Pandorea sp. climbing vine

Description:

Amongst the massive blue gums and other large trees, I spotted this very delicate vine. I recognise the leaf shape of this young specimen rather vaguely, but after some investigation I'm reasonably confident this is a species of Pandorea, of the family Bignoniaceae (see notes). Probably the most common species is Pandorea pandorana, which ranges in habit from a scrambling plant to a vigorous vine, growing on larger trees in forested habitats. It has glossy green leaves arranged oppositely along the stem. The juvenile leaves (seen here) are finer and have serrated margins, and more finely divided into 7–13 leaflets. Flowering occurs in spring, and the tubular or funnel-shaped flowers are highly variable in colour. However, until I actually see the flowers and fruits, I'm unable to nominate an exact species.

Habitat:

Spotted climbing a Sydney blue gum (Eucalyptus saligna), in a small clearing on the banks of Dalrymple Creek, along the North Branch Trail. This area is known as the "Goomburra Section" of Main Range National Park. The park forms part of the Gondwana Rainforests of Australia World Heritage Area. Subtropical rainforest, but this spot had good sunlight at various times of the day, in what is otherwise a cool, damp, well-shaded area. The various Pandorea species are hardy and said to thrive in a variety of soils and climate conditions.

Pandorea pandorana - https://www.revolvy.com/page/Pandorea-pa... Pandorea pandorana ssp. austrocaledonica - https://www.revolvy.com/page/Pandorea-pa... Pandorea floribunda - http://www.floragreatlakes.info/html/rfs... Pandorea jasminoides - https://www.revolvy.com/page/Pandorea-ja... Distribution and occurrence: There are 6 Pandorea species worldwide, 3 species of which are endemic to Australia. That coincides with the 3 species documented as occurring in Main Range National Park - https://wetlandinfo.des.qld.gov.au/wetla... ....but exactly which 3 seems to vary depending on the source. Well, we have 6 to choose from.
