by the lead-colored cuticle which is at length ruptured aud forms a 
border around tlie margin. Spores elliptical, oblong or obovate, rounded 
and thickened above, smooth, constricted at the septum, 27-10 by 20-23/* 
on rather stout pedicels about as long as the spores. This is quite dis¬ 
tinct from P. thlanpeos , Schubert, which has the sori paler and liypo- 
phyllous and has no secidium. P. aberrans (N. A. F. 1834) is also dif¬ 
ferent from this. 
Puccinia aralia], ii. s. On ginseng (Panax trifolium ), Massachu¬ 
setts, May, 1888, Miss C. H. Clark and M. C. Carter, III. Parts at¬ 
tacked more or less distorted. Sori caulicolous and foliicolous, minute, 
clustered in tufts l-2 mm across, naked and of a dark-brown or nearly 
black color, not on any definite spots though the affected leaves turn 
more or less distinctly light yellow, the yellow area occupying a large 
part of the leaf. On some of the leaves the sori were placed opposite 
ou each side of the leaf, but in this case those on the upper surface were 
smaller. Spores oblong or oblong-elliptical, with fine, granular contents, 
and grauular-rougheued, pale-brown epispore scarcely thickened at the 
apex, which is either regularly rounded aud obtuse or capped with a 
small hyaline papilla. Scarcely constricted, 25-35 by 15-20/* on rather 
slender pedicels, about as long as or a little longer than the spore itself. 
Puccinia xanthiifolia, n. s. (P. compositarum , Schlect. in 1ST. A. 
F. 2252.) Cn leaves of Iva xanthiifolia , Manhattan, Kans., October, 1888. 
Dr.W. A. Kellerman. I and II not seen. III. Sori hypophyllous scat¬ 
tered, bare, black, J-l m,u diameter, tuberculiform, compact. Teleuto 
spores, elliptical or obovate-elliptical, smooth, rounded and thickened 
at the apex aud mostly with a distinct papilla, constricted at the sep¬ 
tum, deeply colored 35-45 by 18-23//. on long (70-80,a), slender, sub- 
persistent pedicels. This is a very different thing from P. composita- 
rum , for which, by some inexplicable error, it was distributed iu N. A. F. 
P. intermixta , Pk., according to authentic specimens, is also very dis¬ 
tinct from this. # 
Puccinia consimilis, n. s. On leaves of Sisymbrium Uni folium. Hel¬ 
ena, Mont., May, 1889. Rev. F. D. Kelsey, No. 53. I and III. Hy¬ 
pophyllous. Acidia covering the greater part of the lower surface of 
the leaf. Shallow, soon open, margin sublacerate-toothed and narrowly 
reflexed. iEcidiospores pale yellow, subglobose or subovate, smooth, 
20-23// diameter. 
III. Sori miuute, J mm diameter, crowded but not confluent and like 
the recidia occupying the greater part of the lower surface of the leaf, 
chestnut brown, closely surrounded by the ruptured epidermis, but 
naked above almost from the first. Teleutospores obloug-obovate, 
constricted, 25-42 by 18-22//, thickened at the apex, with or without 
a papilla, which when present is either central or oblique, upper cell 
mostly broader and darker, lower cell also generally rounded at the 
base, pedicels as long as or longer than the spores.
