The trumpet wines ( Podranea ) are a genus of plants in the trumpet tree family (Bignoniaceae).
description
Vegetative characteristics
The trumpet wine species grow as evergreen , climbing shrubs and reach heights of up to about 5 meters.
The opposite arranged leaves are divided into a petiole and a leaf blade. The imparipinnate leaf blade is composed of 5 to 13 egg-shaped, pointed pinnate leaves .
Generative characteristics
The flowers stand together in terminal, panicle inflorescences . The hermaphrodite flowers are zygomorphic and five-fold with a double flower envelope . The five petals are fused bell-shaped. The corolla is pink and veined darker in the throat. The corolla, which is up to 7.5 × 7.5 centimeters in size, is weakly two-lipped and ends with five lobes. They have two long and two short stamens .
The up to 40 centimeters long, cylindrical capsule fruits open with two lobes when ripe and release their numerous winged seeds .
Systematics and distribution
The genus Podranea was established in 1904 by Thomas Archibald Sprague in William Henry Harvey and OW Sonder: Flora Capensis, ... , Volume 4, Section 2, pages 449-450. The genus name Podranea is an anagram for Pandorea , a closely related Australian plant genus, from which the species Podranea ricasoliana was placed in its own genus.
The genus Podranea distributed from the southern tropical to southern Africa. The pink trumpet wine ( Podranea ricasoliana ) has become a neophyte as a horticulturist from Central America to tropical South America, in parts of Australia and New Zealand .
There are only two species in the genus Podranea :
- Podranea brycei (NEBr.) Sprague (Syn .: Pandorea brycei (NEBr.) Rehder ): It occurs from Malawi via Zimbabwe to Mozambique .
- Pink trumpet wine ( Podranea ricasoliana (Tanfani) Sprague , Pandorea ricasoliana (Tanfani) K.Schum. ): It occurs from Malawi, Mozambique to Zambia and in the South African provinces of Eastern Cape and KwaZulu-Natal .
The two types are quite similar. Outwardly, they only differ in the size of the luab leaves and the hairiness of the flowers. Some botanists consider them not to be independent and combine both into a single species.
use
The pink trumpet wine ( Podranea ricasoliana ) is used as an ornamental plant in tropical parks and gardens and in rooms worldwide.
