ARTHUR AND JOHNSTON: UREDINALES OF CUBA 111 
Baker 1378, May 9, 1906, Baker (Barth. Fungi Columb.

This West Indian rust is undoubtedly heteroecious, but with 
aecia yet unknown. The telia are rarely produced and the con- 
tinuance of the species is probably by urediniospores. It is also 
known from Porto Rico and Guadeloupe.

Oriente), March 12, 1903, II, Holway; Taco Taco (Prov.

This species is undoubtedly heteroecious, like other species of 
the genus. It is at present known only in the uredinial stage, and 
there is much likelihood that when more fully studied may be 
united with earlier named species on other hosts. It was also 
detected in the phanerogamic herbarium of the N. Y. Bot. Garden, 
on same host from Trinidad Mountains (Prov. Santa Clara), 
March 6, 1910, II, Britton & Wilson 5134. It is also known from 
Guatemala, Nicaragua, and from South America.

ON VITACEAE: 
Vitis vinifera L., Hound, March 21, 1903, Holway; San- 
tiago de las Vegas, May 13, 1916, Johnston 70r. 
This imperfectly known rust has not been found on any native 
grape in America. The collections are treated under the name 
Vitis vinifera, but no adequate examination of the cultivated hosts 
has been made to substantiate this assignment. The species is 
abundant in Porto Rico and Jamaica, as well as in the warmer 
parts of North and South America and Japan, and is often quite 
injurious to cultivated grape vines.
