THE ERUPTION IN HITAKA CRATER, ISLAND OF HAWAII 4a Otte & Isa Degener Hiiaka* Crater, a minor pit crater in Hawaii Volcanoes National Park and named in honor of the sister of the Hawaiian Volcano God- dess Pele, showed activity at 6.45 A.M., August 22, 1968, the first time within the memory of man. Clouds of acrid fumes rose into the air to be carried by the trade wind in a southwesterly direction. Though the activity culminated in a 75~foot lava fountain, and a pool of lava 300 feet in circumference accumulated in the crater before draining away underground, the area became quiescent before noon of the same day. On August 2) we drove along the Chain-of-Craters Road, turning into the side road leading to Ainahou Ranch. For a distance of about a mile along this road or up to one and a half miles leeward as the crow flies from Hiiaka Crater, we noted the following common plants affected by the fumes: Sadleria cyatheoides ( endemic), copodium cernuum var. crassifolium (native), Arundina bambusi- folia (naturalized weed), Santalum paniculatum (endemic), Osteo- meles anthyllidifolia (native), Dodonaea viscosa s.l. (native), Styphelia tameiameiae (endemic), Vaccinium reticulatum (endemic), Buddleja asiatica (naturalized weed), Pluchea odorata (naturalized weed), and Railliardia ciliolata var. laxiflora (endemic). Their leaves showed signs of wilting andor yellowing and often death. What impressed us was that the endemic Metrosideros, often in- correctly considered conspecific with the New Zealand M. collina, showed no damage from the fumes at all, apparently having devel- oped an efficient immunity over the ages. *Incorrectly spelled "Heake" on the United States Geological Survey map, edition of 1933. 10 a : E PLANTS OF HAWAII $l = } fs) 4 copyright reserved 6 EX HERBARIUM OTTO DEGENER 32,437 3 os font 27 Lh Gs , [four ee, COLLECTED BY OTTO DEGENER AND ISA DEGENER ROYAL BOTANIC GARDEN o EDINBURGH : A é z ‘‘PLANTS HAW.
