Description
Acaena is a genus of about 100 species of mainly evergreen, creeping herbaceous perennial plants and subshrubs in the family Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii (A. exigua) and California (A. pinnatifida).[1] The leaves are alternate, 4“15 centimetres (1.6“5.9 in) long, and pinnate or nearly so, with 7“21 leaflets. The flowers are produced in a tight globose [inflorescence] 1“2 centimetres (0.39“0.79 in) in diameter, with no petals. The fruit is also a dense ball of many seeds; in many (but not all) species the seeds bear a barbed arrowhead point, the seedhead forming a burr which attaches itself to animal fur or feathers for distribution
