COLLECTION OF CUBAN PTERIDOPHYTA 579 
LomaAriopsis WrIGHTII Mett. 
Of this there are two numbers, both collected near Baracoa — 
a single sheet of no. 150, but no. 220 in some quantity — and 
both are quite sterile. The species was described in Eaton’s 
“Filices Wrightianae et Fendlerianae’’? (Mem. Am. Acad. II. 8: 
195. 1863) and is readily distinguishable by the remarkable 
abruptly caudate apices of the pinnae. 
Polypodium cryptum sp. nov. 
Plant of small stature, 10-17 cm. high. Rootstock creeping, 
I-2 cm. long, about 5 mm. thick ; stipes variable in length, com- 
monly 1.5 to 2 times the length of the lamina, articulated, some- 
what pubescent, and of a dull greenish straw color: laminae lan- 
| ceolate, 4.5—7.5 cm. long, greatest width about 2 cm., simple, 
| pinnately lobed, or for the most part partially pinnate below, the 
lowermost pair of lobes commonly developed into distinct sessile 
or very short-stipitate orbicular or orbicular-cordate pinnae, the 
hext pair rarely approaching this condition, the upper lobes merely 
broad obtuse crenations which decrease gradually toward the 
tapering obtuse apex; venation free, the midvein of each lobe giv- 
ing off on either side about 4 usually simple veinlets which are 
enlarged at their extremities : sori somewhat immersed, broadly 
¢lliptical, borne one to the veinlet almost exactly half way from the 
midve into the extremity. 
The species is based on sheet no. 403232 in the U. S. 
National herbarium, representing specimens collected as no. 231 
by Charles L. Pollard, Dr. Edward Palmer and Wm. Palmer in 
the Vicinity of Baracoa, Santiago province, Cuba, February 1-7, 
T902. The specimens are not in the best condition for study, hav- 
_ Mg somewhat of a weatherbeaten appearance. They are, however, 
uniform in size and general appearance, appear quite mature and 
— ae of such peculiar general morphology that we have thought it 
St to describe them as a new species which we refer with more 
°r less hesitation to the genus Polypodium. The anomalous fea- 
tures are the hidden venation, the unique lobation and the im- 
__ Mersed sori. The venation is indeed very well concealed and can 
_ Scarcely be discerned except by holding the unmounted plant 
| wards strong light. Only the basal veinlets of the lowermost 
_ lobes in the larger fronds fork commonly and these only once or 
_ “ice, most of the veinlets being simple.
