A 300-million-year record of atmospheric carbon dioxide from fossil plant cuticles
TL;DR: A continuous 300-Myr record of stomatal abundance from Fossil leaves of four genera of plants that are closely related to the present-day Ginkgo tree is presented, supporting the role of water vapour, methane and CO2 in greenhouse climate warming over the past 300 Myr.
Journal ArticleDOI
Volatile leaf oil analysis in chemosystematic studies of North American conifers
TL;DR: The chemosystematic results based on leaf oil analysis of northern North American conifers of the families Pinaceae and Cupressaceae are summarized and discussed in relation to known botanical relationships and other chemosSystematic approaches.
Journal ArticleDOI
Variation in the organization of the stomatal complex in the leaf epidermis of monocotyledons and its bearing on their phylogeny
TL;DR: Using macerated pieces of epidermal tissue from living plants and herbarium specimens, stomatal complexes of 192 species belonging to 49 families of monocotyledons were studied, suggesting that the type with many subsidiaries is the most primitive and the other 2 types have been derived from it independently by reduction of the number of subsidiary cells.
Journal ArticleDOI
Comparative Chloroplast Genomics Reveals the Evolution of Pinaceae Genera and Subfamilies
TL;DR: The phylogenetic analyses reveal that Cedrus is clustered with Abies–Keteleeria rather than the basal-most genus of Pinaceae and that Cathaya is closer to Pinus than to Picea or Larix–Pseudotsuga, and views on subfamilial classifications differ from previous studies in terms of the rank of Cedrus and with recognition of more than two subfamilies.
Journal ArticleDOI
A new classification of the ontogenetic types of stomata
TL;DR: The gap between morphological and ontogenetical classifications has been bridged and any other new type can be included and all the possibilities for the introduction of supplementary data are left open.
