such einer Naturgeschichte von Chili, 17.86, p. 272), overlooking the fact 

 that this latter name originated with Molina, it appearing in the first 

 (1782) edition of his 'Saggio sulla Storia Natural e del Chili,' p. :U2, as 

 Lepus mscacia. The name of the Yiscacha should therefore be Vizi-ttcia 

 rixcncin (Molina). The authority for the specific name is hence Molina 

 and not Brandis, and the name itself takes the form vwcaria instead of 

 viscaccica. J. A. Allen. 



A new Helianthus from Florida.*

Annual, rather freely branching, about one meter in height; stem

 gradually thinning below to a few scattered hairs; lower cauline leaves 

 lanceolate, acuminate, 1.5 dm. long, tapering below to a short margined 

 petiole, the margins remotely denticulate, hispid with short bristly 

 hairs; blade with a prominent central nerve and two laterals springing 

 from some distance above the base, both surfaces glabrous except along 

 the primary nerve beneath; heads 5 to 6 cm. in diameter, the rays about

Type in the United States National Herbarium, Smithsonian Institu 

 tion, (sheets Nos. 370175 and 370176) collected on shelly land between 

 Lake Beresford and the St. Johns River, Volusia County, Florida, .July 

 12, 1900, by A. H. Curtiss, The collector observes that the plant is ten 

 der and rather succulent, an unusual character among the species of 

 Helianthus. 



The new species had been previously collected by A. P. Garber in 

 Levy and Manatee Counties in 1877. Mr. Merritt L. Fernald, of the 

 Gray Herbarium, who had independently reached the conclusion that 

 the plant was undescribed, courteously placed at my disposal the notes 

 he had prepared, from which I quote the following: "Mr. Garber's 

 plant was included by Dr. Gray in his If. Floridamw, but it is very dis 

 tinct from that perennial species, which must rest upon Palmer's plant 

 No. 283 of the 1874 collection, first cited by Dr. Gray, a plant well 

 matched by other specimens from Chapman and Curtiss, No. 1437."- 

 Charles Louis Pollard.
