with tubercles aud is even thicker than that of P. helianthi. The stalk 
is rather evanesceut; its length differing on the different host plants. 
On Vernonia fasciculata , as has been stated by Professor Burrill, the 
length of the stalk is about four times that of the spore; on Vernonia 
Baldwinii it is much shorter, attaining only once or one and a half 
times the length of the spore. We might, therefore, distinguish two 
varieties of P. vernonice aud designate the one on Vernonia fasciculata 
as var. longipes , the other on Vernonia Baldwinii as var. brevipes. I 
have not been able to examine this fungus ou other host plants.

NEW SPECIES OF UREDINE/E. 
By J. B. Ellis and S. M. Tracy. 
Puccinia HEMizoNiiE, n. s. ii, in.— Amphigenous; spots yellowish, 
rather large; sori small, scattered or sometimes confluent, surrounded 
by the remains of the ruptured epidermis; uredospores subglobose to 
oval, very slightly echiuulate, thick walled, dark colored, 16-2 by 24-30/1; 
teleutospores obovate, occasionally three-celled, slightly constricted, 
apex much thickened, rounded or blunt pointed; epispore smooth, 
22-24 by 45-48//; lower segment lighter colored and tapering below to 
the flexuous, hyaline pedicel which is more than double the length of 
the spore. On Hemizonia truncata , Oregon. 
iEciDiUM oldenlandianum, n. s. —Hypophyllous; secidia few in a 
cluster, 80-100/1 iu length, the mouth but little split and not recurved; 
spores globose or sometimes slightly angled; epispore thin, smooth, 
bright yellow; 14-16//. On Iloustonia cwrulea , Starkville, Mississ¬ 
ippi, April, 1888. Although the name u Oldenlandia v is obselete as 
applied to this host, the name given to thisiEcidium on account of the 
name “ houstoniatum” being already occupied by the JEcidium houston- 
iatum , Schw., from which this differs in the longer, narrower secidia, 
smooth spores, aud spermogonia rare or wanting. 
-ZEcidium malvastri, n. s .—Hypophyllous; spots light yellow ; 
mcidia clustered, somewhat circiuate, short, the spreading border rather 
narrow, spores subglobose or ovate, epispore thiu, minutely tubercu- 
late; 15-18 by 18-22//; spermogonia unknown. On Malvastrum Munro- 
anum , Albuquerque, New Mexico, Tracy, June, 1887. 
Newfield, New Jersey.
