the glumes unequal, lanceolate, blunt, one 4 mm. long, one 5 mm. long. 
Flowers 4, hermaphrodite, each with one hyaline oblong-obovate acute 
bract about 4 mm. long. Stamen 1; filament 3 mm. long; anther 
oblong, 1-celled, 1.5 mm. long. Ovary 2-celled, the ovules superposed; 
styles two, 2 to 2.5 mm. long. 
In open heaths at 2,400 m. alt. (No. 6160). 
Perhaps the most interesting discovery in recent botanical exploration of the 
Philippines, the family and genus being new to the Philippine flora, both being 
largely developed in Australia and New Zealand. Of the six genera at present 
recognized in the family, four, Juncella, Brizula, Aphelia, and Alepyrum are con- 
fined to Australia, New Zealand and Tasmania, a fifth genus of two species, 
Gaimardia, is represented in New Zealand, Cape Horn and the Falkland Islands, 
while the sixth genus, ' Centrolepis, is represented by about twenty species, of 
which one is found in Cambodia, and all the others, except the one described 
here, in south Australia and Tasmania. Following Hieronymus’ treatment of 
the family in Engler und Prantl’s Natiirliehen Pfianzenfamilien, the present 
species would perhaps fall in the genus Alepyrum, but as Alepyrum Hiern., is 
invalidated by Alepyrum R. Br., it has been thought best to describe the present 
species under Centrolepis. 
EKIOCAULONACE.E. 
ERIOCAULON Linn. 
Eriocaulon brevipedunculatum Merrill, n. sp. 
Planta densissime caespitosa, 5 ad 8 cm. a\ta, caulibus brevissimis, 
simplicibus, foliis congestis, anguste lanceolatis, acuminatis, 2 ad 2.5 cm. 
longis, 3 ad 4 mm. latis, glabris, pedunculis perbrevibus 0.5 ad 1 cm. 
longis; capitula semiglobosa, 5 ad 6 mm. lata, bracteis involucrantibus 
latiusculis, membranaceis, obtusis, ad 3 mm. longis ; ■ flores normaliter 
evoluti; perigonia 3-mera. 
Densely csespitose, 5 to 8 cm. tall, forming dense tufts. Stems short, 
simple; leaves very numerous, densely disposed throughout the entire 
length of the stem, the lower ‘ ones marcescent, narrowly lanceolate, 
acuminate, glabrous, 2 to 2.5 cm. long, 3 to 4 mm. wide, spreading, 
shining, flaccid. Peduncles solitary, the peduncles 0.5 to 1 cm. long, 
longis; capitula semiglobosa, 5 ad 6 mm. lata, bracteis involucrantibus 
mambranaceous, obtuse, about 3 mm. long, obovate. Staminate flowers 
3-merous; sepals free, spatulate, slightly ciliate at the apex, about 2.5 
mm. long; petals narrowly ovate, acuminate, 1 mm. long, the gland 
prominent; stamens 6, the filaments about 1 mm. long. Pistillate 
flowers 3-merous ; sepals free, narrowly oblong or spatulate, obtuse, 
slightly ciliate above, about 2.5 mm. long; petals equaling the sepals, 
somewhat narrower; style about 1.5 mm. long, the three style-arms 
nearly 2 mm. long. 
In an open heath at 2,400 m. alt. (No. 6214). 
A species well characterized by its densely csespitose habit and short peduncles, 
the heads being solitary and included in the densely disposed leaves, not exserted.
