flowers in small terminal heads or clusters, or more scattered along the branches ; 

 the bracts and calyx not colored, and corolla seldom much surpassing the calyx!

 both ends. Fl. summer. — Benth. in DC. Prodr. x. 597 ; Gray, Proc. Am.

§ 1. Anisochei'la. Calyx diphyllous : corolla cleft to the middle; the lower 

 lip only half the length of the upper, entire, hardly saccate : stamens 4, with 

 one-celled anthers (and rarely a vestige of the lower cell) : both divisions of the 

 calyx 6-nerved : no gland at tip of leaves : corolla " bright yellow." 



C. laxiflorus, Gray. A foot or two high, much branched, very hirsute, above some- 

 what viscid : leaves short, linear, entire, or the uppermost 3-cleft : flowers approximate or 

 scattered on the leafy branchlets (8 lines long), either sessile and ebracteolate or short- 

 peduncled and 1-2-bracteolate : corolla little longer than the calyx: filaments villous 

 below: seeds coarsely favose, not appendaged. — Bot. Mex. Bound. 120, & Proc. Am. 

 Acad. 1. c. 383. — Hills and ravines, Arizona, Thurher, Palmer, Rothrock. The habitat " Salt 

 Lake, Utah, Fremont," needs confirmation. 



§ 2. Adenostegia, Gray, I. c. Calyx diphyllous : corolla 2-lipped at summit ; 

 lower lip about equalling the upper, 3-crenate : flowers short-peduncled or sub- 

 sessile, 2-4-bracteolate : upper leaves and bracts commonly with a depressed gland 

 or callosity at the truncate or retuse apex : corolla greenish-yellow or purplish. — 

 Adenostegia, Benth. in DC. Prodr. x. 537. 



* Corolla more exserted and conspicuous, fully inch long: stamens 4: anthers 2-celled : seeds 

 coarsely favose. 



C. 'Wrightii, Gray. A foot or two high, loosely branched, almost glabrous, or above 

 puberulent-scabrous : leaves setaceous-filiform, 3-5-parted ; floral similar, the tips not 

 dilated : flowers several in the mostly dense terminal heads : corolla purplish, with rather 

 long lips : anthers villous. — Bot. Mex. Bound. 120, & Proc. Am. Acad. 1. c. — S. W. borders 

 of Texas to N. Arizona, Wright, Rothrock.

+-■ Stamens 4: anthers 2-celled: filaments villous: both divisions of calyx 5-6-nerved ; the pos- 

 terior eutn-e or emarginate. 



++ Seeds rather numerous, about 20, delicately favose. 



C. ramosus, Nutt. l. c. A span or two high, diffusely much branched, cinereous-puber- 

 ulent: leaves filiform, all but the lower usually 3-7-parted ; no distinct apical gland or 

 dilatation : flowers few in the small terminal heads or upper axils : corolla dull yellow, 



, barely lialf inch long. — Watson, 1. c. ; Gray, 1. c. — Dry interior region of Oregon and W. 

 Nevada, to Wyoming. 



++ ++ Seeds fewer and larger, mostly apiculate or appendiculate at one end; the coat close, 

 minutely and closely hneolate with sinuous lines or reticulations, or at maturitv smooth and even 

 through their obhteration : callous gland generally apparent at the tip of some of the upper leaves 

 or bracts. <=.;■. t-i 



0. filifolius, Nutt. Tall, 1 to 3 feet high, loosely branched above, roughish-puberulent 

 and somewhat viscid or nearly glabrous below, commonly more or less hispid above, 

 especially the margins of the floral leaves : leaves 3-5-parted or some of the lower entire ; 

 the divisions from filiform to linear; those of the upper and the more dilated bracts usually 

 broadening upward and with retuse tip : heads rather many-flowered, often proliferous : 

 corolla purplish, over half inch long. — Benth. 1. c. Adenostegia rigida, Benth. in Lindl. 

 JNat. Syst. & DC. 1. c. 537. (Name replaced in the same volume by the then unpublished 

 one of Nuttall.) — Dry and moist banks, throughout all but perhaps the northern part of 

 California. Varies greatly in foliage, pubescence, &c., but generally well marked by the 

 hispid- or setose-ciliate bracts and floral leaves.
