1500-4000 ft. Coral Broom. December—January. 
One of the most remarkable plants in the Dominion; at once recognized by the 
robust deeply grooved branchlets, densely fascicled flowers, and woolly calyx. It 
appears to be confined to arid situations on the eastern slopes of the Southern Alps. 
2. CARMICHAELIA R. Br. 1¢2¢. 
Erect or depressed shrubs, some species attaining a height of 6-10 ft., 
others reduced to broad matted patches hardly rising more than an inch or 
two above the ground. Branchlets flattened or terete, grooved or striate, 
green. Leaves often absent, except in seedlings; when present deciduous 
after the flowers have fallen, 1-foliolate or pinnately 3—5-foliolate. Flowers 
small, in lateral racemes springing from notches on the edges of the 
branchlets, rarely solitary. Calyx campanulate or cup-shaped, 5-toothed. 
Standard orbicular, usually reflexed, contracted into a short claw. Wings 
more or less falcate, oblong, obtuse, auricled towards the base. Keel 
oblong, incurved, obtuse, shorter or longer than the standard. Upper 
stamen free, the others connate into a sheath. Ovary narrowed into a 
slender beardless style ; stigma minute, terminal; ovules numerous. Pod 
small, coriaceous, narrow-oblong to almost orbicular, straight or oblique, 
compressed or turgid, narrowed into a short or long subulate beak; valves 
with the edges thickened and consolidated, forming a kind of framework 
called the replum, from which the faces of the valves come away; or in a 
few species the valves remain attached to the replum and the pod is 
indehiscent. Seeds 1-12, reniform or oblong; radicle usually with a double 
fold. 
A very remarkable genus, confined to New Zealand, with the exception of one 
species found in Lord Howe Island. Its habit is peculiar, most of the species being 
leafless or nearly so when mature, the green flattened or terete branchlets (cladodes) 
performing the funetions of true leaves. The structure of the pod is most exceptional, 
the margins of the valves and placentas being thickened and consolidated into a frame- 
work (replum), to which the seeds are attached. In dehiscence the faces of the valves 
either come away altogether from the replum;, which may persist for a long time with 
the seeds hanging from it, or the valves may separate at one side or end, remaining 
attached at the other. In the four species constituting the section Huttonella the valves 
do not usually separate from the replum, which is frequently incomplete, and the pod 
is thus indehiscent. Had this character been constant, Huttonella might well have 
been kept as a distinct genus, as proposed by Kirk. But fruiting specimens of C.juncea - 
in Mr. Colenso’s herbarium show that the valves occasionally separate from the replum 
in that species, and Mr. Petrie informs me that the same thing occurs in his C. com- 
pacta. 
The discrimination of the species is probably more difficult in Carmichaelia than in 
any other genus in the New Zealand flora, and the student will find it almost impossible 
to name his specimens with accuracy until he has collected most of the species and 
become familiar with their characters. In most cases characters based upon the 
vegetative organs are by themselves useless. The leaves, when they can be examined, 
are singularly uniform; and the branchlets are not only highly variable in width, but 
may be flattened in spring and nearly terete in autumn. The flowers vary in size and 
colour in the different species, but present no important structural modifications. The 
pods afford the most trustworthy characters, and in several cases are quite sufficient 
for the identification of the species. The following analysis of the species is in many 
respects imperfect, and will doubtless require considerable modification. A really 
comprehensive and accurate account cannot be drawn up until the species have been 
carefully studied in the field at different seasons of the year, and in all stages of
