19. 0. LiNEARiLOBUS, Beuth. Plant. Hartw. 330. Pilose-Lispid, erect, strict, 12-15' high, somewhat 

 branched above ; leaves 1-3' long, linear, the lower entire, the upper deeply 3-5-lobed ; spilsie short, 

 dense ; bracts palmately 5-cleft with linear lobes exceeding the flowers ; calyx-lobes linear, much 

 exceeding the tube, nearly equaling the corolla ; corolla 10" long, pubescent, purplish, the galea straight, 

 but little exceeding the lip.— Collected only by Hartweg (1903) in the mountains of California. The 

 single specimen in Herb. Gray, scarcely differs from 0. demiflorus except in its greater hispidness. 



20. 0. CASTiLLEioiDES, Benth. 4-8' high, diifusely branched, pilose-hispid above; leaves 1-2' long, 

 lanceolate, oblong or ovate, the upper usually coarsely short-lobed ; bracts broadly dilated, the rounded 

 apex shortly 3-5-cleft ; calyx and corolla as in 0. densiflorus into which it seems to run and of which it 

 may be a form corresponding to the variety of 0. purj>urascens. — From San Francisco to Washington Ter- 

 ritory. 



21. O. AUSTKALis, Benth. Chili and Peru. 



22. 0. PALLESCENS, Gray. Jmer. Jour. Sci. 34. 339. Proc. Amer. Acad. 7. 384. Perennial, hirsute- 

 pubescent; stems ascending, simple or branched, 4-10' high ; leaves 1-2' long, linear, divaricately few- 

 lobed or entire ; spike usually crowded, 1-3' long ; bracts colored, dilated, 3-5-lobed, the middle lobe 

 broad and rounded at the apex or variously cleft ; calyx 8" long, bifid to the middle, with the segments 

 more or less 3-cleft ; corolla 8" long, pubescent, the galea obscurely 3-lobed with the middle lobe longer 

 and acutish, a little exceeding the obtuse oblong teeth of the slightly dilated 3-plicate lip ; capsule 3-4" 

 long. — California and Oregon. Nuttall's original specimens and Lyall's from the Columbia have the 

 calyx-segments shortly 2-toothed and the galea considerably longer than the lip ; other mountain speci- 

 mens of Geyer, Brewer, Cronbhite and Torrey have a shorter galea and the calyx more deeply cleft, and 

 still others from Kellogg have the calyx equally 4-oleft. 



23. O. PILOSUS, S. Watson. Perennial (?), pilose-pubescent ; leaves lanceolate, few-lobed ; bracts 

 colored, broad, 3-lobed, the middle lobe dilated and rounded; calyx 4-lobed to the middle, cleft ante- 

 riorly nearly to the base ; corolla yellowish, galea straight, acute, exceeding the prominent teeth. See 

 page 231. 



CORDYLANTHUS. 



From the Revision of the Genus by Dr. Gray in Proc. Amer. Acad., Vol. VII, pp. 381-384, (1867,) with 

 a slight modification of the characters of the second section. 



§ 1. ADENOSTEGIA. Inflorescence compound, the flowers often on short pedicels, with 2-4-bract- 

 lets ; calyx of two leaves, the lower exterior in ajstivation ; floral leaves and bracts (except in 

 C. laxiflorus) very often truncate, retuse, or subtridentate at the apex and more or less callous- 

 tipped. 



* Lower sepal about 5-nerved, the upper subscarious, 2-nerved and bifid ; stamens 2, with nearly 

 glabrous filaments and 1-oelled aiJthers; floral leaves trifid or snbpinnatifid. 



1. C. CAPiTATUS, Nutt. Heads rather few-flowered. See page 231. 



* * Sepals 5-6-nerved, the upper one entire or emarginate ; stamens 4, with villous-filaments and 

 2-celled anthers ; leaves narrow-linear or flUform. 



(a.) Upper and floral leaves 3-5-cleft and with the branches minutely scabrous or subglandular- 

 puberulent. 



2. C. FiLiFOUUS, Nutt. Lower leaves entire, the floral ones sparingly hispid, especially on the mar- 

 gins, subcuneate at base, more or less dilated at the extremities ; flowers in crowded heads ; sepals 

 oblong, obtuse.— Middle and Southern California. 



3. C. RAMOSUS, Nutt. Leiives all divided, the filiform segments not dilated; floral leaves with 5-7 

 nearly equal lobes, scarcely thickened above ; corolla yellow, slightly exceeding the ovate or oblong 

 obtuse calyx-leaves. See page 232. 



4. C. Wrightii, Gray. Leaves 3-5-parted, filiform, the floral similar and not hispid; heads few- 

 flowered, terminal; sepals lanceolate, the upper one 2-3-toothed ; coroUa 1' long, purpUsh.-California, 

 Arizona, and New Mexico. 



(6.) Leaves nearly always all entire; flowers subpanioled. 



5. C. PiLOSUS, Gray. 2-4° high, more or less hoary with soft spreading subviscid hairs; leaves 

 linear, the upper usually truncate-emarginate or broadly 3-lobed at the apex; flowers crowded or rather 

 loose ; sepals lanceolate-oblong.- Middle California.
