Oxylobium ellipticum

Oxylobium ellipticum, known as the Common Shaggy-pea is a common small plant in the pea family, found in south-eastern Australia.[1]

Pods with flowers.pods are usually grey brown , rounded ,covered with long silk hairs.

Oxylobium Ellipticum comes under the family FABACEAE.[2]

Description

Oxylobium ellipticum is spreading much branched shrub can grow above 2m tall. Leaves are elliptical to 4 cm long, leathery, brown tomentose beneath, dark green, reticulate veins and margins recurved, apex blunt, often with an abrupt point. It has golden yellow pea flowers in dense terminal clusters. Pods 7–8 mm long, rounded, grey-brown, covered with the long silky hairs. Flowering usually take place between the September and January.[2]

Habitat

Vegetation

This species widespread in montane ecosystems.[2]

Soil

Grows frequently on the skeletal soils and organic brown peat on quartzite sand.[2]

Distribution

Oxylobium ellipticum is endemic to Australia,[2] mostly widespread in Tasmania, Victoria, New South Wales and Queensland.[2]

Research Article

This research is about the molecular phylogeny study between the species like Oxylobium, Gastrolobium, Brachysema, Jansonia, Nemica and podolobium is presented. The study was conducted using the chloroplast DNA and nuclear ribosomal DNA. Oxylobium is shown to be polyphyletic, while Gastrobium is paraphyletic containing within it the genera Branchysema, Jansonia and Nemcia, as well as Oxylobium lineare. Molecular traits such as ovule number, fluroacetate content and different morphological was studied. The molecular analysis were compared to each other. The results support the recent monograph that expands Gastrolobium to include Jansonia, Nemica, Brachysema and Oxylobium. The revision of the leaves Oxylobium and Podolobium occurring exclusively in eastern Australia, while Gastrolobium occurs almost exclusively in south western Australia, with only two species , G. brevipes and G. grandiflorum, occurring outside the Australia.[3]

Golden yellow pea flower in the dense terminal cluster.
