20,4 Merrill: Noteworthy Philippine Plants, XVII 405 



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 Toumefort 

 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 mjn 

 in diameter. Leaves subcoriaceous, elliptic, 10 to 13 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, Bontoc Subprovince, Mount Polls, Bur. Sci. 37689 

 Ramos & Edano, February 25, 1920. In the mossy forest, al- 

 titude about 1,600 meters. 



Among the Philippine species the present one is manifestly 

 allied to Rhamnv^ 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.
