17 
were collected by Charles Wright on Limnanthemum 
Grayanum Griseb. {Menyanthaceae) , in Pinar del Rio, 
Cuba, December, 1857 or 1858. No other West Indian 
stations are known. 
1 18. Puccinia Cordiae sp. nov. 
Uredinia hypophyllous, scattered, sometimes in coalescent 
groups of a few sori each, round, 0.2-0.4 mm. across, dark cinna- 
mon-brown ; paraphyses peripheral, hyphoid, 10-18 by 4S~7Sl^> 
the wall thin, i /x, colorless ; urediniospores broadly ellipsoid or 
globoid, 21-25 by 28-35 /a; wall golden-brown, 1.5-2 /x thick, usu- 
ally thicker above, 5-12 /*, often somewhat thickened at hilum, 
closely verrucose, the pores indistinct, probably 3 or 4, equatorial. 
Telia resembling uredinia but darker color, chestnut-brown; 
teliospores ellipsoid, 19-26 by 37-55/^, rounded at both ends, not 
constricted at septum; wall dark chestnut-brown, uniformly 
thick, 2.5-3 /i, or slightly thicker above, very coarsely and sparsely 
verrucose, especially above ; pedicel colorless, 6-9 by 30-40 fx, 
hygroscopic near base, swelling in water to 20 fx in diameter. 
On Ehretiaceae: 
Cordia alliodora (R. & Pav.) Cham., Ponce, January, 1911, 
E. W. D. Holway. 
A rust on Cordia sp. from Peru has been described by Hen- 
nings under the name Uredo Cordiae (Hedwigia 43 : 163. 1904). 
The morphological characters are similar, but in habit it is said 
to produce gall-like swellings in the leaves and shoots resulting in 
witches-brooms, while the material from Porto Rico shows 
nothing of this sort. 
1 19. Puccinia Xanthii Schw. on Xanthium longirostre 
Wallr. (Ambrosiaceae) , San Juan, Eebruary, 1914, Britton 
and Cowell 148^; Santurce, February, 1914, J. R. Johnston

reported by Mayor (1. c., p. 581) from Haiti on same host.
