(From Lankester's Treatise on Zoology, part iv.) and of the female (vaginal) ducts, there is a distinct uterine opening at the opposite end of the body (b).

It is best seen in very young Vaginal cavity B children and represents the vasa effer entia in the male.
The bulbs of the vestibule are two masses of erectile tissue situated one on each side of the vaginal orifice: above they are continued up to the clitoris; they represent the bulb and the corpus spongiosum of the male, split into two, and the fact that they are so divided accounts for the urethra failing to be enclosed in the clitoris as it is in the penis.
The laminar portion of a leaf is occasionally articulated with the petiole, as in the orange, and a joint at times exists between the vaginal or stipulary portion and the petiole.
