• Resumen

  • Two new species of Dracaena Vand. ex L. (Asparagaceae, Nolinoideae) from Central Africa are here described and illustrated. Dracaena longipetiolata Mwachala & Eb. Fisch. from Gabon is distinguished from D. phrynioides Hook. by its long petioles and elliptic leaves. Dracaena litoralis Mwachala & Eb. Fisch. is described from Cameroon and also occurs in Equatorial Guinea, Gabon, and Congo-Brazzaville. This new taxon differs from D. braunii Engl. by its smaller flowers whose perianth lobes are shorter than the tube. The identity of D. braunii is discussed and its affinity with D. litoralis analyzed.
