30 Rhodora [FEBRUARY 
laer Co., №. Y., 38 (1894). А. ebeneum Ait., var. Hortonae Davenp. 
Кнорока, iii. 1, t. 22 (1901).— On noticing the close correspondence of 
characters given by Dr. E. C. Howe for var. incisum and those of Mr. 
Davenport's var. Hortonae, the writer applied to Prof. Charles H. Peck 
for further information regarding the New York plant. Prof. Peck 
kindly supplied further details as to the type specimen of var. incisum 
and sent a tracing of one of its fronds. From the information thus 
gained it appears certain that the two varieties are identical. ‘The 
older name is of course to be maintained under the altered specific 
name. ‘This attractive plumose variety of A. platyneuron has been 
reported at isolated stations from Vermont to’ Maryland, Missouri, 
and Arkansas. 
ASPIDIUM GOLDIANUM Hook., var. celsum (Palmer), n. comb. 
Dryopteris Goldieana, subsp. celsum Palmer, Proc. Biol. Soc. Wash. 
xiii. 65, t. 1 (1899). The Vienna Rules are unhappily incomplete as 
to the Pteridophytes, ‘This large group of plants, as well as the Bryo- 
phytes and Thallophytes, was not covered by the list of nomina conser- 
vanda. However, a note from Article 9 states explicitly that “lists 
of nomina conservanda for all divisions of plants other than Phanero- 
gams” are subject to consideration at the Congress of 1910. Under 
these circumstances it seems unwise to abandon such well established 
generic names as Aspidium or to take up hurriedly in their place names 
like Dryopteris, which are precisely parallel to many which in the case 
of the flowering plants it has seemed best to discard. 
Woodsia Cathcartiana, n. sp. W. scopulinae affinis et simillima, sed 
minute glanduloso-puberula nec hispidula; frondibus 2-3 dm. altis 
obscure viridibus firmiusculis lanceolatis 25-55 mm. latis bipinnatifi- 
dis; pinnis oblongis, inferioribus distantibus, lobis sinubus modice latis 
separatis oblongis denticulatis; soris submarginalibus; indusio ob- 
scuro eo W. scopulinae simile.— W. scopulina D. C. Eaton apud Gray, 
Man. ed. 6, 691 (1890), non D. С. Eaton, Can. Nat. ii. 90 (1865).— 
Nearly related and very similar to W. scopulina, but minutely glandu- 
lar-puberulent, not hispidulous; fronds 2-3 dm. high, dull green, 
rather firm in texture, lanceolate, 25-55 mm. wide, bipinnatifid; 
pinnae oblong, the lower distant; lobes oblong, denticulate, separated 
by rather wide sinuses; sori submarginal; indusium obscure, similar 
to that of W. scopulina.— 'l'aylor's Falls of the St. Croix River, Min- 
nesota, 1874, Miss Ellen Cathcart (type, in hb. Gray); also on rocks,
