Piper : Noteworthy Northwestern Plants 399 



spike : calyx tubular, more or less villous, I cm. long, equally 

 cleft before and behind, the segments one half as long as the tube, 

 each again deeply cleft so that the four triangular acuminate calyx- 

 lobes are subequal : corolla greenish except the margins of the 

 galea and the lower lip which are dull purplish, tubular, minutely 

 glandular, 12 mm. long, the blunt galea only one third the length 

 of the tube, slightly exceeding the saccately 3-lobed lip, the free 

 portions of which are oblong, obtuse, and slightly longer than the 

 ventricosities, each of which bears two smaller swellings on its 

 summit : anthers orange-yellow, slightly extruded : stigma capi- 

 tate, 2-lobed, extending beyond the galea. 



Wallowa Mts., northeastern Oregon, 9000 ft. alt., W. C. Cusick, 

 no. 2094, collected August 23, 1898, and again July 28, 1899. The 

 1898 plant was distributed as " Castillcia Lemmoni Gray?" to 

 which the new species has some relation. The calyx and corolla 

 are, however, very different. 





Castilleia angustifolia Whitedii var. nov. 



Stems clustered on a woody caudex, erect, 2-^ cm. high : 

 leaves all entire, lanceolate, 2-3 cm. long; bracts broader than 

 the leaves, the uppermost 3-lobed ; otherwise as in the type. 



Wenatchea, Wash., Kirk Whited, no. 1141, collected June 



11, 1899. Particularly interesting as being markedly different 



from all its immediate allies in having entire leaves.

Shrub 2-4 meters high with slender erect stems, the bark gray 

 and smooth : branches erect or little spreading ; branchlets shining, 

 yellow, very brittle, glabrous or sometimes puberulent, slightly 

 glaucescent : leaves lanceolate or oblong, or oblong-obovate, 

 mostly acute, 3-6 cm. long, or on vigorous young shoots even 

 12 cm. long, about one fourth as wide, above green and sparsely 

 appressed puberulent, beneath velvety with a persistent silvery 

 tomentum, entire or obscurely repand-crenulate ; midrib yellow, 

 conspicuous, bearing about 15 pairs of primary veins, stipules 

 commonly present, free, lunate, acute, ..5 cm. long or less : aments 

 sessile, appearing before the leaves, or the pistillate sometimes on 

 a very short peduncle that bears 2 or 3 small leaves : pistillate 

 aments stout, oblong, 2-3 cm. long, or in fruit 4-6 cm., densely 

 flowered; scales black, persistent, oblong, obtuse, 1.5 mm. long,
