      Habitat

      Une des espèces les plus communes de la flore congolaise, en terrain sec ou marécageux, lisière de forêts, forêts sèches, savanes, bords des eaux, champs de lave récents (formes à feuilles très réduites), bords des chemins, cultures, jachères, villages. Elle atteint 2.000 m d'altitude et végète et fleurit toute l'année, même en saison sèche.

        • Uses

          Les feuilles sont employées comme légume ou assaisonnement et la plante serait même parfois cultivée pour cela; elle servirait à teindre en rouge et paraît, d'autre part, une vraie panacée de la médecine indigène: les feuilles ou leur suc, par usage interne ou externe, servent de vermifuge, sont employées contre les maladies de la peau (gale), des yeux, de la poitrine (cataplasme), de l'estomac, du foie, de l'urèthre. Cependant les feuilles, « mangées par erreur », donneraient des vertiges, du délire; elles auraient aussi des emplois en sorcellerie.L'extraordinaire abondance des noms vernaculaires corrobore ces multiples emplois: l'espèce mérite peut-être, à ce point de vue, une étude plus attentive.
