number round the aérophore and at base of the costules and have here fully the 
aspect of scales. These “scales” are, however, not true scales; under the micro- 
scope they are seen to consist of an entangled mass of the long, brown fibrils, 
probably brought together by mites and thus forming Acarodomatia, but not very 
much resembling those common on the leaves of Tilia. — Very remarkable and 
quite unique is the venation. Below the sinus extends to the costa a cartilagineous 
membrane, which in dried specimens often is folded and form a keel quite as in 
the preceding species; the pinnz being incised scarcely to the middle the lower 
4—6 pairs of veins run out to the membrane, and those coming from the same 
side of the costule are united near the edge of the membrane into a common-vein 
running along the membrane to the sinus (see fig. 23). — Other peculiarities of 
the two species are the not deeply cut, stalked pinnz and the subdistinct ter- 
minal pinna.

Type from the West-Indies without exact locality (Herb. Desvaux, Mus. Paris!). 
A most distinct species, very well described by MreTTENIUS and JENMAN (loc. 
cit.) and well figured by FÉre. It can at once be distinguished from D. megalodus, 
with which it often has been confounded, by its coriaceous texture, yellowish or 
greyish underside, its falcate lobed, its simple not stellate hairs of the costze beneath 
and by the presence of aérophores and scale-like fibrils on the coste beneath. 
Further D. megalodus and related species have a terminal pinna like the lateral 
ones, while the terminal pinna of JD. glandulosa is hastate, i. e. below its broad 
base and often confluent with it are to be found a pair of short, lateral pinne; 
the next following pair of pinnzx are much larger. 
Rhizome 2—3 cm thick, ligneous, short-creeping, naked. Stipe often 60—80 
cm long, stramineous, deeply sulcate above, glabrous. Lamina 30—60 long with 
8—10 pairs of very remote (6—8 cm), opposite pinnz, up to 25 cm long by 4 cm 
broad, distinctly stalked with a prominent dark, acute or obtuse aérophore beneath, 
1) D. glandulosa (Bl. O. Ktze. — Aspidium glandulosum Bl. 1828 must subsequently be renamed. 
I propose for it the new name Dryopteris malayensis C. Chr.
