168 Dr. J. D. Hooker's Enumeration of the Plants 



sessiles, 4-5 unc. longae, 1 latse, firmae sed tenerae, superne glaberrimse, medio obscur^ 

 sulcatae, siccitate pallide flavo-virides, subtus paleis elongatis sericeis rufo-fulvis dense 

 vestitae, apicibus rotundatis, marginibus siccitate subundulatis lente recurvis, venis 

 reticulatis obscuris, areolas elongatas efformantibus intra marginena anastomosantes. 

 Frondes fertiles 2-3, 3 unc. longae, suberectae, superne in laminam pinnatifidam ex- 

 pansae, stipite rachique politis paleis elongatis obsitis. Pinnas 5-7, superiores conflu- 

 entes, omnes patentes, coriaceae, obtusae, | unc. longae, ^ latae, supra nudae, margine 

 anguste revoluto subindusiiformi. Sori luride rufo-brunnei, paginam inferiorem fron- 

 dis omnino tegentes, paleis subsericeis operti. 



The venation of the ban-en frond is that of a true Poecilopteris, but in the 

 (occasional) presence of a free venule it approaches Acrostichum. The fertile 

 fronds resemble those of Notochlcena, though the sori are decidedly spread 

 over the entire under-surface of the frond. 



25. Pteris lutea, Cav., Spr. Sp. PL vol. iv. p. 74. 

 Hab. James Island, Dr. Scouler. Galapagos, Mr. Cuming. 



Our specimens agree with the very imperfect description of Sprengel, except 

 that the pinnae are nearly opposite. The same plant is also an inhabitant 

 of Peru, in the specimens from which country the lower pinna is generally 

 forked. 



26. Gymnogramma ch^rophylla, Desv. 



Hab. Charles Island, Charles Darwin, Esq. Brazil, Paraguay, Jamaica. 



27. LiTOBROCHIA PEDATA, Prcsl (Ptcris, L.). 



Hab. Charles and James Islands, Charles Darwin, Esq., Douglas ^ Cuming. Also found in 

 the West Indies, Brazils, &c, 



28. Adiantum cunbatum, fVilld. 



Hab. James Island, Charles Darwin, Esq., ^ Dr. Scouler. A West Indian plant. 



29. A. PARVULUM, Hook.Jil. ; glaberrimum, fronde tenerrima tripartita, ramis 



pinnatis, pinnis patentibus breviter petiolatis subrhombeo-oblongis apici- 

 bus rotundatis margine inferiore recto superiore denticulato ad soros 

 emarginato basi truncato, stipite glaberrimo, rachi vix pilosa.
