Summary:

Six alien species were Malabar melastome (Melastoma candidum), banana poka (Passiflora mollissima), fountain grass (Pennisetum setaceum), strawberry guava (Psidium cattleianum), yellow Himalayan raspberry (Rubus ellipticus),and German ivy (Senecio mikanioides). The distribution, elevation, and median annual rainfall of the six species in upland habitats on the island of Hawaii are described based on data collected at 7,864 sampling stations along 117 transects within a 1,930 square miles study area in 1976-1981. Three species, strawberry guava, fountain grass, and banana poka, were widely distributed throughout the study area, while the remaining three species were found on less than 2% of the stations sampled. The habitats with median annual rainfall in low-elevation areas were found to be consistently invaded by three or more of the species. Portions of the two largest vegetation units, ohia (Metrosideros polymorpha) rain forest, and ohia-koa (Acacia koa) rain forest, were colonized by five of the six species analyzed.
