Tlie Ameriain Naturalist, February and IVIarch. — In the latter number we have two 

 botanical articles: "The Transpiration of Plants," by J. M. Anders, and "Rambles of a 

 Botanist in New Mexico," l^y E. L. Greene. Both arc interesting and deserve a fuller 

 notice than our crowded pages permit us to give. 



A Synopsis of the American Firs, by Dr. Geo. Eugelmaun. — Dr Engelmaun takes 

 up one difficult genus after another, and by the most patient and conscientious work 

 brings order out of confusion. The species of Abies have long been contused, but 

 now the sub-divisions of the genus are based upon leaf-structure, principally the two 

 resin ducts, with greater certainty than on the length of the bracts, as was formerly 

 done. "It is a most interesting as well as significant fact that while the anatomical 

 structure of the leaves of higher organized plants shows considerable uniformity, so 

 that it rarely can be made available for diagnostic purposes, the conifers exhibit such 

 a wonderful variety of leaf structure (appi-oaching thereby the lowest orders of vascu- 

 lar plants), that often a single leaf is sufficient to recognize the genus, and often the 

 species, even when the ordinary characters may leave us in doubt." Nine species are 

 enumerated, viz: A. Fraseri, Lindl., A. balsdviea, Marshall, A. subalpi}ia,'Enge\m., with 

 var.fallax, A. grandis, Lindl., and var. densifolia, A. concolor, Lindl., A. religiosa, 

 Schlecht., A. brncteaia, Nutt., A. nobilis, Lindl., and A. magnifica, Murray. 



Ferns of North Ainerien. by Prof. D. C. Eaton, Parts II and III.— The second and 

 third parts ot this splendid work are fullj' equal, if not superior in fine workmanshi]) 

 to the first, and Mr. S. E. Casino is to be congratulated upon its fine typographical 

 appearance. In Part II there are three plates, containing seven species, and descrip- 

 tions of six. The species are As-plenium ebeneian, Ait., A ebenoides, R. R. Scott, Bo- 

 tri/ehlum lunaria, Swarlz, B, lanceoldt tan, Kngsivom., B. boreale, Milde, Cheilanihes Jcmii- 

 ginosa, Nutt., and 0. Californica, Mett. The specimens of Asj)leniurn ebeneinn found in 

 considerable abundance in this county are much more luxuriant in habit than the one 

 figured, but not more so than is provided for in tho text. The figure of A. cbeno ides 

 shows well its supposed hybrid character, the long, tapering, proliferous tip much re- 

 sembling Camp)tosorus rhizophyllus, and its other features like A. ebeneum. Prof. Eaton 

 recommends the attemjU to produce this plant by artificial hybridizing, and thus estab- 

 lish its true hybrid character or not. Botrychium boreale is figured and described 

 although collected but once in North America and that by Chamisso, sixty years ago 

 in Unalaska. Its appearance in this work, however, may aid in its re-discovery, In 

 Part III five species are figured, viz: Aspidiiim Nm-ehoracense^ Swartz, Camptosorus 

 rhizophyllus. Link, Aspletiiump>innatifidmn, Nutt., Noiholcena Fendleri, Kunze, and N. 

 dealbata, Kunze. 



Catalogue of the Phmiogamoiis and Vascular Cryj)togamous Plants found growing 

 wild in Jetterson county, Ind. This catalogue is compiled by Mr. Chas. R. Barnes, and 

 M)'. Jno. F. Baird adds a .«hort list of plants growing in Clark county, not as yei found 

 in Jcfierson. The Jetterson county catalogue numbers 912 species through the Vascular 

 cryptogamia, and hence forms a valuable check list. Anyone desiring copies of it can 

 be supplied by writing to Mr Chas. R. Barnes, Madison, Ind.
