All the shots below are what I took
recently at the site not so far from
my place, the place bearing a number
of irregular species. There it
occurs a lot of
ringens in a obscure part of it.
There I saw one with a brown flower
for the first time. Almost always
the flower (spathe) is green with
white stripes. Please see it by
enlarging the thumbnail on the 3rd
row, the 1st one from left, and
compare it with the one on 3rd row,
the 1st from right on the same way.
