“…Consequently, only the evolution with the MK1 model is presented in Figures . Inferred evolutions of stele type and stele diameter were detailed in the previous study (Dubuisson et al ., ) and are reported in Figure . The evolution of blade length and root system is shown in Figure .…”

“…Dubuisson et al . () showed that climbing taxa outside the HE clade and all taxa belonging to the HE clade have a heterogeneous cortex, which appears to be significantly related to a colonial strategy and is conserved in colonial epiphytes. The present study infers the common ancestor of the HE clade as an individual terrestrial.…”

“…In accordance with previous hypotheses (Dubuisson et al ., ), we particularly propose here to test correlations between morphological and anatomical regression and epiphytism and between metaxylem diameter and climbing habit of (hemi)‐epiphytes. Morphological and anatomical regression is represented by small to dwarf size (leaves shorter than 6 cm), regressed root system, small stele (< 150 μm) and subcollateral and collateral stele types.…”

“…The present study is analogous to and derived from a previous study (Dubuisson et al ., ). The aims of this study are to infer the evolution of the ecology and related morphological and anatomical changes in trichomanoids, relying on an expanded molecular phylogenetic analysis representing morphological, ecological and geographical variability in the lineage, and on adequate statistical tests.…”

The few studies on the evolution of epiphytism in ferns have mostly focused on xerophytic and humus‐collecting strategies, neglecting hygrophytes that are abundant in rainforests, such as the trichomanoids (Hymenophyllaceae). Using a phylogenetic approach, we studied the acquisition of epiphytism in this lineage, with the aim of identifying ecological anatomical adaptations and verifying the regressive epiphytic ‘bryophyte‐like’ strategy previously suggested for the group. Inferred evolution of anatomy and morphology, regression and ecology (more particularly colonial epiphytism) were analysed and compared using a maximum likelihood approach. Regressive evolution of anatomy and morphology is revealed in the three clades of colonial epiphytes, probably linked to the selection of water acquisition by blades rather than by regressed roots. However, the ‘bryophyte‐like’ strategy is restricted to some taxa (especially Didymoglossum). Furthermore, a relationship is revealed between large metaxylem and climbing habit. Diversification of colonial epiphytes (and some individual epiphytes) and hemi‐epiphytism would have occurred in the upper Cretaceous and Tertiary, in accordance with the timing of diversification of modern ferns and the evolution of epiphytism in other fern families in the first angiosperm‐dominated forests. This was here performed by selecting hygrophilous strategies that are unique in vascular plants. © 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 173, 573–593.

Ecophysiological differentiation between life stages in filmy ferns (Hymenophyllaceae)

Desiccation tolerance was a key trait that allowed plants to colonize land. However, little is known about the transition from desiccation tolerant non-vascular plants to desiccation sensitive vascular ones. Filmy ferns (Hymenophyllaceae) represent a useful system to investigate how water-stress strategies differ between non-vascular and vascular stages within a single organism because they have vascularized sporophytes and nonvascular 1 .
