Geographical Distributions

Kalanchoe crena­ta is probably native to tropical and South Africa, naturalised in Brazil, South and South-East Asia. In Java, it is mostly found in the east, on the hot and dry eastern slopes of the moun­tains.

Description

Kalanchoe crena­ta is an erect or ascending shrub that can grow up to 30-200 cm tall. It is usually unbranched, with a strong taproot and with cylindrical or obtusely quadrangular stems.

The leaves are ovate or obovate-oblong to spoon-shaped, measuring 4-30 cm x 2.5-20 cm, with wedge-shaped base, obtuse at apex, thickly coriaceous, with crenate margins, pale green, glaucous or variably tinged with purple and with petiole.

The inflores­cence is up to 30 cm long. The flowers are with sepal lobes, measuring 4-12 mm x 3-4 mm and acute to atten­uate. The petal tube is 8-16 mm long, distinctly widened downwards,  and (orange-)yellow above the greenish base while the petal lobes are oblong-Iance-shaped to elliptical, measuring (4-)8-12 mm x (2-)3-4(-5) mm, patent or subreflexed, erect after anthesis and twisted to­gether and mucronate. The anthers are either all included or slightly exserted for those of the upper series. The smooth carpels are free or sub connate at the base.

Ecology / Cultivation

Kalanchoe crena­ta is a very variable, and widespread species known under a multitude of synonyms. It can be found in a wide range of open, dry, stony habitats up to 2000 m altitude, sometimes abundant in light Casuarina forests.
