large subgenera those of the series. This is a great improve-

in our previous text-books.

Proceedings of the Club. 
The regular monthly meeting of the Club was held at Col- 
umbia College June 8th, 1886. Dr. G. D. Holsten and W. A. 
McCorn were elected active members, and Ensign W. E. Safford, 
U.S.N., and E. C. Smith, of Augusta, Maine, corresponding mem- 
bers. Dr. Newberry exhibited a new, pear-shaped variety of 
orange, recently received in the New York markets from Southern 
California, and remarked on the progress of orange culture in that 
region. Mrs. Britton distributed specimens of Aspidium spinu- 
losum, Willd., var. dilatatum, Eaton, and A. cristatum, Swartz, in 
several forms, some of them approaching var. C/intonianum, 
Eaton, from Boonton, New Jersey, and exhibited A/yssum in- 
canum, L., from Dedham, Massachusetts, where, in July, 1882, 
it was abundant along the railroad and apparently naturalized; it 
is native of Central Europe. Mr. P. H. Dudley read some further 
notes on the formation of ducts in chestnut wood. Mr. Schrenk 
remarked on the phenomena of certain leaves of shedding water, 
especially those of /mpatiens, which have a perfectly smooth epi- 
dermis, and attributed it to the abundance of cutine. Those of 
the Snowberry have a similar power. Dr. Newberry called atten- 
tion to a similar action by the velvety leaves of Abutilon Avicenne. 
Dr. Britton exhibited specimens of the Dusty Miller, Senecio Cine- 
raria, DC., collected by Prof. E. H. Day on the sea heach of 
Monmouth County, New Jersey, and remarked that it had now 
been noticed at several places on the beaches in the vicinity of 
New York, and might well be regarded as adventive; also Carex 
ptychocarpa, Steud., from Lake Hopatcong. Ensign W. E. Saf- 
ford, U. S. N., read the announced paper of the evening, entitled 
“A comparison of the Flora of Ross County, Ohio, with that of 
Southern New England.” 
The Club then adjourned until the second Tuesday in October,
