336. HARPER, Roland M. A sketch of the forest geography of New Jersey. Bull. G 

 Soc. Philadelphia 16:107-125. 3 pi. Map, Oct., 1918.— The different geographic regions 

 of the state arc mapped and briefly described with reference to soil, topography, and tree 

 growth. The trees are listed for each region and the most abundant sp< i ■■ indicated. 



In the state as a whole, the white oak is the most generally distributed tree, with the red 

 maple a close second; the pitch pine holds first place from the standpoint of numbers. — 

 P. D. Strausbaugh. 



337. Harper, Kola vi> M. The supposed southern limit of the eastern hemlock. Torreya 

 19: 19S-199. Oct., 1919. — Tsuga canadensis (L.) Carr., not previously seen further south in 

 Alabama than Winston and Marion Counties, was found by the writer on the banks of Village 

 Creek, about 3 miles southwest of Adamsville, Jefferson County, Alabama, on Sept. 2, 1919. 

 — J. C. Nelson. 



33S. Heimlich, Louis F. The trees of White County, Indiana. Proc. Indiana Acad. Sci. 

 1917: 387-471. 34 pi. 191S. — Though primarily taxonomic, this paper is of interest to plant 

 geographers, because of its maps, showing the distribution in the United States and by coun- 

 ties in Indiana of six species of Qusrcus, two species of Viburnum and Salix, Betula lutea, 

 and Malus ioensis. [See Bot. Absts. 1, Entry 798.] — II. C. Cowles. 



339. Hemsley, W. B., and others. Flora of Aldabra: with notes on the flora of the 

 neighbouring islands. Kew Bull. Misc. Inf. [London] 1919:108-153. 1919.— Aldabra, or 

 Aldabra Group, is an atoll in the Indian Ocean, 220 miles northwest of Madagascar. The 

 series contains the islands of Aldabra, Assumption, Cosmoledo, Astove, Farquhar, Providence 

 and St. Pierre situated between longitudes 45 °E. and 52°E., and between latitudes 9"S. and 

 10.5'S. The list contains 68 species of vascular plants of which 18 are endemic to Aldabra, 

 13 are limited to Aldabra and adjacent islands while 18 occur also in Madagascar and 11 are 

 found in East Africa. There is added a summary of present knowledge of the flora of Gloriosa, 

 the Amirantes group, Coetivy, Agalega, Cargados, the Laccadives, Maldives, and the Chagos 

 Archipelago. A bibliography of 26 titles completes the paper. — E. M. Wilcox. 



340. Ingham, W. Mosses and hepatics of the magnesium limestone of West Yorkshire 

 [England] [Continued]. Rev. Bryologiquc 41 : 77-82. 1914. [Issued in 1919.]— This is the 

 concluding portion of an article the first part of which appeared in 1914 (Rev. Bryologique 41: 

 53-58). The region studied is very dry during the summer but affords more favorable condi- 

 tions for the development of bryophytes during the winter. In many districts the limestone 

 is honey-combed with old and long-disused quarries, which afford excellent collecting grounds. 

 The author lists from his own collections 170 species and varieties of mosses and 24 species 

 of hepatics, giving detailed data in each case. At the close of the paper he lists 2S additional 

 species of mosses and 17 additional species of hepatics found by earlier collectors. — Alexander 

 W. Evans. 



341. Knowlton, Clarence H. An excursion to Mt. Washington, Massachusetts and the 

 Bash-Bish Falls. Rhodora 21:198-202. Nov., 1919. — An account of a one day collecting 

 expedition to the region named, giving the general topography of the region and a list of the 

 principal species collected. This list is compared with collections made by others in the same 

 region. The locality proved to be interesting mostly because of the large number of species 

 collected and the unexpected contrasts in the flora with variations in the topography and 

 situation. — James P. Poole. 



342. Knowlton, C. II., and Walter Deane. Reports on the flora of the Boston district. 

 — XXX. Rhodora 21: 7S-S3. Apr., 1919. — A continuation of the report of the Committee 

 on Local Flora of the New England Botanical Club. Reports species and their distribution 

 in the district about Boston, Massachusetts. [See also next following Entry, 343.] — James 

 P. Poole.
