ALLIANCES OF PLANTS. 



211 



Alliance 5. Cattitrichales. Carpels several. 

 142. Callitrichaceae. 



Probably the two last alliances ought to be combined. But it is evident that the 

 whole group is so incomplete, that no distribution of the orders is likely to be worth 

 m "f o Y? , e P resent - Achlamydosae join Rectembryosse by Garryaceae, Podostemese, 

 and Callitrichaceae ; and Tubiferosfe by Monimiales. ' 



GROUP III. TUBIFEROS.E. 



Alliance 1. Santalales. Flowers epigynous. 



143. Santalaceae . Sedative (Sandal 

 Wood).

 plants. 



Alliance 5. Penaales. Carpels several. 



152. Penaeaceae . Sweetish, nauseous, 

 gummy, resinous 

 (Sarcocol). 



Their tubular calyxes distinguish them at once from all the other groups, except 

 Columnosae ; and the latter are in general clearly characterised by their stamens united 

 into a column. Tubiferosae touch Achlamydosae by Lauraceae, and Columnosae by Aris- 

 tolochiaceae. They are also strongly related to Curvembryosae by Elasagnaceai.
