The

The monograph now presents in detail the Dyce system for classifying and
naming the Polystichum cultivars.
There is descriptive text and abundant illustration of the three British
species of shield fern (Polystichum aculeatum, P. lonchitis
& P. setiferum) and their numerous varieties.
This work is now the definitive reference for the confident identification
and accurate naming of the cultivars in this horticulturally significant
group of ferns.
The Index contains listings of the following numbers of cultivars of the
three British species of Shield fern: P. aculeatum - 16, P.
lonchitis - 1 and P. setiferum - 141.
Illustrations are mainly b/w photographs of fronds or pinnae to show the
critical diagnostic features.
