four times as large. M. subfalcaia of Borneo, is about 
the same size as M. dareaecarpa, but has a once divided 
vein. M. paradoxa, widely distributed in Polynesia and 
eastern Asiatic regions, is the largest of the group, 
sometimes as much as six inches long, and has one or 
two divisions of its primary vein. The fifth species, 
M. trichoidea, is, as its name means, actually thread- 
like in structure and size, but longer than M. dareaecarpa, 
and with one to three, fertile portions along its length. 
It is rather common in collections of Philippine ferns. 
The accompanying illustration (Plate 3) shows a 
plant of M. dareaecarpa, life size (fig. 1) an enlarged leaf 
showing the single vein (fig. 2)and a still more enlarged 
section of the leaf showing the groove in which the spor- 
angia are born (fig. 3). These figures are redrawn from 
the Bulletin of the Torrey Botanical Club, Vol. 38, Plate 
3. With them are also illustrated -a leaf of Asplenium 
Trichomanes, life size (fig. 4), and a pinna enlarged to 
show the venation (fig. 5), both drawn from an herbar- 
ium specimen, and a plant, life size (fig. 6 ), and an en- 
larged leaf of Trichomanes Petersii (fig. 7), redrawn from 
Plate 3 in Vol. 7 of the JourNat.

County, 8644; San Augustine, San Augustine County, 
7102 and 12706. 
Found in low, wet woods at Marshall. A form, 
8644a, growing with the other specimens, may be vari- 
etally distinct. A much reduced form, growing on 
rotten logs and hummocks in deep Tupelo and Cypress 
~-swamps at San Augustine, appears to represent a dis- 
taet and perhaps undescribed variety.
