NEW NAMES FOR SPECIES OF PHANEROGAMS 



By J. C. Arthur 



While studying the Uredinales and hsting their hosts for pre- 

 sentation in the North American Flora a number of phanero- 

 gamic species have been encountered, which have not been trans- 

 ferred, so far as the writer can ascertain, to the genera under 

 which related species are being listed. As it is desirable to have 

 these transfers made for the sake of uniformity, and as no one 

 else seems desirous of making them at this time, they are here 

 recorded. The advice of Mrs. x'\gnes Chase, Mr. Percy Wilson 

 and Dr. F. W. Pennell has been followed, although the writer 

 is to be held responsible for any errors that may occur. 



Senites Hartwegi (Fourn.) nom. nov. {Zeugites Hartwegi Fourn. 

 Mex. PI. 121. 1886). A grass of Central America, and known 

 from Mexico by the type specimen only, Hartweg ^6p. It bears 

 Uredo Zeiigitis Arth. & Holw. from San Rafael, Guatemala, 

 7000 feet alt. (Am. Jour. Bot. 5: 538. 191 8). 



Sanguinale pruriens (Trin.) nom. nov. (Panicum pruriensTr'm. 

 Gram. Pan. 77. 1826). A grass of Hawaii, that has been re- 

 ferred to Panicum sanguinale. Professor A. S. Hitchcock holds 

 it to be clearly distinct. He observed in the field that the racemes 

 are erect, not spreading as in P. sanguinale, and Mrs. Chase has 

 found that the first glume is wanting and the second very minute. 

 It bears Puccinia oahuensis Ellis & Ev., which was only known 

 from the type collection, obtained on the slopes of Makiki, Is- 

 land of Oahu, by A. A. Heller, in 1895, until it was detected by 

 Mrs. Chase on two collections of the grass made near Honolulu 

 by Prof. Hitchcock, one along a ditch, June 16, 1916, no. 13735, 

 and the other as a weed in shady places. Halfway House. Mt. 

 Tautalus, June 24, 1916, no. 13862. Puccinia oahuensis is 

 scarcely distinguishable morphologically from P. suhstriata Ellis 

 «& Earth. 



Nymphoides Grayanam (Griseb.) nom. nov. {Limnanthemum 

 Grayanum Griseb. Cat. PI. Cub. 181. 1866). A West Indian 

 aquatic plant in the family Menyanthaceae, on which aecia of 

 Puccinia Scirpi DC. were found in C\iba by Charles Wright in
