Cyanea magnicalyx is an extremely rare plant species from the subfamily of the lobelia family (Lobelioideae) within the family of the bellflower family (Campanulaceae).
description
Cyanea magnicalyx is a shrub that branches out at the bottom. This species reaches a height of 1.5 to 3 m. The elliptical leaves are green on the top and light green on the underside. The leaf margin is pinnate towards the tip and pinnate connected to the leaf base.
The racemose inflorescence contains six to 15 flowers. The corolla is yellowish white with purple vertical stripes. All five anthers have tufts of hair. The fruits are yellowish berries .
Occurrence and status
Cyanea magnicalyx is endemic to the west of the island of Maui . This species occurs in semi-arid forests or wet forests at altitudes up to 490 meters. There are two populations with a total of six specimens. One mature shrub exists in Kaluanui Gorge, two mature shrubs and three young plants are found in ʻIao Valley State Park.
The main threat is the displacement by invasive plant species such as the strawberry guava ( Psidium cattleianum ), Rubus rosifolius , Oplismenus hirtellus , Rubus argutus , Tibouchina herbacea and the African tulip tree ( Spathodea campanulata ). Other reasons for the rarity are landslides , looting of the fruits by rats and feral pigs, floods and the greatly reduced reproductive activity due to the few remaining individuals.
Taxonomy
The species Cyanea magnicalyx was first described in 2004 by Thomas G. Lammers (born 1955).
