puberulent; stem rather slender, 2-3° high, substriate; petioles spathace- 

 ously dilated ; leaves simply pinnate, with a tendency to be bipinnate in the 

 lower pair of leaflets, which are often short-petiolulate ; leaflets 1-6' long, 

 2-4 pairs, ovate to narrowly lanceolate, sharply and somewhat unequally 

 serrate, occasionally entire, veinlets finely reticulated ; rays 10-15 ; umbel- 

 lets crowded ; involucre and involucels none ; flowers small, greenish-yellow 

 or dull-purple ; calyx-teeth obsolete ; stylopodia with a somewhat expanded 

 crenafce margin ; fruit nearly orbicular, 2-3" long, emarginate above and 

 below ; the dorsal wings thick and rather narrow, the lateral expanded and 

 broader than the seed ; vittas rather large ; seed scarcely concave, not sulcate. 

 — Wahsatch and Uinta Mountains ; 7-8,000 feet altitude ; July, August. 

 Specimens collected by Lyall in the Galton and Cascade Mountains are 

 apparently the same, but are only in flower, and the larger leaves are bipin- 

 nately divided. (458.) 



Aechangelica GtMelini, DC. (!.) The specimens are without mature 

 fruit; leaflets broadly ovate, f-14' long, coarsely and unequally dentate, the 

 teeth-cuspidate; involucels wanting or of a few very narrow setaceous bracts; 

 stems 1-2° high. Found in the Uinta Mountains; 10-11,000 feet altitude; 

 August. The species occurs in Massachusetts, in the Eocky Mountains of 

 Colorado, and on the western coast from Behring Strait to Oregon. A. 

 officinalis, to which it is referred by Dr.- Hooker, is found in Greenland, 

 Labrador and northern Alaska. (459.) 



Ferula ^ ■ MULTiFiDA, Gray. {Leptotcenia, Nutt.) Stems 18-2° high, 

 stout, several from a large conical root, simple or branched, naked or with 

 1-2 leaves which are broadly dilated and sheathing at base ; segments of 

 the 3-4-pinnate leaves incisely pinnatifid, with narrow or linear lobes ; 

 involucre deciduous or of 1-2 persistent leaflets ; involucels of several narrow 

 bracts ; umbels of 12-15 rays, 2-3' long ; flowers dull-yellow or brownish ; 

 fruit 4-9" long and 4" broad, about equaling the pedicel. — Much resembling 



'FEETILA, L. Calyx-teetli obsolete or small. Petals broad, with tlie inflexed point usually short 

 and subentire and -with the midrib slightly if at all impressed. Stylopodia small or conical, with a more 

 or less dilated undulate margin. Fruit orbicular or ovate, flattened ; carpels scarcely convex on the 

 back ; the primary dorsal ribs filiform or slightly elevated, the lateral thin, often with a nerved margin, 

 closely contiguous and forming a wing which is entire before the dehiscence of the fruit ; vittiE usually 

 numerous, conspicuous or obscure, very rarely in exceptional carpels but 1-2 in the central intervals. 

 Carpophore free, 2-parted. Seed flattened dorsally. — Perennial, glabrous and often glaucous ; leaves 

 pinnately decompound, the ultimate segments usually filiform or small ; umbels compound ; involucre 

 and involucels of short entire bracts, rarely very small or none : flowers yellow ; fruit glabrous. Bbnth,
