Journal ArticleDOI
Pachycauly, vessel-elements, islands and the evolution of arborescence in 'herbaceous' families.
TL;DR: It is shown that the narrow-pithed leptocauls have wood patterns much like those of the juvenile stages of pachycauls, in contrast to Carlquist's notion of juvenile wood patterns in mature pachyCaul plants.
Journal ArticleDOI
Frost resistance and susceptibility to ice formation during natural hardening in relation to leaf anatomy in three evergreen tree species from New Zealand
G. Neuner,P. Bannister +1 more
TL;DR: Thermal analysis during freezing indicated that all three species became more tolerant of extracellular ice formation in winter and G. littoralis, which was the least frost resistant species, particularly in summer, showed the least degree of hardening.
Journal ArticleDOI
Leaf epidermal micromorphology and its implications in systematics of certain taxa of the fern family Pteridaceae from Northern Pakistan
Syed Nasar Shah,Ali Çelik,Mushtaq Ahmad,Fazal Ullah,Fazal Ullah,Wajid Zaman,Wajid Zaman,Muhammad Zafar,Khafsa Malik,Neelam Rashid,Majid Iqbal,Aamir Sohail,Saraj Bahadur +12 more
TL;DR: F foliar epidermal anatomy provides sufficient information on the taxonomic importance of foliar anatomy which validate its efficacy in species and genera discrimination and is further possible to use leaf micromorphologic data in ferns phylogeny and providing basis for future taxonomic delimitation in other taxa.

Permineralized monocotyledons from the Middle Eocene Princeton chert (Allenby Formation) of British Columbia: Alismataceae
Diane M. Erwin,Ruth A. Stockey +1 more
TL;DR: One small monocotyledon petiole, 1.8 × 1.5 mm wide, has been recovered from the Princeton chert in the Middle Eocene Allenby Formation, British Columbia.

Phylogenetic relationships of theJuglandaceae
TL;DR: A cladistic analysis of molecular data from the chloroplast generbcL suggested a relationship between the higher Hamamelidae and certain families in theRosidae sensuCronquist 1981 (such asRosaceae andRhamnaceae), an outcome which would add credence to the widely accepted view of the polyphyletic nature of theHamamelidae.
