found at the summit of the stem; and in connection with the young 
strobili the petioles of old leaves and peduncles of old strobili were in 
situ, so that the relative positions of the organs could be ascertained. 
A stem received July 5 showed the remnant of an old peduncle, 
a young ovulate strobilus, and about 5"™™ from this a circle of leaves 
surrounding a growing point (fig. 1). Another ovulate plant of the same 
age had a young strobilus, but apparently no vegetative point ; however, 
on sectioning this young strobilus and the tissue at its base, the vegeta- 
tive point was disclosed very close to the strobilus, with a few leaves 
surrounding it. This growing point with its leaves was enclosed 
within the scale leaves, which in turn surrounded the strobilus (fig. 2). 
Two other ovulate plants when sectioned showed each a smaller 
strobilus at the base of the larger one, and between them the vegetative 
point like a small protuberance surrounded by rudimentary leaves. 
This whole group was enclosed within a circle of leaves which formed 
a hollow cone (jig. 3). 
One of the smallest staminate cones, received June 14, had a 
vegetative point at its base, with rudimentary leaves (jig. 4). In 
material received July 5 three staminate cones were found upon one 
plant (jig. 5). These were of different sizes and the vegetative point 
was situated at the base of the smallest cone. Each strobilus of 
the group had apparently been the terminal one, and had been pushed 
aside by the newer one in itsdevelopment. The strobili would thus be 
in lateral positions at the conclusion of the year’s production of cones. 
There was no stunting of any of the leaves of the vegetative point, and ~ 
the point was small in every case and clearly meristematic, as shown 
by the staining. Later in the season, where there were several 
staminate cones, they were nearly of the same size and apparently 
of about the same stage in development, so that they might easily 
be supposed to be of the same age and to result from a forking of 
the stem, as SAcus thought. The axes of the sympodium in such 
cases are shortened, so that the branches stand almost upon a level 
(fig. 6). Good figures are shown by WIELAND (21). 
The ovulate strobili are generally formed singly, one a year from 
the vegetative point. The staminate strobili develop more rapidly 
and from a succession of vegetative points, but they reach maturity at 
about the sme time. The two or three cases in which more than one
