A native of China, and from thence introduced by Captain 

 J. Garnault, into the Botanic garden near Calcutta in 1799 ; 

 where it thrives luxuriantly in the common soil of the gar- 

 den, and blossoms in March, April, and May, but more or 

 less all the year. 



Root perennial, horizontal, somewhat woolly, crooked, 

 pale-coloured, stoloniferous, fragrant, enveloped while young* 

 in short* alternate sheaths; when old marked with their ci- 

 catrices; and furnished with many fleshy ramous fibres. 

 Stems oblique, smooth, from two to lour feet high. Leaves 

 alternate, bifarious, short-petioled on their sheaths, narrow 

 lanceolar, fine-pointed, entire, smooth on both sides; length 

 frequently twelve inches, and the breadth from one to two. 

 Sheaths of the leaves stem-clasping, smooth, with a stipulary 

 process projecting- above the insertion of the leaf. Racemes 

 terminal, solitary, erect, compound. Flowers numerous, 

 large, generally in pairs or more, but expanding at different 

 periods. Bract es solitary, boat-shaped, white, one-flowered. 

 Perianth superior, three-toothed, white, smooth. Corol with

 two posterior angles, and embrace the base of the filament. 

 Filament single, opposite to the lip of the corol, projecting, 

 &c. as in the genus. Germ spherical, hairy, three-celled, with 

 many ovula in each, attached to the inner angle of the cells. 

 St'nj ma funnel-shaped, ciliate. ' Nectarial scales nearly four-
