C. ovuLARis, y. cyl'mdricus, p. 279. No. 348 of Mr. 

 Drumn)ond's first Texan Collection scarcely differs from this 

 plant. 



C. ERYTHRORHizos, p. 280. Near St. Louis, Missouri, T. 

 Drummcnd! ; Kentucky. Dr. Short! I have specimens of 

 this plant collected near Havanna by my friend, B. D. Greene. 

 Esq. Among the plants collected by Dr. Baldwin in the 

 Southern States, is a variety of C. erythrorhizos with the umbel 

 decompound, and with the secondary rays shorter than their 

 foliaceous involucels.

 long to Brown's Lipocarpha, and one to his Hypoelyprum. 

 Vahl*, who adopted the genus from Richards' Herbarium, 

 but transcribed the name incorrectly, likewise constructed his 

 character so as to include both genera, but nearly all his 

 species belong to Lipocarpha as defined by Brown ; so that 

 I am still of the opinion that the name Hypolytrum should 

 have been retained for the present Lipocarpha, and another 

 name provided for the species now referred to Hypolytrum. 

 Indeed this view of the subject appear to have been taken by 

 the late P. de Beauvois, as appear from the Essai sur la Earn, 

 des Cyper. of Lestiboudois (1819) ; for the Beera of P. de B.
