Plant of a foliaceous Jungermannia, J. bidentata, nat size. PLATE II. Fig. 1. Fructification of the genus Clwra. a, The nucule ; 5, The globule; c, The bracteas 2. The nucule more highly magnified. 3. Segment of a frond of Fucrn vesiculosus, nat. size, a, The recep- tacle in which the tubercles of the fructification are imbedded.— 4. Granules and filaments contained in the tubercles 5. The air-vesicles of the frond. 6. Segment of a frond of Delesseria alata, nat. size.—7. One kind of fruc- tification, consisting of naked granules 8. The second kind, a tubercle containing sporules—9. The sporules or granules. 10. Part of a frond of Sphcerococcus membranifolius, nat. size 11. The tubercles, which are either sessile on the frond, or shortly pedicel- late on the stipes or margin—12. The granules. 13. Portion of a frond of Ptilota plumosa, shewing the fructification 'na- ked at the base of an involucre. 14. Summit of a frond of Gigartina subfusca, shewing the innate tu- bercles. 15.
