PHYCOLOGICAL NOTES OF THE LATE ISAAC 
HOLDEN,— I. | 
Edited by F. S. COLLINS. 
IN the notice of Mr. Isaac Holden, RHopoRa, Vol. V, p. 219, 
mention was made of the careful record it was his custom to make 
of his collecting, with a view of publication as soon as a sufficiently 
complete list of the flora of the region near Bridgeport, Connecticut, 
could be made. At the time of his death nothing had been done 
towards publication, but now by the courtesy of Mr. Holden's family, 
his note books “have been entrusted to the writer, who hopes to be 
able to make their contents available to the readers of RHODORA. 
Mr. Holden's numbered notes begin in 189o; the first 11 numbers 
referring to forms of the genus Batrachospermum, to which he was then 
giving special attention; each number covering specimens of a par- 
ticular type or station, but of various dates; with No. r2 begins the 
system, afterwards followed, of using a number only for one date and 
for one form, but including an indefinite number of specimens of any 
one date and place, supposed to be identical. No. r2, the first under 
this plan, is Cladophora Rudolphiana Ag., May 18, 1890; the last is 
No. 1553, Laminaria AgardAii Kjellman, May 10, 1903, about six 
weeks before Mr. Holden's death. While absolute dependence can 
be placed in all of these records, no deduction should be drawn from 
the absence or the infrequence of record of any species; the record 
is one of specimens collected, not of plants observed ; common forms, 
in regard to which no question was likely to occur, were passed by 
without record ; for a fuller list of the marine algae of the Bridgeport 
region see Lists of New England Plants, V, Marine Algae, RHODORA, 
Vol. II, p. 41; the Connecticut column rests almost entirely on Mr. 
Holden's collections, and includes everything found by him up to the 
publication of the list; as regards fresh water algae, however, the 
present paper includes practically all Mr. Holden's observations.
