THE FLOIEA OF MOUNT HALCON. 265 
tile glumes imequal, lanceolate, blunt, one 4 mm. long, one 5 mm. long. 
Flowers 4, lierniaplirodite, each with one hyaline oblong-obovate acute 
bract about 4 mm. long. Stamen 1; filament 3 mm. long; anther 
oblong, 1-cclled, 1.5 mm. long. Ovary 2-celled, the ovules superposed; 
styles two, 2 to 2.5 mm. long. 
In open heaths at 2,400 ni. alt. (No. 6100). 
Perhaps the most interesting diseovery in recent boianicul cxiiloration of tlio 
Philippines, the family and genus being new to the Philippine flora, both being 
lar^^uly developed in Australia and Nbav Zealand. Of the six genera at present 
recognized in the family, four, Juncella, BHzula, Aphelia, and Alcpyrnm are con- 
fined to Australia, New Zealand and Tasmania, a fifth genus of two species, 
(iaimardia, 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 TFirronymufi' treatment of 
the family in Engl^r und PrantVs Natiirliclu'n Ptlanzenfamilien, the present 
species would perhaps fall in the genus Alepyrum, but as Alcpyrum Hiern., is 
invalidated by Alepyrum R. Br., it has been thought best to describe the present 
species under Genirolepis.

latiusculis, membranaceis, obtusis, ad 3 mm. longis; flores normalite.r 
evoluti; perigonia .3-mera. 
Densely caespitose, 5 to 8 cm. tall, forming dense tufts. Stems short, 
simple; leaves very numerous, densely disposed tliroughout 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 solitar}-, the peduncles 0.5 to 1 cm. long. 
longis; eapitula 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 T 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 aboiit 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 cffspitosc habit and slmrt peduncles, 
the heads being solitary and included in the densely disjiosed leaves, not exscrted.
