Abstract: Twenty-three stream segments (seven on O'ahu, eight on Kaua'i, and eight on Hawai'i) were sampled for macroalgae in the Hawaiian Islands. Stream segments ranged greatly in size from 1.2 to 40 m in width. Water temperature was uniformly warm (17-24[degrees]C), but other chemical parameters differed from site to site (pH 5.5-8.9, specific conductance 20-200 [micro]S * [cm.sup.-1]). Mean species richness per site was 3.9 with one to eight species collected per stream segment. Ninety populations of 42 infrageneric taxa were identified front the Cyanobacteria (19), Chlorophyta (17), Rhodophyta (3), and Chrysophyta (3). The most abundant taxa were Spirogyra sp. 1, ...
