MICROLEPIA BROOKSII sp. nov. 
Pinnis infimis ca. 30 cm longis, 13 cm latis, acuminatis; pin- 
nulis gracili-stipitatis, deltoideo-lanceolatis, argute acuminatis; 
segmentis orbiculari-oblongis, rotundatis, infimo acroscopico 
maximo plus minus inciso excepto proximis et interdum imbri- 
catis, integris, sparsius puberulentibus, aliter ut M. trichosticha 
J. Sm. 
No. 105. 
The peculiar form of the pinnules and segments distinguishes this from 
Microlepia Speluncae as well as from M. trichosticha. The latter has the 
pinnae much longer but hardly wider at the base, the pinnules less dilated 
at the base and relatively broad above and less sharply acuminate, and the 
lobes narrower, farther apart and only the smaller ones near the apex 
entire. The enlarged base of the trichomes is not a very good distinctive 
character. 
HUMATA INTERMEDIA C. Chr. 
No. 89. 
Already published as from Borneo and Perak. The Sumatra plant is 
identical with one determined as this species, from Pahang. 
DAVALLIA SUMATRANA sp. nov. ; 
Rhizomate repente, ca. 7 mm crasso, dense paleaceo; stipite 
50-60 cm alto, castaneo; fronde 80 cm vel ultra alta, 50-60 cm 
lata, vix tripinnata, apice invisa, rhachi per 75 cm non alata; 
pinnis stipitatis, infimis 35 cm longis, 15 cm latis, deltoideo-lan- 
ceolatis, acuminatis, rhachi sursum alata, pinnis sequentibus 
paullo brevioribus; pinnulis stipitatis, infimis 8 cm longis, 3.5 
cm latis, acuminatis, pinnatifidis ; segmentis infimis ala angustis-_ 
sima connexis, pinnatifido-lobatis, lobo infimo acroscopico maxi- 
mo; segmentis sequentibus lineari-oblongis obtusis, serratis vel 
crenatis, coriaceis, glabris, olivaceis; venulis simplicibus, venulis 
spuriis nullis; soris multis, haud marginalibus, immersis; indusio 
plerumque plus quam 1 mm lato et minus quam 1 mm alto, trun- 
cato, laete brunneo cum basi nigra. 
No. 147. “A very large fern.” 
I imagine that this is the “D. decurrens” reported from Sumatra by van 
Alderwerelt, who describes the indusium as “as long as broad.” The real 
Davallia decurrens of Hooker has the indusia distinctly longer than broad, 
and notably small. Of Hooker’s figures, Sp. Fil. 1, Plate XLIV B, 2 is 
correct, but 3, representing a single sorus, is defective, the upper part of 
the indusium being gone. It is possible that D. lobbiana Moore is D. swma- 
trana, but it is described as very much smaller and less cut, but as bearing 
copious sori. 
PTERIS FURCANS Baker. 
No. 20. “Common on newly cut soft rock.” 
Hitherto known only from Borneo. The Sarawak plants are more slender, 
but not otherwise distinguishable.
