As discussed in Chapter 4, the first sporophytic leaves, having only a single,
generally unbranched vein and lacking a leaf gap, are called lycophylls (
essentially equivalent to microphylls ); lycophylls also possess an intercalary
meristem (at ...

... above the geometrical distance between leaf tips (figure 3. 1 5). This

While the first leaf-gap is closing and the second is forming, an internal
endodermis appears in the pith. It is at first incomplete (4 a), but soon becomes a
complete tube (46). The external and internal endodermis become continuous as
the ...

Almost as much importance has been attached to the absence of a leaf-gap in
the Lycopsida as to their microphylly. Dr. Jeffrey has recently asserted that the

trace ...

In this example, lateral traces as well as the main trace depart from a leaf gap
and enter a petiole. In some dictyostelic ferns, such as Bolbitis diversifolia,
figured by Ogura (1972, p. 56), leaf traces mostly depart from the lateral margins
of the ...

Distal to the departure of a particular leaf from the stem, the two meristeles which
border the leaf gap fuse and thus close the gap. Distal to the level where a
particular leaf gap closes, the leaf gap for the next leaf in the orthostichy opens. II.
