Origin of rostellum
Examples from the Web for rostellum
Asa Gray's observations on the rostellum of Gymnadenia are very imperfect, yet worth looking at.
One has a rostellum without hooks, like the tni of the vegetable-feeders, the other has hooks like those of the carnivora.Animal Parasites and Messmates|P. J. Van Beneden
I would give a good deal to know what the rostellum is, of which I have traced so many curious modifications.The Life and Letters of Charles Darwin, Volume II (of II)|Charles Darwin
I want to know whether anything beats in modification the rostellum of Catasetum.
So in other cases, but I have not completely traced (only seen) that going to the rostellum.
