Not illustrated. 1896 edition. Excerpt: least 2800 ft. alt. I think, however, that the hill plant has filaments relatively shorter to the anthers than the low-ground form. All the specimens I have examined in Skye, Eigg, and the north of Mull, have resembled the mainland plant with six stamens and long filaments. As the floating form has only occasional chances of flowering, I have examined comparatively few specimens, but the great majority had stamens and length of filaments in the same proportion as the land plant; though I have noticed on a few occasions three stamens, and filaments and anthers of about equal length. The submerged capillary-leaved form which grows in large masses at the bottom of lochs very rarely has a chance of flowering, but the few examples I have seen in flower have all had six stamens with filaments longer than the anthers. This last form is very unlike a /uncus. Scirpus fluitans, L., which grows in similar patches on the bottom of lochs and stagnant pools, resembles it a good deal, as in such situations it also has long capillary leaves.--Symers M. Macvicar.
