17. 3 Merrill: Noteworthy Philippine Plants, XVI 251 



BUCAS Grande, Bur. Sci. 35068 Ramos & Pascasio, June 10, 

 1919, in dry forests at low altitudes. 



This species is probably more closely allied to Oxymitra paw- 

 cinervia Merr. than to any other species, but differs in its fewer- 

 nerved leaves which are not at all glaucous beneath. 



GONIOTHALAMUS Hooker f. and Thomson 

 GONIOTHALAMUS PANAYENSIS sp. nov. 



Arbor parva, ramulis junioribus et floribus plus minusve pu- 

 bescens; foliis chartaceis vel subcoriaceis, oblongis, 15 ad 30 cm 

 longis, basi acutis, apice tenuiter acuminatis, nervis utrinque 

 circiter 12, perspicuis; floribus solitariis vel fasciculatis e trun- 

 cis vel ramis majoribus, breviter pedicellatis, circiter 2.5 cm 

 longis; petalis exterioribus lanceolatis, crasse coriaceis sursum 

 angustatis, utrinque plus minusve pubescens; petalis interiori- 

 bus circiter 1.3 cm longis, conniventibus. 



A tree, about 5 m high, the very young branchlets sparingly 

 pubescent, the flowers usually densely so, otherwise glabrous. 

 Leaves chartaceous or subcoriaceous, oblong, shining, 15 to 30 

 cm long, 4 to 10 cm wide, the base acute, apex slenderly acu- 

 minate; lateral nerves about 12 on each side of the midrib, 

 prominent, the reticulations rather lax, distinct; petioles 1 to 

 2 cm long. Flowers yellowish, solitary or fascicled on the trunk 

 and larger branches, rarely axillary on the younger branches, 

 their pedicels densely pubescent, about 4 mm long, usually sub- 

 tended by a pair of small bracts. Calyx about 1.3 cm in diam- 

 eter, the lobes ovate, acute or somewhat acuminate, more or 

 less pubescent. Outer 3 petals lanceolate, apparently fleshy, 

 thickly coriaceous when dry, about 2.5 cm long and 8 mm wide, 

 narrowed upward to the acute or slightly acuminate apex, 

 slightly constricted toward the base, both surfaces more or less 

 pubescent with short, appressed, shining, brownish hairs. In- 

 ner petals about 1.3 cm long, appressed-pubescent, connivent.

 in forests. 



This species is distinctly allied to Goniothalamus amuyon 

 (Blanco) Merr., from which it is readily distinguished by its 

 larger, slenderly acuminate leaves, and smaller flowers.
