Models of Cannabis Taxonomy, Cultural Bias, and Conflicts between Scientific and Vernacular Names
The Botanical Review - Tập 83 - Trang 327-381 - 2017
Debates over Cannabis sativa L. and C. indica Lam. center on their taxonomic circumscription and rank. This perennial puzzle has been compounded by the viral spread of a vernacular nomenclature, “Sativa” and “Indica,” which does not correlate with C. sativa and C. indica. Ambiguities also envelop the epithets of wild-type Cannabis: the spontanea versus ruderalis debate (i.e., vernacular “Ruderalis......
Compression wood in conifers as a morphogenetic phenomenon
The Botanical Review - Tập 20 Số 9 - Trang 551-560 - 1954
Although much has been done with compression wood, its basic causes have only recently been investigated. It seems quite clear that compression wood is formed indirectly as a counteractant to forces tending to deform a tree in any way. It seems equally clear that compression wood is actually under great compression and actually tends to straighten the tree or otherwise overcome the deformation, be......
Apomorphy-based definition also pinpoints a node, and PhyloCode names prevent effective communication
The Botanical Review - Tập 69 - Trang 44-58 - 2003
Acceptable methods of defining taxon (or clade) names in the draft PhyloCode, or so-called phylogenetic nomenclature, are “node based,” “stem based,” and “apomorphy based.” All of them define a clade name by pinpointing a node; whereas node-based and stem-based definitions require two or more taxon “specifiers” to define names, an apomorphy-based definition requires two specifiers of different typ......
Guttation: Mechanism, Momentum and Modulation
The Botanical Review - - 2016
Guttation is one of several visible physiological events of plant kingdom. The mechanism of this phenomenon is however, obscure and embedded deep into mysteries despite its vital significance for the plants and people. In this paper attempts have been made, in the light of recent discoveries, and new and novel findings, to review the past and present works reflecting on an integrated view of the m......
Reversion of flowering
The Botanical Review - Tập 56 - Trang 162-189 - 1990
Reversion from floral to vegetative growth is under environmental control in many plant species. However the factors regulating floral reversion, and the events at the shoot apex that take place when it occurs, have received less attention than those associated with the transition to flowering. Reversions may be categorized as flower reversion, in which the flower meristem resumes leaf production,......
