acuminate. Petals white, narrowly elliptic, 3-4 mm 
long, obtuse. Stamens 1-seriate, 12-18, anthers all 
fertile. Style persistent, c. 5 mm long. Flowering and 
fruiting: Feb - Sept. Fig. 47 
Common and widespread from north eastern 
Arnhem Land to western Kimberley. Often in small

C. arborescens (F.Muell.) Benth. 
Shrub or tree to 7 m, trunk fluted in tree forms; 
bark grey, rough; usually glabrous. Stipules rusty 
coloured, obscured by the leaves, linear, c. 0.2 mm 
long. Leaves sessile, peltate, imbricate; blades ovate- 
triangular, broadly triangular in cross section, 1-2 mm 
long, 0.75-1 mm wide, the base truncate, margin 
entire, acuminate. Flowers in small terminal clusters. 
Bracteoles connate for 2/3 of their length, abruptly 
constricted into a cylindrical base, 3.5-4.5 mm long, 
the lobes broadly ovate, acuminate. Hypanthium 
narrowly obconic, 10-ribbed, c. 8 mm long. Sepals 
ovate to lanceolate, c. 4 mm long, long acuminate. 
Petals white, narrowly lanceolate, c. 6 mm long, 
acute. Stamens 2-seriate, 45-60. Style c. 5 mm long.

An NT endemic. In the DR known from Melville 
Is. and Litchfield NP area. Common on the western 
margins of the Arnhem Land plateau with scattered 
occurrences elsewhere. On white sand sheets

C. brownii (Schauer) Craven 
C. brachychaeta (F.Muell.) Benth. 
Shrub to 4 m, rarely taller, branchlets often 
pendulous, pubescent or vegetative parts glabrous. 
Stipules c. 0.3 mm long, inconspicuous. Leaves 
imbricate, slightly spreading; petioles closely 
adpressed, c. 0.7 mm long; blades linear, + triangular 
in cross section, 2-11 mm long, 0.3-1 mm wide, acute. 
Flowers in terminal clusters or subterminal due to 
continued growth of the flowering shoot. Bracteoles 
free, obovate with a strong midrib, abruptly narrowed 
to a long acuminate tip. Hypanthium fusiform, faintly 
10-ribbed, c. 4 mm long. Sepals narrowly triangular 
to narrowly lanceolate,.c. 3 mm long, long
