By Elmer D. Merrill. 
(From the botanical section of the Biological Laboratory, Bureau of Science.) 
Anonymous. Decades Kewensis, Decas XLII. (Kew Bull. (1906) pp. 200-205.) 
One Philippine species. Peracarpa luzonica Rolfe, is described on page 201, 
from Northern Luzon, the only other known species of the genus, P. carnosa 
Hook. f. et Th., extending from Northern India to Yunnan. 
Boorsma, W. G. Ueber philippinisehe Pfeilgifte. (Bull. Vlnst. Bot. Buitenzorg 
6 (1900) pp. 14-18.) 
A consideration of Lunasia amara Blanco and Lophopetalum toxicum Loher, 
in connection with the use of the bark as a source of arrow poison. 
Ceron, S. Catalogo de las plantas del herbario recolectado por el personal de la 
suprimida eomision de la flora forestal. (Manila (1892), pp. 1-231, plate 1.) 
A catalogue of a portion of the plants collected in the Philippines by Vidal, 
including those enumerated by the latter in his Revision de plantas vasculares 
Filipinas (1886), and some collected after the publication of that work. A 
number of genera and species are credited to the Philippines for the first time 
and one new species is described, Calophyllum vidalii F.-Villar, 1. c. 229, 
with plate, G. cuneatum Vidal and G. rolfei Vidal being cited as synonyms. 
It is not entirely clear who is the author of the entire work, but Ceron’s 
name, then “Inspector general de Montes” for the Philippines appears on page 
5 at the end of the introduction. The enumeration of species is however 
apparently the work of Regino Garcia.

culty des sciences de Paris (1901) pp. 1-257, plates 9, reprint from Mem.

Three genera, Ga,le, Gomptonia and Myrica are recognized, the latter con- 
taining 51 species and many varieties, represented in the Philippines by the 
endemic Myrica vidaliana Rolfe. Other species of the genus have since been 
found in the archipelago.

Securidaca philippinensis is described as new.

from Philippine material, the first two endemic, the last extending from the 
Philippines to Borneo and Malaca.
