MINDORO, Paluan, Bur. Sci. 39639 Ramos, April 13, 1921. On 
forested slopes, altitude about 550 meters. 
In aspect this species rather closely resembles a small-leafed 
form of Guioa koelreuteria (Blanco) Merr. (G. perrottetii 
Radlk.). Its distinguishing characters are its small leaflets and 
the narrowly winged or carinate upper portions of the leaf 
rachises. In the latter character it somewhat approaches Guioa 
pleuropteris*Radlk., but is remote from that species in all other 
characters. 
RHAMNACEAE 
RHAMNUS Tournefort 
RHAMNUS MOLLIS sp. nov. 
Frutex scandens, molliter pubescens; foliis subcoriaceis, el- 
lipticis, 10 ad 13 cm longis, breviter acuminatis, basi rotunda- 
tis, margine minute crenato-dentatis, nervis utrinque 6, perspi- 
cuis; infructescentiis paniculatis, circiter 12 cm longis, ramis 
racemose dispositis, 5 ad 10 cm longis; fructibus pedicellatis, 
obovoideis, glabris, circiter 8 mm longis, calycis persistentibus, 
truncatis, disciformibus, pubescentibus, 2 mm diametro. 
A scandent shrub, the younger parts, leaves, and inflorescences 
softly subferruginous-pubescent, branches terete, about 3 mm 
in diameter. Leaves subcoriaceous, elliptic, 10 to 18 cm long, 
6 to 7.5 cm wide, olivaceous, shortly acuminate, base usually 
rounded, the margins rather minutely crenate-dentate, the lower 
surface densely and softly pubescent with short hairs; lateral 
nerves 6 on each side of the midrib, prominent; petioles more 
or less pubescent, about 1.5 cm long. Fruits racemosely ar- 
ranged on leafless branches forming a paniculate infructescence 
about 12 cm long, this infructescence sometimes supplied with a 
few very greatly reduced leaves, the branches 5 to 10 cm long. 
Fruits solitary or in pairs, obovoid, glabrous, brown when dry, 
about 8 mm long, the persistent calyx disklike, truncate, pu- 
bescent, about 2 mm in diameter. 
LUZON, Bontoec Subprovince, Mount Polis, Bur. Sci. 37689 
Ramos & Edafio, February 25, 1920. In the mossy forest, al- 
titude about 1,600 meters. 
Among the Philippine species the present one is manifestly 
allied to Rhamnus philippinensis C. B. Rob., from which it is 
at once distinguishable by its indumentum; among the extra- 
Philippine species it is apparently closest to R. triqueter Wall. 
of India.
