  • notes   

    An interesting aspect of Scoliopus is that, as in the genus Iris, their flowers are considered to be comprised of three functionally-independent ''pollination units''. Each pollination unit consists of a grouping in like position of:

    • a single large sepal with purple stripes (nectar-guides) leading to a cupped hollow near the sepal base where nectar collects, attracting fungus-gnats and other diptera;
    • a single stamen with a (somewhat downwardly-)extrorse anther...seen here dehiscent & filled with yellow pollen; and
    • a single outwardly curved stylar arm with minutely-papillate stigmatic surface at tip.

    The narrow vertically-ascending petals alternate with the pollination units and have strongly incurved margins. They give rise to the 'adder's tongue' part of the common name, and perhaps serve to encourage pollinators to approach and leave the flowers within the vertical 'wedge' of a single pollination unit.

    Interesting details on the biology of Scolipus can be found in Utrech(1992) and this article by Arthur G. Guppy.
