FIGURE 1. Morphological variability in habit and awn within Aristida tenuissima. A-I: large plants with one-awned and three-awned spikelets on the same individual A large habit B spikelet with three unequal awns C spikelet with a single awn D lower glume, ventral view E upper glume, ventral view F floret G lower part of the floret and callus, lateral view H lemma surface with prickle hairs I lower part of the floret and callus, ventral view. J-L: medium-sized plants with one-awned spikelets J habit K spikelet with a single awn L ligule. M-O: small-sized plants with one-awned spikelets M habit enlarged N habit life size O spikelet with a single awn. P: spikelet with 3 equal awns. Scale bar: A, J, M = 4 cm; L = 1.3 mm; D,E = 2 mm; B, C, F, K, O, P = 3.3 mm; G, I = 1.1 mm; H = 0.5 mm; N = 1 cm.
