 BOTANY The Loe Pool, the largest sheet of inland water in the county, has yielded a number of rare and local plants. To the keen regret of west-country botanists a recent raising of the water level has resulted in the disappearance of Corrigiola littoralis ; but almost at the very time of that unfortunate occurrence a genuine solace was forthcoming in the discovery by the Rev. G. R. Bullock- Webster of Nitella hyalina, the first and still the only British record for a particu- larly graceful plant. Castalia speciosa, Elatine hexandra, Pyrus tormina/is, Bidens cernua, B. tripartita, Mimulus Langsdorffii, Sibthorpia europtsa, Utricularia minor, Scutellaria galericulata, Melittis Melissophyllum, Chenopodium rubrum var. pseudo-botryoides, Euphorbia portlandica, Ruscus aculeatus, Juncus pygm&us, Polygonum maritimum, Potamogeton perfo/iatus, Ruppia spiralis, R. rostel/ata, ZannicMiia palustris, Eleocharis acicularis, R. Br., are but a few of the plants to be found on, in, or adjacent to the Pool. SPECIES AND VARIETIES WORTH NOTING IN THE LIZARD DISTRICT Ranunculus Baudotii, Godr. tripartitus, DC. Lingua, Linn.
