Morphology and development of leaf papillae in Sematophyllaceae
The Bryologist, 2010Abstract Micro-morphological studies on mosses are not common, but have the potential to illuminate the nature of taxonomic characters. Data on the structure and development of leaf cell papillae in the Sematophyllaceae obtained using light and scanning electron microscopy techniques are presented to assess developmental similarity and congruence with ...

Soybean Leaf Morphology and Defoliation Tolerance
Agronomy Journal, 1998AbstractPlant tolerance to pest injury is an ideal component of integrated pest management (IPM) programs, because it places no selection pressure on pest populations, but tolerance is little understood and its use in pest management is limited. In field experiments in 1994, 1995, and 1996, we characterized tolerance to defoliation in ‘Clark’ soybean ...

Parallel evolution of leaf morphology in gnetophytes
Organisms Diversity & Evolution, 2015In the present paper, an ephedroid macrofossil species from the Early Cretaceous Yixian Formation of western Liaoning of China is described as new to science: Ephedra multinervia Yang et Lin, sp. nov. This species has typical ephedroid morphology, e.g.

Leaf morphology of the imbricate-leaved Podocarpaceae
Australian Systematic Botany, 1989The leaf arrangement and cuticular micromorphology of living species of the Podocarpaceae with an imbricate leaf arrangement demonstrates that generic determination is possible on this basis alone. This is of particular interest in Dacrydium, Halocarpus, Lepidothamnus and Lagarostrobos, which until recently were considered to be monogeneric.

Ontogeny of Leaf Morphology and Anatomy
1985Because of their role in intercepting and absorbing radiant energy, and transforming it to energy of organic substances through the complex process of photosynthesis, leaves are the most important organs for plant production, and hence for agriculture.

The Problem of Leaf Morphology and Evolution in the Monocotyledons
The Quarterly Review of Biology, 1973A review of the previous literature on the morphology and evolution of monocotyledonous leaves reveals a number of interpretive controversies and contradictions. The phyllode theory, which has been the prevailing interpretation of the origin and evolution of monocotyledonous leaves, is evaluated and is shown to have been biased by a preoccupation with ...

Leaf Morphology of Calandrinia and Montiopsis (Portulacaceae)
Annals of the Missouri Botanical Garden, 1993Calandrinia sect. Calandrinia, C. sect. Monocosmia, and some species of C. sect. Acaules share identical leaf blade and petiolar morphology, fimbrial veins, predominantly brachytetracytic and staurocytic stomata surrounded by a cycle of subsidiary-like cells, and unicellular ribbed trichomes or papillar trichomes. Other species of C. sect. Acaules have
