rate, the terminal leaflet mostly with wedge-shaped base; stem leaves somewhat 
similar, 2 or 3 times ternate; leaflets often larger, somewhat oblique at base; petiole 
short with a broad sheath, scarious throughout; peduncles stout, very variable in 
length, 8 dm. long or less, sometimes wanting; involucre a simple or 3-lobed leaf; 
involucels of a few green linear or lanceolate bracts much longer than the fruit; 
rays very variable, 5 to 10 em. long; pedicels 4 mm. long; flowers yellowish-pur- 
ple(?); fruit broadly ovate, 6 mm. long, rounded at base, acute; ribs rather sharp 
and prominent; interval narrow, with a single large oil-tube; styles short, with 
conical stylopodia; seed with a narrow rather shallow suleus, strongly indented

Collected by Mr. C. G. Pringle, in wet canyons, Sierra de San Felipe, altitude 9,000 
feet, June 1, 1894 (No. 4675), 
Arracacia brevipes! Coult. & Rose, sp.nov. 
Stems 9 to 18 dm. high, branching, glabrous; leaves twice ternate, leaflets 
ovate, 18 to 25 mm. long, slightly lobed and serrate, acute, paler and slightly sca- 
brous beneath; peduncles generally long (2.8 dm. or less); involucre a single 
leaflet or wanting; involucels of several linear bracts longer than the flowers: 
rays rather variable in length, 2.5 to 7.5 em, long; pedicels, 4 mm. long; flowers 
yellow; fruit ovate, 5 to 6 mm, long, with long reflexed styles and conical stylo- 
podia; ribs not prominent; oil-tubes solitary in the intervals, with 1 or 2 shorter

inclosing a central cavity. . 
Collected on the Sierra de San Felipe, altitude 10,000 feet, by Mr. C. G. Pringle, 
September 17, 1894 (No. 5545); and by Mr. E. W. Nelson, August 20 to 30, 1894 
(No. 1097). ; 
Arracacia (?) filiformis Coult. & Rose, ined.? 
Collected by Mr. C. G. Pringle on rocky summit ridges, Sierra de San Felipe, alti- 
tude 10,500 feet, June 26 and August 4, 1894 (No. 4714); and by Mr. E. W. Nelson 
on the summit of Mount Zempoaltepec, altitude 11,400 feet, July 9, 1894 (No. 621), 
Sierra de San Felipe, altitude 9,500 to 11,000 fect, August 20 to 80, 1894 (No. 1088). 
Arracacia nelsoni Coult. & Rose, sp. nov. 
Stems 2.5 to 5 em. high, from slender creeping roots, slightly branching; leaves 
twice ternate; leaflets ovate, 18 to 35 mm. long, serrate, acute, paler and glabrous 
beneath; peduncles 5 to 10 em. long; involucre a single searious bract, 6mm. long; 
involucels of several filiform bracts about the length of the pedicels; rays 2.5 to 5 
em. long; pedicels 4mm. long; fruit ovate, 5mm, long, beaked, with prominent ribs; 
styles long, erect; stylopodia conical; oil-tubes solitary in the intervals, 4 on the 
commissural side; seed with a narrow sulcus extending to the middle. 
Collected by Mr. EF. W. Nelson from the tops of the mountains 18 miles southwest 
of the city of Oaxaca, between altitude 7,500 to 9,500 feet, September 10 to 20, 1894 
(No. 1882). There is some confusion regarding this number, as Mr, Ne'son’s notes 
under it refer to a composite. The number may be duplicated. 
Arracacia ovata Coult. & Rose, sp. nov. 
Stems 12 to 18 dm. high; radical leaves twice ternate, with long petioles; leaflets 
i-Ainericana 
to Tauschia coulterit Gray, Pl. Lindh. ii, 211 (1850). Coulter’s species, however, came 
from Real del Monte, and while it is like 4. brevipes in habit, has different foliage, 
longer pedicels, ete, It does not belong with Tauschia nudicaulis but its relations 
are with Arracacia, and it may be referred as Arracacia coulteri (Gray ).—J.N.R. 
?The technical description and illustration of this species will appear in a future 
number of Hooker's cones Plantarum. It was my intention to republish it here, but 
owing to some delay, the numberof the cones to contain the description has not yet 
been issued. I have, therefore, withdrawn the description from the proof.—J.N. R.
