Subordinate to the " series " are f( cohorts/' or groups of orders of equal 

 value, though with different limitations, to the " alliances " in Lindley's 

 1 System.' The only point which requires explanation here is the series 

 Disciflorce, which includes those polypetalous hypogynous orders in which 

 there is a conspicuous hypogynous disk or series of glands, into or be- 

 tween which the stamens are inserted. 



Braun's System. In Germany the classification of A. Braun is 

 now much followed. The following are bis main groups of Phane- 

 garns as modified by Hanstein, Sachs, and others :

Juliflorse correspond nearly to Amentales, and are characterized by 

 spicate or amentaceous inflorescence, diclinous flowers, and mono- or 

 achlamydeous flowers. Monochlamydeae have a well-marked perianth 

 of one row ; Aphanocyclse have calyx and corolla, the parts of the flower 

 (except in some cases the carpels) being arranged in spiral cycles. In 

 Tetracycla3 the parts of the flower are in whorls. This group comprises
