The Steenkop variety is classified as a hybrid, which is denoted by the letter H in official documentation. In a number of sources, the variety also appears under the names Stonehead and Tête de pierre, which are indicated as synonyms or related variants of the same breeding material.
Publications containing lists of vegetable varieties are limited to data on the registration of the hybrid. Detailed morphological characteristics, information on disease resistance, maturity groups, and other qualitative indicators of the produce are absent in open reference books.
