Involucral bracts 2 – 3 (5), largest up to 13 cm long

Spikelet white to pale yellowish brown, often with red dots and green midnerve; spikelet prophyll and glume 1.25 – 2 mm long, often with reddish stripes
Morphology Stem
Stem 15 – 80 cm long, 0.5 – 2 mm across, round or obscurely angled
Note
The name Lipocarpha humboldtiana Nees (1834: 287) has sometimes been considered as a homotypic synonym of Scirpus senegalensis and Hypaelyptum argenteum (e.g., Govaerts et al. 2007), however this is incorrect. Although Humboldt & Bonpland originally identified one of their specimens as Hypaelyptum argenteum, this was a misidentification rectified by Nees who published a new species L. humboldtiana based on this specimen: Humboldt & Bonpland s.n. (holotype P00669499!). Based on a study using molecular and morphological data, L. humboldtiana clearly represents a different species (Bauters et al. 2014). Its correct name when included in the genus Cyperus is Cyperus sellowianus (Kunth) T. Koyama (Bauters et al. 2014). Several studies in which the type specimens and a wide range of other specimens of this species were examined, confirmed that the above-mentioned names are indeed synonymous (Goetghebeur & Van den Borre 1989; Bauters 2011; Bauters et al. 2014).
