Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Clianthus maximus Colenso
Rare (common in cultivation) small bushy shrub with drooping clusters of red sharp-tipped flowers. Leaves with many pairs of glossy leaflets arranged along a central stalk. Flowers 80mm long. Fruit a green pea-like pod that splits releasing the numerous hard small blotched seeds.

The National Vegetation Survey (NVS) Databank
is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.
Dicotyledonous Trees & Shrubs
Clianthus puniceus var. maximus (Colenso) Kirk
Endemic. North Island. Formerly on Great Barrier Island. Still present in scattered populations from the East Coast of the North Island from Te Araroa south to the northern Hawkes Bay and east to the Te Urewera National Park.
Like the closely related C. puniceus (G.Don) Sol. ex Lindl. this species prefers early to mid successional shrubland habitats dominated by flax (Phormium cookianum Le Jolis, and P. tenax J.R.Forst et G.Forst) and tutu (Coriaria arborea Lindsay) in coastal, lowland and montane habitats. Often found along the tops and bases of unstable cliff faces or rock falls. Some habitats may not be natural, as this species, was said to have been grown by Maori, and many inland associations occur in the vicinity of former pa, kainga, gardens or canoe haul outs.
Shrub 1.5-6 m tall. Wood soft, stems "watery" easily broken. Branchlets semi-erect to weakly ascending, often decurved. Leaves 15-25 cm long, imparipinnate, with 15-30 pairs of subsessile leaflets. Leaflets, dark green, upper surface shiny (very glossy) 150-300 mm, linear-oblong, apex retuse or rounded. Inflorescences racemose, 15-30-flowered, located in leaf axils near branch apices. Flowers 80 mm, dark scarlet. Standard ovate-acuminate, 60 mm, dark scarlet, with a dark maroon (almost black blotch) and usually lacking stripes (these if present indistinct, often dotted; wings 30 mm long, lanceolate-falcate; keel 60 mm long, falcate-acuminate, dark scarlet. Pods long persistent, 80 mm, at first green and turgid, drying black and splitting open for entire length. Seeds numerous, c.1-1.5 mm diam, grey various striped or blotched with black, embedded in wispy grey, floccose hairs.
Closely related to C. puniceus which has mat-green foliage, whose upper leaf surface is often slightly glaucous in colour. C. maximus leaves are dark green, and the upper leaf surface very glossy. C. puniceus flowers are slightly smaller, the standard is conspicuously striped white, and the spur blotched or striped white as well. C. maximus flowers are larger, very dark red, blotched dark purple-black near the base (very rarely with a few faint white stripes) and the spur is uniformly dark red.
May flower throughout the year. However plants are mostly found in flower between August and January

Seed pods may be present at any time of the year
Easily grown from seed, semi-hardwood cuttings, and stem layerings. Plants tend to be short-lived in cultivation (2-4 years), and benefit from hard pruning after flowering. Kaka beak is vulnerable to a range of common garden pests which include slugs and snails, it can be severely defoliated, by these animals, and young plants may be killed completely. Caterpillars, mites - which cause witches brooms, and various fungal diseases will also kill plants. To combat these problems grow plants in fertile, well drained, sunny sites free from surrounding shrubs. Despite its northerly distribution, kaka beak often does best in Southland, and is very tolerant of snowfall, and light frosts.
Though more widespread than C. puniceus this species is now at a very serious risk of extinction. Only 153 mature plants are known from the wild and at all sites they are threatened by a diverse range of introduced browsing animals, diseases, and natural senescence. Many populations occur in low scrub where they are threatened by fire, weed control operations, natural succession, and the unstable, erosion prone nature of the habitats in which they grow.

Life Cycle and Dispersal
Seeds are wind dispersed (Thorsen et al., 2009).
Where To Buy
Now common in cultivation and widely sold. But prior to the early 1990s this species was virtually unknown in cultivation, most if not all horticultural stock then available being referrable to C. puniceus s.s.
