PROTEACEAE 119 
BANKSIA Lf. 
A predominantly Australian genus of c. 72 species with 1 species extending to New Guinea and eastern 
Indonesia. One species in the NT. [Taylor & Hopper, 1988; George, undated] 
B. dentata Lf. 
Shrub or small tree to 6 m. Branchlets densely 
pubescent with closely tangled crisped hairs, 
interspersed with longer patent hairs. Petiole 10-12 
mm long. Leaf blades strongly discolorous, oblan- 
ceolate to spathulate, 140-270 mm long, 47-70 mm 
wide, L/W 3.3-5.7, glabrous above, densely white 
arachnoid below, lateral veins + at right angles, deeply 
dentate with lobes spinose. /nflorescence terminal, 
spike-like, densely flowered, rachis thick and woody, 
to 170 mm long and 100 mm wide. Flowers 
zygomorphic. Perianth free, grey silky pubescent. 
Hypogynous glands present. Style yellow, glabrous, 
pollen presenter not differentiated, erect, linear. 
Infructescence fusiform, woody, with many 
transversely orientated follicles, golden pubescent, 
80-110 mm long, c. 40 mm wide; follicles c. 15 mm 
wide, opening by 2 hard woody valves. Seeds 2, 
with a thickened separator between them, wedge- 
shaped, black, c. 11 mm long, wing on one end, c. 9 
mm long. Flowering: Mar - Aug; fruiting: June - Aug. 
Fig. 34, 35 
Occurs from eastern Indonesia, New Guinea to 
northern Australia; common in the DR on sandy, 
seasonally wet areas. The rachis of the infructescence 
is used for carrying fire (Wightman & Brown, 1994). 
GREVILLEA R.Br. 
Shrubs or trees. Flowers zygomorphic; receptacle (torus) concave, transverse to oblique on the pedicel. 
Hypogynous glands free or variously fused or lobed. Ovary stipitate or sessile; ovules 2; pollen presenter 
discoid to + conical, oblique to erect or lateral on the style. Fruit a follicle; seeds (1)2, with a membranous 
wing or with a terminal elaiosome. 
A genus of c. 260 species, mainly Australian but a few species extend to New Guinea, Indonesia and New 
Caledonia. Thirty four species recorded for the NT with 15 in the DR [McGillivray, 1993]. A number of 
species are used for a variety of purposes by Aboriginal people. The seeds of G. decurrens and G. heliosperma 
are eaten raw. Nectar from many species is eaten. Some species such as G. dryandri have medicinal uses.. 
Species with caustic fruits such as G. dimidiata are used to produce tribal skin markings (Levitt, 1981; Wightman 
et al., 1992a,b)
