LorENZ: REPRODUCTION IN NEW ENGLAND FRULLANIAE 281 
in regard to the abundance and luxuriance of its means of vegeta- 
tive reproduction. As the adventive branches upon all species 
examined precisely resemble one another, only F. eboracensis will 
be considered in detail and figured. Material was examined from 
four states, and the Brutblatter were by far the most common 
upon the Connecticut plants, being observed but once each upon 
plants from Maine and from Waterville, N. H. These observa- 
tions and figures have been almost entirely taken from material 
growing upon Juniperus in the vicinity of Dr. Hooker’s Cabin, 
at Farmington, Conn. 
Branches with deciduous leaves are frequently produced upon 
both 9 and # plants. These may be considered as Brutblatter, 
as their method of separation is schizolytic, leaving behind one 
row of cells and the stylus. If a branch is moistened and handled 
with extreme care, the Brutblatter can be seen in position, but 
they are excessively fragile. 
hether or not the production of Brutblatter is induced by 
drought, the cause has evidently no connection with the time of 
year, as plants collected in January and May from neighboring 
stations bore equally good Brutblatter. While Brutblatter are 
€qually common upon 2 and ¢ plants, the writer has not yet 
observed any upon plants with mature capsules, although thick- 
walled cells are occasional upon perichaetial bracts as well as 
ai underleaves, Neither were they observed upon perigonial 
racts,

The leaves themselves often develop rhizoids, by the projection 
and lengthening of marginal cells, thus being prepared to get a 
old wherever the leaves happen to be shed. (Fic. 1, A.) 
The gemmalike masses of cells are developed from the margin
