6 Australian Plants. 
have unfolded new disclosures in the affinity or geography of 
the vegetable kingdom, or such as have required an altered 
position in the system of botany, or such again as exhibit me- 
dicinal propertieslike Velleya, Trachycaryon, Beyera, Erioste- 
mon, and other Diosmeze; and not to scatter the connected 
observations I deemed it expedient to annex occasionally, also, 
notes and descriptions of allied species indigenous to other 
parts of Australia. 
RANUNCULACE. 
Myosurus Australis. - 
Scapi filiform or ‘setaceous, upwards but slightly thickened ; 
petals and sepals very small; fruitspike narrowly terete, 
somewhat acute, about an inch long; carpels numerous, 
closely imbricate, rhomboid or almost deltoid, acuminate, at 
the thickened base slightly spreading; styles very short. 
On moist places or in the open plains where rainwater 
lodges for a considerable time, near the Emu Creek, Hop- 
kins’ River, Avoca, Avon, Richardson and Murray, sometimes 
abundant. It is not little surprising that this genus, of which 
hitherto only two species, namely : M. minimus from Europe 
and M. aristatus from the Cordilleras of Chili have been 
noticed, should find its representative alsoin Australia. Our 
species is closely allied to M. minimus; it differs chiefly in 
the loose extracurved basis of the carpels. 
PITTOSPOREZ. 
Marianthus bignoniaceus. 
Innovation silky ; branches climbing, slightly pubescent, at 
length smooth; leaves patent, petiolate, out of an almost 
heart-shaped base ovate, oblong or lanceolate, apiculate, net- 
veined, above puberulous soon smoothening, beneath slightly 
hairy, at the margins undulate revolute, as well as on the nerve 
densely hairy; pedicels axillary single or two, rarely three 
together, at the base bractolate, of equal or twice the length 
of the petiole, as well as the calyx pubescent ; flowers pendu- 
lous; sepals lanceolate, accuminate, four or five times’shorter 
than the cylindrical, somewhat bell-shaped puberulous orange- 
yellow corolla; anthers yellow ; germen villoussilky; capsules 
narrow-elliptical, somewhat compressed, with a longitudinal 
furrow, biloculate, villous, cells many-seeded.
