Leaf architecture of Hamelieae (Rubiaceae)
Feddes Repertorium, 2007AbstractThe tribe Hamelieae sensu Robbrecht comprises seven genera, and is traditionally placed in subfamily Rubioideae. Molecular data, however, places Hamelieae within Cinchonoideae. In this study, leaf architecture characters were examined in order to provide further evidence for the circumscription of Hamelieae and discuss its placement in the ...

Leaf architecture of some acanthaceae
The Botanical Magazine Tokyo, 1984Leaf architectural pattern has been studied in 27 genera and 35 species of the Acanthaceae. The major venation pattern conforms to pinnate camptodromous with eucamptodromous or festooned brochidodromous secondaries, pinnate craspedodromous inAcanthus ilicifolius and acrodromous inLepidagathis trinervis. Intersecondary veins are common.

Genomic architecture of leaf senescence in sorghum (Sorghum bicolor)
Theoretical and Applied Genetics, 2023Leaf senescence in sorghum is primarily controlled by the progression, but not by the onset of senescence. The senescence-delaying haplotypes of 45 key genes accentuated from landraces to improved lines. Leaf senescence is a genetically programmed developmental process and plays a central role for plant survival and crop production by remobilising ...

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 ...
