A species manifestly closely allied to the widely distributed Cyathula 

 prostrata Blume, but with entirely differently shaped leaves. In its in- 

 florescence and floral structure it is very similar to Blume's species. 



ANNONACEAE 



PAPUALTHIA Diels 

 PAPUALTHIA SAMARENSIS sp. nov. 



Frutex vel arbor parva subtus foliis ad costa ramulisque dense 

 ferrugineo-pubescentibus ; foliis oblongis, subcoriaceis, usque ad 

 15 cm longis, acuminatis, basi cordatis, aequilateralibus vel 

 leviter inaequilateralibus, brevissime petiolatis, nervis utrinque 

 10 ad 12, subtus cum reticulis primariis prominentibus ; floribus 

 solitariis, longissirhe tenuiterque pedicellatis, circiter 1.5 cm 

 longis, petalis crassissime coriaceis, oblongis, obtusis, extus plus 

 minusve pubescentibus ; carpellis circiter 10, anguste oblongis; 

 stigma capitata, leviter hirsuta. 



A shrub or small tree, the branchlets, petioles, and the midrib 

 on the lower surface densely ferruginous-pubescent. Branches 

 slender, terete, glabrous, dark-brown or nearly black when dry. 

 Leaves subcoriaceous, generally oblong, sometimes a little wider 

 in the upper part than below, rather pale when dry, somewhat 

 shining, 10 to 15 cm long, 2.5 to 4.5 cm wide, apex prominently 

 acuminate, the acumen blunt, base abruptly rounded, cordate, 

 equilateral or slightly inequilateral, the upper surface smooth, 

 glabrous, pale, the lower somewhat pale-brownish; lateral 

 nerves 10 to 12 on each side of the midrib, very prominent, 

 coarsely anastomosing, the primary reticulations lax, prom- 

 inent; petioles about 2 mm long. Flowers solitary, in the 

 uppermost axils, their slender glabrous pedicels up to 11 cm in 

 length. Flowers about 1.5 cm long, smaller when immature, 

 pinkish-white. Calyx-lobes broadly ovate, coriaceous, acute, 

 sparingly ciliate, 2.5 to 3 mm long, forming a nearly triangular 

 calyx. Corolla up to 1.5 cm long, the lobes wholly united for 

 the lower 3 to 4 mm, very thickly coriaceous, externally more or 

 less appressed-pubescent in the lower part, the lobes oblong or 

 narrowly oblong, obtuse, up to 12 mm long, 3.5 to 4.5 mm wide. 

 Stamens indefinite, crowded, 1.8 to 2 mm long, the connectives 

 truncate, concealing the anther-cells. Carpels about 10, nar- 

 rowly oblong, slightly pubescent; style short, slender; stigma 

 obovoid or capitate, somewhat hirsute. Fruit globose, glabrous, 

 dark-brown when dry, shining, about 8 mm in diameter.
