Studies in Mexican and Central American Plants

The author encountered several trees of an apparently new Ulmus growing in a moist canyon in the mountains of northern Coahuila. The locality has an altitude of probably four or five thousand feet. The twig and foliage characters of the new material can hardly be used to distinguish it from Ulmus divaricata C. H. Mull.2 which occurs in similar habitats in central Nuevo Leon and has a similar habit. The trees observed in Coahuila were all barren of flowers and fruit at the time, but a single fallen fruit and some peduncles were found after a tedious search in debris-filled crevices. The differences exhibited by this single fruit (Fig. 1, B) are so profound that it is difficult to imagine that they might have arisen as the result of pathology, simple mutation, or ecological variation. The more numerous available fruits of U. divaricata exhibit a normal variation in form (e.g., about ten percent of the fruits have erect style branches rather than divergent ones), but in no case is the disposition of the principal veins and reticulum noticeably different from the illustration (Fig. 1, A) or in any way similar to the material here described as a new species.

Additions to the Botanical Collections

Miss E. HOMBERSLEY has given to the Department of Botany of the Natural History Museum 882 paintings of British flowering plants by Miss Ellen Hawkins, who died in 1864. The paintings are of considerable merit and are accompanied by descriptions, written on the opposite page of the double sheet, which give interesting details and information. Miss Hawkins wrote the botanical appendix to Robertson's “Handbook to the Peak”(1854). Mr. Reginald Cory has presented the original manuscript and drawings of the “Tabular Distribution of the Vegetable Kingdom” by John Stuart, third Earl of Bute. The Department already possesses many plants purchased at the Earl of Bute's sale in 1794. Prof. John Percival has presented a set of all the known species of Ægilops. Prof. Percival's knowledge of this difficult genus of grasses makes the set of special value. Among the purchases there is a further set of H. J. Schlieben's Tanganyika plants and 668 Brazilian and Mexican plants collected by Y. Mexia and 248 drawings of liverworts (Jubuleæ) by Fr. Verdoorn.

Trees and Shrubs of Mexico

THE first instalment of an account of the woody plants of Mexico, by Mr. Paul C. Standley, is issued as vol. xxiii., part i, of the Contributions from the United States National Herbarium. The work is based upon the extensive series of Mexican plants in that institution. The botanical features of Mexico have attracted attention from the days of the earliest explorers, and many botanists have visited the country within the last hundred years, yet the flora is still but imperfectly known. The plant formations are remarkably diverse, including the wet tropical forests of the southern lowlands, the temperate deciduous and coniferous forests of the central plateau and of the ranges of the Sierra Madre, the alpine zones of the high peaks like Orizaba and Popocatepetl, and the great barren or cactus deserts in the northern States. For anything approaching a complete account of the flora of Mexico we have hitherto had to rely on Dr. Hemsley's list in the “Biologia Centrali-Americana,” published nearly forty years ago; much botanical work has been done in the country since that time, and a descriptive flora which will give an account of present knowledge and serve as a starting-point for further work is a desideratum.
