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. 82.) 



Milford, Utah, June 18, 1880, ai 5,000 feet altitude (Jones 17!i2). Distri- 

 buted as Leptota'nia (Peucedanum) Newberrt/i- 



The dorsal and intermediate fruit wings of this species are very 

 peculiar, but it simulates C- Xeivberrni so completely in other regards that 

 there can be no question of relationship. 



8. C. Parryi. Resembling the two other species in habit : 

 leaves small, ovate in outline, bipinr.ate, v/ith very small oblong 

 segments: involucels of more or less united bractlets : fruit Vvith 

 wings as in the last, but the dorsal and intermediates much more 

 prominent, giving the fruit a Crwo//e/v/.s-like appearance: oil-tubes 

 very small, 5 to 8 in the inter\als, 10 to 14 on the commissural 

 side. ( Fig. 33.)

 Wyoming expedition. 



This species resembles Ciimopterus Fendleri somewhat, but the char- 

 acter of its wings and its habit place it with the two species above. It is 

 the species of Colopfeyra which looks most towards Cymopteruti; while the 

 same may be said of C Newherryi in relation to LeptotcEnia- C. Jonesii 

 occupies a strictly intermediate position between the other two species. 



15. LEPTOT.ENIA Nutt. Torr. k Gray, Fl. i. (529. Tall 

 and stout (except in the anomalous A. a)ioniala) 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,
