The nomenclature used is that of Britton & Brown’s Illustrated 
Flora, second edition, the sequence of species following strictly 
the author’s phyletic classification. With reference to Tipularia 
unifolia we would suggest that reference should have been made 
to its occurrence in Ashtabula County as discovered in 1911 by 
R. J. Sim. (Torreya 12:107-110. May, 1912. 
Bulletin 3, “A Botanical Survey of the Sugar Grove Region, ” 
by Prof. Robert F. Griggs, is an excellent treatment of the eco¬ 
logical relations of the vegetation of the “Sugar Grove region,” 
a rolling upland cut up with numerous deep ravines, and extending 
in a north and south direction for about twenty miles in Fairfield 
and Hocking counties, south central Ohio. The region is imme¬ 
diately south of the glaciated region and may be considered as 
an outlier of the Appalachian Plateau. 
To one familiar with the vegetation of the Appalachian 
Plateau in western Pennsylvania the Botanical Survey of the 
Sugar Grove Region reads almost like a survey of some of the 
quite similar areas to be found in the first-named region. The 
less important place occupied in the Sugar Grove Region by 
Rhododendron, Kalmia latifolia, Castanea and Robinia Pseudacacia 
and the absence of Pinus Strobus and Azalea nudiflora , is balanced 
by the presence of Hypericum Drummondii, Napaea dioica and the 
greater prominence of Oxydendrum, Acer Negundo, Sullivantia, 
Quercus macrocarpa, Dodecatheon, Diospyros, etc. Altogether the 
associations could be applied almost as well in the one region as 
in the other, but with the eastern species thinning out westward 
and a number of more northern species reaching into the Sugar 
Grove Region. Prof. Griggs is to be complimented upon the 
excellent manner in which he has accomplished this survey. It is 
to be regretted very much, however, that the proof-reading was 
not more carefully done. In a rather causal examination errors 
were noted in the scientific names to the number of sixty-six; on 
page 280, six out of twenty-seven names in one list being incor¬ 
rectly spelled. We sincerely hope that more attention may be 
paid to the proof-reading in the future numbers of the survey, 
the present numbers being otherwise printed in a highly satis¬ 
factory manner.
