muralis)
The photo above shows a close-up of a flower
head of wall-lettuce as seen at the trailhead for the Snipes Mt. Trail # on
the southern slopes of Mt. Adams................October 14, 2005. The flower
heads consist of 5 yellow ray flowers.
The photo above shows the inflorescence (roughly
a panicle) of wall-lettuce.
The photo above shows a typicall lower stem
leaf of wall-lettuce. The pinnatifid leaf has a broad leaf tip which is roughly
triangular in outline with several smaller lower lobes and clasping leaf base.
The central vein tends to be broadly winged below the tip.
