C.R. Long 1964 Addenda to the Report of C. D. Hackman, February - March ATF, 1964. Plants. Enderbury Island February 27, 1964, Sida sp. - Sida fallax Walp. or close. The Sida specimens collected from the Phoenix Islands are partially indistinguishable from Sida cordifolia L. and Sida fallax Walp. A nomenclatorial change or a new taxa may be indicated. Cordia sp. - probably Cordia subsordata Lam. but possible Cordia sebestena L. Dodder sp. - Cassytha filiformis L. February 28, 1964 - "grass is quite small and easily overlooked" - Eragrostis whitneyi Fosb. var. Canton Island March 2, 1964 - Scaevola taccada or Scaevola frutescens (Mill.) Krause for Scaevola sp. The former name is the oldest which may be applied to material commonly called frutescens by most authors. However, the Scaevola in the Phoenix and Line Islands varies from the Scaevola found to the north and new taxa are indicated with the proper nomenclatorial changes.- "several clumps of the species of grass we had discovered near the lagoon on Enderbury"- Eragrostis whitneyi Fosb. var. There are two varieties of this species. Jarvis Island March 14, 1964 Sida sp.-Sida fallax Walp: - see above February 27 note Boerhaavia sp. -B . diffusa L. var. tetrandra Heimerl. - but the status of these color variations also noted on Hull Islnad indicate new taxa. Portulaca sp. - Portulaca lutea Sol. March 15, 1964 "The small bunchgrass-" - Eragrostis whitneyi Fosb. var. "ragweed plant-" - Chenopodium ambrosioides L. Illustrations: -7.

Suriana maritima L.; 25. Heliotropium anomalum H. and A.; 26. Scaevola taccada 27. Acanthaceae (we are having difficulty keying this to genus and species level- it is not grown in Hawaii and may have been introduced from the southwest Pacific area); 28.
