13. Begonia loheri sp. nov. 
Erecta parce ramosa, ramulis, petiolis, subtus foliisque ad nervos 
brunneo-setosis ; foliis oblongis, inaequilateralibus, ba^in versus admodum 
angustatis, subsessilibus vel breviter petiolatis, 2 ad 5 cm longis, apice 
acuminatis, basi oblique leviter subcordatis, margine irregulanter lobatis 
et setoso-denticulatis ; inflorescentiis in axillis superioribus, 1.5 ad 4 cm 
longis, angustis, paucifloris, parce ciliatis, bracteis prominentibus mstruc- 
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 incquilatei-ally 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 cilia te, obliquely oblong-ovatc, 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 
suborbicnlar, 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.

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. 
Beijonia Jagori Warb. is apparently closely allied to B. ineisa A. DC, but the 
typical form is distinguished by its only toothed, not lobed leaves. Tlie Mindoro 
material cited above has rather deeply lobed leaves, and some forms rather 
closely approach Brqonia incisa A. DC 
Endemic.
