CLADOPHOROPSIS 31 
From Cladophoropsis membranacea (Ag.) Bórg., the Peruvian 
plant differs obviously in the more rigid and more slender filaments 
and in the more frequent basal septa. Its nearest affinities are 
probably to be found in the originally New Zealand Cladophoropsis 
herpestica (Mont.),* and the closely allied originally Javan Cla- 
dophoropsis Zollingeri (Kiitz.) Borg. But the Peruvian specimens 
are more slender and lack the peculiar ramuli ‘‘decussato-adnati”’ 
described by Montagne for Conferva herpestica and figured by 
Kützing for his Aegagropila Zollingeri (Tab. Рћус. 4: pl. 64. f. 11). 
The connections of these ramuli are imperfectly represented by 
Kützing, for in the authentic material in the Kützing herbarium 
(which we have seen through the kindness of Mme. A. Weber-van 
Bosse), as well as іп the type specimen of Сопјета herpestica, 
the lateral branch crowds aside the main axis and makes it falsely 
lateral and the “adnate” character is further brought about by 
the development of a rhizoid or a rhizoidal branch above the 
septum at the base of what was originally a segment of the main 
axis. Тһе strong transverse septum drawn by Kützing for his 
A. Zollingeri at two points of “адпацоп” should be deleted or 
rather should be made to lie vertically or obliquely between the 
main filament and the “adnate” or falsely lateral branch (which 
is really a direct continuation of the main filament). Тһе fila- 
ments of Conferva herpestica were described by Montagne as 300 и 
in diameter and its walls as 30 u and more thick; in the type of 
this species, now preserved in the Muséum d'Histoire Naturelle, 
which we have been permitted to examine through the courtesy of 
Professor Mangin and M. Hariot, the average diameter of the 
filaments seems to be considerably above 300 и, individual fila- 
ments often attaining a diameter of 500 и, although rhizoidal 
branches are often less than 200 и in diameter; the cell walls in 
the type are mostly from 20 to 50 y thick. 
The filaments of Kützing's Aegagropila Zollingeri, if one should 
judge from his natural-size figures, sometimes attain a diameter of 
more than 500 и, though in his enlarged figure, according to the 
scale given, they are but 150-250 и, which corresponds approxi- 
mately with the measurements given by him in his “Species Alga- 
* Comb. nov. (Conferva herpestica Mont. Prod. Phyc. Antarct. 15. 1842; Voy. 
au Pole Sud, Bot. 1:6. 1845.)
