PLANTiE JAVANIC^ RARIOUES. 613 



apice extus areola circulari (clialaza) insignitum : intlmum 

 (integumentum interius) membranaceum. Albumen nucleo 

 conforme, bipartibile, amygdalinum, album. Embryo 

 erectus, fere longitudine seminis, albus. Cotyledones lati- 

 tudine albuminis idque bipartientes, foliacese : Radicula 

 hilo proxima, brevis, subovata. 



Fterocymhium javanicum, according to Dr. Horsfield, 

 grows scattered among other trees in the luxuriant forests 

 which, at a small elevation above the sea, cover many of 

 the plains in the central and eastern districts of Java. 



The native name is Wining or Kemoonoong.

 sessile and the anthers closed. Fig. 5. An anther seen in 

 front. Fig. G. The same, seen from behind. Fig. 7. The 

 column thickened at top, which in Fig. 8 is seen divided 

 into ten teeth. Fg. 9. One of the pistilla, cut longitudi- 

 nally to show the two erect collateral ovula. Fig. 10. The 

 half of an expanded flower, in which the column is elon- 

 gated. Fig. 11. The base of a carpel, with its single seed. 

 Fig. 12. The seed, deprived of its outer integument.

SterculiacejE, to which Pterocgmbium evidently belongs, 

 was first proposed as a distinct natural family by Ventenat 

 in 1804;-' his only character separating it from Malvacece 

 being the presence of albumen surrounding the embryo, 

 and from Tiliacem its monadelphous stamina. 



In 1814,^ in suggesting the formation of Natural Classes 

 of plants and proposing Malvacece as one of these classes, 

 I referred Sterculiacece to it, but regarded the order as
