Leaf architecture in Terminalia species
Indian Journal of Forestry, 2001The present investigation on leaf architectural studies of Terminalia species reveals the presence of pinnate camptodromous (brochidodromous) type. Number of secondary veins found to be varies within the species. Intersecondary veins are of composite type except in T. bellirica where it was simple.

Leaf architectural studies in the brassicaceae
The Botanical Magazine Tokyo, 1983The leaf architecture has been studied in 19 genera and 35 species of the Brassicaceae. The major venation pattern is pinnate craspedodromous with the exception ofAlyssum maritimum, Iberis amara, I. umbellata andMalcolmia maritima where it is pinnate-festooned brochidodromous.

Leaf architecture in relation to taxonomy: Ipomoea L.
Feddes Repertorium, 1990AbstractArchitectural features of the leaf in fourteen species of Ipomoea have been studied. The leaves are simple or palmately compound. The major veination pattern conforms either to pinnate brochidodromous or actinodromous type. The leaf shape, apex, base, number of areoles and vein endingy entering the areoles are species specific.

THE TERMINOLOGY OF LEAF ARCHITECTURE
TAXON, 1976SummaryA comparative study of leaf architecture throughout the Angiosperms has been made and six classes of venation patterns are recognised. The terms employed are defined and arranged in a systematic order for convenience of reference. Some new terms have been introduced where greater precision was needed and for little known venation patterns.

Leaf architecture in relation to taxonomy: Meliaceae
Feddes Repertorium, 1992AbstractLeaf architectural features in nine genera and eleven species of the Meliaceae have been studied. The major venation pattern conforms to pinnate camptodromous either with eucamptodromous or brochidodromous and mixed craspedodromous types. The highest degree of vein order is up to 7°.

Leaf-spine architecture for OTN switching
2017 International Conference on Computing, Networking and Communications (ICNC), 2017The application of a leaf-spine switching architecture is considered for Layer 1 circuit switching, such as with OTN ODU-based switching. Simple relationships are derived for the achievable leaf-spine switch capacity and scalability, given the number and capacity of individual leaf and spine switch elements, and bandwidth for leaf-spine interlinks ...

Systematics and Leaf Architecture of the Gunneraceae
The Botanical Review, 2005I. Abstract Cladistic and phenetic analyses of leaf and other morphological characters of Gunnera strongly support monophyly of the genus, with the Saxifragaceae s.str. as the closest sister group. This morphologically based phylogeny provides a more coherent understanding of the evolutionary history of Gunnera than do recent phylogenetic hypotheses ...

A modified terminology for angiosperm leaf architecture
Journal of the Royal Society of New Zealand, 1991Abstract A modified terminology for describing leaf architecture is presented, which incorporates lamina development and gives greater emphasis to the patterns formed by groups of venation elements than to their size. Leaf architecture is described using a hierarchy of venation “elements”, which are grouped into “patterns”, which are located in “zones”
