Thread like Opposite Oppositely Attached directly by the base, not stalked. Flower rests directly on the stem Bent or curved downward or backward Flower spikes so close together they appear to be like a head. Forming a rounded head Arranged around an axis; not opposite as in distichous Spreading like fingers in a hand and therefore there is no conspicuous main central spike. The main axis would be very short. Surfaced with small scurfy scales (trichomes) Smooth, glossy, i.e. without hairs or scales Closely and flatly pressed against Spindle shaped Frosty; covered with fine scales, hairs, dust, bloom, or the like, so as to give the appearance of frost. Sword-shaped Twisted to one side. Bent, as a knee. Terminating abruptly in a little point which is not particularly stiff.
