added: akenes oblong-reniform, light gray, minutely reticu- 
ate. - 
"8. P. BoLANDERI — Horkelia Bolanderi, Gray, Proc. Am. 
Aead. vii. 338 (1868); Brew. & Wats. Bot. Cal. i. 182.—Here 
the akenes are ovate-reniform, dark colored and vitreous- 
shining although minutely granular under a good magnifier. 
The species was rediscovered, near Epperson's Ranch, in 
Colusa County, Cal., in 1884, by Mrs. Curran. 
9. ' P. Dovezasn — Horkelia fusca, Lindl. Bot. Reg. l. c. 
(1837); Torr. & Gray, l. c.— There is a Mexican P. fusca of 
Chamisso. 
10. ‘P. crnzara. Green, but with some white silky-villous 
pubescence: radical leaves 6 inches long or more, the leaflets 
crowded and imbricated in more than 20 pairs, each primary 
leaflet divided into 3 oblong-linear entire secondaries : stems 
a foot or two high, slender, erect ; cymes dense, flowers small : 
calyx minutely glandular, the segments lanceolate, much 
longer than the turbinate tube, and, with the narrower and 
somewhat shorter bracteoles, villous-ciliate : petals with nar- 
rowly oblong lamina and a slender claw of equal length : 
stamens 10; filaments scarcely dilated (narrowly subulate) ; 
carpels 1—3. a 
A single specimen, obtained in Owens’ Valley, Inyo County, 
California, 1873, by the late Dr. Albert Kellogg. 
The inflorescence is so like that of the common species, P. . 
Douglasii, that without the leaves no one would be likely to 
suspect it of being anything else; yet, with its totally differ- 
ent foliage, petals and stamens, it can not be confounded with 
it. It is, moreover, in the character of its filaments as well 
as in foliage, an Ivesia, notwithstanding its intimate relation- 
ship with Horkelia fusca, and so increases the number of 
those species which will reduce any recognition of these 
genera to a piece of artificial systematizing such as even 
Linneus would have deprecated.
