98 GIGARTINACEAE 
(sterile ?) originally described by Bory and supposed to have been 
collected in Chile, though suspected by Bory to have come, in 
reality, from the Society Islands. The type of Gelidium filicinum 
in the herbarium of the Muséum d'Histoire Naturelle consists 
according to М. Hariot (in litt.) of a single large plant about 11 
ст. broad and 8 cm. high and a smaller, apparently identical 
fragment marked a. On the sheet is written in Bory’s hand: 
“donné comme de la Concepcion au Chili par Durville; mais 
l'échantillon a vient bien évidemment de Borabora, ой le recueillit 
Lesson, 1825." In some respects the fragments from the turtle's 
stomach suggest also the Chilean plant described by J. Agardh 
as G. lingulatum and figured by Kützing, but they are more regu- 
larly and closely bi-tripinnate than that and there is no evidence 
that the fertile branches are ever lobed or compound.
