involucre, involucels of several small narrow bractlets, and white 
flowers. 
C. SATIVUM L., the common coriander, native of the E. 
Mediterranean region, and extensively cultivated. Lowest leaves 
with broadly ovate or cuneate deeply cut segments. 
Said to be “naturalized” around Santa Fe, New Mexico {Gray, Plant. 
Fendl. 57) and “introduced” in Unionville Valley, Nevada (Wateo«, Bot. 
King’s Exped. 1.31). Also collected in loothi 11s of Kocky Mts., in Colorado _ 
(Parry), and in San Diego county, California {Lyon). Commonly 
escaped from cultivation. Also collected on ballast near Philadelphia 
Penn. (Martinclale), and Portland, Oregon {Henderson). 
6. EURYT^NIA Torr. & Gray, FI. i. 633.— Glabrous 
branching herbs, with pinnately dissected leaves, involucre and in- 
volucels of cleft bracts, and white flowers. 
This genus closely resembles Discopleura, but seems sufficiently dis- 
tinct in its more flattened carpels, thick winged lateral ribs, depressed 
stylopodium, and remarkably broad oil-tubes, which on the commissural 
face are not tubes at all, but broad reservoirs. The fruit characters also 
resemble those of Peucedanum, but the thick lateral wings easily distin- 
guish it, while the general habit is very different from that of our American 
specii^s of Peucedanum. In the thick lateral wings it approaches Lepto- 
tcenia, but the prominent dorsal and intermediate ribs, as well as the broad 
and solitary oil-tubes, separate it from that genus. 
1. E. Texana Ton-. & Gray, 1. c. From 1 to 2^ feet 
high: leaflets long, nari'owly 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. 6.) — E. macro'phylla Birckl. Proc.

7. ANGELICA Linn. Gen. n. 347. — Stout perennials, with 
ternately or pinnately compound leaves, scanty involuci*e or none, 
involucels of small bractlets or none, and lai'ge terminal umbels of 
white ( greeenish-yellow in A. ^innata) flowers. — Inch Archan- 
gelica Hoffm., excl. A. Gmelini DC. 
Archangelica is referred to this genus by Maximowicz, Bull. Acad. 
Petersb. xix. 273. The characters used to separate Angelica from 
Archangelica are its solitary oil-tubes and adherence of the seed to the 
pericarp, and these are found to be unreliabie (for detaiis as to eastern 
species see Botanical Gazette, xii. 60), especially among western species, 
nearly half of which have two oil-tubes in the intervals.
