Leptotaenia multifidaand L. EatoniCoulterand Rose, These 
do not hold their characters, the dissection of the leaves, shape of 
the seed face, and corky nerve are not good as separating charac- 
ters. The same oil tubes are present in the one as in the other 
bat they are empty in L. multifida generally. The same ten- 
dency is shown in Cymopterus purpureus where, when the oil is 
very abundant, the tubes coalesce and make one large tube in 
each interval. 
Leptotaenia filicina n. sp. Plant 3° high, glabrous; leaves _ 
with wholly inflated petioles, ternate, with segments pinnately 
decompvund into filiform and very short lobes; rays 1-3’ long, 10 
or less; pedicels 3-6” long; involucels of few, inconspicuous bract- 
lets; fruit 6-8” long, 2”’ wide, with narrow and slightly thickened 
margins; oil tube | in the intervals and prominent, 2-4 on the 
commissure, irregular and small; seed face nearly flat, but seed — 
arcuate. This bas the leaves of Peucedanum Grayi, the fruit — 
nearly that of P. bicolor but is flatand thin. It would seem to 
be a Peucedanum with aborted lateral wings, but is nearest to 
L. Salmoniflora C. & R. Gathered in the Seven Devils Mts., 
Idaho, Aug. 5, 1899, at 6000° alt. 
Cymopterus peecunpeg ot var. albiflorus (Nutt.) Pteryxia 
albiflora Nutt. T. & G. Fl. 1 6 This often has but one dorsal 
wing developed. the rest ts died to lines or nerves, and it 
shows the weakness of the custom of making such genera as 
Pseudocymopterus, etc., on the low development of dorsal wings. 
The flowers are yellow. This is a well marked variety because 
of the rigid and falcate divaricate leaf segments. Weiser, Idaho, 
July 6, 1899. An intermediate form is from the Cuddy Mts., 
Idaho, July 11, 1899.
