Casuarina inopkloia, F.v.M. and Bailey. 
The Thready-barked Oak. 
(Natural Order CASUARINACEAE.) 
Botanical description. —Genus, Casuarina, already explained, see p. 74, 
Part XIII. 
Botanical description. —Species, C. inophloia, F.v.M. and Bailey in 
Chemist and Druggist, April, 1882, under the title “ Bemarks on a new Casuarina.” 
Arborescent; aged bark disintegrating into long narrow somewhat fibrous particles. 
Branclilets very thin, slightly streaked, not prominently angular, almost imperceptibly downy. 
Whorls of rudimentary fe«ves.— Bearing 7-9 semi-lanceolar acute teeth. 
Fruit-amenta. —Cylindrical-ovate, or sometimes shortened to an almost globular form, constantly 
depressed at the summit. 
Axis. —Densely beset with straight pale-brown hair. 
Bracts. —Obliterated. 
Bracteolar valves of the fruitlets. —Rather small, semi-ovate, nearly blunt, short-exserted, enlarged 
by a very thick dorsal, rather angular appendage of vertical slight cleavage, and of nearly 
as much protrusion as that of the valves themselves; appendages and valves very slightly 
downy. 
Nutlets. —(When young) pale, the terminating membrane (then) about as long as the nucleus. 
In the southern portions of Queensland, near Roma, F. M. Bailey; near 
Toowoomba, C. Hartmann. 
This species is nearest allied to the common southern C. distyla, especially 
to that variety which, on account of its slender branclilets and small bracteolar 
valves, was formerly distinguished as C. paludosa. Our new species is, however, of 
taller growth, the bark is less solid, the branclilets are neither prominently streaked 
nor conspicuously furrowed, the fruit axis is very hairy, the bract under each fruitlet 
is not distinctly developed, the dorsal protuberance of the bracteolar valve is 
comparatively much thicker, and by partial incision somewhat doubled. Further¬ 
more, the fruitlets below their membraneous appendage are in age probably not 
almost black. The flowers of either sex (not yet seen) may also be different. From 
C. corniculata the species now described is already separated by wanting distinct 
bracts, and by the dorsal appendage of the bracteoles not being long and sharply 
pointed. But there can be no doubt that our new plant is identical with the one
