BOERLAGIODENDRON ftarms 

 BOERLAGIODENDRON YATESII sp. nov. 



Frutex glaber ; f oliis palmatim 5- ad 7-f oliolatis, f oliolis coria- 

 ceis, oblongls ad oblongo-ellipticis, 8 ad 18 cm longis, omnibus 

 petiolulatis, acuminatis, basi acutis, margine irregulariter serra- 

 tis, dentibus mucronatis; infldrescentiis 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. 254.18 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.

 gine distanter denticulatis ; petiolis circiter 30 cm longis in di- 

 midio inferiore cristis obliquis pectinatis distantibus instructis; 

 inflorescentiis circiter 6 cm longis, furfuraceis, radiis primariis 

 circiter 15, tenuibus; fructibus sessilibus, ovoideis, 3-sulcatis,
