The Red Frangipani ( Plumeria rubra ) is a plant type from the genus Plumeria in the family of Hundsgiftgewächse (Apocynaceae). It is the national flower of Nicaragua and is called Sacuanjoche there.
description
The red frangipani grows as a tree up to 25 m high . The trunk is corky, the leaf scars are clearly protruding. The younger shoots are slightly tomentose. The tightly skinned leaves are elliptical-elongated to elliptical-inverted ovoid. They are up to 40 cm long and 15 cm wide. Towards the front they are pointed or pointed briefly, the base is narrowed. The top is usually hairless, the bottom is more or less hairy to hairless. The secondary veins combine to form a peripheral vein. The leaf stalks are 3 to 6 cm long,
The panicle-shaped inflorescences consist of a few to numerous flowers and are usually terminal. The inflorescence stalks are up to 12 cm long, the flower stalks are between 0.4 and 2 cm long and are hairy. The calyx has a length of about 3 mm and is covered with ovoid-square, spiky and hairy calyx lobes. The crown is salver-shaped, white and purple on the underside, occasionally with a yellow throat. Contrary to the name, the original flower color is not red. In the cultivated forms, the color can vary between red and yellow or even three colors. The corolla tube is 14 to 18 mm long, the corolla lobes are broadly inverted ovate, 30 to 45 mm long and 2 to 3 cm wide.
The paired, horn-like follicles are 15 to 25 cm long and 1.3 to 3 cm thick. They contain 20 to 40 winged seeds. The fruit set is small in relation to the number of flowers.
The number of chromosomes is 2n = 36.
Occurrence
The species is native to southern Mexico and Central America, but is often cultivated as an ornamental plant in tropical and subtropical regions, and occasionally it also grows wild there.
Especially as an ornamental plant, the species in Florida is important for the butterfly species Pseudosphinx tetrio , whose caterpillars it serves as food.
The white-flowered forms of Plumeria rubra are often incorrectly referred to as Plumeria alba ; but this is the valid name of another species.
