narrower : Mowers mostly .5 to 20 and raceuioso or spicatc, forming a loafy thyrsus 

 (rarely solitary in depauperate plants) : calyx lobes narrow and unecpial, mostly 

 linear and the longest shorti^r than the tube : corolla short-funnelform, blue (an 

 inch or more in length) ; appendages triangular, acute, mostly 2-cIeft or 2 - 4-cuspi- 

 date, shorter than the round ovate lobes : seeds ovate or ()l)Iong, flat, wing-margined. 

 Var. ovata, (5ray : a form with ovate or oblong huives, and fewer" commonly 

 larger flowers , the calyxdobes lanceolate and as long as the tube ; the lobes of the 

 corolla commonly rounder.

8. G. SCeptrum, rxrisobach. Erect, 2 to 4 feet high, leafy : leaves from ovate 

 to oblong-lamieolate (an inch or two long) : flowers several and raeomosoly or spi- 

 cately clustered, sometimes almost solitary: corolla campanulate, an incl'i and a 

 half long; its lobes bro.ad and rliombic-rounded : seeds somewhat fusiform, narrowed 

 into a cellular appendage at both ends. — Hook. Fl. ii. 57, t. 145. 



Var. humilis, Engelm. ined. Much smaller : stems slender and weaker, a foot 

 or two long, one-few-flowered: corolla an inch and a (piarter in length- the sinuses 

 sometimes 2 - 3-crenate. — (7. 3fenziesii, Grisebach, 1. c. G. afllnis, Orav in coll'

4. FRASERA, Walter. 

 Calyx deeply 4-parted, slightly imbricated in the bud. Corolla rotate, 4-parted, 

 persistent; the divisions convolute in the bud; their inner face furnished with a 

 large depressed gland or pair of glands, which arc bordered by a fringe, sometimes 

 u crown of bristles or scales at their base. Stamens inserted on the very base of 

 the corolla : filaments subulate, distinct or obscurely monadelphous at base. Ovary 

 ovate, tapering into a conspicuous and persistent style : stigma small, 2-lobed or 

 entire. Capsule coriaceous, commonly flattened, strictly one-celled, few - 30-seeded. 

 Seeds comparatively large, flat, sometimes margined. — Glabrous and commonly 

 stout herbs, or one slender species puberulent, all North American, and all but one 

 far-western; with a thick and purely bitter biennial root, an erect leafy stem, bear- 

 ing opposite or whorled leaves (which when broad are nervose, and in most species 

 cartilaginous-margined), and abundant rather large flowers in cvmose clusters ; the 

 corolla dull white, yellowish, or bluish, and commonly dark-dotted. Parts of the 

 flower sometimes in fives?
