168 Dr. J. D. Hooxer’s Enumeration of the Plants 
sessiles, 4-5 unc. longe, 1 latze, firmæ sed tenerze, superné glaberrime, medio obscuré 
sulcatee; siccitate pallidé flavo-virides, subtüs paleis elongatis sericeis rufo-fulvis dense 
vestite, apicibus rotundatis, marginibus siccitate subundulatis lente recurvis, venis 
reticulatis obscuris, areolas elongatas efformantibus intra marginem anastomosantes. 
Frondes fertiles 2-3, 3 unc. longz, suberectz, superné in laminam pinnatifidam ex- 
pansz, stipite rachique politis paleis elongatis obsitis. Pinna 5-7, superiores conflu- 
entes, omnes patentes, coriacez, obtuse, $ unc. longe, + late, suprà nude, margine 
angusté revoluto subindusiiformi. Sori luridé rufo-brunnei, paginam inferiorem fron- 
dis omninó tegentes, paleis subsericeis operti. 
The venation of the barren frond is that of a true Pecilopteris, but in the 
(occasional) presence of a free venule it approaches Acrostichum. The fertile 
fronds resemble those of Notochlena, though the sori are decidedly spread 
over the entire under-surface of the frond,

Our specimens agree with the very imperfect description of Sprengel, except 
that the pinnz are nearly opposite. The same plant is also an inhabitant 
of Peru, in the specimens from which country the lower pinna is generally 
forked.
