Stachystemon polyandrus is a plant in the Picrodendraceae family, found in the south-west of Western Australia.[1]
It was first described in 1861 by Ferdinand von Mueller as Pseudanthus polyandrus,[2][3] but was transferred to the genus Stachystemon in 1873 by George Bentham.[2][4]
The species epithet, polyandrus, derives from the Greek poly- ("many") and aner - andros ("man"), and thus describes the plant as having many stamens.[5]
Description
Bentham describes the plant:
A glabrous shrub, the stems in all the specimens seen erect, slightly branched, 6 to 8 in. high, arising several together from a woody stock. Leaves very shortly petiolate or almost sessile, oblong or linear, erect or slightly spreading, concave and keeled, rarely above 1\4 in. long and the upper ones shorter. Flowers in terminal clusters, sessile or nearly so, usually 6 to 8 males with 1, 2 or more females. Male perianth "yellow" about 1 line long. Androecium from a little longer than, to twice as long as the perianth, consisting of from 10 to 25 stamens, of which the outer ones have their filaments free almost to the base, the inner ones more or less united in a column, and sometimes 2 or 3 anthers sessile or nearly so at the top of the column. Female perianth about 3/4 line long, the segments broad thin and fringed on the margin. Ovary 2-celled. Capsule not seen.[4]
