Browallia speciosa
Browallia speciosa is a species of the genus Browallia in the nightshade family (Solanaceae ).
Description
Browallia speciosa is an erect or climbing growing herbaceous plant that reaches the plant height of 70 cm. The stems are hairy with short, simple and most forward -looking trichomes. The leaves are usually up to 6 (rarely up to 9 ) cm long, ovate or elliptical. To the front they are tapered, pointed or blunt at the base shortly. The leaf margins are entire or almost entire, bent on the petiole slightly upwards. The top is sparsely hairy with simple trichomes, the underside is finely hairy along veins. The petioles are as long as the leaf blades in about 1/4.
The flower stems are hairless and only about 7 mm in length, but are extended in the fruit of 3 to 4 cm. The showy flowers have a 5 to 10 cm long calyx. This has a few hairs at the angles. The calyx tube is inflated so that they bubble -like features five clearly distinct angles. About 1 /3 of the length of the calyx make the sepals, which are acuminate - triangular in shape and are bent inward toward the corolla tube. The crown is salverform, blue, mauve or white and often with an irregularly shaped white eye. The corolla tube is 20 to 30 mm long, glabrous on the inside, the outside with fine hairs with short, erect, multicellular and often colored trichomes. The foremost of these trichomes cell is transparent and needle-like.
Most four stamens and a Staminodium are present in a flower, but occasionally five fertile stamens are formed. The stamens of the two upper stamens are green and hairy on top with long, thick, colored and branched trichomes. The lower stamens are shorter and have rotating round stamens. The anthers are yellow to purple. The ovary is glabrous, slightly angled and 3 mm long.
The fruit is a capsule fruit reached a diameter of 2 cm at maturity. It is surrounded by the membranous becoming chalice.
Occurrence
The species is found in South and Central America.
