Huckleberry flowers blooming today near Whitefish |
An androecium of yellow stamen hidden inside |
The yellow, pollen-forming stamen are hidden in there, tucked away and dry on the inside. (The whorl of stamen is called an androecium, Greek for "man house.") The pollen-catching stigma sticks out just far enough to be a minor obstacle to any insect trying to crawl inside. (The stigma is visible below the greenish flower, in the upper photo.) Previous visits to other huckleberry flowers might have left a little pollen stuck to the insect, and now this pollen rubs off onto the stigma.
Presto! Some of the seeds are fertilized, a berry begins growing, and summer starts taking shape in northwestern Montana.
