CERAMIACEAE 149 
Codium, has been reported from Peru under the name of Rhodo- 
peltis Geyleri Asken. (Bot. Morph. Studien 42. f. 61-68. 1872), 
the identity of which the originally South African Placophora 
Binderi has been vouched for by Goebel (Flora 72:3. 1889) and 
by Falkenberg (Rhodomelaceen 338. 1901). We have not been 
able to discover anything like it on the Peruvian specimens of 
Codium collected by Dr. Coker.

The specimen is apparently sterile, as was also the type of 
Griffithsia chilensis. The plants are shorter, more cespitose, and 
less straggling than the originals of Montagne and of Kützing. 
The filaments are mostly 250-350 и in diameter, but are often 
500 и or more under the dichotomies; the apices are 160-250 u 
in diameter. Under no. 149 p.p., same locality and date, is a 
mere fragment, probably of the same species, but commonly 
more swollen at the septa, at or near which the plant is often 
rhiziniferous. These rhizoids are sometimes enlarged and hap- 
terous at apex and the filaments are thereby more or less coherent. 
The filaments of this no. 149 attain a diameter of 600-700 џ at Ше 
septa and occasionally 1 mm. under the di- or tri-chotomies. 
Griffithsia chilensis has been attributed by Montagne (Syll. 
Crypt. 447. 1856) to Peru as well as to Chile. Whether it is the 
same as the plant from Cobija (then in Peru, now in Chile) that 
һе had previously (Fl. Boliv. 7. 1839) referred to С. setacea, we 
do not know. Kiitzing, at the place of original publication of 
G. chilensis, gave it a position immediately following G. setacea.
