4. C. Fremontii, Watson. Erect, slender, more or less mealy : leaves 

 broadly triangular-hastate, truncate or cuueate at base : flowers often small, 

 white-mealy, scattered in small clusters upon the slender open-panicled branchlets, 

 or sometimes more contracted. — Bot. King Exped. 287. New Mexico and 

 Colorado, and westward to S. California. 



Yar. incanum, Watson. Densely farinose, low and ixither stout : flowers 

 crowded in close contracted panicles. — Proc. Am. Acad. ix. 94. Colorado and 

 New Mexico. 



5. C. leptophyllum, Xutt. Densely mealy or often nearly glabrous : 

 leaves linear, entire : fowers in small dense clusters in dense or interrupted spike- 

 lets. — From the Sierras to the Dakotas and New Mexico ; also along the 

 Atlantic sea-coast. 



Var. SUbglabrum, Watson. Nearly glabrous, loosely branched and 

 panicled, the clusters few-flowered and scattered on the branchlets. — Proc. Am. 

 Acad. ix. 95. Sandhills of the Platte. 



Var. oblongifolium, Watson. Pather stout, densely mealy : leaves 

 oblong, often slightly hastate: flowers in dense clusters in short close spikes. — 

 Loc. cit. Colorado and New Mexico. 



§ 2. More or less gland ular-puberulent, aromatic, not mealy : seed very small, not 

 exceeding the dry perianth, horizontal. 



6. C. COrnutum, Benth. & Hook. Diffusely branched : leaves thin, 

 lanceolate, repaud-dentate or coarsely sinuate-pinnatifid : flowers minute and 

 solitary, axillary and terminal upon the repeatedly dichotomous nearly naked 

 branches : calyx resinous-dotted. — Teloxys cornuta, Torr. From S. E. Cali- 

 fornia to Arizona, Colorado, and Northern Mexico. 



§ 3. Glabrous : calyx becoming more or less fleshy in fruit and often colored : 

 seed subglobose, mostly vertical : flowers in crowded clusters, axillary or in 

 spikes. 



7. C. rubrum, L. Stout, erect, branching : leaves triangxdar-hastate to 

 lanceolate, cuneate at base, sparingly sinuate-dentate, the upper narrowly lanceo- 

 late and entire : flower-clusters densely spicate upon the leafy branchlets : sepals 

 2 to 5, rather fleshy: stamens 1 or 2, or 5 in the terminal flowers. — Blitum

 New ISIexico northward, westward to California, and eastward. 



Var. humile, Watson. Smaller, prostrate or ascending : leaves ovate to 

 lanceolate, often hastate, much smaller (an inch long or less), rarely toothed: 

 flowers in axillary or somewhat spicate clusters. — Bot. Calif, ii. 48. Colo- 

 rado to Nevada and Washington. 



8. C. eapitatum, Watson. Similar, but with leaves more broadly trian- 

 gular, often somewhat hastate, more acutely sinuate-toothed : flower-clusters large, 

 in interrupted terminal naked spikes and solitary in the axils of the upper leaves: 

 calyx becoming fleshy in fruit, and the clusters red and berry-like. — Bot.
