sand. The stems of Triumfetta are to 10 m. in length with upright sprouts. Not common, probably a wave carried adventive. Found along the west side with Lepturus and Digitaria, less apparent elsewhere At the edge of hardpan just above the lagoon flat on the midwest side. Also occurs at the bottom of a shallow depression N of the guano workings. Not common on Enderbury but commonly distributed in the Phoenix and Line islands. Small trees occur in restricted groves on the S and W sides often with Tournefortia. Used as nesting sites by the redfooted booby and greater frigatebird. Small trees found on the W and S sides with Cordia used as nest sites by the species cited above. Much of the groves on the We side are composed of dead wood. Heavy concentrations of nesting birds combined with salt spray (especially with Cordia) restricts growth. Green sprouts in the area of nest platforms were torn and guano covered. Accumulations of guano found at the surface under these groves but no evidence of phosphatization such as occurs on wet islands under Pisonia was observed. Fifteen species of vascular plants have been recorded from Enderbury Island. Ten of these are considered native, two are problematical introductions and three are known introductions since the European discovery of the island. Only Digitaria of the introduced plants appears to have naturalized to any extent. Collections of vascular plants from Enderbury Island have been made by the following: E. H. Bryan, Jr., March 1924 and July 1938; S. H. Lamb, 1938 March 1938; C. R. Long, November 1964; P. Woodward, February 1965. July and
