Penzance LIVERWORTS (Hepatic*) Although the Cornish list of Hepaticse is not so rich as that of Devonshire, it contains some very rare species not recorded for the latter county. The rarest of these is perhaps Scalia Hookeri, found by Mr. W. Curnow on Chy-an-hal Moor, whence it has since disappeared. This species had previously only been found in the New Forest. It grows intermixed with Aneura multifida and is best recognized by its fleshy rooting base. Petalophyllum Ralfsii (first discovered by Dr. Ralfs) is another, less rare, but by no means common, occurring usually in the damp hollows of sand dunes in company with Pallavicinia Hibernica and Fossombronia angulosa. It was formerly found between Loggans Mill and Treeve, Phillack, and between Hayle Causeway and St. Erth, but the locality was subsequently destroyed. It has since been found on sand flats at Gwithian, and it is hoped that Pallavicinia Hibernica var. Wilson- iana, which was destroyed in the former localities, may again be detected elsewhere. The rare Lejeunia calyptrifolia, formerly found at Trevayler Bottom, has now disappeared. Several species not commonly found fertile occur in that state in Cornwall, of which may be mentioned Plagiochila asplenioides, Lunularia vu/garis, Kantia arguta, Jungermannia inflata, Lepidozia setacea, Antboceros Icevis, A. punctatus, and Mefzgeria furcata. On the other hand some common species appear to be rare, or infertile : Marchantia polymorpha and Reboulia bemispbcerica are rare, and Fegatella cornea has not been noticed in fructification, although the male receptacles have been found occasionally. There is little doubt that care- ful search along the damp rocks near the sea would reveal several more species, especially those of a southern type. Targionia Micbelii should certainly occur, as it is not infrequent around Plymouth Sound. Mr. Holmes also found a spiny Riccia, probably R. ciliifera, Link, on cliffs near Tintagel. It has been identified as R. tumida by Mrs. Tindall, but it is not purplish underneath as in that species. Riccia crystallina is not unlikely to occur on marshes near the sea. Dumortiera irrigua, which occurs in Devon, near Ilfracombe and Torquay, should also be found in Cornwall by streams near the sea. Mr. W. Curnow paid especial 79
