Leaf architecture in some Amaranthaceae
Feddes Repertorium, 1994AbstractThis paper deals with the leaf architecture of 17 species of the Amaranthaceae. The venation shows mostly pinnate brochidodromy and in some eucamp‐todromy. A new venation pattern — mixed brochidodromy — is reported for the first time. Leaf architectural features help to distinguish all the species investigated and accordingly a key is provided ...

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.

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 ...

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°.

Effects of temperature on leaf hydraulic architecture of tobacco plants
Planta, 2014Modifications in leaf anatomy of tobacco plants induced greater leaf water transport capacity, meeting greater transpirational demands and acclimating to warmer temperatures with a higher vapor pressure deficit. Temperature is one of the most important environmental factors affecting photosynthesis and growth of plants.

Architectural mutation and leaf form, for the palmate series
Journal of Theoretical Biology, 2005Palmate leaf form occurs in both the ferns and angiosperms. The palmate leaf form, and its variants, is present in distantly separated clades within both ferns and angiosperms. There tend not to be intermediate forms which link these palmate leaves to other leaf forms within the taxonomic groups in question. The recurrence of homoplasious leaf forms in

XXI.—On Leaf-Architecture as illuminated by a Study of Pteridophyta
Transactions of the Royal Society of Edinburgh, 1917The expression “architecture” as applied to the leaf was introduced by Prantl in his monograph on the Hymenophyllaceæ. It may be adopted as connoting the sum of the facts of construction of leaves; together with those principles or methods deduced from them, upon which we find the leaf to be built up.

ADAPTIVE LEAF ARCHITECTURE IN EMERGENT AND FLOATING SPARGANIUM
American Journal of Botany, 1972The robust emergent leaves of Sparganium eurycarpum and S. americanum are supported by corner fiber masses and large bundle sheaths, but the thin floating leaves of S. fluctuans and S. minimum
