Piper — New Pacific Coast Plants. 43 



densely viscid-puberulent, striately many-nerved, 7-8 mm. long, the short 

 broadly triangular subequal slightly spreading teeth each tipped with a 

 short spine; corolla purple, viscid-puberulent, 15-18 mm. long, the narrow 

 cylindraceous tube twice as long as the lower lip, the lips wide spreading, 

 the lower somewhat longer; filaments sparsely pubescent. 



Corvallis, Oregon, along a stream, August 7, 1918, C. V. Piper. Closely 

 allied to S. ciliata Douglas and S. pubens (Gray) Heller but easily dis- 

 tinguished by the dense inflorescence and the viscid-puberulent calyx. 

 The character given for the genus in the Synoptical Flora of "filaments 

 naked" requires revision, as they are pubescent in all the species here 

 mentioned. 



Stachys ciliata macrantha, n. subsp. 



Leaves lance-ovate, rounded or subcordate at base, dentate not at all 

 crenate, rather densely and loosely appressed pubescent on each side, the 

 blades 6-10 cm. long about twice as long as the petioles; calyx 10-12 mm. 

 long, tubular, more or less enlarged in the throat, loosely and thinly pubes- 

 cent, the oblong-ovate acute teeth each armed with a short spine at tip; 

 corolla 3-4 cm. long, puberulent.

Penstemon deserticola, n. sp. 



Perennial from loosely branched woody rootstocks; whole plant perfect 

 glabrous except only the leaf margins; stems erect or nearly so, 15-20 cm. 

 high; leaves 6 or 7 pairs, entire, sessile, narrowly oblanceolate, the lower 

 obtuse, the upper acute, thick, pale and somewhat glaucous, glabrous 

 except the finely puberulent margins, 2-4 cm. long; inflorescence narrow, 

 6-10 cm. long; bracts lance-linear, acute, gradually reduced; peduncles 

 short, equalling the calyx; calyx-lobes oblong-ovate, acuminate, broadly 

 and somewhat erosely scarious-margined, 5-6 mm. long; corolla (probably 

 blue) broadly tubular-funnelform, 2 cm. long, entirely glabrous, the broad 

 lobes rounded; sterile filament glabrous; anthers glabrous, split from the 

 tips to but not through the connective. 



Near Desert Well between Button Springs and Silver Lake, Lake County. 

 Ore., alt. 1400 m., July 5, 1894, /. B. Leiberg No. 402. Type in U. S. 

 National Herbarium, sheet No. 404,811. Nearest P. speciosus Dougl., 

 from which it differs by the smaller corolla, differently shaped leaves, and 

 much smaller size. 



Cirsium oreganum, n. sp. 



Weakly armed; stems erect, slender, loosely arachnoid, 60 cm. high, 

 branched from the base, the branches erect; leaves narrowly oblong, the 

 lowermost lobed, the others subentire, or with a few tooth-like lobes, the 

 tip and the lobes or teeth spine-tipped, prickly-ciliate, green and glabrous 

 above, thinly white tomentose beneath, the lowermost petiolate, the
