THE PLANT WORLD. 
had been made during the day for F. Darlingtonii but without 
success. Fraxinus Biltmoreana found this season by us near 
Trenton, N. J., was not noticed here, though it had been found 
by Dr. John K. Small in this locality about ten years ago. Its 
fruit differs from that of F. Americana or white ash by its shorter 
body and longer and broader wing, and by its velvety pubescent 
foliage. 
Mr. Crawford described the work of the day by calling especial 
attention to the flourishing forms of Asplenium montamim on a 
large rock above the hotel where it had been practically un¬ 
molested for twelve years. It is the most generally distributed 
of the small rock-inhabiting ferns in the valley. 
Filix bulbifera was luxuriant on a few rocks below the house; 
nearby were noticed for the first time in York County a goodly 
number of young plants of Passidora lutea. 
The late Dr. Thomas C. Porter had reported this from Tuc- 
quan, just above this place, also at Safe Harbor, which is perhaps 
its most northerly limit. 
A few scrawny fronds of Pellaea afropurpurea were also seen 
on a river rock along shore, being a rarity also in this neighbor¬ 
hood with no limestone to flourish upon. 
Messrs. Samuel Van Pelt and Albrecht Jahn made mention of 
the large colonies noticed in the afternoon stroll of Synosma 
suaveolens and Silene alba and smaller ones of Mesadenia reni- 
formis and M. atriplicifolia, also a few plants of a climbing vine 
with strongly white striped leaves which suggested Gonolobus 
laevis Michx., a rare plant indeed for this region. 
Rhododendron maximum was very abundant on the sheltered 
rocks and gorges in the hillsides, though flowering very sparingly 
in the latter situations. 
Carex Caroliniana was a sparsely distributed sedge but with 
very ripe fruit. 
The following day was spent in the vicinity of the “ Slab ” and 
“ Broad Water,” two miles south, where the canal was formed by 
appropriating a rocky and picturesque channel of the river and 
heavily walling it up, but which the Susquehanna has since re-
