Asplenium (Thamnopteris) Simonsianum, Hook. 
Ca 0 spitosum glaberrimum subcoriaceo-membranaceum, frond- 
ibus (sesquipedalibus) elongato-lanceolatis abrupte anguste 
acuminatis, basi in stipitem perbrevem longe attenuatis 
angusto-marginatis, venis crebris ante marginem apicibus 
coalitis in lineam continuam marginalem, soris copiosissimis 
erecto-patentibus totam paginam fere occupantibus.

This is a true Neottopteris of J. Smith, (Thamnopteris, 
Presl ), as far as the union of the apices of the veins into a 
continued intramarginal line is concerned ; but such a genus 
is most unnaturally separated from several simple-fronded 
Asplenia . As a species its affinity is with Neottopteris Phyl - 
litidisy J. Sm. (Asplenium, Don\ and no less with N stipitata , 
J. Sm. (which I cannot distinguish from the preceding), but 
the fronds are here much narrower, more suddenly and narrowly 
acuminated, and at the base very much more attenuated. My 
only specimens are from Mr. Simons.
