Flowering Plants · Dicotyledons Malvales, Capparales and Non-betalain Caryophyllales

From the reviews:

" ... a contribution fully worthy of the tradition of Adolf Engler, a book that will stand the test of time and be of extraordinary use for decades to come." (Peter H. Raven, Director, Missouri Botanical Garden) 

"The volume is an excellent summary of our knowledge of classification and it is updated with numerous recent references. ... The volume has a clear outline of data and good references, and I find it very useful, both for teaching, as well as for research.  ... The key to genera is very helpful for identification purposes and has much potential for use in the herbarium. The series represents the most detailed account of seed plant diversity at this stage. This is a series everyone concerned with phylogeny should have in his library." (Plant Systematics and Evolution)

"I have been eagerly waiting for this edition to come out and I am not unhappy with the result. … The volume has a clear outline of data, and good references, and I find it very useful, both for teaching, as well as for research. … The key to genera is very helpful for identification purposes and has much potential for use in the herbarium. … This is a series everyone concerned with phylogeny should have in his library."
