& rea t. It is indeed possible, that we possess but one Australian species, for which the name C. 
confertiflorus might be retained. 
It would also be of interest to ascertain whether the Australian congeners could be made 
available for food in the manner as Cajanus Indicus, serving as a substitute for peas in tropical 
countries. 
In the collection occurs also a fruit specimen of a Cyanospermum, which may receive the 
name C. Australe. Being destitute of flowers and leaves, the specimens are insufficient for 
establishing a proper diagnosis. The calyx is much smaller and thus very considerably shorter 
than the pod, and the seeds are dark blue, characters which mark this a most singular species. 
LOTUS AUSTRALIS.

Cumberland Islands. Extends sparingly north-westward to the Gulf of Carpentaria. 
Cattle are extremely fond of this herb, which therefore might be cultivated in sandy 
tracts, not readily available for other culture plants. It grows luxuriantly in some of our low 
sandy coast tracts.

INDIGOFERA PRATENSIS. 
Suffruticose, diffuse, almost silky ; leaves short-stalked, pinnate, with usually 5-9 pairs 
of leaflets ; stipules linear-setaceous ; leaflets oblong-oval , rarely ovate, blunt, mucronulate, 
finely penninerved; stipelke minute, setaceous; racemes axillary , many flowered^ conspicuously 
stalked; pedicels short ; bracteoles caducous, linear-subulate ; teeth of the calyx deltoid ; the 
lower ones pointed ; corolla purple, rather large ; standard subovate, one-fourth longer than 
the glabrous wings, outside silky, about as long as the keel ; petals of the latter towards the 
apex silky ; pods cylindrical, soon deflexed ; seeds cubical. 
Port Denison. Noticed by the author of this treatise on the Rivers Burdekin, Dawson, 
and Burnett, as well as in the neighborhood of Moreton Bay. 
A pretty plant, never more than a few feet high. Stems and branches nearly cylindrical. 
Leaves seldom reduced to two or three pair of leaflets. Stipules often from 2-4 lines long, for 
a while persistent. Racliis of the leaflets narrow, channelled, 1|— 4 inches long. Leaflets ^-1 
inch long, flat, provided with a petiolule of about 1 line length, opaque, paler beneath. Rachis 
of the raceme angular. Pedicels solitary, about 1 line long. Bracteole of about the same 
length. Upper teeth of the short calyx somewhat remote; the lowest the longest, yet not 
much elongated. Vexillum 4-5 lines long, almost flat and sessile, but slightly acute, as long as 
the keel, not callous. Wings oblong-cuneate, ciliolate, sessile ; the margin next the base 
indexed. Keel slightly fringed, somewhat acute ; its petals dissolved in their lower part, near 
the middle short and blunt-calcarate. Stamens diadelphous. Nine of the filaments highly 
connate. Anthers ovate, short-mucronulate, affixed above the base. Style ascendent, glabrous. 
Stigma finely bearded. Pods 1-1 \ inch long, about 1J line thick. Seeds hardly 1 line long, 
slightly shining, squalid yellowish-brown. 
A very similar plant, with fewer almost orbicular leaflets, less conspicuous stipels and 
smaller flowers, was found on Sea Range (Arnhem’s Land), and has been designated in the North 
Australian Herbarium I. saxicola. 
Our plant touches in its affinity on several Asiatic species, compared on this occasion. 
1. bracteata is to be distinguished by the form and greater size of the bracteoles, which, more- 
over, are less caducous. I. heterantha, which I find amongst Fortune’s Chinese plants, differs 
in less evidently penninerved and usually smaller leaflets with less conspicuous stipellce. in 
smaller flowers, and more particularly in subulate teeth of the calyx. I. hebepetala, which, 
according to a somewhat imperfect specimen received from Ch. Moore, Esq., of Sydney, occurs 
on the Richmond River of East Australia, has fewer and broader leaflets and nearly glabrous 
petals. I. decora, which has become naturalized at Moreton Bay, shows more acute leaflets and 
a densely fringed carina. I. pulchella produces larger bracteoles, smaller stipelke and almost 
glabrous petals. Some of these plants may be expected to occur in N.E. Australia. Dr. Hooker, 
in his valuable list of plants diffused as well over Australia as over India (Conf. Introduct. 
Flor. Tasm. p. 43), enumerates the following species: — I. linifolia, I. cordifolia, I. enneaphylla, 
I. trifoliolata, I. viscosa and I. hirsuta. To these are to be added I. hebepetala and I. trita, the 
latter being by no means rare, occurring from Arnhem’s Land to Moreton Bay. Some of the 
other species have an equally wide range. I. Australis is scattered in manifold forms over the 
greatest part of extratropical Australia. Two other known tropical Australian species have as 
yet not been identified with Indian congeners, and are probably endemic.
