Description: |
Shrubby perennial herb, usually branching from near the base. Stems woody near the base, densely pubescent. Leaves opposite, linear to linear-lanceolate, 4-12 cm long, leathery, more or less densely pubescent and with soft white hairs on the midrib and margins, pointed and mucronate at the apex; margin often rolled under. Flowers in extra-axillary, 4-12-flowered nodding umbels. Corolla reflexed, white or cream; corona lobes attached c. 1.5mm above the base of the staminal column, cream to green, more or less as tall as the column, laterally compressed. Follicle erect on a twisted pedicel, ovoid, inflated, up to 7 × 2.5 cm, distinctly beaked, more or less densely covered in soft bristles. |
Notes: | It is similar to Gomphocarpus physocarpus but can be distinguished by the fruits, which are more spindle-shaped, ending in a distinct tapering point. When the fruit dries and splits, it releases black seeds, which have long silky hairs attached to enable them to be spread by wind.. Note that the specimen in the photo left is atypical in that it shows the single-stemmed growth form, normally associated with G. physocarpus. |
