One poet's explanation of a cinquain

Plucked from inside one of my poetry books (while searching for a poem with April in the title) was a stark white sheet of paper with the top half defining the subject of the cinquain poetry pattern.
Since former Arkansas Poet Laureate Verna Lee Hinegardner loves for anyone to reprint her poems, I take the liberty to transcribe her definition and her poems.

She writes: "If I asked you what a Cinquain is and you said it was a 5 line poem, you would be correct. Or if you said it was a poem with a syllable count of 2,4,6,8,2, you would be correct.
But an Adelaide Crapsy Cinquain is a bit different. An Adelaide Crapsy Cinquain is written in strict Iambic Meter. The beat is "Unstressed - stressed" and this beat demands a strong accent at the end of each line. It can be either light or serious--but generally the last line has a bit of a twist. It must have a title. The title should not be one of the lines, and should be something that does not tell the outcome. Twenty-two syllables plus a title. Leave off all sham, all vanity."

Here is one of Adelaide Crapsy's (sometimes spelled Crapsey) cinquain:

TRIAD

There be
three silent things:
the falling snow ... the hour
before the dawn ... the mouth of one
just dead.

Here are two of Poet Laureate Hinegardner's prize-winning Cinquains:

THE AWAKENING

Useless
as one limp glove,
the widow twists her ring
until she learns she has to stir
the stew.
~~

EMPTY ARMS

Old folks
are vacant barns
with empty lean-to arms
that reach to guard those precious things
long gone.
