CAULERPACEAE. 609 



6. Caulerpa Freycinetii Ag. Sp. Alg. 1: 44G. 1822. 



On corals in shallow water. Atwood Cay : Guadeloupe ; Red Sea ; Pacific Ocean. 

 Type from the Mariana Islands. 



The Atwood Cay specimens apparently belong with var. pcctinata Web.-v. 

 Bosse, differing from the type in being only slightly twisted and in the more regular 

 and better developed marginal teeth ; it seems to approach closely certain conditions 

 of C. cupressoides.

On a sandy bottom in shallow water. New Providence (south shore) : Florida. 

 Type from Key West, Florida. 



S. Caulerpa paspaloides (Bory) Grev. Alg. Brit. Ixiv. 1830. 



Chauvinia paspaloides Bory, Voy. Coquille, Bot. Crypt. 205. pi. 23. f. 1. 

 1829. 



On a sandy bottom, mostly in 1-40 dm. of water. New Providence (south 

 shore), Long Bank, Abaco, Green Cay, and Great Bahama: Florida and Cuba. 

 Type from the Bahama Islands. 



The type is characterized by having its ramuli in (2)3 or 4 ranks, the spikes 

 distinctly alate or strongly angled when living and shaggy when dry, the ramelli 

 pectinately secund, and always much shorter than the axis from which they spring. 

 In addition to the type form, there are in the Bahamas two other strongly marked 

 forms, varieties, or subspecies, which appear to be locally distinct, that is, they 

 seem to occur with little if any local intergrading or intermingling, though growing 

 in similar habitats ; however, when plants from various localities are compared, it 

 seems difficult to maintain these three groups as distinct species.

Chauvinia phleoides Bory, Voy. Coquille, Bot. Crypt. 206. pi. S3. f. 2. 

 1829. 



On a sandy bottom in shallow water. Exuma Chain. Type from the Bahama 

 Islands. Apparently endemic. 



Differs from the typical C. paspaloides in having its ramuli in 6-10 ranks, the 

 spikes slightly angular or strongly ribbed when living, more or less shaggy when 

 dry, the ramelli mostly pinnately distichous or occasionally subsecund.

On a sandy bottom in shallow water. Rose Island, Long Island, Exuma Chain, 

 and Ragged Island. Type from the Bahama Islands. Apparently endemic. 



Differs from the typical C. paspaloides and C. paspaloides phleoides in having 

 its ramuli in 816 ranks, the spikes dense and wholly terete or very lightly ribbed, 

 the ramelli pinnately distichous and corymbose, the lower ramelli as long or nearly 

 as long as the axis from which they spring.
