IOO — 
This entire subject is one of the greatest importance to the systematic 
bryologist and the preceding suggestions only touch upon its fringe. Had 
its importance been recognized by earlier writers not only would the Cleisto - 
parpi never have been treated as a separate group, but Grimmia and Ortho- 
trichum would never have been put in the same family or Homalothecium, 
Pylaisia , Orthothecium and Entodon been closely associated. 
Sometime later I hope to be able to add to the above suggestions and to 
give an extensive list of species confirming these suggestions, together with 
such exceptions as I can find.

ASA GRAY. 
November 18, 1810 — January 30, 1885. 
The portrait herewith presented marks the recent publication of the 
seventh edition of the long familiar “ Gray’s New Manual of Botany.” This 
volume is illustrated, some groups more fully than others, and rearranged to 
follow in large part that of Engler and Prantl, but it is still in all essentials 
the beloved book of our youthful days. It is edited by Benjamin Lincoln 
Robinson, Asa Gray Professor of Systematic Botany at Harvard University, 
and Merritt Lyndon Fernald, Assistant Professor in the same University, 
and published by the American Book Co. 
We had hoped to have a biographical sketch to offer at this time but our 
space is full and we can only refer our readers to the interesting account 
given by Walter Deane of the life and death of this “ venerable Priest” of 
Botany, in the Bulletin of the Torrey Botanical Club, Vol. XV., No. 3, 
March, 1888, from which number our plate is reproduced. 
A PRELIMINARY LIST OF HEPATICS FOUND IN THE VICINITY 
OF BALTIMORE. 
Charles C. Plitt. 
Ricciaceae. 
1. Riccia fluitans L. (terrestrial form). 
In early spring, after the snows and ice have disappeared, and the 
streams are beginning to subside, this pretty little hepatic will be found 
appearing in great numbers upon areas of the alluvial soil along the 
river, sometimes, too, extending into the cultivated fields, some distance 
from its banks. 
Marchantiaceae. 
2. Rehoulia hemisphaerica (L.) Raddi. 
This is a fairly common hepatic in our limestone regions. I had become 
so accustomed to seeing it only in such regions, that I' was very much 
surprised to find it once in a shady spot along a roadside in our Coastal 
Plain.
