Habit Foliage Flowers
Miner's lettuce (Claytonia perfoliata) foliage has two distinct
forms.
Initially, the plants form a rosette with leaves that look like a snake's
head. I used the same analogy to describe the foliage of Calandrinia
ciliata, however, the 'snake head' of this plant is much wider than
that of C. ciliata.
The shape of the leaf tip is variable in width, but petioles are always
very long. Foliage is glabrous (without hairs) with entire margins.
Veins are only visible upon close examination.
Later foliage develops that completely encircles the stem. These
are actually two leaves which have fused at their bases. This type
of foliage is generically called 'perfoliate', which is how the species name
is derived.
The images above and below show a cauline leaf (leaf on the stem) from underneath
and from above.
