Additions to and Corkections op the "Catalogue op Forest Trees of the 

 United States." — Since the publication of tlie "Catalogue of Forest Trees of the 

 Uuitetl States," in 1876, several omissions and errors have been noted, whicli I wish to 

 make the subject of a few notes. 



The Anona, No. \) of the Catalogue, has been determined as A. glabra, L. See Dr. 

 Chapm in in Botanical Gazette, for January, 18T8. 



Several trees that had been credited to Florida were omitted in the Catalogue from 

 an opinion that they had not been verified in many years and might have been ad- 

 mitted imi^roperly. Dr. Chapman stated tliat Sicietenin Mahogani L, was admitted into 

 the Flora on the ground of some pods found on the coast by Dr. Leitner. Specimens 

 of this tree liave recently been collected by Dr. Garber at Lignum Vitte Key, west oast 

 of Florida. Hibiscus tiliacens, L., was also collected by him at Miami, Florida. 

 Whether it is there indigenous or only naturalized we are not informed. It is tiie onlj' 

 Malvaceous tree within our limits. At the same place Dr. Garber also collected Srutia 

 Hdi'cinnphiila, Bong , and Eri/tltriiia fj orallodendron, L., the latter with a trunli 17 

 inches in circumference. At Lignum Vitae Key he also collected Drypetes coriacea, 

 growing from 20 to 40 feet high. On the Keys opposite Sarasola ne found a species of 

 Olive 15 to 20 feet high, growing in the wild hummocks, where, he says, it may have 

 been introduced, but is now well established. Tfrmi/ial/a Ciitfqypa, L , and Psidium buxi- 

 foliuin, Nutt., are described as Florida trees in Nutlall's addition to Michaux's Sylva. 



Dr. Garber writes us that Dr. Chapman now thinks that Ulmus Floridana of the 

 Southern Flora is only a smooth form of U. Aiiiericniia with the flowers more racemose. 

 We are not in possession of any more information respecting Fraxiinis Curtissi, No. 

 211 of the Catalogue. Dr. Gray thinks it may be a form of F. Americana. Since the 

 publication of the Catalogue Prof. Watson has established a Fopulus Fremontii,ii pop- 

 lar of New Mexico and Arizona, which had previously been regarded as a form of 

 P. monilifera. 



No. 272 of the Catalogue (Quercus Priniix, var., monticola) must be omitted, as Dr. 

 Engelmann ("The Oaks of the United States," in Trans. St. Louis Acad. Sciences) has 

 shown it to be a typical sjjecies, and very different from any others of the ,White Oak 

 group, while No. 373 he describes as a distinct species under the name of Q. Mulden- 

 bergii=Q, Castanea, Muhl. lie considers Q. prinoides, Willd., a sub-species of this, 

 the connection of forms being found in Kansas and Nebraska, where " it bears abund- 

 antly when only 1-3, or up to 30 feet high." 



Dr. Engelmann's new species, Q. tomeiiUdla , from the Island of Guadaloupe, off the 

 coast of California, should be added to the Catalogue. / 



No. 343 of the Catalogue, /•'ih(/.s resinosa. Ait , grows 100 to 150 feet high in the 

 Michigan pine region, according to Prof. C. E. Bessey, of the Iowa Ag. College. 



No. 364 It now appears, according to Dr. Engelmann, that the specimens grow- 

 ing east of the Sierras, which have iisually been referred to as Finns Balfouriana, Jefi., 

 are onlv a form of P. aristcta, Eng. Specimens of the true F. Balfou-.iana we have 

 since received from the Sierras of California and Nevada, wliich are identical with the 

 original Oregon specimens on which the species are founded.
