Common name: Bulbous Poa
Poa bulbosa L. APNI*
Description: Tufted bulbous-based perennials to c. 50 cm tall, the bulbous portions elongate-conical or pear-shaped, the shoots intravaginal. Culms erect or geniculate-ascending or spreading, slender, smooth, unbranched, 2–4-noded.
Sheaths glabrous and smooth; ligule membranous, acute to acuminate, 2–8 mm long; blade narrow, flat or folded or the margins inrolled, linear, 1–10 cm long, mostly 1–2.5 mm wide, glabrous, ± smooth, thin.
Inflorescence usually dense, ovate or oblong, c. 2–6 cm long, branches ± erect. Spikelets ovate to broadly oblong, 3–5 mm long, 3–6-flowered, variegated. Glumes keeled, acute to finely acuminate, 1–3-nerved. Lemmas acute, obscurely 5-nerved, strongly keeled; palea mostly scabrous. At times part of the spikelet above the glumes is replaced by a miniature vegetative shoot, which, under favourable conditions, may fall, take root and serve as a vegetative propagule.
Flowering: Flowers in spring.
Distribution and occurrence: Grows in open grassland and disturbed ground. Native of Mediteranean region and Europe.
