580 SCROPHULARIACE^E. Orthocarpus. 



17. O. hispidus, Benth. Strict, mostly slender and little branched, hirsute: 

 leaves with few slender divisions, or the lower entire : leafy spike virgate : calyx- 

 lobes much shorter than the tube : corolla whitish or pale yellow, its sacs rather 

 narrow and longer than deep. 



Common in Oregon, as far south as Klamath Valley (Cronkhite) ; therefore probably in Cali- 

 fornia. Corolla half an inch long ; the lower lip much smaller than in the preceding. 



18. O. linearilobus, Benth. A foot high, above with hirsute or somewhat 

 hispid pubescence : leaves with few or several long and slender divisions ; floral ones 

 equalling the densely spicate flowers, the tips of their divisions commonly tinged 

 with purple : calyx-lobes much longer than the tube and equalling that of the 

 (purplish 1) corolla : sacs of the latter narrow, tapering gradually downward, much 

 longer than deep ; the ovate-subulate teeth thickish and short. PL Hartw. 350. 



Mountain pastures of the Sacramento district, Hartweg. In grain-fields, Anderson Valley, 

 Mendocino Co., Bolander. Corolla three fourths of an inch long. 



18. COKDYLANTHUS, Kutt. 



Calyx spathaceous, of an anterior and a posterior leaf-like division, or the anterior 

 one wanting. Corolla tubular, a little enlarging upward, bilabiate ; the lips short 

 and nearly of equal length ; the lower very obtusely and crenulately 3-toothed ; the 

 upper straight and compressed, with the apex more or less uncinately incurved. 

 Stamens as in Orthocarpus : cells of the anthers either ciliate, or minutely bearded 

 at base and apex. Style mostly hooked at the tip, and more or less thickened under 

 the entire terminal stigma. Capsule compressed, loculicidal. Seeds several or 

 rather numerous, with a loose coat, tipped with a point. Branching annuals ; with 

 alternate narrow leaves, either entire or 3 5-parted, the floral ones or bracts not 

 brightly colored. Flowers one to each bract, not showy, yellow or purplish, capi- 

 tately or spicately crowded, or sometimes loosely paniculate. Gray, Proc. Am. 

 Acad. vii. 381 ; Watson, Bot. King Exp. 231, 459. 



The species are all Californian and of the interior region eastward, one extending to the western 

 frontiers of Texas. The genus was first named Adenostcgia, by Bentham ; but as this name was 

 only partially applicable, the author himself adopted Nuttall's name, Cwdylanthus. 



1. Calyx 1-leaved : flowers short-pedicelled or almost sessile, subtended by 2 to 4 

 bractlets : floral leaves and bracts vtith the truncate retuse or 2 3-toothed apex 

 tipped with a callous gland. ADENOSTEGIA, Gray. 



* Stamens 2 : anthers \-celled: filaments nearly glabrous : posterior division of the 



calyx 2-nerved and 2-cleft. 



1. C. capitatllS, Nutt. A foot or two high, paniculately much branched, 

 finely soft-pubescent, rather hoary: leaves very narrowly linear, or the floral broader 

 and 3 - 5-cleft : flowers few or several in a capitate cluster at the end of the branch- 

 lets : corolla purplish, half an inch long : capsule 8-seeded. Benth. in DC. Prodr. 

 x. 597 ; Watson, 1. c. 



"California, Nuttall" ; but more probably collected by him in the interior region. Redis- 

 covered by Watson, in the Clover Mountains in the northeastern part of Nevada, not far south of 

 Nuttall's route in crossing the continent. 



* * Stamens 4 : anthers ^-celled : filaments villous : both calyx-leaves 5 - b-nerved. 



2. C. ramosus, Niitt. A span or two high, diffusely branched from the base, 

 hoary-puberuleut : leaves mostly 3 - 7-parted into filiform divisions, which are 

 hardly at all glandular or dilated at the apex : flowers few in a terminal fascicle or 

 in the upper axils : corolla yellow : capsule 20-seeded. Watson, 1. c.
