Il, II, Holway 360. 
This species has previously been recorded only from Porto Rico,’ on 
V. albicaulis, V. borinquensis, and V. sericea (V. phyllostachya). The specimen 
from St. Croix, listed with the original description, has since been referred to 
Puccinia (Argomyces) insulana (cf. 7). All but the last mentioned collections 
are from phanerogamic specimens in the herbarium of the New York Botanical 
Garden, obtained by the writer in January 1917. All are previously unrecorded 
hosts. 
5. PuccrinIA VERNONIICOLA P. Henn. in Engler, Pfl. Ost.—Afr. 
c:50. 1895. 
On Vernonia sp., Marangu, Africa, Volk 2257. 
This species has not been seen by the writer and apparently has been 
recorded only from the type locality noted. Only telia and teliospores are 
described. Sypow’ has evidently redescribed this from authentic material and 
his description of the sori (sparsis, rotundatis, 2-2.5 mm. diam., pulvinatis) 
would suggest that it is a lepto-Puccinia and not to be confused with ane form 
yet recorded from North America. 
6. PuccINIA VERNONIAE-MOLLIS Mayor, Mem. Soc. Neuch. 
5:510. 1913.—Aecidium Vernoniae-mollis Mayor, Mem. Soc. 
Neuch. 5:570. 1913. 
This species was described from material collected by Mayor in the central 
Andes, Dept. Antioquia, Colombia, on Vernonia mollis (?). Four collections 
of uredinia and telia were made, two of which correspond in data of place and 
date with collections of aecia on the same host described separately. Judging 
from the description of the aecia (only uredinia and telia having been seen by 
the writer), it would seem probable that the aecia belong in the life history as 
they appear to be of a type common in this group of rusts. If this surmise is 
correct, this species is of the Eriosporangium type. The matter is complicated 
by the fact that Mayor made two collections of another uredo (U. Vernoniae 
This species differs from all other related rusts on Vernonia in the small size 
of the teliospores (14-21 by 30-38).
