110 ARTHUR: NEW SPECIES OF UREDINEAE 
[phanerogamic] specimen is Arizona, yet all the specimens in our 
herbarium upon which Dr. Vasey left a record, many of them 
with numerous notes and descriptions, are from New Mexico, 
and what I regard as the type of the species in spite of the pub- 
lished locality is from New Mexico.”” Professor Hitchcock kindly 
sent a portion of the rusted leaves from the phanerogamic speci- 
men, which proved to be identical in microscopic characters with 
the Ellis specimen. It is clearly evident that only one collection 
of the rust is known, partly in the Ellis collection in New York, 
partly in the Farlow Herbarium at Cambridge, and partly in the 
National Herbarium at Washington, which was collected by Dr. 
George Vasey at Santa Fe, New Mexico, in 1884,and communicated 
to Mr. Ellis by F. L. Scribner. The dark color of the spores must 
have led Mr. Ellis to call it Uromyces, thinking he had telia rather 
than uredinia. No trace of teliospores has yet been discovered. 
The species of -Uromyces, which had been commonly called 
U. Aristidae, having urediniospores unlike those of the present 
species, and with teliospores usually present, was named U. 
seditiosus by Dr. F. D. Kern (Torreya11:212. 1911), who pointed 
out the peculiar situation regarding the Ellis_material. Again 
it seems desirable to explain the chain of circumstances making it 
necessary to give a new name to this imperfectly but long recog- 
nized rust. Although the teliospores are not known it will be 
placed under the genus Puccinia for convenience in listing.

II. Uredinia hypophyllous, numerous, in lines, often confluent, 
elliptic, 0.5-1.3 mm. in length, long covered by epidermis, chest- 
nut-brown; paraphyses peripheral, usually erect, clavate-capitate, 
15-18 by 32-55, the wall pale cinnamon-brown, 2-2.5 u thick, 
thicker above, 7-10; urediniospores broadly ellipsoid or obovoid, 
18-24 by 26-32; wall chestnut-brown, 1.5—2 u thick, uniformly, 
finely and closely echinulate, the pores usually 4, equatorial. 
III. Telia similar to uredinia; teliospores oblong or oblong- 
ellipsoid, 16-19 by 35-48, usually rounded above and below, 
moderately constricted at septum; wall chestnut-brown, 1-2 u 
thick, thicker above, 5—7 u, smooth; pedicel concolorous, fragile.
