-18. P. Parryi Watson, Proc. Am. Acad. xi. 148. Strictly 
acaulescent, somewhat glaucous, with rather stout peduncles 6 to 
8 inches high from a stout multicipital caudex clothed with old 
leaf-sheaths, puberulent or glabrous: leaves pinnate; leaflets short, 
pinnatifld below to entire above; ultimate segments very small, 
ovate and cuspidate: umbel 5 to 10-rayed, with involucels of a few 
lineal -acuminate bractlets; rays ^ to inches long; pedicels 2 
to 4 lines long, calyx-teeth evident: fruit oblong, puberulent or 
glabrous, to 4^ lines long, 2 to 3 lines broad, with wings not 
half as bioad as body, and filiform dorsal and intermediate ribs: 
oil-tubes 3 to o in the intervals, 4 to 10 on the commissural side.

Mountains of Southern Utah {Parry 75 and 85, Palmer 178, Jones 1864.) 
19. P. Oreganum. Similar to the preceding species, but a 
veiy much reduced cespitose form, not glabrous, with very slender 
peduncles but 1 to 2 inches high, bearing a very small simple um- 
bel, oi sometimes two neai’ly sessile umbellets, and one to few 
matin ed puberulent fruits about 2 lines long; ultimate leaf-seg 
ments very small, linear-oblong, not cuspidate. (Fig. 58.)

20. p. villosum Nutt. Watson, King’s Rep. v. 131. Acau- 
lescent, more or less densely pubescent, 3 to 8 inches high: leaves 
finely dissected, with very numerous narrow crowded segments: 
umbel somewhat equally 4 to 5-rayed, with involucels of ovate to 
lineal usually very tomentose bractlets; rays about an inch long; 
pedicels 1 to 3 lines long: fruit oval, somewhat pubescent, 
lines long, 2i.^ lines broad, with wings half as broad as body, and 
piominent dorsal and intermediate ribs: oil-tubes 3 or 4 in the in- 
tervals, 4 on the commissural side: seed-face plane. (Fig. 54.) 
From N. California (M. K. Curran), W. Nevada, N. Arizona, and New 
Mexico, to Nebraska, Dakota, and N. W. Territory {Macoun, Dawson). 
Specimens eoiieeted by Canby (no. 150) in “Bad Lands,” Little Mis- 
souri, Dakota, June 30, 1883, and by Dawson (no. 2184) along Felly Eiver, 
N- W. T., Juno 28, 1883, for the first time bring the mature fruit to our 
knowledge, from which we have drawn the above characters. The fruit 
becomes smoother with age and may become but sparsely pubescent, in 
which condition it has been mistaken iov P . faeniculaceum.
