DEscRIBED SPECIES OF BoTRYCHIUM 43 
the real facts in the case. We mention this because we have had 
in this country in certain quarters too much of the now obsolete 
notion that ‘‘the Europeans have told us better" concerning the 
status of our own species. Milde recognized only ten species in 
1870. Prantl * enumerated the species known to him in 1884, 
and although he was familiar with the principal German collec- 
tions only, he still recognized fifteen species. Against these 
more rational estimates, the English botanists even in their latest 
pronouncement + can find only six species! The present list 
enumerates thirty-four species whose status is quite definitely 
known, and four others concerning which there are no materials 
for verification that have been accessible up to the present time. 
Besides the above there is material at Kew and Berlin represent- 
ing certainly one and possibly two additional species of the terna- 
tum group from South America, and perhaps a third from Central 
America. This material can best await further study before pub- 
lication. There is also evidence of a species of the simplex 
group in California that awaits further study afield. 
List OF THE KNOWN SPECIES OF BOTRYCHIUM 
Species accepted as valid are in SMALL CAPITALS, except those herein described as 
new, which are in the usual bold-faced type. Species regarded as synonyms of other 
" species are in z¢a/ics with their proper equivalents. Species of uncertain standing owing 
to inaccessibility of types or other causes are also in #fatics, but with no equivalents in- 
dicated. 
Botrychium anthemoides Pres| = ? B. ViRGINIANUM. 
Milde comments on this species in his paper on the Silesian 
ferns and gives a figuré of Presl’s specimen, but unfortunately gives 
two numbers alike on the plate, so as to leave one in doubt con- 
cerning just which is the one intended for Presl’s plant. There 
is, however, little doubt but that the species was based on an 
aborted specimen of the European form of our familiar species.
