Christ, H. Die Farnflora von Celebes. (Ann. Jard. Bot. Buitenz. 15 (1897) pp. 
73-186, plates 5.) 
An enumeration of the ferns known from Celebes, 308 species being listed, 
with numerous references to species growing in the Philippines. 
Copeland, Edwin Bingham. Outline of a Year’s Course in Botany. (Bureau of 
Education ( Manila ) Bull. 24 (1906) pp, 1-18.) 
An outline of the work in botany given at the Philippine Normal School, 
Manila, and in the secondary schools of the Archipelago. 
Copeland, Edwin Bingham. Key to the Families of Vascular Plants in the 
Philippine Islands. (Bureau of Education ( Manila ) Bull. 24 (1906) pp. 
19-32.) 
An analytical key to the families of vascular plants known to be 
represented in the Philippines, following the system of Engler and Prantl, 
followed by a systematic enumeration of the families, 199 families being 
listed. 
Copeland, Edwin Bingham. Fungi esculentes Philippinenses. (Ann. Mycol. 
(1905) 3: pp. 25-29.) 
Twenty-one species described in the following genera: Lycoperdon, Gopri- 
nus, Panaeolus, Agaricus and Lepiota. In Govt. Lab. Publ. 28 (1905) pp. 
141-146, the above paper is reprinted in English, with the addition of three 
half-tone plates under the title “New Species of Edible Philippine Fungi.” 
Diels, L. Droseraceae. (Das Pflanzenreich 26 (1906 pp. 1-136.) 
A single genus, Drosera, is represented in the Philippines by the following 
species: D. indica L., British India to Australia, D. spathulata Labill., 
southern Japan and China to East Australia and New Zealand, and D. peltata 
Smith, British India to Australia. 
Engler, A. Araceae-Pothoideae. (Das Pflanzenreich 21 (1905) pp. 1-330.) 
The following species are credited to the Philippines: Pothos longifolius 
Presl, Philippines to Java, Sumatra and the Moluccas; P. scandens Linn., 
British India to Malaya; P. inaequilaterus (Presl) Engl., Philippines and 
Sumatra; P. ovatifolius Engl., endemic; P. philippinensis Engl., endemic; 
P. luzonensis (Presl) Schott, endemic; Pothoidium lobbianum Schott, a 
monotypic genus, Philippines, Celebes and the Moluccas. No form of Acorus 
is credited to the Archipelago, but the genus is represented in Luzon by 
forms referred to A. calamus L., but of which I have seen only sterile 
specimens. The Philippine form is possibly referable to A. gramineus Soland.
