« *» Styles 3 or 4, very long, distinct and spreading, stigmas capitate: 

 capsule ovate, strictly one-celled, a line or two long ; seeds minutely striate and 

 pitted : simple or branching herbs, 1 to 3 feet high, with small distant ascend-

This species is exceedingly variable iu the size of its leaves, but this is a 

 characteristic of the whole genus, and has led to much confusion in attempt- 

 ing to construct species upon leaf characters. The broader-leaved, more nortli- 

 ern forms are to be referred to the species, while associated with it at the south 

 is 



Var. acutifoliuiii. Usually taller and more branching: leaves 

 linear-lanceolate, tapering to a very acute apex, an inch or more 

 long, a line or two wide.

18. H. pilosum Walter. Scabrous tomentose, mostly sim- 

 ple : leaves ovate-lanceolate, usually appresscd, 4 to 6 lines long, 

 about a line or two wide, sometimes much reduced : flowers 3 to 

 5 lines in diamater, iu few-flowered cymes: sepals ovate-lanceo- 

 late, acute: petals more than twice as long, involute when old. —
