| Our mass of conferva turns out to contain one of the most elegant species. |
| In the stomach of C. balnaris I found a considerable quantity of a conferva, too much, I think, to have got in accidentally. |
| The consequence has been an excessive growth of a conferva which is indigenous to these lakes and confined to them. |
| But if the conferva or parasitic fungus exceeds its allies in the above respects, it will then be dominant within its own class. |
| Polyps may be obtained at all times of the year by bringing home duckweed, conferva, and other water-plants from the ponds. |
| In the hottest water of the hot springs I collected three species of conferva. |
