Plants in the genus Acrotriche are shrubs with hairy branchlets, leaves with more or less parallel veins and small flowers with 5 sepals and petals joined at the base to form a bell-shaped to cylindrical tube with hairs and stamens in the throat.

Description
editPlants in the genus Acrotriche are shrubs with branchlets with fine, soft or downy hairs, and leaves with short petioles and more or less parallel veins and a lighter shade of green on the lower surface. The flowers are small and bisexual, sessile or on a short spike in leaf axils with a bract and 2 bracteoles below the 5 sepals. The bracts, bracteoles and sepals are egg-shaped to almost round. The 5 petals are joined at the base to form a bell-shaped or cylindrical tube with 5 tufts of hair in the throat and the tube filled with nectar. The petal lobes are triangular with the anthers bent backwards between the lobes. The ovary is more or less spherical with 2 to 7 locules, each locule with one ovule. The fruit is a drupe with a pulpy mesocarp and a hard endocarp.[2][3][4][5]
Taxonomy
editThe genus Acrotriche was first formally described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[6][7] The genus name (Acrotriche) means "hair at the end".[8]
