 and 46, September and October , 1851. 



This September contains two botanical articles : these are inti- 

 tuled : — 



' Observations on the Aflfinities of Olacaceae ; by John Miers, Esq., 

 F.R.S., J.Li.S. 



' Remarks on Dickieia ; by John E-alfs, Esq.' 



The former of these is a paper exhibiting the most profound 

 research, and does infinite credit to its talented and most industrious 

 author, whose object is to show that the published opinions of botanists 

 on this hitherto obscure point are not so widely discrepant as they 

 seem. " The family of the Olacaceae, first proposed by Mirbel, in 

 1813, under the name of Olacineae, was placed by him near the Au- 

 rantiaceae : Jussieu stationed it in proximity with the Sapotaceae, 

 while DeCandolle, following the views of Mirbel, arranged it close to 

 Aurantiaceae, a conclusion adopted by most succeeding botanists, and 

 among these Endlicher and Meisner, who disposed it with Auranti- 

 aceae, Meliaceae, Humiriaceae, &c., in a class called Hesperides. 

 Brongniart however follow^ed the original views of Mr. Brown, in 

 regard to the affinity of Olax with the Santalaceae ; but, upon less 

 satisfactory grounds, he associated with these the Loranthaceae, ex- 

 cluding at the same time Ximenia from the family. Dr. Lindley, in 

 his ' Nixus Plantarum ' and ' Natural System,' offered a new view, by 

 placing it, under the designation of the Olacaceae, in the same alliance 

 wnth the Pittosporaceae and Vitaceae, for which position few and not 

 very satisfactory reasons could be offered. Mr. Bentham, in an ex- 

 cellent memoir on the Olacineae (Linn. Trans, xviii. 676), proposed a 

 new arrangement of the order into three distinct tribes, adding seve- 

 ral new genera, together with his ingenious views in regard to its 

 affinities, when he justly denied its relation with the Aurantiaceae, 

 although he admitted its approach to the Humiriaceae, considering
