CHRISTENSEN? has begun the publication of an Index Filicum, which is 
intended to do for ferns what the Index Kewensis does for seed-plants. The 
book will contain a systematic enumeration of the genera, based upon ENGLER 
and Pranti’s Pflanzenjamilien; an alphabetical enumeration of species and 
synonyms, which will include all names and combinations of names published 
from 1753 to 1905 and also names of garden ferns; and an alphabetical catalogue 
of literature containing critical notes and descriptions of new genera and species. 
The work will be complete in eleven or twelve parts, and the entire manuscript 
is ready for printing, awaiting only a sufficient subscription. The first fascicle, 
just issued, begins the alphabetical list of genera and species, closing with Aspi- 
dium.—J. M. C. 
Merritt+ has attacked the species described in BLANCO’s monumental 
Flora de Filipinas, recognizing that they must be identified and made available 
so far as possible. He has brought together these identifications in a conveniently 
arranged bulletin, calling special attention to the species that are yet to be identi- 
fied. To give some idea of the results attained by this absolutely isolated worker, 
it may be said that in the two editions of the Flora (1837 and 1845) BLANC 
described 1127 species and varieties; about 623 of these were proposed as new, 
and 504 identified with species of other authors, 219 of them correctly and 285 
incorrectly. A large proportion of the new species remain unknown, and only 
go are known to be valid.—J. M. C 
Hircucocxs has published an elaborately illustrated synopsis of the North 
American species of Agrostis, recognizing twenty-seven species and describing 
three. as new. It is announced as the intention of the department to publish 
occasional monographs of the larger genera of grasses.—J. M. C. a 
Husvor® has published the first part of an illustrated synopsis of the Coe 
aceae of France, Switzerland, and Belgium. This part contains Elyna, Kobrestay 
and Carex. The important characters of each one of the 123 species of aie 
are illustrated —J.M.C.  - on.
