The flowers are borne on flattened, winged, more or less erect cladodes up to {{cvt|8|mm}} wide. The leaves are reduced to reddish-brown scales, {{cvt|1.3–2.0|mm}} long and pressed against the cladode. The flowers are borne singly at nodes on the cladode, each on a pedicel {{cvt|1–2|mm}} long with overlapping, dark brown bracts up to {{cvt|2.5|mm}} long, at the base. The five sepals are {{cvt|5.0–6.5|mm}} long and joined at the base forming a tube with more or less equal lobes {{cvt|1.5–2.5|mm}} long. There are also bracteoles but that fall off before the flower opens. The standard petal is deep yellow with a red base and {{cvt|9.5–11.0|mm}} long, the wings yellow with a red base and about {{cvt|9–10|mm}} long and the keel is dark red and {{cvt|9–10|mm}} long.
