longioribus erecto-patentibus hirsutis vel glabrescentibus tactu valde 
asperis planis vel saepius convolutis instructis, vagina folii culmei su- 
premi paniculae partem inferiorem amplectente vel fulcrante, lamina 
saepe usque 1 dm longa paniculae apicem superante, panicula pallida 
oblongo-cylindrica subdensa c. 7—8 cm longa, spiculis majoribus c. 9— 
9!|; mm longis, glumis subacuminatis glabris vel margine ciliatis ca. 5 
et 7 mm longis, aristis 5 mm longis. 
North Australia: Victoria River, leg. Ferd. von Mueller, 
Dec. 1855. 
A well-marked variety, easily distinguished from the type. It 
approches var. pallidum (= P. pallidum R. Br., Prodr. 185). . 
8. Chloris divaricata R. Br. var. Muelleri Domin, nov. var. 
Elata robustäque, culmis cum paniculis usque plus 6 dm altis, foliis 
vaginis conspicue compressis laminis planis latioribus (latitudinem 25 mm 
attingentibus) instructis, spicis digitatis saepe plus quam 10 ca. 11—13 cm 
longis, spiculis in spicis densiusculis pallidis magnis, glumella ca. 5!/ mm 
longa, lobis glumellae conspicuis aristulato-mucronatis usque ?/,—1 mm 
longis, arista capillari 15 mm et ultra longa, spicula sterili pedicellata, 
glumella sterili profunde (ad !/, usque fere ad 1/3) biloba, arista e sinu 
egredienti plus quam 10 mm longa. 
North Australia: Sturt’s Creek, coll. F. von Mueller, Febr. 1856. 
This may prove to be a distinct species (CH. Muelleri), although the 
dense panicle and the shape of the glumes (but not their size) agree 
with Chl. divaricata. 
9. Sporobolus australasicus Domin, nov. spec. 
Sporobolo coromandeliano valde affinis, sed differt foliis longioribus, 
panicula multo majori et praecipue spiculis longe-pedicellatis et gluma 
prima longiori gluma secunda tantum duplo vel triplo breviori. 
Habitat: N. South Wales, Queensland and North Australia. 
This species is included with Sp. pulchellus R. Br. in Bentham’s 
Fl. Austral. (VII, 623), although the true Sp. pulchellus of Robert Brown 
is a quite distinct and not closely allied species and can be easily 
distinguished by its narrow and soft leaves and the narrow oblong 
panicle besides the characters given in the structure of spikelets. Our 
species seems to come very near to the Hast Indian Sp. coromandelianus, 
which has the same ovate-triangular panicle, but differs in the sessile 
spikelets and the minute first glume. Some specimens from the East 
Indies, already marked by Dr. Stapf as distinct from Sp. coromandelianus 
seem to me to be identical with the Australian Sp. australasicus. 
A good plate (with analysis) of Sp. australasicus is to be found in 
J. H. Maiden’s ,Useful Australian Plants“ no. 99 (Agricult. Gazette of 
N. S, Wales 1908) under the name of Sp. pulchellus R. Br.
