Pachypodium densiflorum var. brevicalyx
Family: Apocynaceae.
Pachypodium densiflorum var. brevicalyx is a local or morphological form of Pachypodium densiflorum distinguished by having the leaf blade tapered below into a short petiole, a shortly pubescent inflorescence, shorter half-size sepals (the green outer whorl of flower parts) only (1-)3(-7) mm long, slightly smaller flowers borne on longer pedicels (7-)15-24(-25) mm long, and hairs inside the somewhat deeper corolla tube.
Sowing instructions: It is easily propagated from ripe seeds, sown in a normal nursery tray, using a well-drained seed-sowing compost and silica sand mixture (silica sand improves drainage) kept moist and at a temperature of approximately 22ºC. The seeds need some degree of humidity for successful germination. One can generally expect seeds to germinate within 3–4 weeks (one month).
