Cyanea remyi

Cyanea remyi is a rare species of flowering plant in the bellflower family known by the common name Remy's cyanea. It is endemic to Hawaii, where it is known only from the island of Kauai. [2] It is a federally listed endangered species of the United States. Like other Cyanea , it is known as haha in Hawaiian. [3]

This plant was very poorly known before 1987, with only two specimens ever having been collected, and no more occurrences of the plant seen since 1916. [2] [4] [5] Then, in 1987, the species was rediscovered when a population of up to 50 plants was found next to the Wailua River. This population was decimated by Hurricane Iniki in 1992, leaving few plants alive. In 2000, eight plants were observed, and in 2006 only a single individual remained. In the meantime other small populations were found, but several have since been destroyed in events such as flash floods. A 2010 report estimated as few as 24 individuals divided among three populations. [4]

This Hawaiian lobelioid is a shrub growing up to 2 meters tall and appearing superficially palm-like. The inflorescence bears up to 13 deep purple flowers. [2] It grows in wet forest habitat in the understory of ʻōhiʻa lehua (Metrosideros polymorpha), ohe mauka (Tetraplasandra spp.), and ʻōlapa (Cheirodendron spp.). The understory is thick with ferns, other Cyanea species, and many other species of Hawaiian endemic flora. [4]

The habitat is threatened with degradation and destruction by a number of forces, especially feral pigs and exotic plant species such as Chinese ground orchid (Phaius tankervilleae) and Koster's curse (Clidemia hirta). [4]

Kauaʻi cave wolf spider Species of spider

The Kauaʻi cave wolf spider, also known to local residents as the blind spider, is only known to occur in a few caves in a lava flow with an area of 10.5 km2 (4.1 sq mi) in the Kōloa–Poʻipū region of Kauaʻi, Hawaiian Islands, and only six populations are known to exist. While their nearest surface-dwelling relatives have large eyes, this species has completely lost its eyes. They reach a body length around 20 mm (0.8 in), and are reddish brown and completely harmless to people. Unlike most wolf spiders, it produces only 15 to 30 eggs per clutch. The female carries the egg sac in her mouthparts until the spiderlings hatch.

<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.
