The carpogones are somewhat variable as to their complexity, being much more simple in the lower orders than in the higher. In some cases (Nemalion) the carpo- gone (-B, h, Fig. 77) is thickened below, and elongated above into the trichogyne, which differs from that in Co- leochsete in not being open at the top. 318.
