leaves rather numerous on the crowns, few and distant on the 

 stems, simple or more general!}- with a pair of divergent, lanceo- 

 late lobes on the petiole near the base of the blade, appresscd-hir- 

 sutc, with a finer pubescence intermingled ; blade oblong, subacute, 

 5-10 cm. long, 1-3 cm. wide : petioles broad, the lower about 

 equaling the blade, shorter upwards, the upper leaves nearly ses- 

 sile : inflorescence at first crowded, the cyme becoming more open 

 with age as its short circinate spikes unroll and lengthen : sepals 

 oblong-linear, in anthcsis shorter than the corolla, lengthening 

 Avith age, in fruit about 8 mm. long : corolla light blue, about 

 5 mm. long, the lobes obtuse, entire or nearly so, half the length 

 of the tube, appendages inconspicuous and thin, united at the base 

 of the filament : the filaments exsertcd, distinctly hirsute ; style di- 

 vided about half its length, glabrous. 



At once distinguished by its small, biennial root, its strict habit, 

 its ample leaves and accessory leaflets and hirsute stamens. Its 

 habitat too is quite different from the other species, as this occurs 

 in the moist loam of mountain valleys. . Type specimen in Herb.

Castilleia fasciculata 



Perennial : taproot short, more or less branched below : cau- 

 dex very short, scarcely more than a woody enlarged crown on 

 the taproot : stems from a few to several from the crown, simple 

 or nearly so, moderately slender, somewhat spreading at the base, 

 very strict and fascicled above, cinereous-pubescent as are also the 

 leaves and inflorescence (pubescence somewhat unequal — from 

 puberulent to subhispid), 2-3 dm. high : leaves very variable, 3- 

 6 cm. long, from nearly linear-entire to much divided, the lobes 

 short or the leaves divided much beyond the middle, usually 3- 

 lobed, the lateral lobes linear, widely divergent and shorter than 

 the middle : inflorescence early elongating into a close, rather slen- 

 der spike, 8-18 cm. long, constituting half, or even more, of the 

 length of the stem : bracts not conspicuously colored, light green 

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

 the middle from a broad base, the middle lobes lanceolate, nearly 

 as long as the corolla, the lateral lobes linear, divergent, shorter 

 than the middle one : calyx equally cleft before and behind, the 

 lobes short-bifid : corolla hardly exceeding calyx and bracts, galea 

 short, not more than half as long as the tube, and twice as long as 

 the lip : lip slightly ventricosc but not callous,'its three teeth short- 

 oblong, obtuse, as long as the ventricose portion : stamens mostly 

 included in the galea ; style exsertcd.
