(A) Scolex containing four round suckers and a
rostellum armed with two alternating crowns of hooks (400 [micro]m).
It has scolex with hooks and suckers and an armed
rostellum. The body is termed as proglottids arranged in a linear series.
The pollen of the vanilla flower is covered by an anther and the stigma is protected by a covering shield, the
rostellum. Before the pollen can be placed on the pistil, the
rostellum must be lifted.
"A membrane called the
rostellum separates the flower's anther from the stigma making self-pollination impossible," explains the longtime curer and exporter.
The specimen possessed a rudimentary
rostellum, a distinguishing characteristic that, according to Rodgers (1941), separated this species from two similar North American species, Anonchotaenia globata and A.
