rex. | CYPERACEAE. 251 
An immense genus of probably over 1000 species, of world-wide distribution, but 
st abundant in temperate regions, rare in the tropics, save on high mountains. Of 
> 55 species found in New Zealand, no less than 37 are endemic, the remaining 18 
ing mostly widely spread. 
In revising the New Zealand species for this edition I have found Dr. Kukenthal’s 
onograph of the genus, issued as Heft 38 of the Pflanzenreich, of very great assistance. 
t the same time, I have been unable to follow him in all his conclusions. Few New 
saland botanists will agree with him in reducing Carex secta, C. virgata, and 
. appressa to one species; or in uniting C. Cockayniana and C. semi-Forstert to 
_ Forsteri ; and there are similar instances of less moment. But these are matters of 
jnor importance, and do not detract from the many excellencies of the work. 
Several species of Carex have become naturalized in New Zealand. Among these 
ay be mentioned the European C. divisa Huds.; C. muricata L.; C. flacca Schreb. 
!, glauca Scop.); C. panicea L.; and the Australian C. longifolia R. Br.
