Nancy: It also occurs in some orchids. Interesting recent research in this area, e.g. Parallel evolutionary paths to mycoheterotrophy in understorey Ericaceae and Orchidaceae: ecological evidence for mixotrophy in Pyroleae. Tedersoo et al., Oecologia (2007) 151:206–217 Abstract at http://www.ncbi.nlm.nih.gov/pubmed/17089139 There's a lot going on belowground in our forests! >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> [NatureNS] Pyrola info plus plant people question DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; Date: Sun, 30 Jun 2013 06:04:49 -0300 From: nancy dowd <nancypdowd@gmail.com> To: naturens <naturens@chebucto.ns.ca> Precedence: bulk Return-Path: <naturens-mml-owner@chebucto.ns.ca> Original-Recipient: rfc822;"| (cd /csuite/info/Environment/FNSN/MList; /csuite/lib/arch2html)" next message in archive no next message in thread previous message in archive Index of Subjects After reading Ken McKenna's observation of a One-sided Pyrola I was checking the Audubon Wildflower app trying to figure out what a Pyrola was and came across this interesting bit of info under the Bog Wintergreen (P. asarifolia) which also occurs in NS, albeit sparsely: It said Pyrola species can have both leaved (photosynthesizing) and leafless (saprophytic like Indian Pipe) forms of the same plant. They gave the Bog Wintergreen above as an example, sometimes being just a flower stalk above ground and at other times a flower plus leaves. Quite a flexible way to ensure survival under different conditions. Question: Is this common in flowering plants? I can't think of another plant able to feed in both ways- it is usually one or the other. Nancy Sent from my iPhone
