FLORA OF MADAGASCAR. 349 
DANTHONIA LASIANTHA, n. sp. 
D. caulibus elongatis dense cispitosis, foliis subulatis, spiculis villosis tri- 
floris pedicellatis in paniculam laxam dispositis, glumis vacuis brunneis 
membranaceis valde inzqualibus, flore inferiore hermaphrodito gluma 
florifera brunnea oblongo-lanceolata acuminata, flore secundo. imperfecto 
gluma florifera pallida inter dentes apicales aristata, flore tertio minuto. 
Habit of the European Deschampsia flexuosa. Stem very 
slender, terete, about a foot long. Leaves spaced out on the 
stem, with a filiform convolute blade 3-4 in.long. Panicle erect, 
effuse, 3-4 in. long; branchlets very slender. Spikelets brown, 
& in. long, with a small tuft of soft hairs at the base and densely 
hairy inside. Outer sterile glume lanceolate, less than half as 
long as the spikelet ; inner brown, hyaline, } in. long. Lowest 
flower perfect, with a flowering-glume like the inner sterile glume 
in shape, size, and texture. Second flower imperfect, with a 
membranous pale hyaline flowering-glume with a large awn 
between its two long points. Third flower very imperfect.— 
Baron 5234! Near the Cape D. villosa, Nees. Adds this mainly 
Cape genus to the Madagascar flora. 
DIPLACHNE SACCHAROIDES, n. sp. 
D. caulibus elongatis teretibus, foliis pluribus magnis linearibus, spiculis 
4-floris villosis in paniculam amplam dispositis, glumis vacuis parvis mem- 
branaceis ovato-lanceolatis, floribus 3 inferioribus perfectis glumis floriferis 
oblongo-lanceolatis inter dentes apicales longe aristatis, flore supremo re- 
ducto imperfecto. 
Stems erect, above a foot long. Leaves thinly, finely veined, 
4 in. broad, reaching a foot in length. Panicle a foot long, with 
many very compound very slender ascending branches. Spikelets 
narrow, 1 in. long, full of fine soft whitish hairs. Sterile glumes 
oblong-lanceolate, acuminate, brown, membranous, yz in. long. 
Fiowering glume similar in texture, lanceolate, 2 in. long, with 
an awn half its length.— East Androna, Baron 5553! Allied to 
the other Madagascar species, D. aristata, Baker, differing by its 
more ample paniele aud fewer flowers in a spikelet. 
CYATHEA REGULARIS, n. sp. 
C. frondibus amplis firmulis glabris regulariter bipinnatis, pinnis oblongo- 
lanceolatis rachidibus inermibus glabris, pinnulis petiolatis lineari-oblongis 
obscure irregulariter crenulatis, venulis basi szepissime furcatis, soris cos- 
tularibus contiguis biseriatis, indusio magno membranaceo campanulato 
glabro persistente integro vel lobato, receptaculo glabro. l 
Pinnæ 14 ft. long ; rhachis pale brown, without paleæ or spines.
