Dipcadi marlothii has small yellow flowers with some green on the outside of the corolla. The outer three tepals are spreading, the inner three form a tube. the tepals are long and narrowly oblong with rounded tips. Flower colours of flowers of this species include lime green and some brown with cream on the inside. The green pedicels, spaced sparsely along the raceme, allow the flowers some nodding. Withered flowers lower down turn upwards as the ovaries mature into fruits, as can be seen here.
The plant is a perennial geophyte or bulbous perennial. It occurs in both South Africa and Zimbabwe, first found growing on rocks in Mpumalanga (www.rareplants.co.uk).
