Among the grasses growing among the reeds, we perceived the ANDROPOGON SERICEUS and an ERIANTHUS, which appeared to differ from E. FULVUS in having no hair upon the knees. The smooth variety of the European LYTHRUM SALICARIA, raised its crimson spikes of flowers among the reeds of the Macquarie, as it does in England on the banks of the Thames. We saw also MORGANIA FLORIBUNDA, SENECIO BRACHYLOENUS (D. C.), a variety with toothed leaves, also a BRACHYCOME resembling B. HETERODONTA, only the leaves were entire. A new species of LOTUS appeared among the reeds, very near the narrow-leaved form of L. AUSTRALIS on the one hand, and the South European narrow-leaved form of L. CORNICULATUS on the other; the flowers were pink, and smaller than in L. AUSTRALIS.[*] Also an ETHULIA [**], which may, on further examination, constitute a new genus; it was found by Allan Cunningham on the Lachlan.
