In the tropical and warm temperate regions of the world — a weed. 



The typical C. nudiflora is a weak rambling plant with distant long-lanceolate 

 leaves and acuminate spathes. C. agraria, Kunth, is a shorter, neater plant with 

 shorter (almost ovate) shortly acute leaves, and short spathes. C. werneana, Hassk., 

 is a robust state with leaves up to 3^ in. long, and long spathes. The Lower Guinea 

 form, referred doubtfully by Rendle to C. barbata, may be a distinct species; it has 

 the mature leaves densely hairy on both surfaces, the stem nearly concealed by the 

 approximate hairy leaf-sheaths ; but it has the capsule and seeds exactly of C. nudiflora, 

 and must be closely allied to it. 



2. C. Sabatieri, 6'. B, Clarke in DC, Monoyr. Phan. iii. 140. Nearly 

 glabrous. Root fibrous. Stems decumbent, nearly concealed by the 

 leaf-sheaths. Leaves 1 by -J-J in., elliptic-oblong, scarcely acute, 

 margins wavy, whitened, subsessile ; leaf-sheaths scarious, inflated, 

 slightly hairy at the mouth. Spathes rather more than h in. long, 

 simply folded, ovate, acute, nearly sessile, i.e., the peduncle hardly 

 exserted from the leaf -sheath. Capsule and seeds as of C. nudijfom. —
