THE FLORA OF MOUNT HALCON. 
301 
long, 0.5 to 1.5 cm. wide, the base inequilateral, acute, the apex acute or 
somewhat acuminate, the tip blunt, the margins slightly repand-crenate 
or subentire, submembranous, glabrous above, paler and somewhat ferru- 
ginous-hirsute on the midrib beneath or quite glabrous; nerves 4 to 5 
on each side of the midrib ; petioles 1 cm. long or less, ferruginous- 
hirsute. Flowers axillary, solitary, long-pedicelled, about 1.5 cm. long, 
the pedicels sparingly hirsute, 1 to 2 cm. long, slender, bibracteolate at 
about the middle, the bracts narrow, 2 mm. long or less. Calyx glabrous 
or nearly so, the tube broad, about 3 mm. long, the teeth about 4 mm. 
long, broadened at the base, narrowed abruptly and linear-lanceolate 
above, persistent and slightly accrescent in fruit. Corolla about 1.5 cm. 
long, glabrous, the lobes narrowly-ovate, obtuse, 5 to 6 mm. long. 
Samens 2; anthers broad, about 1.2 mm. long. Style slightly hirsute. 
Fruits ovoid, fleshy, dark purple, glabrous, about 5 mm. long. 
In forests at 1,800 m. alt. (Nos. 5718, 5777). The same species, but witli 
shorter petioles and somewhat narrower leaves has been collected on Mount Ma- 
lindang, Mindanao, at an altitude of 1,700 m. (No. 4753 Mearns and Hutchinson) 
May, 1906. A sterile specimen from Canlaon Volcano, Negros, collected by Banks 
in March, 1902, with more strongly sinuate leaves is probably referable here. 
Cyrtandra sp. 
In forests at 900 m. alt. (No. 4350 Merritt) June, 1906. 
A characteristic, apparently undescribed species, with very long petioles, but 
the material rather imperfect. 
Cyrtandra sp. 
In forests at 1,400 m. alt. (No. 5770), an undershrub 1 to 1.5 m. high. 
LENTIBULAKIACEJE. 
UTRICULARIA Linn. 
Utricularia orbiculata Wall. Cat. (1828) No. 1500. 
On seepy slopes, open heath at 2,400 m. alt. (No. 6168) ; flowers pale purple. 
Not previously reported from the Philippines. 
Southeastern Asia, through the Malayan Peninsula to Mount Kinabalu, North 
Borneo. 
Utricularia sp. 
On rocks along the Alag River at 150 m. alt. (No. 5547). Possibly referable 
to the preceding, but the material very imperfect. 
ACANTHACEJE. 
JUSTICIA Linn. 
Justicia luzonensis C. B. Clarke in Govt. Lab. Publ. 35 (1905) 91. 
In damp shaded ravines along the Alag River at 150 m. alt. (No. 5622). 
Previously collected on the Baco River, near the base of Mount Halcon by Merrill 
(No. 1778), April, 1903, and by McGregor (No. 156) March, 1905. 
Known only from Luzon and Mindoro.
