trip was made inland to Laguna de Bay to Santa Cruz, Majayjay, Mount Ba- 
najao, and Los Banos; later visiting Caldera, Mindanao, Jolo and Marongas 
■ Islet, and the Mangsee Islands. About 500 species of plants are enumerated 
from the Philippines, including ferns, but for most part with identifications 
to the genus or family only. The book ends abruptly at page 524 in the list 
of Mangsee (Mangsi) plants, and apparently no more was published. Some 
of the specimens mentioned are not to be found in the United States National 
Herbarium, the Gray Herbarium nor in the Herbarium of Columbia Univer- 
sity. (See Merrill, the Philippine Plants collected by the Wilkes United 
States Exploring Expedition, This Journal, Botany, 3 (1908) 73.) 
Planclion, J. E. Prodromus monographiae ordinis Connaraeearum. ( Linnaea 23 
(1850) pp. 409-442.) 
Five species are described from the Philippines, all based on material 
collected by Cuming; Rourea multi flora , R. heterophylla, Gonnarus neurocalyx, 
C. polyanthus, and G. obtusifolius. 
Reg'el, E. Cycas liuminiana Porte. (Gartenflora 12 (1863) pp. 10-17.) 
The above Philippine species is figured and described. 
Robinson, C. B. Some Features of the Mountain Flora of the Philippines. 
(Journ. N. Y. Bot. Card. 8 (1907) pp. 113-117.) 
A general discussion of the highland flora of the Philippines and some of 
its affinities, the following northern types being credited to Luzon for the 
first time, Boenwinghausenia alb i- flora Reichb. f., Thesium psilotoides Hanee, 
Anaphalis adnata DC., and A. contorta Hook. f. 
Robinson, C. B. Ipomoea triloba L. in the Philippines. (Torreya 7 (1897) 
pp. 78-80.) 
The above Linnean species, a native of tropical America is credited to the 
Philippines as an introduced plant, and to it is reduced Ipomoea blancoi 
Clioisy, based on Convolvulus dentatus Blanco, non Vahl. Distribution, 
synonymy and citation of specimens are given. 
Rolfe, R. A. Donax and Schumannianthus. (Journ. Bot. 45 (1907) pp. 242- 
244.) 
Three species of Donax and two of Schumannianthus are considered and 
full synonymy is gi'ven, one species only extending to the Philippines, Donax 
cannaeformis (Forst. f. ) Rolfe, to which must be referred Maranta arundina- 
cea Blanco, non Linn., M. dichotoma Naves, non Wall., Glinogyne grandis 
Vidal, and numerous Philippine specimens referred to Donax arundastrum 
Lour., which species was erroneously interpreted by Schumann, and does not 
extend to the Philippines. 
Sehmidle, W. Einige neue Algen aus Java und den Philippinen (gesammelt von 
A. Usteri, Zurich). (Hedivigia 43 (1904) pp. 414-415.) 
Four species are described, one from Java, one from Labuan, and the 
following from the Philippines, Phormidium usterii and Myxobactron usteria- 
num. The same sjjecies appear again with short descriptions, the latter with 
a figure, in Usteri Beitrage Kennt. Philip, und Hirer Vegetation (1905) pp. 
136-139, several other species of Philippine Algae being also enumerated in 
the latter place. 
Schulz, 0. E. Erythroxylaceae. (Das Pflanzenreich 29 (1907) pp. 1-170.) 
In this monograph of the family two genera are recognized, Erythroxylum 
P. Br., and Aneulophus Bentli., the former with 193 species, widely dis- 
tributed in the tropics of the world, and the latter monotypic and African. 
Erythroxylum is represented in the Philippines by a single species, E. cu- 
neatum (Wall.) Kurz (E. burmanicum Griff.), extending from British India 
to the Malayan Peninsula, Sumatra, Java, and Luzon.
