Geranium arboreum is a rare species of geranium known by the common names Hawaiian red-flowered geranium and Hawaii red cranesbill. It is endemic to Hawaii, where it is known only from the island of Maui.[1] It was federally listed as an endangered species in 1992.[2] Like other Hawaiian geraniums, this plant is known as hinahina and nohoanu.[3]
This plant is a shrub which can reach 4 meters in height. The leaves have green, toothed blades up to 3.8 centimeters long. The flowers are red or magenta. The upper petals are erect, but the lower two are curved under.[2] The shape of the flower indicates it is pollinated by birds, which is unique among the geraniums.[1][2]
This plant grows in gulches on the slopes of the volcano Haleakalā. There are no more than 500 individuals left.[1]
The main threat to this species is the degradation of its habitat by grazing cattle, feral pigs, and non-native plant species invading the area.[2]

Es un arbusto que puede alcanzar los 4 metros de altura. Las hojas tienen color verde, las láminas de las hojas dentadas de hasta 3,8 centímetros de largo. Las flores son de color rojo o magenta. Los pétalos superiores son erectos, pero las dos inferiores se curvan bajo. La forma de la flor indica que está polinizada por aves, siendo la única entre los geranios.[2][3]
Esta planta crece en quebradas en las laderas del volcán Haleakala. No hay más de 500 plantas en la parte izquierda.[2]
La principal amenaza para esta especie es la degradación de su hábitat por el pastoreo de ganado vacuno, los cerdos salvajes y especies de plantas no nativas que invaden la zona[3]
