I note though that most explanations focus on why a plant would want to
get to the canopy area, as opposed to why it would elect to GET RID of
the underlying stem. Is this a competitive advantage that
allows these plants to compete equally against others in similar niche
(well, you may have a stable water supply, but you gotta spend energy
maintaining it, whereas ther is a chance I may end up in an inhospitable
spot, but in the meantime, I can recycle old tissue matter into growing
at the tips, and growing faster than you)...
You may well have it. It could be similar to a rhizomatous habit;
rhizomatous plants grow at the shoot end, and die off at the "back" end,
gradually migrating in the direction of growth. Rhizomatous plants put out
roots all along their underground stems (rhizomes). Your secondary
hemiepiphytes do the same all along their climbing stems. The question is,
are there terrestrial rhizomatous plants in the same genera as secondary
epiphytes? This could suggest an evolutionary relationship between the two
habits.
