Dionaea
June 25 /73/ Compared 2 tentacles, one after 1O. 20' & the other after 2O 30' & both showed some segregation, when viewed in water, (but seg. not visible when dry). —
I cd. see no difference, but them these filaments were colourless.
June 30. Touched 2 filaments & left 2 untouched & after 25O compared them, but cd perceive no difference in segregation: thy were, however, very pale filaments, — I saw, however, distinctly, the flowing of protoplasm round walls of cells
The above leaf I observed had caught a fly, (not very small), on the 20th, perhaps several day before & on the 25' was well open again, but I think this leaf was in rather feeble state.
