Glycine clandestina
Twining Glycene
Twining Glycene
Common name: Twining Glycene
Conservation status: Least concern
Etymology:
Glycine…. from Greek glykys, sweet, possibly referring to the sweetness of the tubers in the genus Apios, which was previously included in Glycine
Clandestina…. from Latin clandestinus, secret or hidden, perhaps referring to the scrambling and inconspicuous growth habit
Flowers:
The flowers, which appear in winter and spring, are usually mauve to pale pink and white
They are the typical “pea” shape consisting of 4 petals; the “standard”, the “keel” and two “wings”
Racemes 4–18-flowered, 1–3.5 times as long as leaves
Calyx finely pubescent or strigose, 3 lower teeth from two-thirds to equalling the tube
Standard 5–10 mm long, ± mauve to rose-purple or white
Fruit:
The flowers are followed by elongated pods up to 40 mm long.
Pod straight, 1.2–5.3 cm long, 2.5–4 mm wide, without purple flecks, sparsely hairy to glabrous
Seeds 4–12
Leaves:
The leaves are arranged alternately on the stems and are 3-foliolate with the middle leaflet usually longer in length than the other two
The leaflets are linear to lanceolate in shape and up to 40mm long by 10mm wide
Leaves palmately 3-foliolate, dimorphic; leaflets of upper leaves linear to ± narrow-elliptic or oblong-lanceolate, 1–8 cm long
2–10 mm wide, apex obtuse or acute; leaflets of lower leaves (and often in the subalpine plants) oblanceolate to broad-obovate or ± circular, 0.5–3.0 cm long
2–8 mm wide; upper surface sparsely hairy to ± glabrous; lower surface with appressed or spreading hairs
Stipels absent on median petiolule
The leaflet shape and pubescence are extremely variable; however, it is not possible to formally separate these entities due to the number of intermediates between them.
Stem & branches:
Twiner, stems non-stoloniferous; hairy with retrorse, white, grey or dark rusty, soft hairs
Roots:
Habit:
A twining plant in the bean family
It is usually a wiry, twining plant whose thin stems twist around the stems of other plants
It is inconspicuous and it is often not noticed until the flowers appear
It is not especially vigorous and does not overwhelm other plants
Habitat:
Widespread from coast to subalpine situations
Distribution:
NSW subdivisions: NC, CC, SC, NT, CT, ST, NWS, CWS, SWS, NWP, SWP, NFWP
Other Australian states: Qld Vic. Tas. S.A.
Additional notes:
Cultivation
Twining Glycine is rarely cultivated but, given its wide natural range, it should be adaptable to most soils and aspects
The plant has limited horticultural potential and is rarely available even from specialist native plant nurseries
Propagation is easy from seed following pre-treatment to break the physical dormancy provided by the impervious seed coat
Pre-treatment can be carried out by abrasion or by the use of boiling water
Cuttings could be expected to strike well using firm, current season’s growth
