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.
Terrestrial. Threat to well drained sites, e.g.. sand dunes.
Large shrub or small tree to about 10 m high. Leaves narrowly elliptic with densely serrate margins. Deep shining green above and white beneath. Inflorescence mostly 9-12 cm long, erect, forming a broadly cylindrical cone, pale green or pale greenish yellow. Fruiting cone woody, with brown felty indumentum persisting in lower part, valves opening widely to expose seed. Cones may persist on the tree a long time after flowering.
Banksia species are quite distinctive within the Proteaceae, as the flower spikes consist of hundreds of tubular flowers arranged in rows. There are several Banksia species in New Zealand, B. integrifolia can be identified by the yellow-greenish yellow inflorescences and the obovate leaves 4-10 cm long, woolly underneath.
May, June, July
Long-lived tree. Spreads by seed. Many seeds are produced, may require fire for mass germination. Dispersed by people, gravity, possibly expulsion during fire
