The paper is an excellent contribution toward the solution of the problem 

 of the formation of the fruit-bodies of higher fungi by the correlated growth of 

 apparently independent elements. The problem has been attacked from^ a new

Coastal plain vegetation.— R, :M. Harper's studies of the vegetation of the 

 coastal plain (Box. G^azette 40:392, 393- i9<^5) continue to appear in vanous 

 journals. His most pretentious work, consisting of a phytogeographical sketc 

 of the Altamaha Grit region of the coastal plain of Georgia, has been recently 

 reviewed in this journal (43: 225. 1907). This admirable paper should be read 

 by aU ecologists. The fulness of citation in the bibliography accompanying 

 this work is most excellent, and may well be copied by authors generally; ^ 

 addition to the exact citation of the original paper, citation is made of review^ 

 of the paper cited, and a short appreciation of the article is given. In the Bui . 

 Torr. BoU Club (32:451-467. 1905) appear accounts of phytogeographical 

 explorations m the coastal plain of Georgia in 1904, in which are noted mterest- 

 ing patches of mesophytic forests rather apart from the region where such fores 

 dominate; also a peculiar case of a pine barren similarly isolated from the grea 

 pine barren region. In the same journal are accounts of new and notewort } 

 plants from the coastal plain of Georgia (33:229-245- 1906), notes on the dis- 

 tribution of some Alabama plants (33:523-536. 1906), and an account of a mi 

 su mm er journey through the CaroUnas and Virginia (54:35i'"377- i9^7)- 

 the latter paper mention is made of the remarkable flatness of the region, an^^ 

 a type of plant society, locally known as **pocosins," is described; a "pocobin 

 is a sort of heathlike swampy thicket of evergreen shrubs and scattered pi^ 

 especially characteristic of the Carolinas. ^ , 



In Torreya are several short articles, one of which gives a statistical met^o 

 for comparing the ages of different floras (5:207-210. 1905), based on the 1 

 that monocot\ls develop dominantly in a region before dicotyls; the average a 

 number of local lists in glaciated and coastal regions ^ves about 30 per cent. 

 monocot}-ls; while simUar lists in older regions have about 24 per cent, of mono- 

 cot}Is. In tiie Altamaha Grit region of Georgia, the relatively young pine '^^"- 

 rens have 44 per cent, of monocotyls; while there are but 13 per cent. 11 

 climax forests of the region. Other papers in the same journal give short stu les 

 in the North Carolina coastal plain (6:41-45. 1906), the Paleozoic ^S^^^^ 

 Alabama, in which some new coastal plain plants are foimd (6:iii-ii7- ^9^^' 

 southeastern Mississippi and eastern Louisima (6: 197-205. 1906), the Altama^ 

 Grit re^on of Georgia, gi\ing additional notes on this region (6:241-246- 19^ ^' 

 and a Long Island cedar (i.e.,Chamaecyparis) swamp (7:198-200. 1907).
