SAURAUIA HETEROSEPALA sp. nov. 



Frutex, ramulis junioribus plus minusve adpresse squamulosis ; 

 foliis oblongis ad oblongo-obovatis, usque ad 24 cm longis, acumi- 

 nata, basi acutis, junioribus subtus ad costa nervisque parcissime 

 adpresse squamulosis, vetustioribus glabris, laevis, nitidis, oliva- 

 ceis, margine minute incurvato-serrulatis, nervis utrinque 10 ad 

 13, pei spicuis ; floribus e axillis defoliatis et caulinis, superioribus 

 solitariis, tenuiter pedunculatis, ebracteolatis, inferioribus depau- 

 perato-cymosis, bracteolatis ; sepalis glabris, binis exterioribus 

 latissime orbiculato-ovatis, rotundatis, circiter 8 mm longis et 

 latis, interioribus contorto-imbricatis, distincte longioribus; 

 ovario glabro, stylis 3, infra connatis. 



A shrub, ultimately glabrous or nearly so, the young branchlets 

 with few, scattered, irregular, ovate to suborbicular, appressed, 

 pale-brownish scales, with similar ones on the midrib and nerves 

 of the younger leaves and on the peduncles, the older leaves gla- 

 brous. Leaves oblong to oblong-obovate, 10 to 24 cm long, 4 to 9 

 cm wide, base acute, apex acuminate, margins minutely incurved- 

 serrate, olivaceous and shining on both surfaces when dry, 

 chartaceous; lateral nerves 10 to 13 on each side of the midrib, 

 prominent, the reticulations slender, close, subparallel; petioles 

 1 to 2 cm long, sparingly scaly. Flowers in the axils of fallen 

 leaves and from the branches and trunks, the upper ones solitary, 

 ebracteolate, the lower ones in depauperate, few-flowered cymes, 

 the pedicels up to 2.5 cm long. Sepals distinctly unequal, all 

 glabrous, rounded, the outer two broadly orbicular-ovate, about 

 8 mm long and wide, the inner three twisted-imbricate, about 

 10 mm long and 9 mm wide. Ovary glabrous; styles united 

 for the lower 3 mm, the arms 3, about 4 mm in length. Bracts 

 on the lower inflorescences oblong-lanceolate to oblanceolate, 

 acute to acuminate, glabrous, 5 to 8 mm long.

 Clemens 9812, October 28, 1915, the fruit green. 



The alliance of this species is apparently with the Javan Saurauia 

 leprosa Korth., from which it is readily distinguished by its inflorescences 

 and floral characters. 



SAURAUIA HOSEI sp. nov. 



Frutex vel arbor parva ; foliis oblongis, usque ad 43 cm longis, 

 chartaceis, olivaceo-brunneis, acuminatis, basi rotundatis, mar- 

 gine spinulosis, nervis utrinque circiter 14, subtus prominentibus, 

 curvatis, anastomosantibus, supra glabris, subtus ad costa et 

 nervis et reticulis parce setosis atque pubescentibus, setis tenui-
