Rubus hawaiensis

Rubus hawaiensis, also called the ʻĀkala, is one of two species (with R. macraei) commonly known as Hawaiian raspberry, endemic to Hawaii. It is found on the islands of Kauaʻi, Molokaʻi, Maui, O'ahu, and Hawaiʻi in mesic to wet forest at elevations of 600–3,070 m (1,970–10,070 ft). In most areas it is not common, but in some places (such as the upper Koʻolau Gap in Haleakalā and Laupāhoehoe Natural Area Reserve) it can be a dominant member of the understory vegetation. Although similar to the other Hawaiian species, Rubus macraei, the two are believed to be derived from separate dispersals to Hawaii....read more on Wikipedia.
