Professor Schrenk, remarked on Professor Francis Darwin's 
recent paper on the bloom of leaves and the distribution of the 
stomata published in Vol. xxii. of the Journal of the Linnzan 
Society of London. A discussion of stomata and. trichomes 
ensued in which several members participated. 
Dr. Britton exhibited specimens of Lathyrus maritimus, 
Bigel., collected by Rev. Mr. Lighthipe at Ocean Beach, N. J.; 
this appears to be the most southern station known for the plant 
on the Atlantic Coast. He also showed a large form or variety 
of Bidens cernua, L, from the tidal streams at Red Bank, N. J. 
Professor Schrenk stated that at the locality near St. Ronan’s Well, 
Long Island, where ZL. maritimus was so abundant, it is about ex- 
terminated. 
PROCEEDINGS OF THE HISTOLOGIC AND CRYPTOGAMIC 
SECTION, January 25th.—Professor Schrenk showed a series of 
” leaf-sections of Sci//a maritima both stained and unstained ; also 
a very interesting longitudinal section of the rhizome of Arzsto- 
lochia Serpentaria showing a dotted duct with a sac-like protru- 
sion of an adjacent parenchyma cell pushed into the duct-cavity 
and filled with starch grains. He also announced the discovery 
of a fourth kind of glandular hair on the leaves of tobacco show- 
ing specimens of variable and irregular branching, found especially 
on young leaves. J. I. Northrup exhibited crystals of calcium 
oxalate in the petiole of Hoya and sclerotic endodermis in Peper- 
omia argyrea. N.L. Britton showed stomata on fossil creta- 
ceous leaves from the clay beds at Perth Amboy, and Mrs. 
Britton prothallia of Onoclea sensibilis in different stages.
