Lignicolous on Eucalytpus sp. lignum. Large orange, fruiting bodies - a very common fungus in Autumn along this creek walkway
A single plant established on margin of polluted creek. Fronds large (adult foot with jandal for scale) immature but densely invested in glandular hairs - subsequent collections of mature fertile fronds (these with conspicuous reflexed membranous indusia) lodged in AK
Local - growing on exposed basalt lava flow above Meola Creek. Flowering profusely.
Cultivated - ex Surville Cliffs. Decumbent utlramafic race of Hibiscus diversifolius last seen in the wild in 1996 and now presumed extinct in the wild. Differs for H. diversifolius subsp. diversifolius but decumbent growth habit, and less divided (not palmatisect) leaves.
Flowering shrub growing on basalt lava flow about Meola Creek headwaters.
Locally established on retaining wall between old cottage and Thomas Building. Here this fern has persisted despite the grounds man's bets efforts to eradicate it for the last fifty of so years.
This fern is also locally present in other parts of Auckland, Hamilton and Tauranga
Naturalised along footpath - this is the diploid race incorrectly attributed to Hibiscus trionum (an African tetraploid - see Craven et al 2011). Currently treated as naturalised to New Zealand, this race may infact be indigenous (if not endemic) as so far I have been unable to match it to any of the other races of H. trionum sensu lato present in Australia, Europe or the USA.
Irrespective - at this location, this plant was clearly naturalised.

One flowering adult growing in cracked pavement between street foot path and residential car park. Clearly naturalised. Voucher lodged in AK.
Abundant - parasitic on kahikatoa Leptospermum aff. scoparium (a) (the most common race of kahikatoa in the Auckland region and not the same as L. scoparium s.s) on margin of spring. Origin unclear but believed to have been accidentally introduced into Western Springs Park over 20 years ago. Cassytha is locally established in several parts of great Auckland now.
Naturalised - origin unclear - appeared as gutter weed. Persisted for seven years until council finally killed it. This species was not cultivated nearby but is occasionally seen in cultivation around Auckland. In the 1970s Graeme Platt sold it from his then Albany Nursery, stating plants came from the Chatham Islands.
Naturalised from material purportedly cultivated on the grounds from a plant bought from Raoul Island. Locally common in former shade house and holding pen for plants held fro planting out by ground staff. This site and habitat destroyed when a new building was built over it. Since 2010 no further specimens of this fern have been seen on the campus.
Locality: NEW ZEALAND AK, Auckland Central, Albert Park
Habitat: Ulmus sp.
Identification: Edwardsiana lethierryi (Edwards, 1881). Male. Several others observed (adults, nymphs and exuviae).
Numerous vines and seedlings present in Camellia hedge between properties. Calystegia marginata appeared in this area in 2011, initially as a single plant. Its origins are unclear but it is probably indigenous to the area as I have also seen it in several sites around Auckland. The distinctive pale yellow-green, 'fish-tailed' often lobed sagitate leaves, and (not seen here) small white flowers, borne on flattened peduncles, and the small tuberculate seeds are diagnostic.
Saxicolous on concrete pavers, pathways and mortar on stone walls. Abundant. Thallus wanting, greenish-grey, irregularly, (often much) cracked. Apothecia sessile often appearing immersed, orange-red (K+ purple). Very abundant lichen of inner Auckland on concrete pavers, pathways, pylons etc. Known locally as 'chewing gum lichen'.
Locality: NEW ZEALAND AK, Auckland Central, Alten Reserve
Habitat: Ulmus sp.
Identification: Edwardsiana lethierryi (Edwards, 1881). Male.
Locality: NEW ZEALAND AK, Auckland Central, 10-12 Symonds Street (University of Auckland City Campus, Human Sciences Building courtyard).
Habitat: On cultivated cycads, infested with various coccoids.
Identification: Telsimia subviridis (Blackburn, 1892). Female. ID based on the literature (Ślipiński, Pang & Pope, 2005). ID a little tentative at species level.
