Notes on the flora of Gardner Island by C. R. Long Thirty species of vascular plants have been collected and/or recorded from Gardner Island. The majority of the introduced species (designated by an asterisk) were probably brought from the Gilbert Islands in the late 1930's by settlers. Vascular plants were collected by the U. S. Exploring Expedition in 1840 (one sheet of this collection was located in the United States National Herbarium); and, by C. R. Long in October 1964. Gramineae Cenchrus echinatus L.* Long 2467 (UH). The burrgrass forms heavy stands in coral rubble of the abandoned village and is naturalizing along paths of the north and the south portions. Digitaria pacifica Stapf.* Long 2476, 2504, 2515 (UH). In coral gravel of roadway in village and on the east portion of the southwest island. This species appears to be naturalizing widely over the island. Eragrostis tenella (Link.) Beauv.* Long 2471 (UH). In coral gravel of the abandoned village and adjacent Cocos groves. Lepturus repens (Forst.) R. Br. Long 2465, 2472, 2489, 2493, 2508 (UH). Common in sandy soils over the island. Cyperaceae Fimbristylis cymosa R. Br. Long 2459, 2505 (UH). In a well watered depression of coral rubble on the southwest island among dead Cocos. Possibly introduced. Palmae Cocos nucifera L. Groves occur on the west and south sides the majority of which have been planted in modern times. Between 1938 and 1940, 8,000 coconuts had been planted (Laxton, 1951). Amaryllidaceae Crinum asiaticum L.* Long 2525 (UH). Ornamental near abandoned huts in village. Urticaceae Fleurya ruderalis (Forst. f.) Gaud. ex Wedd. Long 2502 (UH). On coralline hardpan, north side, under shade of Pisonia grove, scarce.
