of wliicli but few species are known, natives of Ceylon,' consists of 

 climbing shrubs, whose curved branches bear alternate leaves, the 

 petioles of which are channelled and dilated at the base to ensheath 

 the branch to a variable extent. The secondary nerves of the blade 

 are parallel and very near one another.- The spikes of flowers are 

 grouped into terminal or axillary ramified bunches, each flower is 

 accompanied by two unequal lateral bracts.^ 



The genus Tet racer a^ has the perianth oi Hihhertia or Schimacheria — 

 i.e, usually five imbricated sepals,^ and as many imbricated petals/' The 

 indefinite stamens, arranged all round the receptacle as in C//dandra, 

 have a peculiarity, which, of no great importance in itself,^ is yet useful 

 in practical determinations. The filament, corrugated in the bud, is 

 gradually dilated towards the tip, and bears an anther whose cells

^ All these parts are rich in a blackish colour- 

 ing matter. 



^ These flowers are (as we have stated) nni- 

 lateral, like those of many species of certain 

 sections of Hihhertia ; it is very diflicult to find 

 characters of any valne hy which to distinguish 

 clearly Sckumacheria from these.

* The imbrication varies, but is often quin- 

 cuncial. We often observe si.\, or more fre- 

 quently four, sepals, of which the outermost is 

 broader and thicker than the rest. 



^ One or two petals may be wanting, as is 

 very frequently the case in Delima. 



7 We shall see that too absolute a value has 

 been assigned it, and that in the groups Ilih- 

 hertieo' and Dillciiicir are plants whose authors 

 have similar dilated connectives.
