apparently cleft nearly to the base: its lobes nearly linear, scarious 
on the slightly broadened base, acuminate and aculeate above, 
7-8 mm. long: corolla usually a deep pink, shading to lighter or 
even white; its tube a half longer than the calyx; its lobes narrowly 
ovate, rounded and obscurely denticulate at summit, about 8 mm. 
long: style and the longer stamens as long as the corolla tube: 
capsule large, spreading the calyx lobes apart, 4-5 mm. long: seeds 
oblong-ovate, rugulose and minutely puncticulate. 
It might be referred to the P. caespitosa group but for the usually 3-5- 
flowered cymes which relate it to the Kelseyi group (5 species), and of these it 
is most nearly related to P. pinifolia Brand., which is erect and with calyx 
and pedicels pilose and not glandular. 
Macsripe tells me this is common on the dry bench lands in the vicinity 
of New Plymouth, in the Payette Valley. His collection, no. 73, New Plymouth, 
May 20, 1910, supplies the type. 
Phacelia luteopurpurea, n. sp.—Slender annual, sparingly 
branched from the base and upward, hispidly short-hirsute, 1-2 
dm. high: leaves 2-5 cm. long, somewhat irregularly bipinnate, 
the oblong-linear lobes rarely few-toothed: inflorescence rather 
densely and conspicuously dark glandular-pubescent: sepals 
linear, spatulate, as long as the corolla tube and exceeding the 
Mature capsule, hispid as well as glandular: corolla narrowly 
campanulate; the tube yellow or yellowish, only 3-4 mm. long, 
more than twice as long as the broadly rounded spreading purple 
lobes: stamens nearly as long as the corolla tube, inserted in the 
Margin of pocket-like depressions near the base but without any 
vertical folds: style 2-cleft at apex only: capsule ellipsoidal, 
2mm. or more long; the ovules about 16; the seeds often fewer, 
irregularly oblong, with fine transverse acute rugulae. 
Most nearly related to P. bicolor Torr., but at once distinguished by its 
glandular pubescence and short corolla. "These two, with P. glandulifera 
Piper, P. Ivesiana Torr., and P. Fremontii, are the members of the section 
Evctypta Wats. (Micnoomnerns A. DC.).
