Arthur: Uredinales of Porto Rico

type was determined by Capt. J. Donnell Smith as Buettneria 
lateralis, but after the Stevens’ collections came to hand the 
original material was again submitted to Capt. Smith who found 
that through some error it had been wrongly reported, and was 
in fact Erythrina glauca. The Holway collection from Cuba was 
first said to be on E. micropteryx, which is clearly an error.

On Lythraceae: 
Cuphea Parsonsia R. Br., Cabo Rojo, June 15, 22/p. 
This is the first collection of this rust in North America. The 
gross and microscopic appearance of the Porto Rican material 
agrees perfectly with that of the type, which was collected at 
Goyaz, Brazil by E. Ule 2001, on an undetermined species of 
Cuphea. 
93. Uredo fallaciosa sp. nov. 
Uredinia hypophyllous, irregularly gregarious on somewhat dis- 
colored spots, roundish, 0.1-0.5 mm. across, tardily naked, pulver- 
ulent, fuscous ; urediniospores ellipsoid or obovoid, 18-23 by 
24-29 /i ; wall pale yellow or slightly fuscous, 1-1.5 fx. thick, moder- 
ately echinulate, the pores obscure.

Psychotria patens Sw., Maricao, April 3, 774 (type) ;

The uredinia are not abundant in these collections. The sori 
are not prominent on the leaf surfaces, merely making an incon- 
spicuous roughening that attracts attention chiefly by the slight 
discoloration. The sori are subepidermal, without paraphyses, 
and have the aspect of forms belonging to species of Uromyces 
and Puccinia. Three rusts with uredinia have been described by 
Hennings from South America, but in the absence of material for 
examination it is not possible to say if any of them include the 
Porto Rican form. 
94. Uredo sabiceicola sp. nov. 
Uredinia largely hypophyllous, scattered singly or in groups of 
2-5 on small discolored spots 0.5-1 mm. across, round, small, 
o. 1-0.3 diameter, dull cinnamon-brown, subepidermal;
