Description Synaphea tamminensis is a shrub with stems up to long and covered with soft hairs that are hidden by the leaf bases. The leaves are multiplanar, long and wide on a petiole long, the end lobes linear to lance-shaped, long with a fine network of veins. The flowers are yellow, somewhat crowded on a spike long on a openly branched peduncle long. The bracts are long and almost glabrous. The perianth is ascending with a more or less narrow opening and glabrous. The upper tepal is long, about wide, more or less straight and slightly curved downwards, the lower tepal long. The stigma is trapezoid and more or less flat, long and wide and the ovary is covered with silky hairs. Flowering occurs in August and September, and the fruit is barrel-shaped, about long and covered with soft hairs.
