wide, one to three inches long; heads small and narrowly oblong; 

 lower bracts of the involucre with weak prickles, upper ones 

 purplish, acuminate and tipped with a weak point, scarious; 

 flowers much exserted, heads several at the ends of the leafy, 

 spreading branches. 



Fraxinus anomai^a Torr. In this queer ash the leaves are 

 nearly always simple and entire, the three-lobed or divided ones 

 being rare. It is found at Grand Junction and on Mesa Verde, in 

 Colorado, and through Southeastern Utah. 



^- PhaceIvIA splendens n. sp. Annual, erect, about a foot 

 high, usually simple stemmed, sometimes branching from near 

 the base; stems purplish, glandular or glabrous; leaves ovate- 

 lanceolate in outline, pinnately parted into three or four pairs of 

 alternate divisions that are either crenate or bluntly lobed and 

 oblique at base, nearly glabrous, but glandular on the rhachis; 

 scorpioid cyme with a long naked peduncle; flowers on short 

 pedicels; calyx white-hirsute, and slightly glandular, divisions 



- linear-lanceolate, i mm. wide, 4 to 6 mm. long, veiny in age, 

 with longitudinal nerves, slightly surpassing the ripe capsule; 

 corolla bright blue, rarely white, about i cm. in diameter, 

 divisions obtuse; stamens and style conspicuously exserted, 

 7 or 8 mm. beyond the corolla; capsule veiny, glandular, 

 and hirsute; seeds with the central ridge very prominent, 

 cymbiform, favose over the whole surface, but not corrugated. 

 This beautiful Phacelia belongs to the Kuphacelia, near. P. 

 glandulosa and P. Neo-Mexua?ia. It grows on the adobe desert 

 soil, and while not along the edges of irrigating ditches or 

 washes, it was comparatively near by. 



Collected at Grand Junction, May, 1892. 



Pentstemon Moffatii n. sp. Stems several from the root 

 from one to two feet high, erect, scabrous below, glandular hirsute 

 above; radical leaves crowded, ovate-spatulate, entire, decurrent 

 along the petioles which equal or surpass the blade in length; 

 lower cauline leaves spatulate with long, broad petioles which 

 are connate-clasping; upper, ovate-lanceolate, closely sessile by 

 a cordate base obscurely dentate at the apex or entire; thyrsus 

 interrupted, the many-flowered clusters about an inch apart;
