have rendered Botany any service by changing the place 

 of C. Zeylanicum and lattfoHum. 



Root a spherical, tunicated bulb, often two feet in cir- 

 cumference and rather more flattened at the base, than 

 on the opposite end. In C. Zeylanicum it is ovate, never 

 so large and abounds more in cobweb-like fibres. Leaves 

 numerous, radical, disposed equally on all sides, lanceo- 

 late, waved, smooth, tapering slowly from within a few 

 inches of the base to rather a broad and obtuse point ; 

 margins scabrous, with minute, cartilaginous deniiculi, 

 length from one to three feet, and from three to five in- 

 ches broad ; in Zeylanicum, they are much narrower, the 

 rib much more prominent, the length as much as three feet, 

 the margins much more waved, and perfectly smooth; this 

 mark alone is sufficient to distinguish the two plants. 

 Scapes from the axills of the decayed leaves, somewhat 

 compressed, as thick as a man's tliumb and from twelve 

 to twenty-four inches long ; in Zeylanicum it ishmger, and 

 coloured. Umbels with from ten to twenty flow ers ; in Zey- 

 lanicum rarely so many ; spathes (in both) two, of an ovate, 

 conic form, with many soft filaments mixed amongst the 

 flowers. Flowers sessile, large, tube green ; border very 

 pale rose, almost white, faintly fragrant, particularly when 

 theyfirst expand soon after sunset. In Zeylanicum they 

 are scarcely so large, and the colours are much more bright, 

 almost like Amaryllis vittata. Corol ; tube declinate, cy- 

 lindric,obscurely three-sided, about four inches long. Bor- 

 der campanulate, horizontal ; segments lanceolar, w ith ra- 

 ther soft, subulate points ; length between three and 

 four inches. Filaments six, shorter than the segments of 

 the border of the corol, inserted on the mouth of the tube, 

 declinate, with apices sharp, and always erect. Anthers 

 falcate, incumbent and tremulous, pale yellowish grey. 

 In Zeylanicum they are brown. Germ inferior, oblong, 

 three-celled, with several ovula in each, attached in two 

 vertical rows, to the two lobes of the thick fleshy recep-
