Hoya australis subsp. australis
A variable climbing subspecies with succulent, hairy leaves, documented on rocks and in Australian forests.
This profile follows the subspecies description, keeping it separate from cultivated selections and plants identified only as Hoya australis.
Overview
Hoya australis subsp. australis is a botanical subspecies of Hoya australis. In Flora of Australia, Paul Forster and David Liddle describe it as a vine, occasionally a small shrub, with succulent leaves that vary from sparsely to densely hairy. The species account describes cream flowers with red beneath the central crown. Their 1996 treatment records this subspecies from Torres Strait south to north-eastern New South Wales, on rock outcrops and in several forest types.

What We Know
- Flora of Australia describes succulent leaves up to 15 cm long, with sparse to dense hairs and margins that are not strongly rolled under. These characters are considered together in its identification key.
- The 1996 Australian treatment records rock outcrops, rainforest, vine forest and vine thickets. These are occurrence records, not a controlled comparison of growing conditions in pots.
- The flora reports March–May flowering in its Australian account. That regional observation does not predict a flowering schedule for every cultivated plant.
- Kew’s Plants of the World Online accepts the subspecies. A plant received simply as Hoya australis still needs evidence before assigning it to this subspecies.
What We Are Still Learning
Which cultivated plants have a traceable identification as subsp. australis?
What would help: Original labels, documented source locality or accession records, and leaf and flower photographs tied to the same plant; a voucher-based identification is especially useful.
Do studies show cultivation responses that differ from other Hoya australis subspecies?
What would help: Published comparisons using identified material, with methods, sample sizes and growing conditions reported.
