River Rose

Bauera rubioides

"Bauera rubioides" is a shrubby, flowering plant found in the eastern states of Australia. It has also been referred to as madder-leaved bauera, a comparison to another genus which is commonly named madder.

Appearance

Rambling shrub to 2 metres. Branches; opposite, rigid and many. The leaflets on the species are acute to broadly so, having 4 - 10 teeth on a serrated margin, 5 – 15 mm long and 2 –3 mm wide.
Flowers on pedicels, erect, but drooping to the ends. Sepals are 6 - 8, around 4 mm, and also toothed.
For the flower's most notable aspect, Sims gave in 1804;

... "Corolla", rose-coloured,
eight petaled, but one is deficient; "Petals" lanceolate,
concave, patent, quite entire. "Filaments" many, shorter than
petals, attached to the inside of the calyx, not to the receptacle,
...
"Anthers" yellow, roundish. "Germen" roundish, somewhat flat-
tened, emarginate. "Styles" two, filiform, divergent. "Stigmas"
acute.

He also notes the lack of scent. The petals may be white, the numerous stamens are creamy white. The name, "rubioides", was given for a resemblance to "Rubia"; Sims notes...

The trivial name is derived from the resemblance which it bears, especially in its young state, to a "Rubia", not a "Rubus", as Mr. Andrews, with his usual accuracy, would have it. Flowers through the greatest part of the Summer.

Curtis's Botanical Magazine Vol 19. p715

Flowering is, at least lightly, throughout the year, most heavily in spring and summer.
