E. whitneyi var. caumii (from the Hawaiian Leeward) is recognized as distinct the taxon formerly found on Baker Island would be var. whitneyi. This species has not been collected since 1924. Christophersen found this native grass "on the beach" which suggests that this species is a wave carried adventive. Lepturus repens (Forst.) R. Br. Christophersen 31 (BISH), Coman s. n. (BISH), Bryan 1323 (BISH)? Marshall 10, 11 (USNM), Long 2151, 2153, 2162, 2372, 2387 (UH). The Pacific bunchgrass is found inside the beach ridge and most commonly on the flat interior area. Thick clumps found along the west beach ridge form pure stands. First collected in 1924 from "beach sand" by Christophersen and later by Bryan from the central basin forming an association with Boerhavia and Portulaca. Setaria verticellata (L.) Beauv. Long 2150 (UH). Four clumps were found on the southwest side in sand. Probably introduced during the Second World War and not spreading. Cyperaceae Fimbristylis cymosa R. Br. Christophersen 32 (BISH) as F. pycnocephala Hbd. and F. cymosa var. microcephala F. Brown, Bryan s. n. (BISH) as F. cymosa var. microcephala F. Brown, Long 2399 (UH). Reported from "pockets in conglomerate bedrock" (Christophersen) and from "moist spot amid dunes" (Bryan). Found in 1964 in soil pockets of steel matting of runway built during the Second World War. Long's specimen is not identical with the earlier collections and may represent a later introduction. Palmae Cocos nucifera L. An attempt was made to introduce this species during the 1930's. While the trees seemed to thrive under cultivation they eventually succumbed to the ravages of rats and crabs (Rodman, 1935; Pianala, 1936). Nyctaginaceae Boerhavia sp. Christophersen 37 (BISH) as B. tetrandra Forst., Bryan 1324 (BISH) as B. tetrandra Forst., Marshall 12 (USNM), Long 2152, 2159, 2161, 2163, 2366, 2373, 2377, 2401 (UH). This native herb is common over the island especially in sandy soils. The taxonomy of this genus in the central Pacific is confused and until studies now underway are completed it seems best not to designate a specific epithet. This white flowered species may be identical to the probable new taxon referred to by Fosberg and as yet unnamed (Fosberg, 1959);
