Budryopteris rhizomate (?). Stipitibus rigidis, stramineis, basi 

 squamis brunneis deciduis sparse instructis, vix 10 cm. longis. 

 Lamina ovato-lanceolata, ad G-y dm. longa, medio ad 2.5 dm. lata, 

 versus basin sensim attenuata, ad apicem serratum breviter acumi- 

 nata, gramineo-viridi, firmo herbacea, rachi straminea glaberrima, 

 bipinnatifida. Pinnis numerosis, valde approximatis, i cm. remotis, 

 inferioribus 3-4 jugis sensim abbreviatis, imis auriculiformibus, 

 lobatis, ca. i cm. longis, medialibus maximis, linearibus, 10-13 cm.

 neas sparse setosis, utrinque inter venas sparse et minute puberulis 

 denique glabris, ad alam vix i mm. latam pinnatifidis. Laciniis 

 numerosis, valde approximatis, sinubus angustissimis acutis sepa- 

 ratis, parum obliquis, integris, acutis, marginibus planis, basalibus 

 aequalibus. Yenis lo-ii jugis, indivisis. Soris parvis, luteis, sub-

This new species can only be compared to D. panarneiisis and D. 

 Sprengelii, from both of which it differs in its remarkably closely- 

 placed overlapping pinnze and segments, the leaf resembling the 

 sterile frond of Matteuccia struthiopferis — hence the specific name. 

 It resembles large forms of D. panamcnsis in general habit, especially 

 in the base of the lamina, but it is considerably different in its almost 

 glabrious and eglandulose lamina, in its not very oblique segments,.
