Dennstaedtia Merrilli Copel. n. sp. 
Rhizomate repente, ca. 1.5 cm. crasso; stipite erecto, valido, deorsum 
1 cm. crasso, 60 cm. alto, rhachique badiis, sub lente puberulis, oculo nudo 
glabrescentibus ; fronde 100-120 cm. alta, ca. 50 cm. lata, quadripinna- 
tifida, pinnis inferioribus diminutis, maximis 30 cm. longis, 11 cm. 
latis, acuminatis, rhachibus infra puberulis ; pinnulis deltoideo-lanceolatis, 
valde acuminatis; pinnulis” deltoideo-lanceolatis, obtusis decurrentibus, 
substipitatis, infima acroscopica maxima usque 2 cm. longa, 1 cm. lata 
in segmenta subremota, utroque latere ca. 4, oblonga, obtusa vel truncata 
integra vel obscure serrata ad costam alatam, pinnatifida, glabris, herba- 
ceis, infra pallidis; soris in sinubus marginalibus, immaturis interdum 
submarginalibus, fere 1 mm. latis, margine frondis saepe inflexa, cum 
indusio vero calicem imperfectam efficiente ; receptaculo valido; annulo 
interrupto. 
In silvas, 1,800 m. s. m. (No. 5949). 
This plant might, with equal reason, be assigned to Microlepia, or Denn- 
staedtia; I should have preferred to have called it Microlepia, since that genus 
is at best undefinable, but its generic separation from Dennstaedtia flaccida would 
not be justifiable on any ground. Its probable relatives are Dennstaedtias of the 
D. flaccida group, Microlepia liirta and the so-called M. dennstaedtioides Copel. 3 
with regard to which I am now prepared to accept Christ’s judgment and call it 
Dennstaedtia, D. dennstaedtioides. 
I have come to the conclusion that Microlepia will have to be abandoned, as 
a genus, and regarded in the future as the primitive section of Dennstaedtia.
