Zusammenfassung

Cordeauxia edulis is a bush well adapted to semi-arid regions. 2n = 24 chromosomes have been counted. The massive and fast growth of its root system contrasts with the slow development of the aerial parts of the seedlings. We suggest a comparison between this slow development and the low content of the seed reserve proteins. Globulins constitute, in fact, only a small part of the whole nitrogen content of the seed compared to alimentary Papilionaceae, e.g.,Lablab purpureus. The distribution of amino-acids, dialysable peptides, salino-soluble proteins and insoluble proteins is analyzed. The amino-acid balance ofCordeauxia seed is compared to those of other food proteins. Compared with other legumes, it is characterized by a methionine deficiency. The absence of phytohemagglutins is a favorable factor in the nutritive value.
