. 



The genus is remarkable for its forked pubescence ; the hairs are furnished 

 with one, rarely with two short branches, which are continuous with the ceils
