13. Begonia loheri sp. nov. 
Erecta, parce ramosa, ramulis, petiolis, subtus foliisque ad nervos 
brunneo-setosis ; foliis oblongis, inaequilaferalibus, basin versus admodum 
angustatis, subsessilibus vel breviter petiolatis, 2 ad 5 cm longis, apice 
acuminatis, basi oblique leviter subcordatis, margine irregulariter lobatis 
et setoso-dentieulatis ; inflorescentiis in axillis* superioribus, 1.5 ad 4 cm 
longis, angustis, paucifloris, parce ciliatis, bracteis prominentibus instruc- 
tis ; floribus masculinis sepalis 2, suborbicularibus, circiter 7 mm longis, 
basi cordatis; capsulis circiter 1 cm longis, ut videtur aequaliter 3-alatis. 
An erect, somewhat branched plant about 20 cm high, the lower parts 
of the stems often prostrate and rooting, the branches, petioles, and 
leaves on the nerves on the lower surface distinctly brown-setose. Leaves 
oblong, 2 to 5 cm long, 0.7 to 2 cm wide, somewhat narrowed towards 
the inequilaterally and slightly cordate base, apex acuminate, margins 
irregularly lobed towards the apex, otherwise dentate and setose-denti- 
culate; basal nerves about 6, the outer ones very short, those above the 
basal ones about 4 on each side of the midrib; petioles 3 mm long or 
less, densely brown-setose; stipules cili'ate, obliquely oblong-ovate, ac- 
uminate, about 8 mm long. Panicles in the uppermost axils, solitary, 
narrow, few-flowered, slightly ciliate; bracts oblong-ovate, acuminate, 
membranaceous, about 6 mm long. Male flowers apparently pink. Sepals 
suborbicular, rounded, base cordate, about 7 mm long. Petals none. 
Stamens about 18. Capsules (every old) about 1 cm long, apparently 
truncate and equally 3-winged.

14. Begonia jagori Warb. in Perk. Frag. FI. Philip. (1904) 54. 
Luzon, without definite locality, Jagor 889, 890, in herb. Berol. Mindoro, 
Mount Halcon, Merrill 5685 (formerly reported as B. incisa, A. DO.) ; Ibalo 
River, For. Bur. 1201/9 Merritt ; Baco River, Merrill 11/8 1/ ; south of Lake Naujan, 
For. Bur. 672/6 Merritt; without definite locality, For. Bur. 8712 Merritt. Endemic. 
Dr. I. Urban, of the Berlin Herbarium, has kindly supplied the herbarium 
of the Bureau of Science with a duplicate specimen of one of Jagor’s numbers. 
Begonia Jagori Warb. is apparently closely allied to B. incisa A. DC., but the 
typical form is distinguished by its only toothed, not lobed leaves. The Mindoro 
material cited above has rather deeply lobed leaves, and some forms rather 
closely approach Begonia incisa A. DC. 
Endemic.

of Zambales, Bur. Sci. 1/993 p. p. Ramos: Province of Sorsogon, specimen ex 
herb. Bonpland in the Berlin Herbarium, probably cotype. Negros, G-imagaan 
River, Whitford 1582, For. Bur. 1/253 Everett, March, May, 1906. 
A most characteristic endemic species, well characterized by its deeply incised 
leaves. The type is in the Boissier Hermarium, the collector and the definite 
locality, other than “Philippines,” not being given; A. De Candolle surmises Nee
