460 SCROPHULARIACEAE (FIGWORT FAMILY) 



14. Castilleja rhexifolia Rydb. Mem. N. Y. Bot. Card. 1: 356. 1900. 

 Perennial, with a woody caudex, 3-5 dm. high, glabrous below, more or less 

 villous above: leaves linear-lanceolate to ovate, 3-5-nerved, about 5 cm. long, 

 the upper often 3-5-cleft, but not deeply so, with lanceolate lobes: bracts 

 scarlet or red: calyx about 2.5 cm. long, green at the base, otherwise 

 cpccineous or scarlet, about equally cleft above and below, the clefts on the 

 sides about 5 mm. deep: corolla 2.5-3 cm. long, with a galea about 1 cm. in 

 length. (C. Tweedyi Rydb. 1. c. 358; C. obtusiloba Rydb. Bull. Torr. Bot. 

 Club 31: 644. 1904.) Open woods in the mountains; throughout our range. 



15. Castilleja lancifolia Rydb. 1. c. 357. Perennial, with a long creeping 

 rootstock, not growing in clumps, 4-6 cm. high, sparingly villous or glabrate, 

 comparatively very leafy: leaves lanceolate, often acuminate, 3-5 cm. long, 

 rather firm, 3-nerved, the upper seldom if ever cleft: calyx and corolla as in 

 the preceding species: corolla about 3 cm. long, with a galea slightly over 1 cm, 

 in length. (Very near to C. Suksdorfii Gray, Proc. Am. Acad. 22: 311. 1877, 

 which has a longer corolla with galea as long as the tube.) Rich soil among 

 shrubs, mountain sides; Colorado to Montana. 



16. Castilleja dubia A. Nels. The woody caudex short, giving rise to few 

 or several slender, simple, ascending or erect stems, 2-3 dm. high; pubescence 

 sparse, cinereous, consisting of fine puberulence and some white, soft hairs: 

 the body or axis of the leaf linear, 3-5 cm. long, 3-5 mm, broad, usually with 

 1 or 2 pairs of widely divergent linear lobes which are one third to one half 

 as long as the leaf: bracts shorter, the blade and lobes relatively broader and 

 tending to become scarious, decidedly yellowish or at the summit bright 

 yellow: calyx about 2 cm. long, equally cleft to nearly one third its length: 

 corolla scarcely longer than the calyx; galea and tube subequal; lip almost 

 wanting, not noticeably saccate, truncate and short-toothed. (C. angusti- 

 folia dubia A. Nels. 1. c. 29: 404. 1902.) Denuded slopes of the desert areas; 

 Wyoming. 



17. Castilleja longispica A. Nels. 1. c. 26: 480. 1899. Stems few to many, 

 2-3 dm. high, branched, the branches slender, erect (fascicled); pubescence 

 a short-hirsuteness with a fine puberulence: leaves 2-5 cm. long, 3-cleft to the 

 middle or thereabouts into linear lobes: bracts with dilated base, 3-cleft to 

 the middle or beyond, the middle lobe oblong, obtuse, the lateral linear; spikes 

 dense, slender, often half the whole length of the plant, yellowish: calyx-lobes 

 equal, linear-lanceolate, acuminate, a little shorter than the ovoid tube: 

 corolla 12-15 mm. long, one third longer than the calyx and slightly exceed- 

 ing the bracts; lip triply saccate and conspicuously 3-toothed, the sacs shal- 

 low; galea obtuse or subacute, scarcely longer than the lip. Wyoming to 

 Montana and Idaho. 



18. Castilleja pilifera A. Nels. 1. c. 31: 246. 1904. Perennial, more or 

 less finely pilose throughout; stems several from the crown of a caudex, slen- 

 der and erect from a somewhat decumbent base, 15-25 cm. high: leaves 

 numerous, flaccid, nearly linear, entire or with one or more linear-divergent 

 lobes, 3-6 cm. long: calyx a little shorter than the bracts, equally cleft above 

 and below to the middle; the lobes linear and rarely more than bidentate at 

 apex: corolla about 2 cm. long (shorter than the calyx), tubular; the lip as 

 long as the galea and about one fourth as long as the tube, the linear teeth as 

 long as the obscurely saccate base. [C. pilosa (Wats.) Rydb. 1. c. 361 has 

 been reported from the northwest portion of our range, as has also the very 

 similar ('. villoaa Rydb. 1. c. Both have the calyx deeply cleft on the back 

 (anteriorly) and the short galea twice as long as the lip.] Wyoming to Mon- 

 tana and Idaho. 



19. Castilleja fasciculata A. Nels. 1. c. 26: 133. 1899. Caudex very short; 

 stems few to .several, simple or nearly so, slender, strict and fascicled above, 

 cinereous-pubescent as are also the leaves and inflorescence, 2-3 dm. high: 

 IcMvcsi; ficrn. long, linear and entire to much divided: inflorescence early elon- 

 gaiing into :i close, nillicr slender spike, 8-18 cm. long; bracts light green or 

 indistinctly reddish or yellowish, 14-18 mm. long, 3-cleft below the middle 

 from a broad base, the lateral lobes linear, divergent: calyx equally cleft be-
