Halimeda kanaloana is a species of green algae (class Ulvophyceae) in the family Halimedaceae. This species is endemic to the Maui Nui island complex (Molokai, Maui, Lanai, Oahu, and Kahoolawe).[1]
Halimeda kanaloana is characterized by a large, bulbous holdfast that anchors the specimen in sand. The basal thallus region consists of massive cylindrical to slightly flattened segments. In the central and distal regions of the thallus, the segments are large, obovoid to cuneate, and trilobed, with a median length of 9–14 mm, a width of 6–11 mm, and a thickness of 1.5-2.9 mm.[2] The medullar siphons fuse into a single unit at the segment nodes, and pores are visible connecting neighboring siphons. The median pore height, including cell walls, is 47-69 μm. The plant has 4-5 layers of utricles, with large peripheral utricles measuring 56-73 μm in diameter and 69-98 μm in height.[2] These utricles reach 42% of their maximal width at a quarter of their height and have angular corners in surface view.[2] The subperipheral utricles are markedly inflated.
