Honesty. It was formerly called "Pennie Flower, or Money Flower, Silver Plate, Pricksong Wort, and White Satin." ─ Flora Historica, Volume I (1824)

Honesty; Moon-wort; Penny-flower; Money-flower; White Satin-flower; and Silver-plate. The Italian name Lunaria, and the English name Moon-wort, were given to this plant from the form of the seed-vessel, which resembles that of the full moon. Honesty has a reference to the transparency of the partition of the seed-vessel; Silver-bloom, Satin-flower, &c. to its smoothness and glossiness. ─ Flora Domestica, or, The Portable Flower-Garden (1831)

The Satin Bower-Bird is found in the luxuriant and thickly-foliaged brushes stretching along the coast from Port Philip to Moreton Bay ─ The Saturday Magazine, Volume 22 (1843)

SATIN BIRD. This is one of the bower-building birds, constructing a bower or run by means of two short parallel hedges, composed of twigs interlaced together, so artfully arranged that the inner aspect of each artificial hedge is smooth, offering no impediment to the passage of the birds, while the outside is rough with the projecting ends and bifurcations of the twigs. The floor of this run, or short avenue, consists of sticks strewn with shells and bones, and the bower itself is ornamented with the brilliant feathers of various paroquets. ─ Book of Natural History (1852) By By Francis Orpen Morris
