and terminal, either elongated or nearly wanting; rays numerous (25 to 35), the 
longer on: s about 5em. long; involucre wanting, or of a few linear bracts; involucel 
bractlets filiform; flowers white; rruit oval, 3mm. in diameter; dorsal and intermedi- 
ate ribs slightly winged, lateral wings thin; oil-tubes solitary in the intervals, 4 on 
the commissural side; stylopodium conical; seed indented beneath the oil-tubes and 
with a tlat face. 
Collected by FF. W. Nelson, September 10 to 20, 1894 (No. 1405), and by Mr. C. G. 
Pringle in wet meadows of Sierra de Clavellinas, altitude 9,000 feet, October 16, 1894 
(No. 4996). Much like 4. seatoni, but with larger leaves, smaller leaflets, more 
numerous rays, smaller fruit, etc. 
Here also should be referred Bourgeau’s No, 2677, fide Hemsley in lit. 
The two following species, although closely related to the above, appear to be 
distinet: 
Angelica seatoni Coult. & Rose, sp. nov. 
Leaves twice ternate or somewhat pinnate; leaflets ovate, 3.7 to 6.2 cm. long, 
rather long-pointed, somewhat tapering at base, especially the terminal ones, sharply 
serrate, slightly pubescent on the veins; peduncles axillary and terminal; rays rather 
numerous (15 to 20), the longer ones 5 cm. long; pedicels numerous, 12 mm. long, 
more or less pubescent, as also the rays and peduncle; involucre none; bractlets 
of the involucels filiform; flowers probably white; fruit oblong, 5mm. long, 4mm. 
broad; wings about as broad as body, thick and corky; dorsal and intermediate 
ribs prominent; oil-tubes solitary in the intervals or two in the lateral ones, 4 on 
the commissural side; stylopodium conical; seed indented beneath the oil-tubes 
and with a flat face, 
Collected by Mr. Henry Seaton on Mount Orizaba, Mexico, July 20, 1891 (No. 65), 
and distributed as Angelica mexicana Vatke. 
This species differs from .1. nelsoni in having more simple leaves, broader leatlets, 
few rays, and larger fruit with thicker wings. 
Here we would refer Botteri’s specimens from this region. That in the Gray 
herbarium is No. 83, while the specimen Mr. Hemsley refers to in Biol. Centr.-Amer. 
i, 567 is No. 870. This latter number is probably wrong, as C. Wright’s MS, list of 
Botteri’s collection, now in the National Herbarium, refers if to a Eupatorium. 
Angelica pringlei Coult & Rose, sp. nov. 
Rather low, 6 to 9 dm. high; leaves 2 to 3 times ternate; leatlets ovate, 2.5 to5 
em. long, doubly serrate, mostly rounded or truncate at base, slightly pubescent on 
the veins, the lateral distinetly petioled; rays of the umbel 25 to 80, 5.7 to 6.2 
em. long; pedicels 8 to 6 mm. long; tlowers pinkish or white; fruit oval, 4 mm, in. 
diameter; wings a little broader than body, thin; dorsal and intermediate ribs prom- 
inent; stylopodium low, depressed; oil-tubes solitary in the intervals or2in the lat- 
eral, 4 on the commissural side; seed strongly indented beneath the oil-tubes, with 
a broad, shallow, concave face. 
Collected by C. G, Pringle along streams, Sierra de las Cruces, State of Mexico, 
September 11, 1892 (No. 5209). 
This species differs from 4. nelsoni in being of lower stature, with broader and 
somewhat doubly serrate leaflets and fewer rays. 
Apium ammi (Jacq.) Urban, Fl. Bras. xi, pt. 1, 341, t. 91 (1879); Sison ammi Jacq. 
Hort. Vindob. ii, t. 200 (1772); Apinm leptophyllum I’. Muell. 
Collected by C, G. Pringle on the Sierra de San Felipe, altitude 7,500 feet, Sep- 
tember 11, 1894 (No. 5546); also collected by E. W. Nelson at Orizaba, January 28, 
1894 (No. 17); and by Mr. C. G. Pringle in Baranea near Guadalajara, Jaliseo, July 
10, 1894 (No. 5552). 
Arracacia bracteata Coult. & Rose, sp.nov. 
Perennial; stems 9 to 12 dm. high, glabrous and glaucous; radical leaves from 3 
to 4 times ternate, with long petioles; leaflets ovate, acute, 2.5 to 5 em. long, ser-
