  • Job Kuijt
Article

Abstract

The first species ofIxocactus Rizzini,I. hutchisonii Kuijt, is described and illustrated. The genus is unique in the family in that it is squamate and lacks inflorescences. Other remarkable features are the dense covering of spines, tetracolpate pollen, the small number of pollen grains per anther, the small size of the flower, and the occurrence of this parasite on stems and roots of other mistletoes.Ixocactus is believed to be related toOryctanthus.
