 PLANTS JAVANIC.E RARIORES. 613

apice extus areola circulari (chalaza) insignitiim ■ intimum (integumentum interius) membranaceum. Albumen nucleo conforrae, bipartibile, amygdalinum, album. Embryo erectus, fere longitudine seminis, albus. Cotyledones lati- tudine albuminis idque bipartientes, foliacese : Radicula hilo proxima, brevis, subovata.

Pterocymbium 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.

Tab. XLV. Fig. 1. A branch bearing leaves. Fig. 2. A portion of the panicle, bearing ripe fruits. Fig. 3. An unexpanded flower. Fig. 4. The same, slightly magnified, opened longitudinally, the sexual organs being at that period sessile and the anthers closed. Fig. 5. An anther seen in front. Fig. 6. The same, seen from behind. Fig. 7. The column thickened at top, which in Fig. 8 is seen divided into ten teeth. Fig. 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. Fig. 13. The same, after the removal of the inner integu- ment. Figs. 14 and 15. The embryo, with its bipartite albumen.

Sterculiace^, to which Pterocymbium evidently belongs, was first proposed as a distinct natural family by Ventenat in 1804 j 1 his only character separating it from Mahacea being the presence of albumen surrounding the embryo, and from Tiliacece its monadelphous stamina.

In 18 14, 2 in suggesting the formation of Natural Classes of plants and proposing Malvacece as one of these classes, I referred Stercidiacece to it, but regarded the order as
