Cover Illustration: The vegetative anatomy of root holoparasitic plants is difficult to interpret because of its dramatic morphological reduction. This root holoparasitic plant, Hydnora africana Thunb., parasitizing Euphorbia mauritanica L. (background) in the Richtersveld of South Africa, only emerges from the soil to flower. After the fleshy petals open, the flower emits an odor of rotting meat to attract its pollinators, carrion flies and beetles. In anatomical investigations, the vegetative body of Hydnora triceps Drège & Meyer was revealed to be a rhizome with an unusual modified root-cap-like structure and xylem characteristic of its Piperalean stock. See Tennakoon et al.: Structural attributes of the hypogeous holoparasite Hydnora triceps Drège & Meyer (Hydnoraceae), pp. 1439-1449 in this issue. Photo credit: Jay F. Bolin.
