Plants. 
Enderbury Island 
February 27, 1964, Sida sp. - Sida fall ax Walp. or close. The Sida specimens 
collected from the Phoenix Islands are partially indistinguishable from 
Sida cordlfolia 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 filiform!s L. .

February 28, 1964 - ? ’grass is quite small and easily overlooked” - 
Eragrostis whitneyi Fosb. Var. 
Canton Island 
March 2, 1964 - Scaevola taccada or Scaevola finite scens (Mill.) Krause for Scaevola 
sp. The former name is the oldest which may be applied to material r.nmmonly cal 1 pd 
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.- 11 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 speeias. 
Jarvis Island 
March 14, 1964 
Sida sp. -Sida fallax Walp. - .see above February 27 note
