specimens. It approaches D. asterothrix, from which it differs by its not so densely 
pubescent fronds, glabrous sporangia and proliferous leaves. From JD. asplenioides 
it differs by its obtuse pinne, stellate pubescence of the leaf-lissue, scarcely pro- 
minent veins and nearly sessile pinna; from var. lenera by the distant lower 
pinne and proliferous leaves. 
Most specimens from Cuba, Central America and Florida belong to this variety, 
which represents the most developed state of the species; in the largest form it is 
very different from eureptans, but there are numerous intermediate forms between 
the two varieties.

This seems to me a very distinct species, although some forms of the protean 
D. reptans resembles it very much. The accompanying figure will give an idea of 
its habit. The oblique or short-creeping rhizome, which bears some few stellato- 
pilose scales, bears a small number of leaves, which are of a very thin texture and 
throughout clothed with small stellate hairs. The stipe is slender, stramineous and 
like the rachis densely softhairy by patent, whitish hairs under which numerous 
small stellate hairs are to be found. Lamina 15 cm <= 5—6 cm, bipinnatifid, the 
apex obtuse. Pinnz opposite or subopposite, 6—10 on each side of rachis, the 
lower ones short-stalked, the upper ones sessile, at least confluent, 2'/—3 cm long, 
1—1'/4em broad, obtusely rounded at the apex, slightly broader at the base, the 
lowest pair generally a little shorter and deflexed; and below them a pair of small, 
reduced pinnz are often seen; both surfaces densely and shortly stellato-pilose and 
coste and veins besides with long, soft, patent hairs. Lobes or segments broad, 
obtuse, the middle one soften a little lengthened. Veins rather indistinct, about 4 to 
each side of the midrib of the lobe, the lower pair united. Sori small, exindusiate, 
medial or a little inframedial; receptacle with numerous, long-stalked branched 
hairs; sporangia very loose, at the bearing 2—3 erect 2—3 branched hairs, which 
are very deciduous, and therefore the sporangia may be found to be glabrous.
