A propos du livre

Présentation de l'éditeur

There are definitely known from the Philippines at the present time about 6,500 species of flowering plants and vascular cryptogams, distributed into about 1,450 genera, in 200 families. Many of the species are of very local occurrence, while others are confined to medium and higher altitudes in the mountains, and are hence never seen by the average resident of the Archipelago. The flora of the coastal region, especially of the populated areas, is remarkably uniform, practically the same forms being found in and about such towns as Zamboanga, Cebu, Iloilo, Aparri, etc., as are found about Manila, so that for all practical purposes a flora of the vicinity of Manila is also a nearly complete flora for most inhabited regions at low altitudes in all parts of the Archipelago. Accordingly while most of the plants encountered in the settled areas at low altitudes will be found to be described in the present work, it will be found to be of little value for the determination of specimens collected in the forests and on the mountains.

In compiling this work an attempt has been made to include all the species of vascular cryptogams and flowering plants growing naturally within the area selected, as well as most of the cultivated forms, both of Philippine and of foreign origin. The area covered extends from a point north of Manila on the bay shore at Malabon, inland through Balintuac, San Francisco del Monte etc., to Pasig, thence to the town of Paranaque on the bay shore south of Manila, covering approximately 100 square kilometers (about 40 square miles). No part of the area exceeds an altitude of 50 meters, and no part of it approaches primeval conditions, the vegetation of the entire region having been profoundly altered by the presence of man.

This "Flora" is based on botanical material preserved in the herbarium of the Bureau of Science, supplemented by an extensive series of notes covering a period of exploration of the area extending over eighteen months. Undoubtedly future intensive exploration will add a considerable number of species to the list of indigenous ones, while the list of introduced and cultivated species is being very rapidly increased. Scattered individuals of any species found in neighboring provinces at low altitudes are to be expected within our area, and as a matter of fact a considerable number of species are included in the present work on the basis of single plants observed within the region covered by it. In early botanical works, various monographs etc., many Philippine species are credited to the Archipelago as having been collected in Manila; very many of these references are erroneous, the term Manila having been used more or less synonymously with the Philippines. Most of the species so referred to were collected in regions remote from the city, and very many of them on other islands than Luzon. No species has been included unless specimens have been seen from the area selected.
