Exocarpos humifusus, also known as mountain native-cherry, is a small shrub member of the family Santalaceae, all of which are hemiparasites. Exocarpos humifusus is a dwarfish and sprawling shrub with woody stems, and small dry fruits that grow atop a fleshy red stalk, hence the common name of native-cherry.[1]
Description
Exocarpos humifusus is a rigid, woody dwarf shrub with branches prostrate and spreading over the ground and rocks.[2] The stems are dark yellow-green tinged with red, and are ribbed with rounded edges.[2] The leaves are triangular and scale shaped, about 0.5 mm (0.020 in) long, arranged alternately along the stem.[2][3] The flowers are generally 4 parted, approximately 2.5 mm (0.098 in) in diameter and grow in bunches of 2-3 on a short stalk at the end of a stem.[2] The fruit is a small greenish-black drupe or nut 3–4 mm (0.12–0.16 in) in length, that grows atop a fleshy receptacle.[2][4] When mature the receptacle of the fruit is dark red fleshy, juicy and edible, attracting animals as distributors.[4]
Habitat and distribution
Exocarpos humifusus is endemic to Tasmania. It grows abundantly above 1,000 m (3,300 ft) and on lower elevation mountains in the south-west, in sub-alpine and alpine areas. It is found growing over the surfaces of rocks on mountain plateaus and summits throughout Tasmania.[1] It is widespread among the plant communities of alpine heath and fjaeldmark.[5]
