302 PHANEROGAMIA. 



Whether the Icacinece should form a distinct order, with affinities 

 in some respects different from those of the Olacacece, as is ably argued 

 by Mr. Miers, or whether they may still be arranged as a suborder 

 of Olacacece, is a question which I am not competent to decide. It is 

 merely more convenient on the present occasion to adhere to the 

 older view. 



The Pleuropetalum of Dr. Hooker is several years older than the 

 Pleuropetalon of Blume ; but, since the name of the former genus has 

 already been changed by Moquin-Tandon, on account of its inap- 

 propriateness (the plant being apetalous), the latter should be con- 

 tinued.

 above the calyx, showing the slightly imbricated aestivation of the 

 corolla : 4, of the corolla near the apex, the aestivation there indu pli- 

 cate. 5. A petal, seen from within. 6. A stamen, seen from within. 

 7. The same, seen from without. 8. Vertical section of a flower-bud, 

 through the ovary, showing the two suspended ovules, &c. 9. The 

 pistil, seen from the side which is directed towards the axis of the 

 inflorescence : the calyx torn away from the torus. 10. The same, 

 transversely divided. The details magnified.
