Species KYLLINGA PUMILA Michx.
PlaceOfPublication Fl. Bor.-Amer. 1:28. 1803.
Synonym Cyperus desicaespitosus Mattf. & Kuekenthal, Pflanzenr. IV20:597. 1936.
Note If Kyllinga is to be included under Cyperus as Kuekenthal has recently done, then Lipocarpha, Ascolepis and Hemicarpha should also be included under Cyperus. Nothing seems to be gained by disturbing the state of these, fairly well-defined elements. The genera should probably be arranged in the following order to show the natural relationships: Cyperus, Kyllinga, Remirea, Ascolepis, Lipocarpha, Hemitarpha.
Description Annual, cespitose, 4-40 cm. high, with leaves (2-3 mm. wide) usually shorter than the slender culms; heads 1-3, confluent, ovoid or cylindric, 4-6 mm. long, compressed; scales membranous, pale green, strongly nerved, the keel prominently toothed; stamens 1 or 2; achene elliptic, 1-1.5 mm. long, pale brown, minutely papillose.
Distribution Widely distributed, often as a 'weed in cultivated ground, from New York to Ohio and southward to Argentina; also in Africa.
