Luzon, Province of Rizal, Masambong, along small streams on ledges 
subject to overflow in high water, Merrill 7396, December, 1910 (type), 
Phil. PI. 755 Merrill, January, 1911. 
A rather characteristic species, quite different from the few other forms 
of the genus at present known from the Philippines. 
STYLIDIACEAE. 
In Milbraed’s recent monograph of the family^® six genera and one 
hundred and twenty species are recognized, with the following range: 
Donatia with two species, one in Antarctic South America to Chile and 
one in New Zealand and Tasmania; Phyllachne with four species, one 
in Antarctic South America and three in New Zealand; Forsteria with 
four species in New Zealand and Tasmania; Oreostylidium with a single 
species in New Zealand; Levenhookia with 6 species in Australia, chiefly 
in the western part; and Stylidium with 103 species, nearly all confined 
to Australia, a few extending to Tasmania, and three extra-Australian 
species. These three belong in the section Andersonia, which has twelve 
species, of which nine are confined to Australia, one, S. uliginosum Sw., 
Australia (Queensland), southern China, and Ceylon, and two do not 
occur in Australia, S. tenellum Sw., India to Tonkin and Malacca, and 
S. kunthii Wall., confined to India. For some years a species has been 
known from the Philippines, but its occurrence here has not before defi- 
nitely been published. This species is of special interest as it adds another 
distinct Australian type to our knowledge of the Philippine flora, S. 
alsinoides R. Br., previously known only from Australia, forming with 
iS. tenerrhnum F. MuelL, the section Alsinoides.

The determination of the Philippine material was, I believe, first made 
by Mr. Rolfe, but one specimen that I sent to Kew was so determined 
by Mr. Hemsley. Later I examined the material in the Kew herbarium 
and came to the conclusion that the determination was correct. Still more 
recently, through the kindness of Mr. F. Manson Bailey, of Brisbane, 
Dr. A. J. Ewart of Melbourne, and Mr. J. H. Maiden of Sydney, I have 
received a fine series of Australian specimens of Stylidium alsinoides R. 
Br., and also representative material, including a fragment of the type, 
of S. tenerrimum F. Muell. This material enables me to make a direct 
Pflanzenreich 35 (1908) 1-98.
