Brachistus stramonifolium is a plant type from the genus Brachistus in the family of the nightshade family (Solanaceae).
description
Brachistus stramonifolium is a shrub or tree up to 6 m high , the branches of which are covered with short, dense, mostly adjacent, simple or glandular trichomes . The leaves are broadly ovate, often up to 25 cm long and curved with one to four teeth on each side, but occasionally with entire margins. The tip and the lobes are tapered, the base is usually cut off and slightly on one side. The leaf veins and the leaf surfaces are covered with soft downy hairs with upright trichomes. The leaf stalks are about half as long as the leaf blade and also hairy downy. Smaller leaves are rare; they are then less than half the length of the larger leaves.
The flowers stand as clusters of several flowers in the leaf axils, inflorescence stalks are not recognizable, the flower stalks are about 10 mm long, hairy and curved during the flowering phase, later becoming bald and elongating on the fruit. The calyx is shaped like a calyx, as wide as it is long (4 mm) and covered with four pointed, approximately 1 mm long calyx teeth and hairy. The nerve emerges very clearly on drying. The calyx is enlarged on the ripe fruit and partially or completely encloses it. The 7 to 9 mm long, yellow crown is hairy on the outside and the upper area of the inside, cut about 1/3 or more. The resulting corolla lobes are blunted. The stamens are hairy on the (ventral) side pointing to the flower axis, they start approximately in the middle of the corolla tube or a little above it. They are slightly shorter than the elongated anthers , which are usually 2 to 3 mm long and protrude beyond the coronet.
The fruit is a 10 mm large, spherical, indented berry .
Occurrence
The species occurs mainly in Mexico , but there have also been reports of finds from El Salvador , Costa Rica and Panama .
