following characters: ‘‘Vernation fasciculate, erect, acaulose. Fronds 6 
to 8 inches in length, oblong, lanceolate, pinnatifid, densely covered with 
pilose glands, decurrently attenuated to a short stipe. Veins pinnately 
forked. Receptacles punctiform, medial. Sori round. Indusium orbicular, 
occasionally reniform.”8 In habit the plant was said to be “totally at 
variance” with any species of Polystichum, and 
this opinion was formed entirely from her- 
barium specimens. An examination of mate- 
rial in the field indicates even more plainly 
how inappropriate has been the usual sys- 
tematic association of this peculiar plant with 
true members of Polystichum. The fresh 
plants are spongy, very lax, and intensely viscid, 
and except for the peltate indusia have nothing 
1.—Adenoderris to suggest a close relationship with the stiff 
smooth spinulose Polystichums. The venation 
of A. viscidula, which was not indicated by 
Hooker and GrevILLE, is shown in fig. 1, which represents the middle 
portion of a Jamaican specimen (Clute no. 333; U. S. National Herbarium, 
no. 349588). This feature and the position of the sori are discussed under 
the next species. 
A. viscidula is known only from Jamaica and Cuba. JENMAN states 
that in Jamaica it occurs upon ‘“‘rocky banks and skirts of forests 1500~ 
3000 't altitude; plentiful in one place at least between Gordontown and 
Guava Ridge. There is, however, but one sheet in the Jenman Herbarium 
at New York. Other Jamaican specimens are: Clute no. 333; collected 
above Gordontown, March 12, 1900, at an altitude of 4507; Underwood 
no. 2498, collected near the Green River (below Cinchona), April 22, 1903, 
at an altitude of 750™; and specimens collected by D. E. Watt at or ‘cee 
the last locality in May 1903. The Cuban record? is based upon C. Wright 
no. 1052. Specimens of this number in the D. C. Eaton herbarium ‘gabe 
identical with the Jamaican plant; to them is attached Wright’s original 
label stating that they were collected in rocky ravines on mountain sides 
near Josephine, October 25 (1859). 
Adenoderris sp. nov.—A delicate plant of small size, the fronds 
glandular throughout. Rhizome slight, erect, having Jong fibrous rootlets 
rather thickly clothed with delicate bright brown chaff: fronds 8°™ long, 
short-stipitate, spreading, oblong-lanceolate, deeply pinnatifid, with about 
8 Only orbicular indusia have been observed by the writer.
