Zealand species form almost impenetrable thickets as far south as Campbell Island. Many of the 

 species are difficult to discriminate, owing to their great variability. The student should endeavour 

 to obtain, in addition to male flowers, female flowers and fruits taken from the same plant, as the 

 fruit is often of great importance in the determination of species. The calyx is absent in the male 

 flower of many species, but is invariably present in the female ; in the former the corolla is most 

 frequently funnel-shaped, in the latter it is usually tubular. In many of the small-leaded species 

 the male, or both male and female flowers are seated in a kind of involucel, which usually is 

 unequally 4-lobed, and is easily mistaken for a calyx, especially in the male flower, which is often 

 destitute of this organ ; one or more pairs of connate stipules are frequently developed below the 

 involucel. The New Zealand species have been admirably monographed by Mr. T. F. Oheeseman 

 in Trans. N.Z.I, xix., and in many cases I have gladly availed myself of the results of his 

 work. Without doubt additions will be made to the genus, especially from alpine and subalpine 

 districts.
