Cyperus holstii

Cyperus holstii is a species of sedge that is native to central Africa, including the Democratic Republic of the Congo, Tanzania, and Kenya.[2]

The species was first formally described by the botanist Georg Kükenthal in 1925.[2]

Ecology and Distribution

In Tropical Africa, the biology of Cyperus holstii is a perennial herb to 1, 15 m tall, with stolons c. (2 mm) and is covered by loose scales; culms few (45-67 cm long, 3,5-6 mm), trigonous; leaves (1-31 to 50 cm long); sheath is pale brown, and is sometimes pale reddish-brown (6-12 cm long); blade flat (16-38 cm long, 5,5-10 mm).[3]

Cyperus holstii grows on seasonally wet grassland; alongside pools; swamps; 0-250 m alt. Very similar to C. longus from which it differs by its longer peduncles (10-30 cm vs. 0,5-10 cm), more numerous (6-9 vs. 2-5) and larger involucral bracts (15-40x0, 4-0,8 cm vs. 6-28x0, 2-0,5 cm).
