Notochloe Domin, nov. gen. 
Spiculis magnis multifloris longepedunculatis in paniculam laxissimam 
dispositis, rachide spicularum elongata intra spiculas articulata et rum- 
pente glabra sed sub glumellis breviter callosa et barbata, glumis cari- 
natis elongatis lanceolatis angustis glabris acutis spiculis multo brevioribus, 
inferiori plerumque 3 nervi, superiori subdistanti plerumque 5 nervi, glu- 
mellis angustis glabris glumis longioribus carinatis (dorso haud rotun- 
datis) prominule 7 nerviis rigidiusculis distantibus apice brevissime triden- 
tatis dente medio aristiformi lobos laterales paulo superante, paleis glu- 
mellis paulo brevioribus subrigidiusculis nervis duobus fere marginalibus 
valde remotis percursis, staminibus 3, antheris linearibus 3!/,—4 ynm 
longis, caryopside ignota. 
Species unica mihi nota Awstraliae orientalis subtropicae incola.

New South Wales: Blue Mountains, coll. Chas. Moore (no. 101). 
Planta perennis glabra valde elata foliis valde elongatis angustis, 
ligulis fere in cilias breves dissolutis, culmis mollibus, paniculae ramis 
paucis capillaribus flexuoso-patentibus laevibus alternis paucispiculatis 
(3—1), spiculis longe pedunculatis solitariis permagnis usque 25 mm 
longis 10—14 floris (ex C. Moore, Handb. of the Flora of New South 
Wales, 8—14 floris), glumellis 9—10 mm longis, rachidis internodiis 
11/,—2 mm longis, flosculo supremo minuto ad glumellam sterilem reducto. 
Bentham (l. c.) placed this very remarkable grass under T'riraphis 
but with a query, as the other species of Triraphis have quite a dif- 
ferent structure of spikelets. He also says: ,Munro thinks that this 
grass is incorrectly referred to Triraphis, but I can suggest no nearer 
affinity“. Ferd. von Mueller transfered this species to the genus 
Triodia and although it surely comes nearer the latter than the genus 
Triraphis, I think one is not justified in doing so, as our plant is readily 
distinguished from the known species of Triodia and this not only in 
habit but also in the structure of spikelets. Although Notochloe is rightly 
placed next to Triodia (belonging to the group Pappophoreae), it seems 
to show some slight relation to the genus Danthonia Sect. Micrathera 
belonging to the tribe of Avenaceae. It must be pointed out however 
that Danthonia paradoxa R. Br., the only representative of the most 
curious Section Micrathera, has an isolated position as compared with 
Eudanthonia. 
This curious genus is rendered easily recognisable by the very loose 
panicle, the solitary large spikelets, the distant, long, shortly tridentate
