58 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
EXCLUDED SPECIES. 
CrBoTIuM HORRIDUM Liebm. Vid. Selsk. Skr. V. 1: 279. 1849. 
This species is represented in the U. S. National Herbarium by three pinnules and 
part of a secondary rachis of Liebmann’s original material, forwarded from Copen- 
hagen, and said to have been collected by Liebmann in June, 1842, “in sylva montana 
prope Teotalcingo, Chinantla, Dept. Oaxaca, alt. 4-5000’.” The most cursory exami- 
nation of the scales of the rachis shows them to be relatively short, rigid, spinescent- 
ciliate, 5 to 10 cells broad, and thus of a totally different type from those of Cibotium, 
which are capillary, flaccid, and only a single cell broad. Their agreement with 
scales of the secondary rachis of Cyathea princeps (Linden) E. Meyer is so close, and 
the secondary rachis and the pinnules agree so closely in every particular, that Lieb- 
mann’s species must undoubtedly be written as a synonym of Cyathea prince ps 
as recently redescribed by the writer.!| Liebmann’s specimens, according to his 
description and the fragments received, are sterile, as might be expected in young 
plants of a Cyathea attaining the great size of C. princeps and in plants of such small 
size as that attributed by Liebmann to Cibotium horridum. 
TWO NEW SPECIES OF NOTHOLAENA. 
In a recent examination of the Mexican material of Notholaena 
in the U. S. National Herbarium the following two new species were 
detected: 
Notholaena leonina Maxon, sp. nov. 
Fronds 4 to 8 in number, 4 to 11 em. high, fasciculate. Rhizome relatively stout, 
creeping or ascending, 1 to 1.5 cm. long (incomplete), about 4 mm. in diameter, very 
thickly clothed with densely imbricate, lance-acuminate to linear-subulate, dark 
brown scales (2.5 to 3.5 mm. long) with yellowish brown borders, the margins dis- 
tantly and delicately glandular-papillate (especially toward the apex), otherwise 
subentire; stipes 2.5 to 7 cm. long, very slender, blackish, terete, slightly scaly 
toward the base, the scales broader than those of the rhizome, ovate, long-acuminate, 
yellowish brown, concolorous or with darker tips; lamina deltoid to deltoid-oblong, 
acute or slightly produced, 2 to 4.5 cm. long, 1.7 to 3.5 em. broad, bipinnate or rarely 
tripinnatifid in the basal part, simple above, the apex simply pinnatisect, the rachis 
similar to the stipe but lightly sulcate ventrally; major pinne 3 to 5 pairs (those 
above simple, linear-oblong to oblong), subopposite, inserted 7 to 12 mm, apart, 
the basal ones deltoid, with 2 to 4 pairs of spreading pinnules (or segments) below 
the usually trilobate apex, these elongate-oblong, simple and at least partly adnate, 
or the basal ones sessile and with 1 or 2 pairs of minute segments or lobes; pinnules 
or segments in general 1.5 to 2 mm. broad, flat, rigidly herbaceous, grayish green, 
together with the rachises densely ceraceo-papillate throughout; coste of the seg- 
ments wholly concealed above, evident below orly toward the base; margins closely 
revolute about one-third the distance to the costa (or less at maturity), unchanged, 
only partially concealing the dark brown sporangia. 
Type in the U. 8. National Herbarium, no. 834605, collected near Monterey, State 
of Nuevo Leon, Mexico, February 17 to 26, 1880, by Dr. Edward Palmer (no. 1381) 
the specimens received from Capt. John Donnell Smith. 
Known to the writer only from the type number, which apparently was not gen- 
erally distributed to herbaria; at least it is wanting in the National Herbarium set 
received originally, and is not cited by Baker,? who does, however, list numbers 
1382 and 1383 of the same collection as N. pringlei. Eaton® listed no, 1381 as N. 
candida Hook.
