Two subspecies of P. minor are recognised in the territory encompassed by Flora iberica. A key to their identification is given below:

1	Blades of most leaves conduplicate, rarely flat, those of basal and shoot leaves 0.4-1.6(-2.1) mm wide; branches of the inflorescence flexuous; spikelets ovate-oblong; lemma hairy at the nerves and the base, hairs of the latter usually longer than the width of the lemma; anthers 0.8-1.1 mm	a. Poa minor subsp. minor
-	Blades of most leaves flat, rarely conduplicate, those of basal ones 1.5-2.3 mm wide; branches of the inflorescence straight; spikelets oblong; lemma glabrous or only weakly hairy at the nerves; anthers (1-)1.2-1.7 mm	b. Poa minor subsp. nevadensis
