Isopogon

Isopogon is a genus of 35 species of mainly low-growing and prostrate perennial in the family Proteaceae endemic to Australia. They are found throughout Australia, though Western Australia has the greatest variety with 27 of the 35 species found there. They are popularly known as drumsticks due to the shape of their inflorescences. [more]

Stamens in 2 whorls, inserted at base of perianth; filament linear to subfiliform; anther basifixed or dorsifixed, erect. Ovary subclavate, with many ovules. Style filiform; stigma 3-lobed. Fruit a capsule, oblong-clavate, 3-valved. Seeds black, ovoid-oblong, small.[4] [more]
