BOER LAG I ODEN DRON Harms 
BOERLAGIODEN DRON YATESII sp. nov. 
Frutex glaber ; foliis palmatim 5- ad 7-foliolatis, foliolis coria- 
ceis, oblongis ad oblongo-ellipticis, 8 ad 18 cm longis, omnibus 
petiolulatis, acuminatis, basi acutis, margine irregulariter serra- 
tis, dentibus mucronatis; inflorescentiis terminalibus, subses- 
silibus, umbellatis, radiis primariis 5 vel 7, usque ad 3 cm longis, 
dichotomis vel trichotomis ; floribus in capitulis globosis subcon- 
fertis, 4-meris, capitulis circiter 1 cm diametro. 
An erect glabrous shrub, the branches terete, brownish, 8 to 
10 mm in diameter. Leaves alternate, palmately 5- to 7-foliolate, 
their petioles 13 to 20 cm long, the basal crests 2 or 3, coriaceous, 
glabrous, not at all pectinate; leaflets coriaceous, oblong to 
oblong-elliptic, 8 to 18 cm long, 4.5 to 7 cm wide, apex rather 
prominently acuminate, base acute, in the outer leaflets inequila- 
teral, margins very irregularly serrate, the teeth minute to 
rather coarse or even slightly sinuate, mucronate ; lateral nerves 
6 to 10 on each side of the midrib, distinct; petiolules 0.5 to 
2.5 cm long. Inflorescence terminal, umbellate, subsessile, the 
primary branches 5 to 7, usually about 3 cm long, these trichoto- 
mous or dichotomous, the secondary lateral branches '2 to 2.5 
cm long, the central branch very short and bearing a head of 
sterile flowers. Heads at the tips of the lateral branches globose, 
about 1 cm in diameter, each composed of from 10 to 15 pedicelled 
flowers, the pedicels in young fruit 2 to 3 mm long, the subtend- 
ing bracteoles elliptic-ovate, rounded, about 3 mm long, their 
margins ciliate. Very young fruits subellipsoid, about 4 mm 
long, with 4 obscure, rounded angles. 
Luzon, Tayabas Province, Mount Cadig, Bur. Sci. 25^18 Yates, December 
12, 1916, in the mossy forest near the summit of the mountain. 
A very characteristic species, readily distinguished by its palmately 5- 
to 7-foliolate leaves, and its comparatively small, coriaceous leaflets. It is 
perhaps most closely allied to Boerlagiodendron heterophyllum Merr.
