1. Antrophyum plantagineum. Kaulf. /3. Lessoni. — A. Lessoni. Bory in Duperrey Voy. 

 .p. 255. t. 28. f. 2. — A. plantagineum. Blume Fl. Jav. t. 30. 



Our plant is exactly the A. plantagineum figured by Blume, and equally the A. Lessoni of Duperrey's 

 Voyage. Nor does the A. Durvillci appear to us to be really distinct from it, according to Bory's description. 



1 . Notochlaena pilosa ; frondibus ovato-lanceolatis bi-tripinnatis, pinnulis oblongis remo- 

 tiusculis subtus margineque recurvo praecipue cum rachibus stipiteque nitidissimo glanduloso- 

 pilosis. 



This is allied to the TV. distans of Mr. Brown, but has a broader frond, more lax pinnules, which are quite 

 destitute of the paleaceous seta? so copious in the former, and sparingly clothed instead with somewhat glan- 

 dular hairs. 



1. Niphobolus macrocarpus ; frondibus lineari-lanceolatis obtusis inferne in stipitem longi- 

 usculum attenuatis subtus incanis, soris serialibus ellipticis magnis prominentibus. (Tab. 

 XVIII.) 



Caudex longus, repens, magnitudine pennse corvinae, adpressim squamosus, hie illic fibrosus; squamis lan- 

 eeolato-subulatis fuscis, margine fimbriatis. Stipites bi-tripollicares, glabri, versus basin articulati, infra arti- 

 culum dense imbricatim squamosi. Frondes pahnares, lineari-lanceolatae, obtusa?, coriacerc, supra areohs (soris 

 oppositis) oblongis depressis, ubique squamulis minutis stellatim pilosis obsitae, demum superne nudae, inferne 

 semper iucana?, margine leviter recurvae. Costa subtus prominens. Sori magni, elliptici, fusci, valde prominentes, 

 in unam seriem intra costam et marginem dispositi, totam dimidiam et superiorem partem frondis occupantes.

1. Diplazium arborescens. Swartz, Syn. Fil. p. 92. Willd. Sp. PI. p. 354. Bory in Du- 

 perrey Voy. v. 1. p. 271. 



We have seen no authentic specimen of D. arboreum: but our plant accords sufficiently with the 

 description. We have received what we consider the same species from St. Vincent in the West Indies, and 

 have doubted if it might not be a more than usually branched state of Asplenium ambiguurn. 



1. Doodia Kunthiana. Gaud, in Freyc. Voy. Bot. p. 401. t. 14. 



Although this entirely agrees with the plant above quoted, we are yet unable to decide if it be really 

 distinct from the Doodia caudata of Mr. Brown. The terminal pinnae can indeed scarcely be said to be
