Cyanea mannii

Cyanea mannii is a rare species of flowering plant in the bellflower family known by the common name Mann's cyanea. It is endemic to Hawaii, where it is known only from the island of Molokai. There are 9 occurrences with fewer than 3000 plants remaining. [1] It is a federally listed endangered species. Like other Cyanea it is known as haha in Hawaiian. [2]

This Hawaiian lobelioid is a shrub growing 1.5 to 3 meters tall with a palmlike cluster of leaves at the top of the stem. The inflorescence produces purple flowers. The plant grows in moist forest habitat. Threats to the species include degradation of this habitat by feral pigs and rodents. [1]

Hawaiian lobelioids

The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, subfamily Lobelioideae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera involved can be broadly separated based on growth habit: Clermontia are typically branched shrubs or small trees, up to 7 metres (23 ft) tall, with fleshy fruits; Cyanea and Delissea are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; Lobelia and Trematolobelia have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar Brighamia have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits. The relationships among the genera and sections remains unsettled as of April 2022.

<i>Cyanea</i> (plant) Genus of flowering plants

Cyanea is a genus of flowering plants in the family Campanulaceae. The name Cyanea in Hawaiian is hāhā. These Hawaiian lobelioids are endemic to Hawaii with over 90% of Cyanea species are found only on one island in the Hawaiian chain. They grow in moist and wet forest habitat and are largely pollinated by birds such as the Hawaiian honeycreepers, and the seeds are dispersed by birds that take the fruits. Most Cyanea are trees with few branches or none. The inflorescence is a raceme of 4 to 45 flowers which grows from the leaf axils. The fruit is a fleshy berry. There have been several theories regarding the evolution of large prickles on plants endemic to islands that lack any mammalian or reptilian herbivores. One such theory suggests that the prickles are a defense against herbivory by the moa-nalo, a few taxa of flightless ducks that went extinct on the islands within the last 1600 years.
