C. SAT1\'UM L., the common coriander, native of the E. 

 Mediterranean region, and extensively culti\ atcvl. Lowest leaves

Said to be "naturalized*" around Santa Fe, New Mexico (rr'ra//, Plant. 

 Fendl. ")7,) and "introducexl" in Unionville YaiUiy, Nevada (ira/xo/i, Bot. 

 King's Exped. JIU). Also eollecled in lootiiilis of Kocky MtH, in Colorado 

 {Parri/), and in San Diego county, California (Liion). Coninioidy 

 escaped from cultivation. Also collected on ballast near Piiiladelphia 

 Penn. {MartindaU-), and Portland, Oregon (HeiitlrrMon). 



G. EURYT.ENIA Torr. A: Gray, Fl. i. (>:«.- (ilabrous 

 branching herbs, with pinnately dissected leaves, involucre anil in- 

 volucels of cleft bracts, and white flowers. 



This genus closely resembles DiHcopIeuru, but seems liulTiciently dis- 

 tinct in its more tiattened carpels, thick winged lateral libs, depressed 

 stylopodium, and remarkably broad oil-tubes, which on the commissural 

 face are not /i(?<p« at all, but broad reservoirs. The fruit characters also 

 resemble those of PeHcefZf(H»«(, but the thick lateral wings easily distin- 

 guish it, while the general habit is very different from that of our Ameiican 

 species of Peucedaniim. In the thick hiteral wings it approaches Lepto- 

 tcniia, but the prominent dorsal and intermediate ribs, as well as the broad 

 and solitary oil-tubes, separate it from that genus. 



1. E. Texana Torr. & Gray, I. c. From J to 'ly. feet 

 high: leaflets long, narrowly linear to oblong, serrate or toothed: 

 umbels 8 to 15-rayed; rays 1 or 2 inches long; pedicels very short: 

 fruit two lines long. (Fig. ().) — E. macrophylla Buckl. Proc.

7. ANGELICA Linn. Gen. n. 847.— Stout perennials, with 

 ternately or pinnately compound leaves, scanty involucre or none, 

 involucels of small brr.ctlcts or none, and large terminal umbels of 

 white (greeenish-yellow in yl. pifinata') flowers. — Incl. Arc/tan- 

 oclica Hoffm., excl. A. GnicHni DC 



ArchangeUea is referred to this genus by Maximowicz, IJull. Acad. 

 Petersb. xix. 273. The characters used to separate Angelicu from 

 A/T/in/((/«'/jca are its solitary oil-tubes and adherence of the seed to the 

 pericarp, and these are found to be unieliable (for details as to eastern 

 species see Botanical Gazette, xli. 60), especially among western spo.'ies, 

 nearly half of which have two oil-tubes in the Intervals.
