unequal oblong foliaceous bractlets: fruit sessile or nearly so, 3 
lines long, with very thick lateral wings and filiform dorsal and 
intermediate ribs: oil-tubes very small, 4 to 8 in the intervals, 8 to 
10 on the commissural side: seed-face somewhat concave. (Fig*

2. C. Jonesii. Closely resembling the preceding in habit 
and foliage: involucels of short equal ovate bractlets more or less 
united into a cup: fruit with corky and undulate dorsal and inter- 
mediate wings (usually a dorsal wing on one carpel and two inter- 
mediate wings on the other). (Fig. 32.) 
Milford, Utah, June 18, 1880, at 5,000 feet altitude {Jones 1/92). Distri- 
buted as Leptotmnia {Pence danwm) Newberryi. 
The dorsal and intermediate fruit wings of this species are very 
peculiar, but it simulates C- Newberryi so completely in other regards that 
there can be no question of relationship. 
3. C. Parryi. Resembling the two other species in habit : 
leaves small, ovate in outline, bipinnate, with very small oblong/ 
segments: involucels of more or less united bractlets: fruit v/ith 
wings as in the last, but the dorsal and intermediates much more 
prominent, giving the fruit a Cymopterus-\\\<.e appearance: oil-tubes 
very small, 5 to 8 in the intervals, 10 to 14 on the commissural 
side. (Fig. 33.) 
Little Sandy, N. W. Wyoming {Parry in 187.8), collected in Capt. Jones’ 
Wyoming expedition. 
This species resembles Cymopterus Fendleri somewhat, but the char- 
acter of its wings and its habit place it with the two species above. It is 
the species of Coloptera which looks most towards Cymopterus', while the 
same may be said of C- Newberryi in relation to Leptotoenia- C. Jonesii 
occupies a strictly intermediate position between the other two species. 
15. LEPT0T.P:NIA Nutt. Torn & Gray, FI. i. 629. Tall 
and stout (except in the anomalous F. anomala) glabrous nearly 
acaulescent perennials, with thick often very large fusiform roots, 
usually large (except in L. anomala) pinnately decompound 
leaves, involucre of few bracts or none, involucels of numerous 
small bractlets, and yellow or purple flowers. 
This genus was referred to Ferula by Gray, Pioc. Am. Acad. vii. 348, 
but kept distinct by Bentham & Hooker, Gen. Plant, i. 922. Ferula, Peu-
