Disa chrysostachya - 1 Disa chrysostachya - 2

DamienGreetings to all our Village plant enthusiasts. Welcome to this weeks’ “Weekly Plant of Interest”. We’ll be looking at a member of the Orchid family recently spotted in relatively low abundance at just 2 localities in the CNR.

Disa chrysostachya (the Torch Orchid in English; and mametsana in Sesotho), is a perennial that rises to between 250 & 650 mm tall. It usually occurs in damp grasslands, marshy areas or below cliff seep lines at altitudes of up to 2400 m A.S.L., and occurs from the Eastern Cape to Limpopo.

 D. chrysostachya has on average 3 – 5 densely overlapped leaves arising from the base of a thick fleshy stem. The inflorescence is tall and cylindrical and slender. The flowers are small, bright orange/yellow with a reddish tinge. A spur is present on each flower and hangs straight down. The flowers are 5 – 11 mm long, flowering from late December to mid Jan. This plant hasn’t been observed growing in great abundance, which would rather obviously make any sightings all the more dear. It’s growth form is also rather unusual and makes for an interesting observation.



The flowers are often pollinated by sunbirds and a multitude of insects and offer a nectar rich meal in return for the pollination service provided by these animals.

Conservation Status

According to SANBI, D.chrysostachya is classified as of Least Concern.
