2—3. Probably such leaves develop only in old plants. In quite young plants 
the pinnz are sometimes quite entire, ovate or nearly circular, the veins free: such 
forms have been referred to JD. cordata. Some forms are nearly destitute of 
stellate hairs. 
The following specimens are typical, if such a term may be used here.

Santiago, El Yunque, PoLLARD and Parwrm nr. 122 (W) — Prov. Habana, San Antonio de los 
Banos, AngaRcA nr. 4531 (W), Baker nr. 2755 (W) — Prov. Pinar del Rio, near El Guama,

Bahamas: New Providence, Rawson W) Rawson (B). 
Venezuela: Caripe, Morirz nr. 213 (B). 
3. var. angusta n. var. 
Fronds rather uniform, often radicant, very short-stalked, linear, often con- 
siderably narrowed downwards. Pinnz distant, small, rarely more than 1!/2 em 
long, often only !/sem, scarcely '/2 em broad, obtusely rounded at the apex, the 
margins entire or slightly crenated, rounded or auricled at base; secondary véins 
once or twice forked, free or united near the edges. 
Very characteristic by the long, very narrow, flaccid leaves, which are often 
rooting as in eureptans. It approaches D. cordata, from which it differs by its di- 
stant pinnz, thinner texture, long proliferous apex and pubescence.

Porto Rico: Utuado, SivTENIS nr. 6380 (C), 6588 (CC; pinnz nearly circular).

4. var. conformis n. var. 
Differs from var. eureptans by its mostly uniform leaves, which have the ge- 
neral habit of the short-stalked mostly sterile leaves of eureptans, but the stipites 
are rather long and the lamina often much larger. Long-stalked, differently shaped 
leaves are not to be found, but often the radicant leaves are somewhat narrower 
than the non-radicant ones. — All leaves long-stalked, stipe often as long as the 
lamina or even longer. Lamina mostly lanceolate in outline, often 20cm or more 
long but as a rule shorter, 5—8 cm broad, shortly narrowed downwards. Pinne 
very short-stalked the lower ones mostly rather shorlened, distant, the largest up 
to 5 cm long, often cut !/s or more to the costa and cordate at base. — It is less 
proliferous than eureptans, still one or two radicant leaves are to be found in most
