Only the shape of the calyx distinguishes this singular and beautiful plant generically from 
Burgesia, unless distinctive notes should be derived from the fruit. The habit, the racemose 
inflorescence, the large corolla and the elongated style are deemed sufficient for its sectional 
separation from the other Leptosemata. 
I have chosen this, the most remarkable and the most ornamental of the new plants 
gathered by the intrepid and skilful John Macd. Stuart during his journey across central 
Australia, to express, by a tribute of science, my regards for the gentleman by whose munifi- 
cence the brilliant exploit was solely initiated and supported. 
CAJANUS GRANDIFOLIUS. 
(Sect. Atylosia.) 
Erect, stout, not climbing ; branches streaked, as well as the petioles silky-tomentose 
with fulvous hair ; leafstalks about as long as the leaves or shorter; stipules ovate-lanceolate, 
long-pointed, caducous; lateral petiolules remote from the terminal one; stipels subulate , 
deciduous ; leaflets large, the lateral ones oblique broad-ovate, the terminal one ovate-rhomboid, 
all velvet-silky on both sides, paler and prominently net- veined beneath, rather acute on both 
ends ; peduncles about as long as the petioles or considerably longer ; pedicels corymbose or 
subumbel late, as well as the calyx silky-tomentose ; lobes of the calyx almost linear-subulate ; 
the upper and lower one nearly as long as the somewhat persistent corolla , considerably longer 
than the lateral lobes and the tube ; vexillum faintly callous above the base ; the margin of its 
basal lobes introflexed ; pods nearly oblong, densely silky-tomentose. 
Signal Hill, Upstart Bay. Found during Mr. Aug. Gregory’s expedition on the Burnett 
Ranges and on the Victoria River. 
A shrub, several feet high. Leafstalks lengthened to the distance of | inch beyond 
the lateral leaflets. I he latter l|-3 inches long, provided with stout petiolules, which are 2-3 
lines long. Peduncles bearing at the summit occasionally a diminutive trifoliate leaf. Brac- 
teoles cordate-ovate, acuminate, 2-3 lines long. Pedicels twin, somewhat shorter than the 
calyx. Lobes of the latter indexed at the margin, the upper one acutely bidentate. Petals 
smooth. Vexillum orbicular, pure yellow, or but slightly streaked with dark veins, hardly 
■3 i nc h long, with very short basal lobes and with an unguis, which is 1 line long and indexed 
at the margin. Wings a little shorter than the carina, yellow towards the apex, pale towards 
the base, semilunar-oblong, with semihastate base and with a narrow flat short claw. Petals 
of the carina coherent from above the middle to below the apex along their lower margin, 
almost semicircular, with truncate base and with a narrow unguis of about 1 h line length. Stamens 
diadelphous, glabrous. Anthers dorsifixed, yellow, subcordate-oval, ^ line long. Style, with 
exception of the base, glabrous. Stigma minute, truncate. Pods about 1 inch long, compressed, 
short-beaked, with several seeds. The latter not seen in a matured state. 
According to Wight and Arnott’s definition (Prodr. Flor. Penins. Ind. Or. i. 257) Atylosia 
inajoi approaches to this plant closely in its affinity. The remoteness of the lower special leaf- 
stalks from the upper one, and perhaps also the presence of stipellce, seem to separate it however 
as well from that species as from the less similar A. Candollei, A. rugosa and A. lineata, and 
fui ther the form of the calyx and the disposition of the flowers offer evident distinctions from 
A. Lawii, whilst the not climbing habit distinguishes it at once from A. scarabasoides, A. albi- 
cans and A. elongata. 
CAJANUS CONFERTIFLORUS. 
(Sect. Atylosia.) 
Grey velvet-tomentose ; leafstalks as long as or shorter than the leaves ; stipules lan- 
ceolate-subulate ; petiolules arising from one point ; leaflets nearly ovate, blunt, netted by 
beneath strongly prominent veins ; peduncles as long as the leaves or longer ; flowers corymbose; 
lobes of the calyx lanceolate-subulate, all shorter than the corolla, longer than the tube ; vexillum 
faintly callous at the base, the margin of its basal lobes introflexed. 
Magnetical Island. I he same species occurs at Rockhampton, according to a specimen 
transmitted by Mr. A. Thozet. 1 
Ibis plant is smaller in all parts than the preceding one. The fruit is as yet unknown. 
It seems principally to differ from Atylosia rugosa in its inflorescence. A similar plant 
found on the Victoria River and distributed under the name A. cinerea, appears to differ onlv 
in a thin velvet-indument and in remote petiolules, the position of the latter being evidently 
subject to some variation. Another plant of this genus from the same locality and from the 
Gulf of Carpentaria, may, as a variety or as a species, be named A. acutifolia ; it has its leaf- 
stalks considerably extended beyond the lower leaflets, its leaves distinctly acute and its slender 
peduncles often much elongated, whilst the pods are generally 2-3-seeded, ovate, the indument 
variable to a great extent, and the corymb sometimes elongated to a raceme. 
The stronger development of the strophiole, observed amongst Australian species in A 
acutifolia, offers the only and not a manifest differential character by which Atylosia can be 
separated from Cajanus, inasmuch as the corolla of Atylosia is not always persistent, and as the 
insertion of the special leafstalks is equally uncertain as the presence of stipellse whilst the 
presence or absence of callosities of the vexillum are in other genera, for instance Swainsona. 
only regarded as notes available for specific discrimination. Under these considerations I would 
suggest that Atylosia may be subordinated as a subgenus to Cajanus. In Atylosia albicans the 
stipellae are distinctly developed. The actual limits of the variation, to which these plants are 
subject, is neither in the Indian nor in the Australian species ascertained, but apparently very
