248 ‘ MERRILL. 
Prain, D. Report on the Indian Species of Pterocarpus. (Stray Leaves from 
Indian Forests j issued with Indian Forester 26 (1900) No. 10, pp. 1-16.) 
Five species are considered, especially with a view to the identity of the 
species yielding the padouk timber of commerce. But one species considered 
extends to the Philippines, P. indicus Willd., but in a footnote on page 10, 
the Philippine P. vidalianus Rolfe is reduced to P. echinatus Pers., a species 
previously known only from south Celebes. 
Rendle, A. B. Najadaeeae. (Das Pfianzenreich 7 (1901) pp. 1-21.) 
A single genus, Najas Linn., is recognized, containing 32 species and many 
varieties, of which the following are found in the Philippines: Najas 
foveolata A. Br., N. falciculata A. Br., and N. graminea Del. 
Robinson, C. B. The History of Botany in the Philippine Islands. (Journ. N. Y. 
Bot. Gard. 7 (1906) pp. 104-112.) 
A sketch of the history of Philippine botany from the year 1587 to the 
year 1906, including some data not included by Merrill in his “Botanical 
Work in the Philippines.” 
Robinson, C. B. Some Affinities of the Philippine Flora. (Torreya, 7 (1907) 
pp. 1-4.) 
A review of the introduction to Merrill’s “New or Noteworthy Philippine 
Plants, V” Philip. Journ. Sci. 1 (1906) Suppl. pp. 169-246. 
Ruhland, W. Eriocaulonaceae. (Das Pfianzenreich, 13 (1903) pp. 1-294.) 
Nine genera are recognized of which but one, Eriocaulon Linn., with 193 
species, is represented in the Philippines. The species credited to the Phil- 
ippines are E. truncatum Ham., which should be excluded as the specimen 
cited from the Philippines, No. 2326 Cuming, was not collected in the Archi- 
pelago but in Malacca; E. sexangulare Linn., British India to China and the 
Philippines, and E. sieholdianum Sieb. et. Zucc., British India to China, Japan, 
the Philippines and Java. One species has been described from Philippine 
material since the publication of the above monograph, E. merrillii Ruhl. 
Schindler, Anton K. Halorrhagaceae. (Das Pfianzenreich. 23 (1905) pp. 1-133.) 
Of this family but a single species, Gunnera macrophylla Blume, Java, 
Sumatra, Luzon and New Guinea, is credited to the Philippines. Since the 
publication of the monograph however the following species have been added 
to the Philippine flora: Myriophyllum spicatum L., widely distributed; 
Halorrhagis micrantha (Thunb. ) R. Br., H. philippi/nensis Merr., H. scabra 
var. elongata Schindl., and H. halconensis Merr. 
Schumann, K. Musaeeae. (Das Pfianzenreich, 1 (1900) pp. 1-45.) 
Five genera are recognized, two being represented in the Philippines, one 
Musa by many forms, the other Ravenala by occasional cultivated specimens. 
The only species of Musa credited to the Philippines by Schumann are M. 
textilis N6e, the source of abaca, Manila hemp, and forms of M. paradisiaca 
L., the common banana and plantain. No attempt is made to reduce the 
numerous forms described by Blanco in his “Flora de Filipinas.” Ravenala 
madagascarensis Sonn., the “traveller’s palm” has been introduced into the 
Archipelago and is occasionally cultivated for ornamental purposes. 
Schumann, K. Zingiberaceae. (Das Pfianzenreich, 20 (1904) pp. 1-458.) 
The following species are credited to the Philippines: Hedychium philip- 
pinense K. Schum., endemic; (Brachychilus a genus of two species apparently 
erroneously credited to the Philippines in note on generic distribution and 
in conspectus of species, but under the species the Philippines are not 
mentioned) ; Globba brevifolia K. Schum., G. gracilis K. Schum., G. camp- 
sophylla K. Schum., G. parviflora Presl, G. pyramidata Gagnepain, G.
