2. Conostylis aculeata R. Br. var. bromelioides (Endl.) A. J. Ewart, l. c., 
p. 87. — (C. bromelioides, Endl.) 
Specimens from these localities show all stages of transition between 
C. aculeata and C. bromelioides, some specimens having the inflorescence 
of C. aculeata with the leaf of C. bromelioides, others the leaf margin of 
C. bromelioides, with the number of flower bracts and length of leaf of 
C. aculeata. The distribution seems to preclude the formation of hybrids, 
and hence Bentham's suggestion!) that C. bromelioides might prove to be 
a variety of C. aculeata is confirmed.

8. Conostylis aurea var. longiscapa A. J. Ewart, l. c., p. 37. 
Scapes (14—18 cm) longer than the leaves (10—14 cm). Leaves 
narrow, barely more than 2 mm diam. (instead of halt a cm). In this 
respect the specimens approach var. humilis, F. v. M., but the marginal 
setae are finer and more hair-like. A doubtful specimen from the Mur- 
chison R. has the same characteristics as this variety, but the bracts are 
much longer both on the scape and in the flower head.

4. Crotalaria Mitchelli Benth. var. tomentosa A. J. Ewart, 1. c., p. 37. 
Between Finke River and Charlotte Waters, Kempe. Densely co- 
vered with fine hairs in every part except the corolla and fruit, Smaller 
leaves and fewer flowers than the type species. Axis of inflorescence 3 
to 5 cm long, instead of 10 to 15, leaves rarely more than 2!/, cm long 
by 1!/; broad, instead of 5 to 10 cm long. In other respects the speci- 
mens resemble C. Mitchelli, and differ from C. retusa in the flower, fruit, 
leaves and number of ovules. 
5. Daviesia mesophylla A. J. Ewart, l. c., p. 38. (An nov. spec.?) 
This plant, of which flowering specimens were obtained from W. 
and S. W. Australia, is closely allied to D. microphylla, but differs from 
it in several important respects. It is a small glabrous shrub without 
thorns, the branches striate with raised lines. The leaves are stout and 
rigid, vertical, laterally compressed, with thickened edges, usually convex 
on the lower, and concave on the upper edge, lanceolate or nearly linear, 
but contracting slightly at base, and converging to a sharp poiut at the 
apex, usually 1 em long, but varying from 6 to 12 mm, 1 mm or slightly 
more broad. In transverse section the two marginal veins are larger 
and have more prominent bands of sclerenchyma than the median pair, 
which fuse to one along the basal third of the leaf. The leaf has a 
complete peripheral double layer of assimilating tissue, of which the 
inner layer is darker and tanniferous. In respect to their microscopic 
structure the leaves of D. mesophylla and D. microphylla show a close 
similarity. The flowers are in lateral leafy racemes, either crowded in 
rather slowy clusters of 8 to 12 flowers, on short branches, or sparsely 
scattered on longer, more leafy ones. The flowers are 8 to 10 mm long
