Ivelating to species of this country, we should mention, in the first 

 place, Gray's Contributions to North American Botany, which consists of 

 two parts. Thefirstgivestheresultsof his studies of ylsfer and SoUdago 

 in tlie older herbaria; the second, entitled Novitice Arizonicw, describes 

 principally Gamopetalw from Arizona and adjacent regions, including 

 se\-eral new genera. In a note two new gentians are described by 

 Engelmann. In the Bot. Gazette, Professor Gray describes a new spe- 

 cies, ParisheUa Californica, and at the meeting of the Am. Ass. Adv. 

 Sci., at Montreal, he delivered an address on the history of the study of 

 botany in this country. In the Proc. Am. Acad, of Boston, Watson 

 has published a list of plants from Southwestern Texas and ISTorthern 

 Mexico, consisting principally of Polypetakc collected by Dr. B. Palmer 

 in 1879-'80, and a "Description of New Species of Plants," chiefly from 

 the Western Territories. Several important papers by Dr. Engelmann 

 have appeared in different journals. In the Botanical Gazette are " Notes 

 on Western Conifers;" "Additions to the North American Flora," in- 

 cluding new species of Stellaria, Campanula, &c.; the "Black-fruited 

 Gratjegi," with a description of a new species, C. hradiyacantha; and 

 "Some Notes on Yucca." In the Gardenerh Chronicle, Engelmann has 

 some notes on Picea Bngelmanni and Pinns pungens. New grasses have 

 been described by Vasey, spec'es of Poa and Stipa from California, in 

 Bot, Gaz. : and species from Arizona and California, described in Torr. 

 Bull, by F. L. Scribner. Dr. Parry has papers on a new rose, E. minuti- 

 /o/ia, and on the "Fruits of Cncurbita,''^ both in Torr Bulletin. M.S. 

 Bebb has " Notes on Salix Sitchensis and its Affinities," and " Salixflave- 

 scens var. Scouleriana,^^ both in Bot. Gazette. " New Species of Com- 

 positoe" and "New Western Plants" by E. L. Greene, and "New Cali- 

 fornia Plants " by M. E. Jones, have appeared in the Torr. Bulletin. 

 The Bulletin also contains "Notes on Hybrid Oaks" by Professor 

 JMeehan and N. L. Britton ; "Notes on the Trees of the Southwest"

 Bailey; and a paper on the "Migration of Weeds" by H. W. Kavenel. 

 The " Native Trees of the Lower Wabash " are described by Robert 

 Bidgway in the Proc. National Museum. The Flora Pcoriana, by Fred. 

 Brendel, is an account of the plants near Peoria, 111., published in Ger- 

 man at Buda-Pesth. 



Except as continuations of previous works, no very elaborate books 

 have appeared this year on exotic floras. Vol. v of Boissier's Flora 

 Orieyitalis includes monocotyledons. Hooker's Flora of India has been 

 continued, and also the Iconcs Plantarum, which has reached the 4th
