Luzon, Bontoc Subprovince, Lessep, Father M. Vanoverhergh 590, June, 
1910, in still water, altitude 1,100 m. 
A specimen from Benguet Subprovince, collected by Major E. A. Mearns, 
But, Sci. 2825, probably also belongs to this species, but may possibly be a 
very small form of Chara corallina. Being old and without fruit, it cannot 
be determined with certainty. Chara Braunii is almost world-wide in its 
distribution, occurring in all the continents. The specimen from Bontoc 
may be characterized as /. meiocarpa microptila unilateralism 
5. Chara Benthami Braun in Monatsb. Berl. Akad. (1867) 799. 
A specimen from stagnant fresh water from near sea-level, Bucas Island, 
a small island northeast of Mindanao, Merrill 5265, October, 1906, is, we 
think, best referred to this species. Braun separated Chara Benthami from 
C. gymnopitys, to which it is closely allied, by its having one stipulode to 
each branchlet instead of two as in the latter species, but in the original 
specimen from Hongkong in the Kew Herbarium, this character is not 
constant. 
6. Chara gymnopitys Braun in Linnaea 25 (1852) 708. 
SiBUYAN, Magallanes, Elmer 12382, April, 1910. 
This species has been found in Socotra, India, Ceylon, Straits Settlements, 
Tonkin, China, New Guinea, Australia, New Zealand, and Tasmania, also 
in the United States of America. 
The plant from the Philippines may be characterized as /. tylacantha 
macracantha meiocarpa. 
7. C. flaccida Braun in Hook. Journ. Bot. 1 (1849) 296. 
Luzon, Manila, in shallow pools (about 20 cm), W. R, Shaw 1173, 
February, 1912. 
In describing Chara flaccida, Braun separated it from C Hydropitys 
by the yellow oospores and the always uncoated branchlets. C. gymnopitys 
was subsequently described with black or nearly black oospores, but it is 
so very similar in other respects to C. flaccida that we think a more 
extended knowledge of its various forms may prove that it should be 
regarded as a subspecies. 
8. Chara brachypus Braun in Hook. Journ. Bot. 1 (1849) 298. 
Luzon, Province of Rizal, in rather swift water of the Maraquina River, 
near the Manila waterworks dam at the Montalban Gorge, Merrill 5098, 
March, 1906. 
A fairly typical form of this rare species which occurs in India and New 
Guinea, also in Africa and in Australia. 
9. Chara zeylanica Willd. in Mem. Acad. Berol. 1803 (1805) 86, t. II, A I- 
C, gymnopus Braun, sens, lat, 
Luzon, Province of Rizal, Maricaban, near Manila, Merrill 7^62, Feb- 
ruary, 1911, in shallow muddy pools of fresh water at sea level; Pasay, 
Merrill 7586, April, 1911, in stagnant pools of fresh water at sea level. 
The commonest of the tropical species of Characeae, occurring in India, 
Ceylon, Burma, and Java, as well as in Africa, North and South America, 
and Australia. The plants from Luzon come under Braun's variety 
ceylonica.
