§ 4. Flowers as in § 3 ; hut tube of the corolla not exceeding the calyx, the throat 

 more funnelform, aiid ovules only 2 to 4: in each cell : filaments and anthers 

 short : perennials, more or less woody at base : leaves ojyposite and 3 - 1-j)arted, 

 so ap2)earing to be tvhorled. — Siphonella, Gray. 



14. Gr. Nuttallii, Gray. A span to a foot high, many-stemmed from the 

 woody su1)terranean base : divisions of the leaves narrowly linear, rigid (half to 

 three fourths of an inch long), mucronate, hispidulous-scabrous, the lower shorter 

 than the internodes : flowers in a capitate terminal cluster : calyx rigid, cylindra- 

 ceous, soon 5-parted, not scarious, the lobes lanceolate-subulate : ovules a pair in 

 each cell. — Proc. Am. Acad. viii. 267 ; Watson, Bot. King Exp. 26.5, t. 26, iig. 8. 



Eastern borders of the Sierra Nevada (near Carson City and on Silver Mountain, Anderson,

15. Gr. floribunda, Gray, 1. c. Taller, more slender and bushy, corymbose at 

 summit : divisions of the leaves acerose (half to a full inch long), and nearly 

 smooth : flowers cymose-clustered (delicate-scented), some of them rather slender-

Near the southern Iwrders of the State, Coulter, E. JF. Morse, Cleveland. Also Arizona, Palmer. 



II. All the leaves alternate (in our species) and 23almately parted, crowded on the 

 woody stems. (Seeds unaltered in water, developing neither mtidlage nor 

 spiral threads.) 



§ 5. Corolla salverform, u'ith tube 7nore or less exceeding the calyx : filaments short, 

 inserted in or belotv the throat: anthers short, included: ovules numerous in 

 each cell: seed-coat close, as in Phlox, developing neither spiral threads nor 

 mucilage ichen ivetted : ivoody based perennials or undershrubs. Phlox-like, 

 very leafy : leaves alternate, excep)t in one species, and much fascicled in the 

 axils, palmately 3 — 1 -parted ; the divisions acerose or subulate, rigid and 

 pxmgent : flowers showy, sessile, solitary or few in a cluster at the end of short 

 branches or branchlets. — • Leptodactylon, Benth. {Leptodactylon, Hook. & 

 Arn.) 



G. Watsoni, Gray, of Utah, is remarkalile for its opposite leaves, and nearly herbaceous flow- 

 ering-stems. — The following are decidedly shrubby. 



16. Gr. Californica, Benth. in DC. Two or three feet high, with spreading 

 rigid branches, villous or soft-pubescent when young : leaves widely spreading : 

 corolla rose-color or lilac ; the ample limb an inch and a half in diameter, and the 

 broadly cuneate-obovate lobes often erose on the margins : anthers liiiear-oblong, 

 included in the upper part of the tube : ovules 20 or more in each cell. — Leptodac- 

 tylon Californicum, Hook. & Arn. Bot. Beechey, 349, t. 89 ; Bot. Mag. t. 4872.
