Abstract
The new species Hyobanche hanekomii is described and illustrated. It is somewhat intermediate in appearance between H. sanguinea and H. atropurpurea, but can be distinguished from both in several morphological characters that are presented. The new species occurs in the Cape Fold Belt Mountains of the northwest part of the Western Cape.
Key words: Cape Floristic Region, holoparasite, parasitic plant

Hyobanche hanekomii A. Wolfe spec. nov.
.
Corolla deep magenta to magenta-red, inflated above the tube and semi-galeate, and 1.5–2.0 times the length of the calyx.
TYPE:—South Africa. Western Cape: ..., 400 m, 26 September 1997, W.J. Hanekom 2887
(Holotype: NBG 759260!)
Distribution. Rocky soils in Cape Fold Belt Mountains of northwestern region of the Western Cape, from
Citrusdal area to Giftberg (Fig. 2).
Etymology. The specific epithet is in honour of Mr. Willem Johannes Hanekom (b. 1931). Mr. Hanekom is a
keen observer of the flora of the Western Cape, and introduced the author to this new species in 2001. He had made
a collection in 1997 (W. J. Hanekom 2887), which included the following note: “Hyobanche sanguinea L. but with
influence of H. atropurpurea H. Bol.”
