C. acutifolius (F Muell. ex Benth.) Maesen 
Rhynchosia acutifolia F.Muell. ex Benth. 
An erect shrub to 1.5 m tall with aromatic grey- 
green foliage. All parts (including pods but excepting 
corolla) are tomentose and usually densely vesicular 
glandular, the upper leaf surface often glabrate to 
glabrous. Stipules persistent, c. 1 mm long. Leafrachis 
to basal leaflets 13-46 mm, 20-64 mm overall; stipels 
obscure; leaflets ovate to lanceolate or elliptic, 
24-65 mm long, 9-25 mm wide, L/W 1.5-4.6, base 
cuneate or rounded, apex acuminate to acute. 
Inflorescences 1-5 per axil, of few to many flowers, 
to 95 mm long; bracts persistent, c. 1 mm long. 
Pedicels 3-6 mm long. Calyx 4-10 mm long; lobes as 
long as tube. Corolla yellow with red or brown stripes; 
standard 10-15 mm long. Style glabrous throughout. 
Pod yellow-brown, 15-21 mm long, 7-9 mm wide. 
Seeds 1-4, oblique in pod, mottled red-brown, 
obovoid, flattened, 4-4.5 mm long, 3-3.5 mm wide; 
caruncle c. 2 mm wide, cleft; funicle c. 1 mm long. 
Flowering: Jan - July; fruiting: Mar - Aug. Fig. 17 
Widespread in tropical Australia; in the DR in 
Litchfield NP and at Mt Bundey, on or near rocky 
outcrops. One population from Mt Bundey has leaflets 
to 65 mm long and 33 mm wide and may be a separate 
species. The leaves are used by Aborigines as a fish 
poison (Russell-Smith, 1985). 
C. marmoratus (R.Br. ex Benth.) FMuell. 
Atylosia marmorata R.Br. ex Benth. 
A slender prostrate vine with annual stems and 
perennial roots. Stems and fruits densely pilose with 
long yellowish hairs mixed with short white hairs; 
golden vesicular glands few, sometimes apparently 
absent. Stipules persistent, cordate, 3-5 mm long, 
c. 3 mm wide. Leaf rachis to basal leaflets 12-105 
mm, 20-130 mm overall; stipels setaceous, to 5 mm 
long; leaflets shortly pilose to glabrate, vesicular 
glands sometimes present on undersurface, base 
C. scarabaeoides 
cuneate or rounded, apex obtuse to truncate; basal 
leaflets obovate, 20-65 mm long, 15-50 mm wide, 
L/W 0.8-1.5; terminal leaflet typically rhomboidal 
to suborbicular, also obdeltoid or broadly elliptic, 
20-105 mm long, 30-85 mm wide, L/W 0.7-1.5. 
Inflorescences 1-3 per axil, of few flowers, to 80 mm 
long or in panicles to 600 mm long; bracts persistent, 
lanceolate to 4 mm long. Pedicels 2-4 mm long. Calyx 
7-11 mm long. Corolla yellow; standard 7-15 mm 
long. Pod mottled red and green, 18-27(39) mm long, 
12-15 mm wide. Seeds (1)2-4(7), transverse in pod, 
mottled red-brown, globular, 4-4.5 mm long, c. 4.5 
mm wide; caruncle 3-3.5 mm wide, u-shaped. 
Flowering: Jan - Sept; fruiting: Mar - Sept. Fig. 17 
Widespread in tropical Australia on sandy or other 
well drained soils. Relatively uncommon in the DR 
where it is known only from southern parts usually 
on soils of granitic origin in open habitats. 
C. reticulatus (Aiton) F.Muell. var. grandifolius 
(F.Muell.) Maesen 
C. grandifolius F.Muell.; Atylosia grandifolia (F.Muell.) Benth.
