Parinarium.'] LI. ROSACE JE. (J. D. Hooker.) 309 



Petals 5, sessile or clawed, deciduous. Stamens 6-00 , filaments united into an 

 incomplete ring at the base, or connate into an unilateral bundle, all perfect or 

 some without anthers. Carpels 1 (rarely 2), adnate to one side of the calyx- 

 tube, 1-2-celled ; style basal, filiform ; ovules 2 collateral or 1 erect. Drupe 

 spherical oblong obovoid or ovoid, with a 1-2-celled 1-2-seeded coriaceous 

 woody or bony stone. Seeds erect, testa membranous, cotyledons large fleshy, 

 radicle small inferior. DISTRIB. About 40 species, natives of the tropics of 

 both worlds. 



The Indian species of Parinarium are very imperfectly known and are probably 

 referable to several genera distinguishable by their fruit more than by any floral 

 character. Of these, P. costatum, polyncurum, oblong if olium and -nmltijlorum, may 

 form one genus with a 2-celled 2-seeded drupaceous fruit and short stamens. 

 P. nitidum another, with 1 -celled hardly drupaceous coriaceous fruit and short 

 stamens ; and P. asperulum a third, with a globose 1 -celled very hard drupe, 

 glabrous, containing a solitary large glabrous seed with a solid ruminated -em- 

 bryo. The seeds of P. indicum and travcmcoricum are unknown. P. Jackianum, 

 Benth. (Petrocarya excelsa, Jack), must, if Jack's account of the drupe being included 

 in the enlarged calyx and having superposed cells be correct, constitute a fourth 

 genus. 



STTBGEN. 1. Grymania, Presl, (Gen.) Leaves eglandular or 2-glandular 

 at the base. Stamens equalling or shorter than the calyx-lobes, forming an 

 imperfect ring. Drupe oblong or obovoid with a very thick 2-celled stone, 

 the cells lined with soft wool. 



* Leaves eglandular at the base, grey or dirty ivhite beneath, with numerous 

 stout veins. Stamens 6-10, singularly inserted. 



1. P. costatum, Blume ? ; leaves 2-4 in. elliptic-oblong obtusely 

 acuminate shining above, base acute, nerves 8-10 pair, petiole rather slender.

Eastern Peninsula, MALACCA, and Government Hill, PENANG. Maingay. 

 .? Burma, Kurz. DISTRIB. Sumatra. 



A tree 15 feet (in Penang). Branches slender ; bark pale in the Malacca spe- 

 cimens, dark with minute lenticels in the Penang one ; petiole 3-3 in. Panicle effuse, 

 much branched, clothed with soft tomentum ; branches slender ; bracts oblong- 

 lanceolate. Flowers \ in. long, shortly pedicelled. Calyx-tube clothed within with 

 long deflexed hairs; tube longer than the lobes. Petals obovate, ciliate, equalling 

 the- calyx-lobes. Carpels 2 ; ovaries densely tomentose. Fruit (of Penang specimen) 

 f-1^ in. long, rounded at the apex, when dry minutely wrinkled and covered with 

 white scurfy spots. Seeds not seen. But for the smaller leaves with more acuminate 

 points, they agree with P. sumatranum, Benth. I have seen no specimen of Blume's 

 P. costatum. 



2. P. - polyneurum, Miq. Fl. Ind. Bat. Suppl. 306 ; leaves 4-8 in. 

 elliptic-oblong obtusely acuminate shining above, base rounded, nerves 12-16 

 pair, petiole rather slender. 



MALACCA, Griffith; Maingay (Kew Herb., 622). DISTRIB. Sumatra. 



A larger plant than P. costatum, differing in the form and size of the leaves and 

 number of nerves ; the inflorescence and flower are very similar indeed ; the bark of 

 the branches is black with numerous lenticels, which is hardly the case in the 

 Sumatran specimens. 



3. P. oblong ifolium, Hook.f. j leaves 6-10 in. oblong or linear-oblong
