clothed with the bases of the old leaves. Stems 3-I5in. high or more, 
branched from the base, erect or spreading, glabrous or sparsely clothed 
with whitish hairs. Leaves varying with the size of the plant ; in large 
specimens the radical leaves are several and rosulate, 3-4 in. long, with 2-6 
pairs of leaflets, the terminal leaflet usually the largest, remiform or orbicular, 
with 3-5 irregular shallow lobes or sinuate; the lateral often oblique, 
3-dentate or -crenate. Cauline leaves 3-2 in. long, 2-3-jugate or more rarely 
1-jugate. In small specimens the size of the leaves and the number of the 
leaflets are much reduced; but the terminal leaflet is generally larger in 
proportion to the others. Racemes terminal, 6-15-flowered. Flowers

Nortu AND Sours Istanps, CuatTHam Istanps, Stewart Isuann: From the Three 
Kings Islands and the North Cape southwards, abundant in suitable localities from 
sea-level to 6500 ft. Var. uniflora is particularly abundant near the sea, but it is also 
seen in mountain distr?-+s, where it was originally discovered by Mr. Colenso. 
In nearly all general works on the New Zealand Flora this well-known plant has 
been referred to the northern OC. hirsuta. It is so closely allied thereto that it is not 
without considerable hesitation that 1 now follow O. E. Schulz, in his recent monograph 
of the genus, in altogether removing C. hirsuta from the list of New Zealand species, 
and in reviving Forster’s name of heterophylla for our plant. Of the varieties of 
C. hirsuta admitted in the last edition of this work, var. debilis I now regard as the type 
of C. heterophylla ; var. corymbosa is re-established as a distinct species; and var. sub- 
carnosa is treated, as proposed by Schulz, as a variety of the South American C. glacialis 
DC. Var. uniflora remains, but will in all probability prove to be a distinct species 
But the mountain forms of the species are sti]! much in need of a careful study and 
description by resident botanists. :
