"With respect to the second chief peculiarity, namely the little mass of viscid matter attached to the end of the caudicle, a long series of gradations can be specified, each of plain service to the plant."
"From this simple condition, which differs but little from that of a multitude of common flowers, there are endless gradations, to species in which the pollen-mass terminates in a very short, free caudicle, to others in which the caudicle becomes firmly attached to the viscid matter, with the sterile stigma itself much modified."
"In some orchids there is no caudicle to the pollen-masses, and the grains are merely tied together by fine threads; but as these are not confined to orchids, they need not here be considered; yet I may mention that at the base of the orchidaceous series, in Cypripedium, we can see how the threads were probably first developed."
