ECHALTIUM (R. \\. Nerium Roxb.) 



Ger, Guar. Calyx 5-parted, segments acute. Corolla 

 inferior, hypocrateriform, limb 5-parted, tube crowned 

 with 5-forked scales, alternate witli the segments of the 

 limb. Stamens 5, inserted near the bottom of the tube 

 included ; anthers obl« rig pointed, slightly sagittate at the 



base. Ovary "2 lobed, 2 celled, with numerous ovules in 

 each, attached to an elevation down the centre* 1 (Roxb.) 

 style short: stigma capitate bifid. Follicles ovate, in- 

 flated ; seed numerous, compressed with a broad mem- 

 branaceous margin — albumen thin, membranous. Coty- 

 ledons round Ctrdate, radix cylindrical next the crown. 



1 his plant belongs to the suborder Enupocyuece, the 

 character is taken from Koxb. figme and description 

 which j roves the plant distinct from all the other genera 

 of the order, and shows that it does not even belong to 

 the same section with Wrightia the genus in which G. 

 Dota has doubtfully placed it. it wants the awned an- 

 thers of Nerium and the exserted ones of WrighUo^ 

 exclusive of belonging to a different section. To no 



other genus does the chaiacter of the crown permit it 

 to approach
