Metabolic Effects on Ion Fluxes inTolypella intricata
Journal of Experimental Botany, 1968The uptake of CI ions by cells of Tolypella intricata is greatly increased by light, and must be an active process. K ions in the cells (at 90-110 mM concentration) are in approximate electrochemical equilibrium with the external solution, but the K influx is affected (directly or indirectly) by cellular metabolism.

Upper Cretaceous Lychnothamnus, Nitella and Tolypella (Charophyta) from Zampal, Argentina
Cretaceous Research, 2010Abstract Fossil gyrogonite and oosporangia remains belonging to the three extant Charoideae genera Lychnothamnus, Nitella and Tolypella are infrequent in pre-Tertiary sediments. The present record is striking owing to the geographical provenance of these microfossils at the same locality in west-central Argentina that formed part of the continent of ...

TWO NEW SPECIES OF TOLYPELLA(CHARACEAE) FROM NORTH AMERICA1,2
Journal of Phycology, 1973SUMMARYTwo new species of the genus Tolypella (Characeae)–T. boldii Sawa sp. nov. and T. canadensis Sawa sp. nov.–were discovered in Texas, U.S.A., and Ontario, Canada, respectively. The species are recognized as additional members to the section Acutifolia because of the small and conical branchlet end cell and the oospore with a single basal ...
