93 ON THE SEXUAL ORGANS OP THE CYCADACEiE. By F. a. W. Miquel. Translated hy W. Thiseltox Dyde, B.A. (Plates XCI. and XCII.) {Concluded.) The suspensors spring from the base of the corpuscles. They are more or less spirally twisted, and descend at first to penetrate into the central cavity of the endosperm, but afterwards they are more or less pushed upwards by the embryo. I have not succeeded in ascer- taining if the suspensors of neighbouring corpuscles can coalesce with one another. It often happens that only one suspensor is well de- veloped, and this produces the embryo. This is shown in Plate XCII. fig. 2 and 4-, where the suspensor proceeds from a corpuscle which appears lacerated, or has been destroyed in making the section. Its remains are still visible at the base of the sterile corpuscles. In fig. 8 however, there are two twisted slispensors, the longest of them bearing the embryo. The suspensors produce lateral branches which terminate in rudimentary embryos in the form of tubercles (fig. 4 and 8). These filamentary bodies represent the structure which the older car- pologists called the flum suspensorium, and which E. Brown called the suspensor. T have proposed for it, in consideration of its function, the name embryoblastanon. Others had applied the ievm proerabryo to it. In no other group of plants is this structure so complex as in Cycads. It is more or less cylindrical in shape, and composed of an aggregation of numerous elongated cells (Plate XCII. fig. 7). The remains of a delicate membrane may be distinguished on its surface I am not able to give any explanation of it, but it may possibly be caused, like the membrane on the surface of the embr^-o, by a slight adhesion to the eudospermic tissue. Such an adhesion might easily take place between the superficial cells of organs which are in contact during the time of their growth. ' The consistence of the filament is firm and solid. It is only at the point of junction with the embryo that it breaks readily. The endosperm, in the axis of which the embryo is tightly packed, is entirely unattached in the cavity which it occupies (Plate XCI. fig. 17 ; Plate XCII. fig. 11-13). At its surface the appearance of the VOL. VII. [APRIL 1, 18G9.] H ;
