FLORA NIGRITIANA. 559 
riorem floremque masculum breviter superans, Arista quam 
in U. cimicina multo longior. 
* Tricholzena sphacelata, Benth. ; foliis glabris lanceolato-linea- 
ribus, vaginarum ore geniculisque barbatis, panicula. ramosa 
foribunda, gluma superiore valvulaque floris masculi infe- 
riore hyalino-albidis dorso longe piliferis, acumine fusco 
glabro antice ciliato sub apice longe setifero.—On the Quorra 
at Pandiaki, Ansell. 
Elatior et omnibus partibus major quam T. Teneriffe, cui cæ- 
terum habitu et inflorescentia accedit. Culmi et folia in 
sicco viridia, nec glaucescentia, hee plana, 3-5 poll. longa, 
3-4 lin. lata. Flores iis T. Teneriffe duplo majores. Gluma 
inferior oblonga, pilosa, hyalina, quam spicula duplo tri- 
plove brevior ; superior acumine neglecto linea paullo longior, 
acumen gluma ipsa vix brevius, apice retusum, nervo dorsali 
producto in aristam tenuissimam serrulatam gluma longiorem. 
Floris inferioris neutri et submasculi palea inferior glume 
Superiori simillima ; superior brevior, multo angustior, hya- 
ina, margine ciliata; hermaphroditi gluma superior brevior, 
paleis angustis hyalinis margine ciliatis. 
The Saccharum Teneriffe, Linn.,long since transferred to 
Panicum by Brown, has nevertheless a distinctive character, 
which induced Schrader to establish it as a separate genus 
under the name of Tricholena. Kunth did not adopt it, but 
retained the plant under Panicum. Nees, however, has since 
Te-established the genus on firmer foundations, adding four South 
ican species, which with the present one and the Aira Chi- 
nensis, Retz, (n. 8660 of Wallich’s Catalogue) raise the number 
of known species to seven. I am unable, therefore, to under- 
stand the grounds on which Parlatore, in the first part of the 
Present work (supra, p. 189) restores the original species to 
Saccharum, when it does not at all agree with his own ela- 
borate and accurate character of that genus in his Flora 
Palermitana.
