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

 ,f)lace, Gray's Contributions to North American Botany, which consists of 

 two parts. The first gives the results of his studies of Aster and Solidago 

 in the older herbaria; the second, entitled N'ovitiw Arizonicw, describes 

 ipriucipally Oamopetalce from Arizona and adjacent regions, including 

 several new genera. In a note two new gentians are described by 

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

 ■cies, Farishella 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 Froc. Am. Acad, of Boston, Watson 

 has published a list of plants from Southwestern Texas and Northern 

 Mexico, consisting principally of Poli/petalm collected by Dr. E. Palmer 

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

 the Western Territories. Several important papers by Dr. Engelmann 

 liave appeared in difierent 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 

 •Cratjegi," with a description of a new species, G. hrachyacantha; and 

 "Some Notes on Yucca." In the Gardener^s Chronicle, Engelmann has 

 'some notes on Ficea, Engelmanni and Finus pun gens. New grasses have 

 been described by Vasey, spec'es of Foa 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, B. minuti- 

 folia, and on the " Fruits of Cucurhita ,''^ both in Torr Bulletin. M. S. 

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

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

 positse" 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 

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

 byH. S. Kusby; "Notes on the White Mountain Flora" by W. W. 

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

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

 Eidgway in the Froc. National Museum. The Flora Feoriana, by Fred. 

 Brendel, is an account of the i^lants 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 

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

 continued, and also the Icones Flantarum, which has reached the 4:th
