Landolphia kirkii (known as sand apricot-vine, rubber vine or Kirk's landolphia) is a species of liana from the Apocynaceae family that can be found in Democratic Republic of the Congo, Malawi, Mozambique, Tanzania, Zambia, Zimbabwe, and in the KwaZulu-Natal province of South Africa.
The leaves of Landolphia kirkii are oblong and sometimes ovate and can reach up to 9 centimetres (3.5 in) in length. They are glossy green coloured from above, and have a channeled midrib. They have 10-12 pairs of lateral veins, with a net-veining that is slightly raised just above the midrib, that is pubescent underneath. The inflorescence has many flowers, which are white or creamy-yellow coloured and have a diameter of 1 centimetre (0.39 in). The flowers also have a tube that is 3.5–4 millimetres (0.14–0.16 in) long. The green fruits are spherical with a diameter of 15 centimetres (5.9 in), and are edible.
