distinct in transmitted light; cauline leaves opposite, floral alternate, 
inflorescence leafy; calyx-tube 15 mm. long, 1-1.5 mm. thick at base, 
cylindrical 7 mm. thence broadening to 3 mm. at the throat, glandular- 
pubescent, tips obscure in bud; sepals narrowly lanceolate, 5 mm. long, 
hairy at tip; petals 8 mm. long, narrowly obcordate, the sinus apparently 
closed; stamens exserted 3-5 mm., anthers pink; style exserted 4 mm., 
perhaps tardily longer; ovary cylindrical, densly glandular-pubescent, 
two-thirds the length of its leafy bract; the whole flower, including the 
ovary, a deep scarlet; capsule undeveloped. 
Collected near Willoughby Mine, Gold Lake Region, Plumas Co., 
California, Aug., 1919, by Mrs. E. C. Sutliffe. Type in the Herbarium of 
the California Academy of Sciences. Known only from the type locality, 
where it is said to be, at least locally, abundant.

Specimen Examined 
Broncho Creek, Washoe Co., Nevada, Aug. 17, 1904, P. B. Kennedy 
896, the type collection. (UC). 
The four foregoing species form a very interesting group, all being 
small and slender flowered forms. They are, however, quite distinct. 
Z. Hallii differs from Z. glandulosa in the shape of the leaf, the stamens 
and style less exserted, and the remarkably shaped capsules. Z. pulchella 
is very distinct from either of these forms and, from the description, I 
judge it to be as much so from Z. argentea, although I have not had the 
opportunity of comparing them, as the University of California material 
was sent home before the specimen from which I described Z. pulchella 
was sent me by Miss Eastwood, with the intimation that she considered 
it a new species, in which opinion I heartily concur. 
Several forms from Sonora, Mexico, southeastern Arizona and Lower 
California I have left undetermined because of scanty material and lack 
of authentic specimens of Z. Mexicana Presl. It appears to me that 
there are at least three good species in the specimens that came under 
my observation. I am, however, leaving all this group for future con- 
sideration.
