RYPAROSA Blume 

 RYPAROSA ACUMINATA sp. nov. 



Arbor, ramulis adpresse hirsutis, inflorescentiis s elongatis, 

 dense adpresse ferrugineo-hirsutis ; foliis oblongis, subcoriaceis, 

 tenuiter acute acuminatis, usque ad 22 cm longis, basi acutis, 

 subtus pallidis, nervis utrinque 3 vel 4, curvato-adscendentibus, 

 prominentibus ; racemis $ axillaribus, solitariis, usque ad 30 cm 

 longis, floribus numerosis, breviter pedicellatis, sepalis petalisque 

 circiter 3 mm longis. 



A tree, the branchlets and the leaves on the midrib and lateral 

 nerves on the lower surface appressed-hirsute, the staminate 

 racemes densely ferruginous appressed-hirsute. Leaves oblong, 

 subcoriaceous, 12 to 22 cm long, 3.5 to 7 cm wide, the upper 

 surface pale-olivaceous, smooth, shining, the lower pale, sub- 

 glaucous, the base acute, the apex slenderly and acutely acum- 

 inate, the acumen 1 to 2 cm in length; lateral nerves 3 or 4 

 on each side of the midrib, prominent, curved-ascending, the 

 reticulations distinct; petioles 1 to 1.5 cm long. Male racemes 

 axillary, solitary, 15 to 30 cm long, apparently floriferous 

 throughout, but the lower flowers caducous. Pedicels pubescent, 

 about 1.5 mm long. Sepals three, elliptic-ovate to elliptic, 2.5 

 to 3 mm long, appressed ferruginous-hirsute. Petals 5, mem- 

 branaceous, oblong-ovate, acute or somewhat acuminate, some- 

 what pubescent, the basal scale densely ciliate, about 1 mm in 

 diameter. Staminal column glabrous, 2.5 to 3 mm long, slender, 

 somewhat thickened upward ; anthers five, 1 mm long, forming a 

 depressed-globose head. 



Sarawak, Baram District, Miri River, Hose 501, January, 1905. 



The second species of the genus to be reported from Borneo, readily 

 distinguished from the other described forms by its slenderly and sharply 

 acuminate, few-nerved leaves. Hose 430 possibly represents Ryparosa longi- 

 pedunculata Boerl., a Javan species, but the flowers are quite too young to 

 warrant a definite determination of it. 



VIOLACEAE 



RINOREA Aublet 



RINOREA ANGUIFERA (Lour.) O. Ktze. var. NERVOSA (Capit.). 



Alsodeia echinocarpa Korth. var. nervosa Capit. in Bull. Soc. Bot. 

 France 57 (1910) 394. 



Sarawak, Native collector 488, 878, 1870 (Bur. Sci.) ; Samatan, Fox- 

 worthy 168, May 2, 1908. 



The above specimens are apparently referable to Capitaine's variety, 

 which is here transferred to Rinorea anguifera. Medusa anguifera Lour., 

 Fl. Cochinch. (1790) 406, supplies the oldest specific name for the species.
