The biology of myco‐heterotrophic (‘saprophytic’) plants
TL;DR: Most myco-heterotrophs are entirely subterranean for most of their lives and these stages exhibit adaptations consistent with a change in function from organs of absorption to organs of storage, shown by the almost universal loss of root hairs, decrease in surface area.

Phylogenetic Studies in Alismatidae, II: Evolution of Marine Angiosperms (Seagrasses) and Hydrophily
TL;DR: The evolution of hydrophily, unisexuality, and marine habit in angiosperms was explored using estimates of phylogeny obtained by phylogenetic analyses of chloroplast (rbcL) gene sequence data.

Morphological Phylogenetic Analysis of Basal Angiosperms: Comparison and Combination with Molecular Data
James A. Doyle,Peter K. Endress +1 more
TL;DR: Combined analyses of morphological and molecular data generally yield the same topologies as molecular analyses, but morphology overcomes weak molecular evidence in indicating that Chloranthaceae belong just above the basal grade, that monocots are related to Piperales, and that Lauraceae are linked with Hernandiaceae.

The tapetum: its form, function and possible phylogeny in Embryophyta
TL;DR: A hypothetical phylogenesis of the tapetum is proposed on the basis of its morphological appearance and of the nutritional relations with meiocytes/spores, and the evolutionary trends of thetapeta tend towards a more and more intimate and increasingly greater contact with the spores/pollen grains.

Calcium Oxalate Crystals in Monocotyledons: A Review of their Structure and Systematics
TL;DR: New data on the occurrence of three main types of calcium oxalate crystal occur in monocotyledons: raphides, styloids and druses, although intermediates are sometimes recorded.
