end. (Greek cordulc, club, and anthos, flower, in reference to the shape of the 

 corolla.) 



Calyx diphyllous (i". c, with upper and lower leaf-like divisions); stamens 4, filaments 



villous; bracts and floral leaves gland-tipped. — Subgenus Adenostegia. 



Flowers crowded into terminal heads; bracts hirsute-ciliate 1. C. rigidus. 



Flowers 2 or 3 together at the ends of the branchlets, or only one. 



Herbage pubescent 2. C. pilosus. 



Herbage glabrous 3. C. pringlci. 



Calyx monophyllous (i. e., with a single upper leaf-like division); filaments glabrous; 



bracts and floral leaves not gland-tipped. — Subgenus Hemistegia. 



Leaves entire; stamens 4 4. C. mariti»ius. 



Some of the leaves pinnatifid; stamens 2 5. C. mollis. 



1. C. rigidus Jepson, n. comb. Erect, paniculately branched, 1 to 2 

 or 3 ft. high; herbage finely puberulent, the 3-parted bracts hispicl-ciliate; 

 lower leaves entire, upper 3 to 5-parted into linear divisions, their tips dilated 

 and retuse; flowers crowded in terminal heads; corolla yellowish and purplish, 

 over l 1 - in. long. — (Adenostegia rigida Benth. ('. filifolius Nutt.) 



Throughout Southern California and north into the southern Sierra Nevada, 

 in the Coast Ranges reaching the Santa Cruz and Mt. Hamilton ranges. 



2. C. pilosus Gray. Paniculately branched, 2 to 3 ft. high, glandular, 

 Boft-pubescent; leaves narrowly linear, entire, somewhat fascicled below, % 

 to y% in. long, the upper and floral with 1 to 3 callous-glandular teeth at the 

 dilated tip; flowers 2 or 3 together at the end of the branchlets, or only 1; 

 calyx-lobes exceeding the corolla; corolla % in. long, dull white or yellowish; 

 lower lip rather broad below, scarcely shorter than the upper; stamens 4; 

 anthers 2-celled; filaments villous. — (Adenostegia pilosa Greene.) 



Very common on dry hills throughout northern California: Los Gatos; Mor- 

 aga Valley j San Eafael; Xapa A'alley; Yaca Alts, and northward. Sept. 



3. C. pringlei Gray. Diffusely and subdivaricately branched, the branches 

 slender and very wiry, about l 1 /^ ft. high; glabrous below, the inflorescence 



- ly sprinkled with minute glandular-hispid hairs; leaves filiform, 6 lines 

 long, the floral somewhat callous-tipped; flowers few, solitary, terminating the 

 stem and branches ; upper calyx-division narrow, bifid ; corolla 5 to 6 lines long, 

 white or greenish white, marked with purple at the middle; capsule oblique 

 at summit, with a very distinct beak. — (Adenostegia pringlei Greene.) 



Higher summits and very local: Mt. St. Helena; Lake Co. The plant in an- 

 thesis is almost or quite leafless and the rigid wiry branches of a deep brown or 

 mahogany color are quite characteristic. This and the preceding species belong 

 to the subgenus Adenostegia, characterized by a diphyllous calyx; it is to be 

 noted, however, that the lower sepal in C. pringlei and C. pilosus is deciduous, 

 and that only the upper sepal persists in extreme age! The next two species 

 are of the subgenus Hemistegia, the calyx of which is monophyllous, only the 

 upper sepal being present. 



4. C. maritimus Nutt. Corymbosely branched, 5 to 12 in. high; herbage 

 glaucous and more or less hoary-pubescent; leaves linear to oblong, 1 in. long, 

 entire; flowers in short rather thick spikes, about as long as the loosely imbri- 

 cated bracts; corolla purplish; stamens 4, in very unequal pairs; anthers of 

 the longer pair 2-celled, of tike shorter pair with only the lower smaller cell; 

 filaments glabrous. — (Adenostegia maritima Greene.) 



Salt marshes near the coasl from San Francisco Bay southward to Southern 

 California. July. 



5. C. mollis Gray, simple or branched, r -j to 1 ft. high, villous-pubescent, 

 the bracts densely villous-hirsute; leaves linear or oblong, entire, or the upper
