The pinnules bearing the male organs of Lyginodendron occur on the same fronds which bear the ordinary vegetative leaflets, so that Mr. Kidston was able to demonstrate direct organic connection with. Fig. 11.—Calymmatotheca Stangeri. Rachis of the fertile frond, bearing numerous deeply lobed cupules. Drawn by Miss Woodward from Slur's original specimen. the foliage of Lyginodendron Oldlmmmin. The fertile are pedicellate, oval in form, and each of them bears from G to 8 lanceo- late, sharply-pointed microsporangia, described by the author as bilocular. When young the microsporangia are bent inward, with their apices meeting at the center, but at maturity they spread out- ward, appearing like a fringe hanging from the margin of the pin- nule, though in reality attached to its lower surface. In all respects the fructification agrees with Grossotheca (see fig. 8, F) and it is named CroHHotlieca lidningkamii by Mr. Kidston. Though the speci-.
