1. Polypodium (Piiymatodes) quercifolium. L. 
2. Polypodium (Phymatodes) subtriphyllum ; fronde triangulari siibtus puberula 3-5- 
foliolata, foliolis inferioribus petiolalis basi inmqualibus terminalique triangulari-ovatis 
acuminatis pinnatifido-lobatis lobis infimis acuminatis reliquis obtusis, foliolis intermediis 
(si adsint) lanceolatis acuminatis sinuato-pinnatifidis, soris submarginalibus copiosis. 
(Tab. L.) 
Hab. Macao ; Vachell . — This species has the closest resemblance in general structure to the Aspidium 
trifoliatum, S\v. Presl ; but the copious specimens are in all stages destitute of involucre, which, in the 
Aspidium, is large and persistent.

1. Aspidium (Nephrolepis) itserrailwm. Sw — subhirsuium. Asp.hirsutulum. Sw. — 
Schlech. t. 33. 
Hab. Macao, &c. ; Vachell . — Involucre almost entirely orbicular. 
2. Aspidium (Nephrolepis) exaltatum. Sw. 
Hab. Macao ; Vachell . — Involucre lanceolate, opening towards the apex of the pinna. 
3. Aspidium (Nepbrodium) unitum. Br. (vix Sw.) — Aspidium pteroides, Sw. — Of 
this there are two varieties, as we believe them to be; the one larger, with more 
membranaceous fronds ; the other smaller, with subrigid fronds ; and of this latter the 
pinnae vary much in breadth. 
4. Aspidium (Nephrodium) resiniferum. Kaulf. — Hook, et Arn. supra p. 105. — Per- 
haps too nearly allied to A. (Nephrod.) propinquum, Br. Prodr. p. 148. 
5. Aspidium (Nephrodium) molle. Sw. — 13, glabriuscuhm. — 7, paudsorwm; fronde 
latiori soris solumniodo in venulis infimis. — This may prove to be a new species, having 
broader fronds than is usual in A. molle; and in several specimens gathered by Messrs. 
Lay and Collie, as well as in a Chinese specimen in our herbarium from Prof. Lindley, 
the sori are entirely confined to the lowest veinlets, thus forming 2 parallel lines nearly 
the whole length of the pinnae, one on each side the costa.
