MANISURIS. 101 
cz, exterior subconcavo-carinata, 3-venia; interior minima. 
Lodicule magne. 
The male spicule is certainly inferior, but it does not be- 
long to the same joint of the rachis with the hermaphrodite, 
as the lowest joint, and general analogy shews. 
The males are biseriate, the females uniseriate. This is 
a remarkable genus. | 
The characters of Kunth’s Manisuris are not іп the least 
applicable to this, which is his second species of the genus ! 
At the base of each hermaph. outer glume is a transverse 
foveola. 
Fl. masculus Ophiuri et Hemarthrie quoad pedicellum. 
 Hermaph. Hemarthriz, palea interior fl. hermaph. minute. 
Manisuris granularis. 
Spica flexuosa. Spicule dissimilis. Spicula inferior ses- 
silis; obovato-rotunda, gluma exterior ossea, scrobicul. obtu- 
sissime concavissima, 
Interior subnavicularis, multo minor, carina apice incrassato 
in cristam. 
Flos minutus ratione glumarum. Fl. exterior neuter, palea 1 
maxime circumvoluta circum florem. : 
Fl. superior hermaphrod. Fl. superioris glumze foliaceo- 
chartacez venosæ, similis, inferior marginibus membran. obli- 
quis altero eroso-fimbriatove, altero integro superior navicularis

Palea externa maga circumvoluta bivenia, 
Interior avenia circumvoluta. 
Manisuris, is allied to Peltophorus, from which however, it 
abundantly differs; if theflowers are bi-paleaceous, it arises 
from the abortion of the inner palea of the hermgphordite 
or female floscule a tendency to which exists in Hemarthria 
and Peltophorus. The difference between the glumes of both 
spicules is remarkable, the male ones look like bractea in- 
terspersed on the spike, the outer glume of the female or 
herm. is remarkable.
