Morphology Culms
Culms moderately to densely tufted, 18 - 32 cm x 0.7 - 0.9 mm, terete to ± trigonous, smooth, green, densely covered at base by mid- to dark brown leaf sheath remains
Morphology General Habit
Shortly rhizomatous perennial
Morphology Leaves
Leaf blade narrowly linear, 6 - 29 cm x 0.4 - 0.7 mm, very gradually tapering to an acute apex, flat in cross- section, margins smooth, green; sheath 2.5 - 3.5 cm long, mid-brown

Stamens 3; anthers 1.2 mm long
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigmas 3
Morphology Reproductive morphology Fruits
Nutlets obovate, trigonous with convex sides, 0.7 - 0.8 x 0.4 mm, maturing dark brown, very minutely papillose.
Morphology Reproductive morphology Inflorescences
Inflorescence lax capitate, 2.5 - 5 x 4 - 5.5 cm
Morphology Reproductive morphology Inflorescences Bracts
Involucral bracts 2 - 3, leaf-like, the longest 6 - 12 cm long, margins smooth
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes 18 - 44 per spikelet, ovate-lanceolate, 2.4 - 2.7 x 1 - 1.6 mm, ± acute, sides membranous, 2 - 3- nerved on each side, mid-reddish brown, keel green to pale brown
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets 14 - 18 per inflorescence, linear, (1 -) 1.8 - 2.5 cm x 1.8 - 2.4 mm, flattened, reddish-brown, rachilla straight
Note
Name refers to the distinctly long spikelets possessed by this species. Cyperus longispicula is related to C. kirkii, differing by its larger inflorescence and longer spikelets. Its relationship to C. kirkii places it within sect Amabiles C. B. Clarke, a natural grouping of taxa characterised by narrow spikelets and small reddish to brown glumes. This was accepted by Kiukenthal (1936). Interestingly Haines & Lye (1983) include this section and sect. Platystachyi together in subgen. Xerocyperus Lye, despite the taxa being morphologically distinct. They do, however, say that subgen. Xerocyperus is heterogeneous and could be split into 3 - 4 subgenera. We favour the sectional classification adopted by Kiukenthal, as we feel that subgeneric recognition places too much importance on what are relatively small groups of taxa.
