paraphyses peripheral, numerous, incurved, clavate, stout, 10-12 
by 19-23 /X, the wall colorless, thin, 0.5 /x, somewhat thickened on 
the outer curved part, 1.5-2 /x, smooth; urediniospores obovoid, 
16-23 by 25-29 jix; wall golden-yellow, thin, i /x, moderately ver- 
rucose-echinulate, the pores obscure. 
On Rubiaceae: 
Sabicea aspera Aubl., Mayagiiez, May i, 104^. 
This distinctive rust with its conspicuous paraphyses is evi- 
dently not the same as Uredo Cephalanthi Arth., which is without 
paraphyses. There appears to be no other form known that is 
at all closely related. 
95. Uredo proximella sp. nov. 
Uredinia chiefly hypophyllous, crowded in groups 2-4 mm. 
across, bullate, roundish or irregular, large, 0.3-0.9 mm. across, 
tardily naked, cinnamon-brown, pulverulent, ruptured epidermis 
conspicuous as a partial membranous covering; urediniospores 
broadly ellipsoid or obovoid, 18-20 by 19-24 /x; wall cinnamon- 
brown, thin, 1-1.5/X, closely and finely echinulate, the pores rather 
indistinct, 4-6, scattered. 
On Cichoriaceae : 
Lactuca intyhacea Jacq., Sabana Grande, March 30, ^18. 
In the characters of both sori and spores this species bears con- 
siderable resemblance to the uredinia of Puccinia hemisphaerica 
(Peck) Ellis & Ev. It has been detected on specimens in the 
phanerogamic collection of the N. Y. Bot. Garden from St. 
Domingo, March, 1913, Rose, Eitch & Russell 4015, and from 
Cuba, March, 1909, N. L. Britton 2161. 
96. Uredo biocellata Arth. Bull. Torrey Club 33: 517. 1906. 
On Carduaceae; 
Pluchea odorata (L.) Cass., Ponce, Dec. 4, 55PJ; Vega 
Baja, Feb. 22, jdoa. 
Pluchea purpurascens (Sw.) DC., Santurce, May 21, 
jypp; Cabo Rojo, Sept. 28, 3186; Mona Island, Dec. 20, 
21, 6198. 
The species was also found in the phanerogamic herbarium of 
the N. Y. Bot. Garden on P. odorata, collected at Guanica, P. R., 
Jan., 1899, by C. F. Millspaugh 7/3.
