Fig. 40.—Neuropteris heterophylla: seed {Rhabdocarpus) attached to a short pedicel bearing foliage; X2.—From photograph by Kidston (44). Adiantum (figs. 41 and 42). The seeds are borne upon somewhat reduced fronds, occurring singly or in pairs upon pedicels that replace ultimate pinnules. They are rhomboidal in outline and thin lenticu- lar in transverse section, the outer covering (cupule or integument) being laterally dilated and winged, especially below the middle (fig. 43), possibly fibrous or slightly fleshy, and inclosing the less rhom- boidal and nutlet-like structure within; unfortunately no internal structure is preserved. Such seeds have been found in all stages of.
