 Very variable in size, pubescence, relative length of its capsules, etc. 

 Yar. angustifoliuji, Fenzl, I.e. i. 413, with cauline leaves narrowly 

 oblono" to linear, attenuate at the base, much fascicled and 9-15 lines 

 in length, and var. latifolium, Fenzl, 1. c. i. 412, with shorter oblong 

 leaves, 6-8 lines long, broad at the base, are forms strikingly different 

 in their extremes, but rather freely intergrading and often difficult to 

 distin o-uish. The latter is perhaps a little more common in the Rocky 

 Mountains but extends eastward to Labrador. Better marked are 

 the following. 



Var. oblongifolium, Hollick & Britton. Leaves oblong 

 or lance-oblong, obtuse or obtusish : capsule longer, H-2| times as 

 long as the calyx. — Bull. Torr. Club, xiv. 47, t. lxiii. G. oblon- 

 gifolium, Torr. Fl. U. S. 460; Torr. & Gray, Fl. i. 188. ? G. di- 

 chotomum, Muhl. Cat. 46. ? G. bracteatum, Raf. Prec. Decouv. 36. 



— Nova Scotia to Virginia, and Montana, Scribner, to New Mex- 

 ico, Vasey. This variety has been widely drawn by its authors to in- 

 clude narrow-leaved forms as well as the original rather broad-leaved 

 C. oblongifolium, extended series of specimens showing complete tran- 

 sitions. 



Var. maximum, Hollick & Britton, 1. c. xiv. 47. Taller, 

 1-2 feet high : leaves elongated, lanceolate, acutish, 2-3 lines bread : 

 inflorescence very spreading : capsule equalling or half exceeding the 

 calyx. — G. oblongifolium, Torr. Pacif. R. Rep. iv. 70. G. pilosum, 

 Brew. & Wats., Bot. Calif, i. 67, not of Ledeb. — Dixon, 111., 

 Vasey, and in California, Punta de los Reyes, Bigelow, and elsewhere. 

 Scarcely more than a rank growing form, but serving to connect the 

 next species through var. Fischerianum. 



Var. villosum, Hollick & Britton, 1. c. xiv. 49. Densely 

 villous: leaves rather broadly lanceolate. — G. velutinum, Raf. Med. 

 Rep. (hex. 2), v. 359. G. villosim, Muhl. Cat. 46. Darlingt. Fl.
