1. A. sinicum, LindL in Bot. Reg. t. 659. Nearly glabrous. Roots 

 occasionally bearing tubers. Stems 1-8 ft. long, sparingly leafy. Leaves 

 linear, 8-18 by J- J in. (but see var. /3). Panicle-branches elongated, 

 slender, subracemose ; bracts J-2 in. long, linear-lanceolate, flat ; cymes 

 usually thin, loose, but sometimes the inflorescence is dense with 

 numerous flowers ; lower flowers of the cyme often sterile, early cadu- 

 cous, so that the top of the cyme-peduncle appears knotted. Sepals 

 i in. long, elliptic, obtuse, half-petaloid in texture. Petals \ in. long

 (but see var. /3). Capsule \-\ in. long, 3-valved ; seeds normally 2 in 

 ^ach cell, obscurely wrinkled. — C. B. Clarke in DC. Monogr. Phan. iii.
