Chikanda is a local Zambian foodstuff made from the dried ground tubers of a range of terrestrial orchids in the genera Disa, Habenaria, Satyrium, Brachycorythis and Platycoryne

Cultivated at Dabuyu farms from material collected in Kalongosola village, Katete Distr., Eastern Province

Plants can often be found in areas prone to annual fires

Bulb showing the fibrous neck.

Abnormally tall forms

Mature bulbs displaying long neck

The pure white flowers open about an hour after sunset.

By the first morning, the flowers have developed a slight pink tinge.

The inflorescence sometimes opens in succession leading to a contrast of the new and old flowers.

The infructescence develops quickly after fertilization producing sometimes dozens of seeds.

Seeds are irregular in shape due to their development and can range from pea-sized to over 1cm across.

The inflorescence begins to open in the early evening and the spadix emits a carrion-like odour to attract pollinators

Fully expanded flower shedding pollen the morning after the inflorescence first opened.

Inflorescences can appear from late October through to late December.

Fully expanded leaf with ripening seedhead.

Ripening berries can range in colour from orange to red and are dispersed by birds such as Bulbils.

The berries generally contain 1 to 2 seeds which are recalcitrant and germinate within several weeks from ripening.

The tubers are generally roundish to depressed globose depending on age and produce rhizomatous offsets as a means of vegetative propagation.

Mature bulbs are loose with easily separated scales (which can be used for propagation) though they produce enough seed that it is usually not needed

The inflorescence appears in July to August as the cool dry season transitions into the hot dry season.

The linear leaves appear with the arrival of the rains and are an attractive bluish green colour.

The black papery winged seeds ripen before the rains and are wind distributed.
