Phacelia sericea ciliosa var. nov. 
Usually taller than the typical P. sericea, often 5 dm. high, not 
silvery, green; pubescence very sparse and short, except some 
long silky hairs on the pedicels and lower portion of the stem. 
This variety has been mistaken for P. Lyadlit and P. idahoensis. 
It has been confused with the first on account of the similar pubes- 
cence, but P. Lyall is a much smaller plant and with less deeply 
dissected leaves. It resembles P. zdahoensis very closely in gen- 
eral habit, but in that species the stamens are only slightly ex- 
serted and the corolla smaller. The variety has the same range 
as the species, but grows usually at a lower altitude. As the type 
may be taken: :

‘ Lappula Besseyi sp. nov. 
Biennial ; stem 5-10 dm. high, hirsute, branched above ; lower 
leaves petioled, 6-15 cm. long; blades spatulate or oblanceolate, 
obtuse, hispidulous and hirsute on the veins ; upper leaves sessile, 
lanceolate; inflorescence branched; bracts small; pedicels in» 
fruit 4-5 mm. long, more or less reflexed; corolla dark blue, 
scarcely over 1.5 mm. wide; fruit about 3 mm. wide; marginal 
spines distinct and in one row; back flat, spineless, but minutely 
hispidulous. 
In general habit this species resembles most ZL. floribunda, but 
is distinguished by the very small flowers and fruit. It grows in 
caiions at an altitude of about 2400 m.
