Orthocarpus. SCROPHULARIACEiE. 577 



two high, somewhat pubescent or in the mostly dense short spikes sometimes vil- 

 lous-hirsute : leaves from narrowly lanceolate to oblong, entire or laciniate-incised 

 into rather short and blunt lobes ; the upper and the bracts more cuneate-dilated, 

 equalling the flowers, herbaceous, the blunt tips whitish ov yellowish : corolla near 

 an inch long, dull white, often purplish-tipped ; the lower lip considerably dilated. 



Tine woods and low grounds near the sea-shore, Monterey to Humboldt Co., and along the 

 coast to Washington Territory. Seeds oblong, twice or thrice larger than those of the preceding, 

 to which the species is much more nearly related than to the next. 



-f- +- Filaments pubescent : upjier lip of the corolla long and almost linear, obticse 

 and hooked at the apex, densely red-bearded; lower lip with three verij small and 

 somewhat didymous little sacs at its broad apex, directly under and not larger than 

 the short and rounded recumbent teeth or lobes : stigma very large, depressed<ain- 

 tate : cap^side ovate. 



5. O. purpurascens, Benth. Erect, at length diffusely much branched at the 

 base, rather .stout, a span to a foot high, hirsute: leaves above the lanceolate or 

 linear base laciniately once or twice pinnately parted into narrow linear or filiform 

 divisions : spike dense and thick, oblong, at length cylindrical : bracts about the 

 length of the flowers ; their laciniate-lobed divisions or their tips and those of the 

 calyx-lobes crimson-purple and rose-color: corolla about an inch long, the tube 

 yellowish or whitish, the summit crimson or red. 



Common along the liills and mountains of the coast, from Monterey to Humboldt Co., so 

 abundant as to give the ground a purple hue for miles in some places : occasionally, with duller 

 or only pallid color, in salt marshes. The reddish soft and copious beard of the narrow and 

 hooked upper lip, which marks this species, is composed of many- and close-jointed hairs. Seeds 

 oval ; the loose arillifonn coat deeply favosa. 



§ 2. Lower lip of the corolla simply saccate or nearly so, its 3 teeth very short and 

 inconspicuous or obsolete; the tipper lip moderately smaller, short, ovate-tri- 

 angular ; the tube hardly if at all surpassing the ccdyx : stigma small and 

 entire: anthers all 2-celled : seeds with a very loose costate-reticulated coat : 

 bracts all herbaceous. — True Orthocarpus. (Orthocarpus, Nutt.) 

 C. O. luteus, Nutt. A span to a foot high, with strict simple or virgately 

 branched stem, minutely pubescent and more coarsely hirsute : flowers leafy-spicate : 

 leaves linear-lanceolate, entire or 3-cleft ; the floral ones similar or often broader : 

 calyx-teeth lanceolate, acute: corolla golden yellow (half an inch long), not ex- 

 ceeding the floral leaves or bracts ; the lips of equal length and not very different 

 in size. — 0. strictus, Benth. ; Hook. Fl. ii. t. 172. 



Dry banks and plains, along the northeastern borders of the State (Carson and Lake Washoe, 

 Nevada, Anderson, Torrcy) ; thence northward and eastward to British Columbia and to the 

 Upper Mississippi. 



7. O. tenuifolius, Benth. A span or more high, somewhat hairy or glabrate : 

 flowers in a dense thick spike : leaves or at least the upper ones hispid-ciliate ; the 

 lower linear and mostly 3 - .5-cleft, with the divisions linear-filiform ; the floral or 

 bracts broadly ovate, incisely 2 - 3-cleft or toothed, or often entire, becoming thin 

 and reticulated in age, usually imbricated over the floAvers or fruit : calyx-teeth 

 subulate: corolla purplish; the upper lip becoming longer, slightly hooked at 

 the tip. — Bartsia tenuifolia, Pursh. 0. imbricatus, Watson, Bot. King Exp. 458. 



Drv ridges. Sierra Nevada, near Summit {E. L. Greene), and Lassen's Peak {Lemmon); thence 

 to 15ritish Columbia and Montana. Spikes from 1 to at length 3 or 4 inches long ; the broad 

 imbricated bracts strikingly and abruptly different from the leaves below. The Calitorman 

 siieciinens are of the smoother fonn, very nearly that described as 0. imbricatus. 



8. O. bracteosus, Benth. In foliage and aspect resembling tlie preceding, but 

 the bracts deeply 3-cleft and with triangular-lanceolate lobes (their pubescence rather 

 hirsute), shorter than the bright rose-purple corolla :_ lower lip of this ainph'r and 

 more saccate ; the upper with narrower and more decidedly hooked ti[).
