description
Appearance and leaf
Synaphea brachyceras is a relatively small, round-growing, prostrate, evergreen shrub that reaches heights of 0.3 meters and a diameter of 0.4 meters. The bark of young twigs is hairy.
The alternately arranged, 11 to 23.5 centimeters long leaves are divided into petioles and leaf blades. The petiole is hairy. The entire, flat leaf blades are simple, divided into two or three parts and little lobed or incised up to the midrib, the hairs lying close. The distance from the base of the blades to the lowest, 6 to 6.5 centimeters long leaf lobes is 6 to 23 centimeters, the end lobe is 6 to 15 millimeters long and 2 to 6 millimeters wide. The leaf blade is hairy when pressed.
Inflorescence and flower
The flowering period in Australia extends from August to September or October. The inflorescence stem is 17 to 32 inches long. The bracts are 1.5 to 2 millimeters long.
The seated, hermaphrodite flowers are four-fold. The yellow, hairy bloom is 5 to 6 millimeters long. The bracts are fused tubular to at least half their length. The adaxial tepals (Tepalen) are 5 to 6 millimeters, the abaxial 4 to 4.5 millimeters long. There are four stamens , only three of which are fertile. Each flower contains only one upper, hairy carpel . The bald stylus with the scar disk is 3.8 to 4 millimeters long, the scar itself is about 1.5 millimeters long and about 0.8 millimeters wide.
The follicles are 4 to 5 millimeters long.
Occurrence
Synaphea brachyceras is endemic to the Australian state of Western Australia . The distribution area includes the Southwestern Botanical Subregions Avon Wheatbelt (AW) and Jarrah Forest (JF).
Synaphea brachyceras thrives on a flat and gentle slope in a small area of the Wheatbelt between Wagin and Williams . There it grows over laterite on sandy-gravelly subsoil .
