Historical development of the present classification of morphological types of stomates
The Botanical Review - Tập 53 - Trang 53-79 - 1987
There is a long-standing confusion between morphologic and ontogenetic classifications of stomates. The earliest scheme, by Vesque (1889) was proposed as basically ontogenetic, but it was soon widely applied to mature leaves. The ontogenetic distinction between haplocheilic and syndetocheilic stomates in gymnosperms, proposed by Florin (1931, 1933) soon suffered a similar fate. Continuing studies ......
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......
