Cordylanthus. SCROPHULARIACE.E. 303 



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. 

 Seeds comparatively few and large, often apiculate or appeudiculate at one or 

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

 Acad. vii. 381, & Bot. Calif, i. 580; Watson, Bot. King, 450. Adenostegia, 

 Benth. in Lindl. Nat. Syst. ed. 2, 445, & in DC. Prodr. x. 5o7, but the name 

 abandoned iu the same volume for the more appropriate one of Nuttall. 



1. ANISOCITEI'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-clet't : flowers approximate or 

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

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

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

 Acad. 1. c. 383. Hills and ravines, Arizona, Tlturbcr, Palmer, Rutlinxk. The habitat " Salt 

 Lake, Utah, Fremont," needs confirmation. 



2. ADENOSTKGIA, Gray, 1. 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 exsertcd and conspicuous, fully inch long: stamens 4: anthers 2-celled : seeds 

 coarsely favose. 



C. "Wriglltii, 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, f 20, & Proc. Am. Acad. 1. c. S. W. borders 

 of Texas to N. Arizona, Wright, Rothrock. 



* * Corolla almost included, half to three-fourths inch long. (Natives of California and adjacent 

 districts.) 



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

 terior entire or emarginate. 



H- Seeds rather numerous, about 20, delicately favose. 



C. ramosus, Nutt. 1. c. A span or two high, diffusely much branched, cincreous-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 half inch long. Watson, 1. c. ; Gray, 1. c. Dry interior region of Oregon and W. 

 Nevada, to Wyoming. 



-H- -H- Seeds fewer and larger, mostly apiculate or appemliculate at one end; the coat close, 

 minutely and closely lincolate with sinuous linos or reticulations, or at maturity smooth and even 

 through their obliteration : callous gland generallv apparent at the tip of some of the upper leaves 

 or bracts. 



C. filifolius, Nutt. Tall, 1 to 3 feet high, loosely branched above, ronghish-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 riyida, Benth. in Lindl. 

 Nat. 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.
