Acrodon caespitosus H.E.K.Hartmann
Indigenous Endemic

Morphological description

Plants forming cushion-shaped big and low shrubs, with 60 cm in diameter and a height of 30cm the biggest in the genus. Internodes spongy with a smooth surface, orange and with two lateral folds. Leaves about 50 mm long, 5-9 mm broad and thick, the biggest in the genus, 3-12 keel teeth, only 1-2along margins. Flowers solitary, bracteoles reaching up to the calyx and embracing its base, but starting from near the base of the stalk, the calyx lobes overtopping the petals in the young flower, the flower itself of the short cone type, like those of A. bellidiflorus and A. subulatus, the central cone of about 300 stamens with only few or no filamentous staminodes that are equipped with long basal papillae pointing inwards forming an interwoven layer like a thick ring of felt; the 45-55 petals vittate and with marginal purple margins. Fruits borne on long stalks of about 85 mm above the plant, their stalks bent upwards, the capsule proper the biggest in the genus with diameters and heights of about 12 mm, the top with 5 mm exceeding the sizes of all other species.
