lowland plants. Letui consists of a dozen native houses, lime church and one frame house. A short distance beyond Letui the ground becomes decidedly rougher with numerous lava rocks and boulders. Then one emerges upon the old lava flow, and finds an entirely different type of growth. The tall overhanging trees cease abruptly and their place is taken by a low, open scrub about 12 to 15 feet high. The following plants were noted, the numbers referring to plant field numbers. Fuafua (100), Morinda citrifolia (noni = nogu), 139, filimoku (97), 140, 142, Mamala (specimen from Tutuila with chordate leaf and spike of small white flowers), the legumaingos shrub or small tree seen in the lowlands (143), another leguminos shrub (145), 144, 146, 147, 148, 149, 150, Osmanthus, the "rose-bud" tree collected on Tutuila, Kou (cordia subcordata); lavender flowered, small arrow-head shaped leaved morning glory (151), epiphytic plant 137, a clinging vine with large potato shaped fruit, Pandanus. Beneath is a more or less thick undergrowth of breast-high ferns (152) ki (cordyline terminalis), "maile" fern (lau ka), sida, mau kofu (167), fua sega vino (95), dodder-like orange leafless parasite, and numerous weeds and grasses (all the kinds noted in Savaii), including a prostrate matt grass. The ground rises and falls in gentle undulations. Underfoot are broken lava rocks of all sizes and in places smooth surfaced areas with radiating cracks. Mr. Stahlin, trader in Salailua, tells me that when he first crossed this flow, about 15 years ago, that it was about waist high with vegetation, and that one could see from the upper slopes to the sea without an interruption. Some eight years ago he again had occasion to cross the flow and noted that the plants had grown and were as high as his head. He further commented upon the fact that there seems to be a distinct difference between the plants on the
