 erect, !'_• to 2 ft. high, often much branched; herbage minutely rough-puberu- 

 lenl 01 almost glabrous; leaves oblong-ovate or lanceolate, sessile, 1 in. long 

 or less, sharply serrate; flowers mostly in clusters on short pedicels; clusters 

 axillary, or the upper leaves reduced and the inflorescence racemose; corolla 

 cylindrical in the bud, 4 or 5 lines long, 2 or 3 times the length of the subulate

 turbinate.

 Placer Co. to Mt. Shasta. July. 



3. C. scouleri Hook. Stem slender, erect, or decumbent at base, mostly 

 Bimple, 6 to 12 in. high; herbage glabrous; leaves ovate to lanceolate, sharply 

 serrate, : ;4 to l 1 /^ in. long, tapering at base into a margined petiole; flowers 

 on filiform peduncles, solitary in the axils or terminal, or the upper leaves 

 reduced to minute bracts and the inflorescence paniculate; corolla exceeding 

 or twice as long as the subulate calyx-lobes, deeply cleft into ovate-oblong 



ldl.es. 



Redwood region from Marin Co. northward to Washington. 



4. C. exigua Rattan. Branching from the base and diffuse, 2 to 4 (or 

 6) in. high, short-hispid, especially at base; leaves obovate, linear, or the up- 

 permost subulate; flowers erect, lateral or terminal on the branchlets, of two 

 kinds, one with slender and rather short style having 3 revolute stigmas at 

 apex and with the dilated bases of the filaments not ciliolate; the other kind 

 with the style longer, conspicuously club-shaped and merely notched at apex, 

 the dilated bases of the filaments ciliolate; corolla of both kinds light blue, 

 2 to 4 lines long; calyx-lobes subulate-linear, nearly twice the length of the 

 turbinate tube; capsule somewhat urn-shaped, with 3 valve-like openings just 

 above the middle. 



Coast Range peaks and ridges: Mt. Hamilton; Mt. Diablo; Mt. Tamalpais; 

 Mt. St. Helena. 



2. SPECULARIA Heister. Venus Looking-glass. 



Annuals with leafy erect stems. Flowers solitary or in pairs, in the axils 

 of the Leaves, blue or purplish, 1 or 2-bracteolate. Our species with two kinds 

 of flowers: the earlier fertilized in the bud, with undeveloped corolla and 3 or 

 4 calyx-lobes; the later with a conspicuous blue corolla and 5-lobed calyx. 

 Corolla rotate or nearly so. Stigmas and cells of the ovary 3, sometimes 

 2 or 4. Capsule rather long, prismatic or cylindric, dehiscent by small valve- 

 like openings on the sides. (Latin speculum, a looking-glass.) 



1. S. biflora (R. & P.) Gray. Stems slender, simple or with many 

 branches from the base, 8 to 15 in. high, retrorsely scabrous liispidulous on the 

 angles; Lnternodes rather short; leaves ovate, mucronate, sessile, entire, or 

 somewhat crenate, 3 to 6 (or the lowermosl 8 or !») lines loner; corolla blue, 

 exceeding the Linear-lanceolate calyx-lobes; capsule 3 or 4 lines long, sessile. 



Low open hills of the Coast Ranges or fields of the interior valleys. Apr.- 

 May. 



3. HETEROCODON Nutt. 



Delicate annual with solitary axillary flowers of two kinds as iii Specularia. 



Calyx-lobes Of the earlier flowers 3 01 1. Of the later 5 (when 1 or 5 one or 

 two smaller), all foliaceous and much longer than the obpyramidal tube.
