Abstrakt | We took under the microscope the structure of a stapeliad flower (the milkweed family-Asclepiadaceae). The reproductive organs form a structure called a gynostegium, with a single or double set of coronal appendages. The filaments form a staminal column with five staminal "locks" or slots. Pollen merges into waxy pollinia, pairs of which are connected by translators into separate structures-the pollinaria. A stapeliad pollinium has an elongated surface structure called a pollinium key. Visiting insects, mostly flies, tear away a whole pollinarium and insert it into the staminal lock of another flower: the key slides up the lock, approaches the stigma, and the flower is pollinated. | |
