Abstract
A CONVENIENT summary for determining the orders of flowering plants is a much required desideratum. The difficulties in compiling such a summary are very great, not the least being due to the impossibility of defining the limits in certain cases between allied orders. Mr. Adams has not attempted such details, preferring to leave out a large number of orders and to sacrifice difficult distinctions to brevity and general utility. With regard to the statement that the book is after Engler's system, this applies only to the names of the orders; the method of separation is purely artificial. Thus, in the Archichlamydeie, parasites and insectivorous plants are first eliminated, then consideration of the vegetative organs provides the next stages in differentiation. So far as practical tests have been applied with a few orders, the tables have given quite satisfactory results.
