Cryptolepis oblongifolia, the red-stemmed milk rope, is a multi-stemmed shrub in the family Apocynaceae. It is native to moist and mesic regions of southern Africa, where it occurs in rocky grassland, grassy woodland or riverine vegetation.[1] It is found from South Africa[2] to Zambia.[1] It grows about 1m tall, and carries widely spaced, opposite leaves on the reddish-brown stems. The yellow to reddish-yellow flowers appear in axillary clusters.
