Most nearly related to E. callifolium (Bl.) Moore, but very much 
smaller and with almost sessile sterile fronds. Elaphaglossum callifolium 
is not known north of Negros.

Very distinct from other species, but closely related to E. decurrens, the 
scales both on the rhizome and scattered over the nether surface of the 
frond being of the same peculiar types. The denser scales along costa 
and margin are larger and less completely dissected. All fronds, even 
the oldest, remain decidedly scaly. The sterile fronds are narrower than 
those of E. decurrens, and not quite so coriaceous. The color is a rather 
light reddish-brown.

As I have previously noted, 5 New Guinea plants believed to represent 
this species are far from uniform. These Philippine specimens are not 
quite identical with any I have from New Guinea, but agree with Christ’s 
brief description rather better than do the latter. 
LOMAGRAMMA BIPINNATA Copel. sp. nov. 
Fronde 40 cm alta, ovata, bipinnata, rhachi castaneo-straminea, 
sparsissime et minute paleata, glabrescente ; pinnis lanceolatis, 
acuminatis; pinnulis valde auriculatis, basiscopice excisis, super 
auriculam lanceolatis, acutiusculis, serratis, herbaceis, glabris, 
venulis liberis simplicibus; pinnulis fertilibus modo contractis, 
sporangiis apices versus more Acrostichi paginam complentibus, 
deorsum saepe in soros venas terminates nudos congregatis.

Aside from the incomplete dimorphism, this is distinguished from L. 
articulata (J. Sm.) Copel. most evidently by the much narrower pinnules. 
In the moderate specialization of the fertile frond this differs decidedly 
from any other Lomagramma, and for this reason it appears to be the 
most primitive species of the genus and the most likely to indicate relation- 
ships and origin. The appearance of the sterile frond is decidedly that of 
Polystichum, but the rhizome is that of typical Lomagramma, which, in- 
cidentally, is not really naked. It bears a fine, sparse pubescence, suggest- 
ing ultimate descent from Dennstaedtia rather than from Dryopteris.
