Pollen grain of Bilbergia flower Featured 20 Apr 1998 Print

Pollen grain of Bilbergia flower

Billbergia pollen. Coloured scanning electron micrograph (SEM) of a pollen grain of Billbergia nutans, a Brazilian house plant known as Queen's Tears or Angel's Tears. It is a member of the pineapple family Bromeliaceae. The pollen grain has a deep furrow running along its length, out of which the pollen tube grows upon germination. The shape and lace-like structure of this pollen grain makes it a unique identifying feature for this plant species. Magnification: x875 at 6x6cm size
