Desv.), Soledad, Cienfuegos (Prov. Santa Clara), Nov. 
5, 1915, II, Johnston 194; Matanzas (Prov. Matanzas), 
Feb. 7, 9, 1916, II, Britton, Britton & Wilson 14087; Rio

Meibomia tortuosum (Sw.) Kuntze (Desmodium tortuosum 
DC.), Santiago de las Vegas, Feb. 26, 1916, II, Johnston 
149. 
The rust is probably not rare throughout the island in the 
uredinial stage. It has been detected in the phanerogamic her- 
barium of the N. Y. Bot. Garden on Meibomia Scorpiurus, Rio 
San Miguel (Prov. Pinar del Rio), Dec. 17, 1910, Percy Wilson 
9380, and on M. tortuosum near Vento (Prov. Habana), Aug. 13, 
1907, Baker, Tracy & Hasselbring 3079, and near Herradura (Prov. 
Pinar del Rio), Aug. 28-21, 1910, Britton & Earle 6501. 
Through the kindness of Dr. Lindau of the Berlin Museum, 
the senior author has recently been enabled to examine the spores 
from the collection made by Sintenis in Porto Rico, named by 
Hennings Uredo Desmodii-tortuosi, and finds that they are finely 
echinulate, and not truly smooth as described by Hennings, and 
in every way agree with those of the common form. 
The species is only known elsewhere in the West Indies from 
Porto Rico, but has a continental range both north and south. 
It is autoecious, but pycnia and aecia are rarely seen, the latter 
being pale and inconspicuous.

On EUPHORBIACEAE: 
Manihot Manihot (L.) Cockerell (M. utilissima Pohl, 
Jatropha Manihot L.), Santiago de las Vegas, Feb. 4, 
1916, II, Johnston; same, Oct. 13, 1916, Johnston 903. 
The material collected by Mr. Johnston affected the fruit with 
a strong development of uredinia; all other material seen has been 
on the leaves or stems of the plant. 
The species is autoecious, with all spore forms, and i is known
