Arthur: Uredinales of Porto Rico

82. Uredo paspalicola P. Henn. Hedwigia 44: 57. 1905. 
On Poaceae: 
Paspalum conjugatum de Bary, Ad juntas, Nov. 22, 4q66. 
This thin-walled, pale-spored rust, which is now reported for 
North America for the first time, has also been collected in 
Guatemala, on Paspalum Humboldtianum, Jan. ii, 1915, by E. 
W. D. Holway 64. The two collections agree closely with the 
type collection on P. conjugatum from Peru, as careful study 
shows. 
83. Uredo Dichromenae Arth. Bull. Torrey Club 33: 31. 
1906. 
On Cyperaceae: 
Dichromena ciliata Vahl, Mayagiiez, April 30, 927. 
Dichromena radicans Cham. & Schl., Guayama, April 6, 
847. 
' ,^The type specimen of the species was collected on D. ciliata, at 
Mayaguez, April, 1904, by G. P. Qinton. The form was also 
collected in Jamaica by L. M. Underwood, May, 1903, 28^2. 
The form is given for South America by Mayor in his list of 
Colombian Uredinales (Mem. Soc. Neuch. Sci. 5: 581. 1913). 
84. Uredo Fuirenae P. Henn. Hedwigia Beibl. 38: 70. 1899. 
On Cyperaceae: 
Fuirena umbellata Rottb., Santurce, Jan. 22, 253; Aguas 
Buenas, Feb. 9, 300; Mayaguez, April 30, p2o, Oct. 31, 
39531 St. Catalina, Aug. 28, 2745; Cataho, Nov. 3, 4531. 
This rust was also gathered on the same host at Bayamon, P. 
R., Jan. 1911, by E. W. D. Holway, and in Cuba, Oct. 1904, 
by Baker & Wilson 2214, and March 1907, by F. S. Earle 632. 
The species was described from Brazil on F. umbellata, and it 
has been distributed from India, also on the same host. No 
teliospores have been found in connection with it. It differs 
strongly from the uredinia of the Fuirena rust in the southern 
United States, Puccinia Fuirenae Cooke, by having two pores, 
instead of three or four as in that species, and in other characters.
