Specimens caught my eye because they have white rather than yellow coloured ray florets. Not seen that before. This colour variant grew with the more usual yellow-flowered race.

Common along roadside on papa mudstone and associated colluvium / alluvium. Shrubs to small trees up to 6 m tall; branches spindly, leaves patent, grey-green (not seen in in these images as camera doesn't captrure that colour well); flowers 15-20 mm diameter, mostly white sometimes with a faint central pink tinge / blush.

Locally common on Papa Mudstone cliffs. Shrubs to small trees up to 6 m tall. Branches spindly, often pendulous, flowers 15-20 m m diameter, leaves patent, glaucous (colour not captured accurately by camera). Flowering heavily along riversides and adjacent Papa country.

Occasional plants noted with peltate leaves but also with dark maroon petioles - so blurring the distinction between subsp. excelsum (dark maroon petioles but cordate leaves) and subsp. peltatum (green petioles and some peltate leaves).

Pennantia baylisiana x P. corymbosa (known also as P. 'Otari Debut').

One of the more bizarre plantings on the island. A single tree growing in old orchard. Obviously a recent planting on the island as this hybrid (which first appeared spontaneously near the parent species at Otari Native Plant Gardens, Wilton, Otari) has only been known about since the late 1980s.

Leptospermum aff. scoparium (a). Locally common along roadside - growing syntopically with upland race of Leptospermum scoparium s.s, and in places forming occasional hybrids.

At this site Leptospermum scoparium s.s. had finished flowering, putative hybrids almost so, whereas L. aff. scoparium (a) was still in full flower.

Habitat image (last image) shows flowering Leptospermum aff. scoparium (a), most of the Leptospermum in this image are L. scoparium s.s., the sparsely flowering shrubs are the putatively hybrid plants.

= Icarus filiformis (A.Cunn.) Gasper et Salino

At what I assume is the southern limit of this species. Despite searching I have still only seen this fern at this location on the Chatham Islands. At this site it is locally abundant.

Common though mostly in taller coastal vegetation fringing the inner shrubland (forest) of the island. Often found growing through harapepe (Phormium tenax) and Ficinia nodosa.

Locally common in a recently landscaped and planted garden surrounding a new housing area. Almost certainly arrived as a pot contaminant from nursery stock used in this planting.

Common with Kunzea tenuicaulis, K. robusta, K. serotina aroudn active geothermal vents. Specimens with spindly growth habit, sparingly branched, branches often pendulous. Flowers with unusually narrow petals.

Local, small patch weedy in herbicide sprayed lawn margin under macrocarpa (Hesperocyparis macrocarpa). Sunburnt in soil with weeds: Cerastium glomeratum, Lapsana communis, Lysimachia arvensis, Trifolium dubium and Veronica spp.

Thrilled to find a wild flowering M. carminea vine beside the track. The vine was growing on a tall tree fern trunk (no fronds) that had snapped near the base. Possibly from the weight of the vine.

A M. carminea vine was planted at Arataki Visitor Centre nearby over the hill, about 10 years ago. Wondered if there's a possibility the wild vine self-seeded from the planted vine?

July 2019 update: current status of the vine, looked dead but showing signs of life: https://inaturalist.nz/observations/28712258

Maybe Veronica calycina?

Found at the same location as a flowering V. calycina obs: https://inaturalist.nz/observations/20149818

No flowers. Fruit forming, leaves larger. Many plants growing in a 'creeper' way on a weedy access lane in native bush. Specimen in photos sent to Auckland Museum.
