Asplenium longum, v.A.v.R. 



Thamnopteris. — Rhizoma breve, erectum, crassum, demum glabrescens 

 et opaco-asperulum ; squamae lineares, olivaceo-brunneae, nitentes (specie 

 iridescentes), margine in lacinias longitudinales, longe setiformes, subrectas, 

 integerrimas irregulariter dissectae. Stipites approximati, pluriseriati, crassi, 

 + 5 cm. longi, basi decidue squamosi, basibus persistentibus squamarum 

 demum asperuli. Frondes coriaceae, glabrae, lineari-oblanceolatae, 70 — 80 

 cm. longae, in parte superiore 10 — 15 cm. latae, integerrimae, basin decurren- 

 tem versus sensim angustatae, margine paullo incrassatae (subcartilagineae) 

 et auguste recurvatae; costa utrinque leviter prominens; venae ascendentes, 

 leviter prominentes, simplices vel furcatae. Sori in parte superiore latiore 

 frondium, '/a — '/2 partem inferiorem venarum venularumque occupantes, 

 raro venulis sterilibus separati, costam non attingentes; indusium pallidum. 



The fronds examined are not nest-forming; they have the apex somewhat 

 damaged, so that it is impossible to make out positively whether the nor- 

 mally developed fronds are obtuse or acute. — Veins crowded, to + 1 mm. apart.
