lets; upper leaves much reduced, often with linear leaflets; peduncles either want- 
ing or short; pedicels 4 to 5 mm. long. 
Collected by Mr.C.G. Pringle in pine woods on hills of Pascuaro, State of Mich 
oacan, October 25, 1893 (No. 4620). It was distributed by Mr. Pringle in his 1893 set 
as Smyrnium egopodioides. 
Mr. Hemsley in a recent letter states that Seeman No. 2134 belongs here. As he — 
says, itis very doubtful whether this is the true Smyrnium @gopodioides, 
DD. Radical leaves with linear leaflets; involucre and involucels wanting. 
4. Museniopsis tuberosa Coult. & Rose, sp. nov. 
Biennials from a small round or spindle-shaped tuber; stems very slender, some- 
what zigzag, 3 to 6 dm. high, much branched above; leaves much dissected into 
linear entire segments, 4 to 10 mm. long; peduncles short, 1.2 to 3.6 em. long; rays 
(2 to 6) 12 to 25 mm, long; pedicels 1 to 5 mm. long; fruit oval, 2mm, long, obtuse. 
Collected by Mr. C.G. Pringle on Sierra de San Felipe, altitude 7,500 feet, August 
7 and November 17, 1894 (No. 4868); and by Mr. E. W. Nelson in oak woods on the 
mountain ridge on west side of the Valley of Cuicatlan, altitude 7,500 to 8,000 feet, 
November 10, 1894 (No. 1900a); from the top of the Sierra Madre near Chilpancingo, 
State of Guerrero, altitude 9,000 to 10,200 feet, December 24, 1895 (No, 2241). 
CC. Perennials from long slender and sometimes thickened roots. 
EK. Radical leaves with linear elongated leaflets. 
F. Glaucous; fruit obtuse, with obsolete ribs; lateral umbels often sessile. 
G. Involucral leaf 1, elongated; fruit smaller and leaflets shorter 
than in the next, 
5. Museniopsis ternata (Watson); Mulophus ternatus Watson, Proc. Amer. Acad. 
xxiii, 276 (1888). 
Museniopsis ternata filifolia Conlt. & Rose, var. nov. 
Much like the type but more slender, with filiform leaflets, longer pedicels, ete. 
Collected by Mr. C,G, Pringle in canyons, Sierra Madre, Chihuahua, October 1, 
1887 (No. 1519). 
This may prove a distinct species. Dr. Watson thought it a possible variety of 
E. peucedanoides, but to us its relationships seem nearer the above, Dr, Watson’s 
herbarium name is continued. 
GG, Leaflets very long: involucre wanting; fruit large for the genus. 
6. Museniopsis schaffneri Coult. & Rose, sp. noy. 
Roots slender and elongated; stem tall, slender, glabrous, and glaucous; radical 
leaves twice ternate; leatlets linear, elongated, 10 cm. long or less, with strong 
medial and intermarginal nerves; rays spreading, slender, 4 to 7.5 cm. long; pedi- 
cels slender, 6 to 10 mm, long; involucre and involucels wanting; fruit (immature) 
broadly ovate, 4 mm. long, cordate at base, capped with low stylopodia. 
Collected by Dr. J. G. Schattner in ‘“‘rupestris prope San Miguelito,” San Luis 
Potosi, 1876 (No. 5), and in 1879 (No. 550); also by Parry & Palmer from the same 
State, 1878 (No. 293). 
This species has been confused with Lulophus peucedanoides, from which it is dis- 
tinct, differing chiefly in its longer rays and pedicels, the shape and size of fruit, 
distinct stylopodia, and perhaps in leaflets and habit. 
FE. Glabrous, not glaucous; involucre wanting; no umbels sessile. 
H. Fruit ovate or oblong, longer than broad, with a short beak and 
rounded base; ribs thick, filiform. 
7. Museniopsis peucedanoides (II. B. K.); Cnidium peucedanoides H. B. K. Nov. 
Gen. et Sp. v, 15 (1821); Lulophus peucedanoides Benth. & Hook. Gen, Pl. i, 885 (1867). 
Collected from Sierra de San Felipe by Mr. C. G. Pringle, October 13, 1894 (No. 
5543); and by Mr. E. W. Nelson, August 20 to 30, 1894 (No. 1190). 
HA. Fruit broadly ovate, broader than long, cordate at base, obtuse; 
tibs filiform.
