The relationship between the number of expanded and developing leaves in shoot apices of palms
1994
Dalrymple, N.K. | Fisher, J.B.
The number of developing leaves was compared to the number of mature expanded leaves in the crowns of 42 species of palms representing 28 genera. One species had fewer developing vs. mature leaves. Ten species had approximately the same number of developing and mature leaves. Eighteen species had approximately 1.5 times the number of developing leaves vs. mature leaves. Eleven species had approximately twice as many developing leaves vs. mature leaves. Two species (Copernicia gigas and Gastrococos crispa) had approximately three times the number of developing vs. mature leaves. Additional data from the literature and previously unpublished observations for 19 species are also presented. The 1:1 ratio between the number of developing leaves vs. mature leaves, as hypothesized by earlier authors, was not found in most species of palms.
