De?*cribed from Yunnan. Mr. Dunn's plunts iv^iw witli tlie publisliotl doberip- 
tiuu, except that the spota on the upper surface- opposite the aori, which give the 
species its name, are not, in these specimens, really conspicuous. 
Polypodium trabeculatum Copel. sp. nov. 
lihizomate repente, 3 mm crasso^ paleis nigris peltatis apiailatis argute 
dentatis 2-3 mm longis dense vestito; stipitibus 1-2.5 cm altis^ validis, 
nigris vel sursum viridescentibus; lamina 12-18 cm alta, sicca vix ultra 
2 cm lata, margine intogro, viva fere duplo latioro, margine crispOj 
utrinque sensim angustata, acuta; paleis nigris mimitis peltatis orbicu- 
laribus vel saepius caudato-ovatis utroque latere satis numerosis; planta 
viva carnoso-coriacoa, vunis principalibus nulliSj vonulis inclusis irregu- 
laribus, sicca lignosa, veuatione omnino occulta; hypodermate hyalino 
nullo, cellulis palisadiformibus trabeculato-incrassatis ; soris in seriem 
unam apud costani iustructis^ glol)osis, 4 mm latis, vix immersis, a paleis 
cinctis, paraphysibus aliter paucis, supra pallido-cinctis. 
Kwangtung Prov., China, ad arbores muscosos. Matthew M. 
A species of the P. lineare group, best marked by the large costal sori and 
very black paleae on all parts of the plant: these are characteristically toothed by 
the black excurrent walls. The numerous thickened lines on the palisade paren- 
chyma walls, running perpendicularly to the surface, prevent any great collapse 
in that direction with loss of water; but the lateral shrinkage is such as I have 
never seen approached by any other fei'n. There is also a shortening of about 
15 per cent. The stoniata are superficial. Dr. Christ, to whom 1 sent a specimen, 
does not regard this as safely separable from P. lineare Thunb., but it seems to 
me sufficiently easily distinguishable by other characters, if the scales on the frond 
be ignored. 
Polypodium hastatum Thunb. 
Dunn 3815. The commonest form, hardly at all hastate; but peculiar in being 
decidedly glaucous. 
Dunn 3808. Hastate-tripartite: peculiar in \U almost nu-nibranaceous lamina. 
Polypodium macrophyllum (Bi.) lleinw.

Dunn SSO'}. The margin crisped, and the largest frond abruptly contracted at 
the base of the lamina proper, approaching the following. 
Polypodium macrophyllum (T>1.) Reiuw. var. fokienense i'opcl. var. nov. 
Foliae lamina propria basi valde liastala, rarius pinnatifida, deinde ad 
stipitcm dceurrcnte. 
Dunn 3757, Fokien. I am not positive that tliis is not Sellujiira cochtrarh 
Christ Ac. Geog. Bot (1007) 142. 
Polypodium Pteropus Bl. 
Kemp f. n. The trilid. dark-green form, with sori all elong-ate along the 
veins, not too certainly identical with the Javan plant. 
Cyclophorus assimilis (Baker) C. Chr. 
Matthew 30. Kwangtung Prov., on limestone. Known oiil^ from China.
