LIST OF FERNS COLLECTED ON THE MOUNTAINS NEAR THE CITY OF 
CHIHUAHUA, MEXICO, DURING THE SEASON OF 1885, BY C, G. PRINGLE, 
OF CHARLOTTE, VERMONT. 
The numbers are those on Mr. Pringle’s tickets, and include 
some not given on his distribution list. Those ferns left unde- 
termined on his published list will be found here fully named. 
Adiantum Capillus-veneris, L. Rocky hills near Chihuahua. 
456—Adiantum tricholepis, Fée. Santa Eulalia Mt.; April. 
A single station, yielding only a few specimens; none for distri- 
bution, 
Mr. Pringle wrote that he “travelled many miles over the 
steep, rocky hills of Chihuahua, searching their cliffs in vain for 
more. The clump was growing from black mould which had 
accumulated in a fissure of a cliff, about a foot wide, and was 
sheltered from direct access of rain and sunshine by a projection 
of rock near the upper part of the fissure. I never found another 
place just like it, but am confident there is plenty of the fern 
hidden amongst the cliffs which render difficult of access for a score 
of miles the summits of the mountains within view from the city 
of Chihuahua.” 
The fronds on these specimens of Mr. Pringle’s agree per- 
fectly with the excellent figure of this species in Ferns of North 
America, Prof. D. C. Eaton (Plate 59), but the rootstocks render 
some modification of the description necessary, as in these plants 
they are cespitose and not creeping. If this is really Fée’s plant, 
it is difficult to understand how he could have described its root- 
stock as being “rampant’’—creeping—unless we suppose that it 
was inferential from imperfect material in his hands. 
Mr. Baker says that Mr. Pringle’s plant exactly matches the
