364 MERRILL AND MERRITT. 
GUTTIFERZ. 
HYPERICUM Linn. 
1. H. japonicum Thunb. Fl. Jap. (1784) 295, pl. 31; Lév. in Bull. Soc. Bot. 
France IV 7 (1908) 591. 
Habitat not given, probably in the upper pine region, McGregor 8884. 
Common in the Benguet-Lepanto region, and occasional at medium and higher 
altitudes southward; Japan to eastern India southward to Australia and New 
Zealand. 
2. Hypericum pulogense Merrill sp. nov. 
Herba suffruticosa, erecta, glabra, 20 ad 40 cm alta; foliis sessilibus, 
ellipticis vel oblongo-ellipticis, 1 ad 2 cm longis, obtusis, subtus subglau- 
cescentibus, glandulosis; floribus 2.5 ad 3 cm diametro; capsulis trilocel- 
latis; styli 3. 
An erect, glabrous, suffrutescent herb 20 to 40 em high. Stems 
slender, terete, firm, reddish or yellowish, smooth, 1 to 1.5 mm in 
diameter, with two longitudinal lines along the internodes between each 
two pairs of leaves. Leaves chartaceous to subcoriaceous, elliptic to 
oblong-elliptic, 1 to 2 cm long, 3.5 to 7 cm wide, obtuse, sometimes 
slightly retuse, sessile but not connate, slightly glaucous and strongly 
glandular beneath; nerves slender, ascending, obscurely anastomosing. 
Flowers yellow, solitary in the upper axils, or in 3-flowered corymbs, 2.5 
to 3 cm in diameter. Sepals oblong or elliptic-oblong, 6.5 mm long, 2.2 
to 2.7 mm wide, glabrous, obtuse, coriaceous, the upper half distinctly 
glandular. Petals narrowly oblong-obovate, inequilateral, 14 mm long, 
5 to 6 mm wide, sparingly punctate-glandular on the upper half and near 
the borders, rounded. Stamens in five phalanges. Ovary narrowly ovoid, 
4°’mm long, 3-celled; styles 3, free throughout, 5 mm long. Capsule 5 
to 6 mm long, narrowly oblong-ovoid, 3-celled; seeds oblong-elliptic, 1 
mm long. ; 
Abundant in the open grass lands of the summit, and also in open places in 
the mossy forest, O. M. Z. 16097, Merrill 6577, McGregor 8875, 8880. 
The third species of the genus to be found in the Philippines, and apparently 
most closely allied to Hypericum perforatum Linn., which extends from. Europe 
and northern Africa to northwestern India and northern and central China, intro- 
duced in North America. 
VIOLACEZ. 
VIOLA Linn. 
1. V. toppingii Elm, Leafl. Philip. Bot. 2 (1908) 505. 
In the mossy forest, C. M. Z. 16063bis, 16219, Merrill 6503, and in ravines 
_ in the summit grass lands, Merrill 6493. 
Widely distributed at high altitudes in the Benguet-Lepanto region, and rather 
variable. As Viola serpens Wall. is construed in Hooker’s “Flora of British In- 
dia,” it seems to me that it would include this Philippine form. V. toppingii is 
represented also by the following specimens: District of Lepanto, Mount Data, 
Merrill 4509, 4565: Province of Benguet, Pauai, Merrill 4769, Bur. Sci. 4363, 
4388 Mearns; Baguio, Topping 119, Elmer 6042.
