Re: [Aroid-l] Holes

From: Jason Hernandez <jason.hernandez74 at yahoo.com> on 2012.02.27 at 17:11:39(22632) The difficulty I have with the "tropical storms" idea is that some fenestrated Monstera spp. occur in regions not subject to tropical storms, e.g. the premontane cloud forest of the Pacific coast of Ecuador. I will let growers address the matter of whether scandent Monstera with fenestrated leaves are any easier to pull away from the substrate than, say, scandent Philodendron with entire leaves. I am not sure what you mean by "created." We may suppose that the primeval leaf was linear, like the branches of Equisetum or the needles of a conifer (think also of Lycopodium and Araucaria), and that the next evolutionary step was a broadening, so as to capture more sun. All the variations in leaves we see are developments in response to the requirements of different niches. The juvenile-stage leaves of a Monstera probably approximate the ancestral leaves, in parallel with the way various organisms' embryonic development hints at their evolutionary stages.

If the plants have a weak root system and coulds easily bee uprooted then I think this is the likely reason. But now another question arises; Were they created like this or were the leaves full and somewhere along they line developed holes in them to adapt? ________________________________ From:aroid-l-bounces@www.gizmoworks.com [mailto: href="mailto:aroid-l-bounces@www.gizmoworks.com">aroid-l-bounces@www.gizmoworks.com] On Behalf Of John Sent: Friday, February 24, 2012 7:55 PM To: ' Discussion of aroids ' Subject: [Aroid-l] Holes ? Can anyone say what might be the biological purpose of leaves with holes in them?? A typical example would be Monstera deliciosa. ?
