ut costa leviter, subtus magis elevatis, reticulo nervulorum 
subtus praecipue in foliis dentatis conspicue elevato, supra minus 
vel interdum saltem in foliis integris vix elevato; petioli validi, 
5-7 mm. longi, glabri. Flores cremeo-albidi, fragrantes, fas- 
ciculati, e gemmis axillaribus; pedicelli graciles, circiter I cm. 
longi ; lg brevissimus irregulariter vel interdum indistincte 
4-lobatus lobis latioribus quam longis eroso-denticulatis vel integ- 
ris; corolla circiter 5 mm. longa, fere ad basin 4-partita lobis el- 
lipticis; stamina paullo supra basin inserta corolla paullo

Cuina : Northwestern Yunnan; mountains west of Yungspels, 
Lat. 26° 30’ N., Long. 100° 50’ E., altitude 8—gooo ft., amongst 
scrub on open rocky hillsides and in open mixed forests. G. 
Forrest, No. 21,050 (spinous-leaved shrub of 9-20 ft.; flowers 
sweetly fragrant, creamy white). 
This new species seems most closely related to O. armatus, 
Diels and O. serrulatus, Rehder; the former is easily dis- 
tinguished by the minute pubescence of the winter-buds, young 
branchlets and petioles, by the comparatively narrower leaves not 
reticulate beneath and with fewer and broader spiny teeth, and by 
the less deeply divided corolla; O. serrulatus differs chiefly in its 
cuneate leaves usually broadest above the middle, not reticulate 
beneath and with smaller and more numerous teeth pointing for- 
ward, in the slenderer and longer petioles and pedicels, in the 
‘Linger calyx and in the narrower anthers on longer he ati
