becomes only a shallow pit, or even a horizontal platform. These 

 species have been made into a genus, Jlabzdia,^ which, as all its other 

 characters are the same, can merely be considered as a section of the 

 genus Xi/lojjia, containing only Old World species. 



Again, in other species of this genus, such as X (jrumiijlora 

 A. S. H.,^ lucida H. Bn.,^ &c., it happens that, as in many other 

 genera of this order, the outer stamens, instead of being fertile, are 

 converted into small petaloid scales (fig. 2G4). 



Even the usual character of the corolla m.ay to a great extent be 

 wanting. In several species from tropical Asia, or the north of 

 Oceania, the petals, all nearly similar to one another, lose much of 

 their length and thickness. Each corolla forms only an obtuse cone ; 

 the petals are sessile, nearly triangular, and of about the same thick- 

 ness from base to apex. The inner ones alone have slight lateral 

 notches at the base, through which, as in the typical Xi/Iopias, we 

 see the pieces of the androceum. The small flowers of X. Vieillardi,^ 

 from New Caledonia, possess this conformation of the llower-bud in 

 the highest degree — evidently a step towards the form of the corolla 

 in certain Vnoiiece. 



Finally, two remarkable plants from the east of Africa, formerly 

 ascribed to the genus Aiioiia, must also be referred to Xylopia as 

 forming a particular section to which we shall giv^e the name of 

 Pseudanona. These are X. auqjlexicaulis^ and LaiiiarcJcii.^ Their
