#1787 - Cenchrus macrourus African Feather Grass
AKA Pennisetum macrourum. The genus’ name is derived from the Greek for Millet, and macrourus’ means ‘longtailed’.
A South African perennial now also growing as a weed in Australia and New Zealand. It may have arrived in imported seed, or escaped from gardens. It grows up to 2m tall, but despite the long seedhead mostly spreads by rhizomes. On the other hand, the seeds are barbed and easily lodge in animal fur and clothing.Thick infestations are favoured by feral rabbits and cats, but are unpalatable to livestock even when little else is available.
Other Cenchrus species grow in Asia, Africa, Australia, the Americas, and various oceanic islands. Common names include buffelgrasses, sandburs, and sand spur, since this species isn’t the only one with barbed seeds.
