is given by these authors as a synonym of Smilax glauca, which 
according to my judgment is correct. 
Smilax Spinulosa ax Extreme Form op S. Glauca. — The 
material secured recently fortunately clears up the case unless I 
misapprehend the purport of the above quotation. The “ more 
elongated leaves ” spoken of may find their counterpart in the figures 
on plate 4, and yet there can be no question thatl they belong to 
Smilax glauca. The twigs bearing them were in many cases found 
attached to the same underground sterns that bore the broad leaves. 
Even at a glance the identity of the specimens in the field could not 
be mistaken; all their characters showed that they were really 
Smilax glauca. In herbarium specimens that have been preserved 
every gradation may be seen between the extremes shown in the 
plate. These specimens also show in some cases underground stems 
that bear both leaves and twigs with leaves of the broader form. As 
a rule in the cornfields where the soil is not rich and crop-cultivation 
has been diligent the narrower leaves (on shorter stems) are com- 
mon. In richer cornfields, and in meadows, especially if quite fertile, 
the short stems are clothed with the broader leaves. Abundant 
evidence was at hand to demonstrate that this form with “more 
elongated leaves ” (S. spinulosa) is directly connected with the form 
called S. glauca by the taxonomists. Its peculiarities are doubtless 
referable to the special environment; in no case could these appar- 
ently aberrant specimens be called a specific or even varietal form.

MEETINGS OF THE BIOLOGICAL CLUB. 
October 1st, 1900, Botanical Hall. 
This evening was spent in the giving of reports on work done 
during the summer vacation. Osborn, Mills, Griggs, Tyler, Miss 
Dufour, Schaffner and Hine gave reports. Seven names were pro- 
posed for membership. 
The motion by Professor Osborn to hold the meetings of the 
current year in Biological Hall was carried. 
Hine, Morse and Miss Dufour were appointed a nominating 
committee to select officers for the year. 
November 5th, 1900. 
Members assembled in Biological Hall. President Schaffner 
called the meeting to order. Officers were elected as follows:
