In the February part of the proceedings of the American Academy, Mr. Sereno Watson gives us three articles; one on the Flora of Guadalupe - a small island of the coast of Lower California; another, a list of plants collected on the same island by Dr. Ed, Palmer; the third, descriptions of new plants, chiefly Californian. The last contains many things that cultivators will be on the look-out for. There are three new Lupines, all blue flowered. Four new species of clover gives Mr. Watson a chance to revise the whole of North American Trifoliums. He makes 39 species in all. Sophora Arizonica and Parkinsonia Tor-reyana should make valuable shrubs for the Southern States. The beautiful family of annuals, Mentzelia, receives a new addition in M. dispersa. A new dogwood from California is Cornus Torreyi; it has loose cymes of white berries, with the stones curiously crowned with tubercles. Keference is also made to a curious Palm, with leaves as thready as the well-known Yucca filamentosa, and of which we have had specimens sent us by Mr. Rock and others.
Mr. Watson says it is a Brahea and " introduced into cultivation as B. filamentosa." He describes two allied species - one from Guadalupe Island as B edulis, the other, if a real Brahea, as B. armata, from 80 miles below San Diego. A Cypripedium, collected by many botanists in past years, and near C. parviflorum, is now made C. occidentale.
A small white-flowered shrub from Southern Arizona, allied to spinea, is made Vauquelinia Torreyi.
Guadalupe Island is 26 miles by 10, and is 100 miles west of the coast of Lower California. One would suppose from its southern latitude that the plants would be of a tender character, corresponding with that on the mainland, but a glance at the list of 119 given here shows a comparatively hardy class. But this is accounted for when we read that the island is in the midst of the current, which on that side flows down from the North seas; and this should make the flora of a somewhat similar character, as regards hardiness, to that of England, which receives the warmth of the northward flowing or gulf stream. Still the winters are not quite as severe as the English, and the summers are often hot and dry. The Palm, Brahea edulis, grows 40 feet high. Only six grasses are in the enumerated list.
