C. Papaver, Gray. Sparsely hirsute or partly glabrous : stems a foot or two high, ascend-

 or lanceolate, and cauline into narrowly lanceolate or linear divisions of about equal length, 

 the larger ones 2 or 3 inches long : peduncles few, elongated, much surpassing the leaves : 

 involucel commonly of 3 linear bractlets, often a little remote from calyx, sometimes want- 

 ing : calyx about half inch long : petals sometimes inch and a half long, erose-denticulate at 

 broad summit, red-purple. — PI. Fendl. 17, & Gen. 111. t. 118, f. 5, carpel. Malva Papaver,

 some with short rounded lobes, others parted into narrow divisions or lobes ; the cauline 

 commonly with narrow linear divisions or lobes (1 to 3 inches long) ; upper ones reduced to 

 small simple bracts : peduncles subracemose, elongated and filiform : involucel always -want-

2 One of Dr. Palmer's specimens, included by Dr. Gray in var. lineariloba, has sub.^equently been 

 described by E. G. Baker, Jour. Bot. xxix. 49, as var.TESuissiMA, Palmer. It was collected in North- 

 ern Mexico east of Saltillo (not Salt-hills as stated in descr.), and represents an extreme form as to 

 dissected foliage. Var. Noa^o-MexicAna, E. G. Baker, 1. c, collected near McNees's Creek, New 

 Mexico, Fenrller, without number, a form with leaves few-lobed and lobes broadly lanceolate and acute 

 represents the other extreme. More ample material of these different forms may well show specific 

 differences.
