Vidal y Soler, Sebastian. Catalogo metodico de las plantas lenosas silvestres y 
cultivadas observadas en la provineia de Manila, (1880) pp. 1-48. (Reprint 
from Revista de Montes 4 (1880).) 
In this work 531 species are enumerated, in which the following hew 
names appear: Pittosporum femandezii, Aegle decandra, Dysoxylum blancoi, 
Parinarium racemosum, Medinilla lagunae, Homalium barandae, and Clero- 
dendron navesianum, but most of them are scarcely more than nomina nuda. 
Many of the errors in identifications were corrected later by Vidal in his 
Rev. PI. Vase. Filip. (1886). The introduction contains much of interest 
regarding the types of Philippine forests. 
TJsteri, Alfred. Beitrage zur Kenntnis der Philippinen und ihrer Vegetation, 
mit Ausblicken auf Nachbargebiete. (Inaugural-Dissertation zur Erlangung 
der philosophischen Doktorwiirde der Unjversitat Zurich, 1905, pp. 1-166, 
with 29 text-figures and 2 plates.) 
This work contains a sketch of the geology and plant geography of the 
Philippines, meterology and climatology, notes on the islands of Guimaras, 
Cebu and Negros, a consideration of the different plant formations, notes on 
various cultivated plants, sugar culture, etc., and a catalogue of the plants 
collected, 1,431 species being enumerated from the Philippines, 1,303 from 
Java, 3 from Penang, 65 from Labuan, and about 100 from Singapore. In 
the enumeration of Philippine plants Piper usterii C. DC., and the variety 
plurifistulosum C. DC. are described, and in the Orchidaceae the name 
Dendrobium usterii Schltr. appears as a nomen nudum, later described in 
Bull. Herb. Boiss. II. 6 (1906) 458. Another new species is Selaginella 
usterii Hieron., with a very imperfect description. Under the Algae the 
following new species are described: Phormidium usterii Schmidle, and 
Myxobactron usterianum Schmidle, the latter the type of a new genus. 
Many species are credited to the Philippines for the first time. 
Warburg, 0. Pandanaceae. ( Das Pflanzenreich, 3 (1900) pp. 1-97.) 
Three genera, Sararanga, Freycinetia and Pandanus are recognized, the 
first with but a single species confined to the Solomon Islands and New 
Guinea, the other two genera widely distributed, Freycinetia with 62 species 
and Pandanus with 156. The Philippine forms recognized are Freycinetia 
ferox Warb., F. lusonensis Presl, F. sphaerocephala Gaudich., F. vidalii 
Hemsl., F. jagorii Warb., F. philippinensis Hemsl., and F. scabripes Warb., 
all endemic, and Pandanus tectorius Sol. (P. odoratissimus L. f., P. spiralis 
Blanco, P. blancoi Ktli.). The species described by Blanco, P. exaltatus, P. 
sabotan, P. gracilis, P. malatensis and P. radiedns are all considered doubtful 
species. Since the publication of Warburg’s monograph a second species of 
Sararanga (S. philippinensis) has been found in the Philippines, and several 
species of Freycinetia and Pandanus have been described as new, while most 
of the species described by Blanco have been satisfactorily disposed of.

Bataan, and in the Province of Benguet.
