In Sparmannia the arrangement is similar, except that the fer- 

 tile stamens are more numerous, and, together with the stami- 

 nodes, are antisepalous, not antipetalous.

The diversities in the relative position of the floral envelopes 

 and of the parts of the andrcecium in Tiliacese seem therefore to 

 be associated with abortion and suppression of petals, suppression 

 or multiplication of stamens, or with subdivision of the individual 

 stamens — some of the branches being fertile, others anantherous. 

 But all these matters require to be investigated in fresh flowers 

 and in various stages of development. This remark applies even 

 more forcibly to the Olacaeese. 



2. Olacacece. — It must be premised that this order, as understood 

 by Bentham and Hooker, is a rather heterogeneous conglomerate 

 of genera, and that doubtless in course of time considerable re- 

 arrangement will be found necessary ; indeed this has already been 

 partially effected by Miers, Baillon, and others t. 



From the peculiarities of structure and arrangement in this 

 order, from the occasional uncertainty as to what is to be con- 

 sidered calycode and what calyx, from the difficulty of accurately 

 determining the relative position of the parts in pressed and dried 

 flowers, from the few opportunities presented to the home botanist of 

 examining fresh specimens of this order in gardens, and from other 

 causes, it is unsafe to rely on the diagrams and descriptions given
