Widespread in northern Australia, on sandy 
soils associated with sandstone outcrops. In the 
DR, known from the Tabletop Range in Litchfield 
NP and Mount Douglas. This species is known 
as T. savannicola Domin in the Flora of the 
Kimberley Region (Wheeler, 1992), but the latter 
has purple flowers and longer leaves with more 
numerous leaflets (Domin, 1926). Some forms from 
Litchfield and Kakadu have shorter, broader leaflets 
and approach T. spechtii.

to cuneate, 24-78(97) mm long, 18-56 mm wide, 
L/W 0.9-1.9(2.7), 2° veins c. 60 degrees to midrib, 
3° veins reticulate, base rounded, apex obtuse, 
emarginate or truncate. Inflorescences terminal and 
axillary, racemose, to 500 mm long, flowers 1-2 per 
node; bracts persistent, narrowly triangular, c. 4 mm 
‘long. Pedicels c. 5 mm long. Calyx 5-6 mm long, 
lobes acuminate. Corolla orange or yellow, rarely 
mauve, gland dotted; standard 9-13 mm long. Pod

suborbicular, flat-sided, 3-3.5 mm diam, ecarunculate. 
Flowering: Nov - Apr; fruiting: Dec - Mar. Fig. 31 
Found in the DR, Kakadu NP and the Kimberley. 
Relatively common in the Hayes Creek - Tabletop 
Range area and known from Melville Is. Associated 
with sandstone substrates in a variety of situations, 
from rocky knolls to creek flats. 
T. ‘Katherine Gorge’ 
An erect perennial shrub to 1.5 m tall. All 
parts with adpressed yellowish brown (rarely white) 
hairs, inflorescence parts sometimes sericeous. 
Stipules caducous, subulate, 2-4 mm long. Leaf
