580 SCROPHULARIACE^. Orthocarpus. 



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

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

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

 narrow and longer than deep. 



Common in Oregon, as far south as Klamatli Yalley {CronJcliitc) ; therefore protably in Cali- 

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



1 8. O. linearilobus, Benth. A foot high, above Avitli 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 V) coroDa : sacs of the latter narrow, tapering gradually do\\'nward, much 

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



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

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



18. COBDYLANTHUS, Nutt. 



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 Adcnostcgia, by Bentham ; but as this name was 

 only pai-tially applicable, the author himself adopted Nuttall's name, Cardijlantlius. 



§ 1. Cali/x 2-leaved: flowers short-pedicelled or almost sessile, subtended hy 2 to i 

 hractlets : floral leaves and bracts tmth the truncate retuse or 2- Z-toothed apex 

 tipped with a callotis gland. — Adenostegia, Gray. 



% Stamens 2 : anthers '[-celled: filaments nearb/ glahroiis : jMsferior division of the 

 calyx 2-nerved and 2-cleft. 



1. C. capitatUS, Ts'utt. A foot or two high, paniculately much branched, 

 finely soft-pubescent, rather hoary: leaves very narroAvly 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, NufiaU" ; but more probably collected by him in the interior region. Eedis- 

 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 2-ceUed : filaments villous : both calyx-leaves 5 - Q-nerved. 



2. C. ramosus, Nutt. A span or tw-o high, diftusely branched from the base, 

 hoary-puberulent : 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.
