Stenanthemum
Stenanthemum is a genus of flowering plants family Rhamnaceae and is endemic to Australia. Plants in the genus Stenanthemum are small shrubs usually lacking spines. The leaves are arranged alternately along the branches, simple, usually folded in half lengthwise on a short petiole. The flowers are arranged in dense heads, usually on the ends of branches with bracts at the base of the flowers, and there are sometimes whitish floral leaves. The flowers are bisexual, more or less sessile and have five sepals, five petals and a tube-shaped hypanthium, the petals hooded over the stamens. The fruit is a schizocarp containing spotted or mottled seeds.[2][3][4]
