of Darby-Road botanists, composed of William Hob- 
son, William DeHart, Robert Kilvington, Thomas 
Meehan, and others, but the ‘‘find” was made by Mr. 
Scott, who noted the dual character of the plant in his 
first report of it to the Pennsylvania Horticultural 
Society, which later appeared in the columns of the 
Gardeners’ Monthly. From the date of its first report 
until now, and in spite of experiments and demonstra- 
tions by Miss Slosson and others, the plant yet con- 
tinues a “‘bone of contention,’ and I know not a better 
subject to start an argument among botanists than to 
assert that it is, or is not, a hybrid. As I wish not, at 
this time, to start a discussion, I shall conclude by 
stating that the ‘“‘Fern Flora’’ assigned me is but a 
small part of the wonders of the region, and I trust 
that, when again our members meet in Philadelphia, a 
day will be reserved and that you will ask me to guide 
you through our wondrous Wissahickon.

A Review: W. R. Maxon. THe NortH AMERICAN 
SPECIES OF PSILOGRAMME.! 
Psilogramme is a genus of tropical ferns belonging to 
the tribe Pteridiw, and is one of the groups formerly 
included under the omnibus generic name of Gymnogram- 
ma. In the present paper eight species are dealt with, 
of which three are new, all from Mexico or Central 
America. Besides these eight there are two species 
which have been called Psilogramme but which are here 
considered as of doubtful relationship to the others.
