Rhoeadales are culled Papaverales in Gray's Manual and also in 

 Britton and Brown's Flora. Instead of Opuntiales, Warming and 

 also Hutchinson used the form Cactales. The names Passillorales, 

 Mvrtales and Unibellales, as used by Bentham and Hooker, seem 

 preferable to the names of Rendle. The termination -florae, as 

 in Thalamiflorae, might well he reserved, as by He Candolle and 

 by Bentham and Hooker, for groups of Angiosperms Larger than 

 orders, if such become established. If we make such nomen- 

 elatural changes only, Rendle's list of orders might read as follows: 



Ranales, Papaverales, Sarraceniales, Parietales, Passillorales, 

 ( iuttiferales, Mah'ales, Euphorbiales, Geraniales, Rutales, Sapin- 

 dales, Celastrales, Rhamnales, Rosales, Mvrtales, Cactales, Um- 

 bellales. 



Rendle's classification clearly combines ideas from the great his- 

 toric systems. What changes would he needed if we adopt in part 

 ideas from Hutchinson and other botanists? An answer is at- 

 tempted in the following arrangement : 



Carpels Separate or Single 



A . Magnolia Group 



Ranales 

 Rosales 

 Protealcs? 

 Carpels United, Rarely Single 



Placentation mostly Basal or Parietal, rarely Axile 



B. Ulmus Group G. Cistus Group 



I [amamelidales Parietales 



Urticales Cactales (inch Aizoac?) 



Euphorbiales? Papaverales 



Rafales Sarraceniales 



Casuarinales? Aristolochiales 



Passiflorales (inch Cucurb.) 

 Placentation Axile or Central 



D. Geranium Group E. Myrtits Group F. Dianlhus Group 



Guttiferales Myrtales Caryophyllale s 



Malvales Umbellales Polygonales 



Rutales Piperales? 



Geraniales 



Celastrales 



Sapindales 



(incl. Jugland.?)
