Base Species or Cultivar:
'Southern Star' was identified as a unique hybrid, as distinct from 'Macrolobium' - which it had been identified as previously, due to the leaf shape, width of the leaf in comparison to the length and the pinnatifid ovate leaf. A visual comparison of this form and a published example of macrolobium has confirmed it to be unique.
This cultivar also has the ability to reproduce selfed seedlings which share the same features as the parent plant.
'Southern Star' represents an amalgamation of the Southern Cross constellation and alludes to the shooting star like shape of the leaf. This name was chosen by Mandar Nelson and ratified through polling of the Aroid Society of Australia (ASA).
Ovate pinnatifid with a prominent long acuminate anterior lobe. Acuminate lobe should extend to at least twice the height of the pinnatifid leaf base. Leaf is medium to dark green, coriaceous and stiff. Four sets of basal veins should be easily identifiable, with a variable number of lateral veins visible, 5-7 typically displayed. Sinus is naked and usually v-shaped to slightly spathulate. Examples exist of this cultivar with a wider sinus.
Bloom and Fruit:
Spathe acuminate and light green with yellow overtones, spadix reflexed and green to violet green. This plant is known to be able to self pollinate and does produce a fine cream to yellow pollen.
The ovate pinnatifid leaf is unique to this cultivar due to the presence of a conspicuously long acuminate anterior lobe which should comprise at least twice the width of the pinnatifid base.
It can be compare to the species pedatoradiatum or pedatum, wherein the pinnatifid leaf is present, but 'Southern Star' has less prominent pinnatifid margins when compared to either species. Another comparison with 'Macrolobium' will show the lack of the prominent acuminate lobe.
Several examples of this cultivar can currently be found in Australia and Asia, with several of the Asian variants typically displaying a slightly wider to open or flat sinus.
