Quillaja has been shuffled among tribes and subfamilies of Rosaceae, segregated from it as a separate family, and, most recently, transferred to the Fabales as a separate family. Many anomalous characters have kept it from being settled anywhere permanently. One character never mentioned by systematists, but long known, is the anomalous (for Rosaceae) occurrence of prominent styloid calcium oxalate crystals, reported from the inner bark of stems. We describe in more detail the macropattern of… 

Development of the calcium oxalate crystal macropattern in pomegranate (Punica granatum, Punicaceae).

The development of crystal macropattern in various-aged leaf samples from a living plant and from herbarium specimens is traced using unstained whole mounts, stained leaf samples, and leaf and stem cross sections.

Crystal macropatterns in leaves of Fagaceae and Nothofagaceae: a comparative study

Crystal macropatterns in Fagaceae and Nothofagaceae were examined from cleared herbarium leaves by polarizing microscopy, andTabular presentation of results shows significant although overlapping trends from Fagoideae to Castaneoidesae to Noth ofagaceae, with the latter taxon deviating most from Fagidae.

Crystal diversity and macropatterns in leaves of Oleaceae

Oleaceae leaves surveyed from herbarium specimens of 240 species from 23 genera were rehydrated, bleached, processed into xylol, mounted unstained, and viewed microscopically between crossed

A comparison of leaf crystal macropatterns in the two sister genera Piper and Peperomia (Piperaceae).

This first large-scale study comparing leaf crystal macropatterns of the species-rich sister genera Piper and Peperomia focuses on identifying types of calcium oxalate crystals and their macrop atterns in leaves of both genera.

Calciphytoliths (calcium oxalate crystals) analysis for the identification of decayed tea plants (Camellia sinensis L.)

The first survey of the macropatterns of calciphytoliths in several species of Theaceae and common non-Theaceae plants is provided, providing morphological criteria for distinguishing tea from other plants, specifically the presence of identifiable druses together with calcified trichome bases.

Unique calcium oxalate "duplex" and "concretion" idioblasts in leaves of tribe Naucleeae (Rubiaceae).

Crystal types appear to be systematic features in Naucleeae and Duplex idioblasts (CS and druses) and aggregate concretions are a demonstration that much is yet to be discovered about crystals.

An introduction to cells and their organelles

Parenchyma, chlorenchyma, collenchyma, and sclerenchyma are the four main plant cell types (Figure 1.1, Evert, 2006). Meristematic cells, which occur in shoot and root meristems, are parenchyma

Combined phylogenetic analyses reveal interfamilial relationships and patterns of floral evolution in the eudicot order Fabales

The development of papilionate flowers, and the evolutionary context in which these phenotypes appeared in Leguminosae and Polygalaceae, shows that the morphologies are convergent rather than synapomorphic within Fabales.



Calcium oxalate crystal macropattern development during Prunus virginiana (Rosaceae) leaf growth

The mature crystal macropattern shows druses confined to stem, petiole, and leaf veins, whereas prismatics are localized in stipules, bud scales, and Leaf lamina.

Calcium oxalate crystal types and trends in their distribution patterns in leaves ofPrunus (Rosaceae: Prunoideae)

A trend is evident from mostly mesophyll prismatics in Padus to fewer prismatics and more druses of mixed distribution in Laurocerasus and Cerasus, to mostly druses restricted to veins in Amygdalus and Prunophora.

Distribution of calcium oxalate crystals in the secondary phloem of conifers: a constitutive defense mechanism?

It is concluded that in conifer stems the patterns and frequency of CaOx crystals function as a constitutive defense and in combination with fiber rows, provides an effective barrier against small bark-boring insects.

Systematic wood anatomy of the Rosaceae

The wood anatomical evidence suggests that Cercocarpus be moved to the Maloideae, and that Sorbaria is the most derived representative in the Spiraeoidae/ RosoideAE, and the subdivision of the family and the origin of the MalOideae are discussed.

Systematic and evolutionary implications of rbcL sequence variation in Rosaceae

RbcL-based phylogenies suggest that chromosome numbers are more reliable indicators of some generic alliances than the more commonly used fruit types and that the subfamily Maloideae may have descended from spiraeoid ancestors and the pome is derived from follicular or capsular fruit types.

A survey of tricolpate (eudicot) phylogenetic relationships.

The phylogenetic structure of the tricolpate clade (or eudicots) is presented through a survey of their major subclades, each of which is briefly characterized, and the support for the monophyly of each clade is assessed through citation of the pertinent molecular phylogenetic literature.

Cytotaxonomic Studies in the Tribe Quillajeae (Rosaceae)

A variety of chromosome numbers supports the widely held contention that the tribe Quillajeae is unnatural, and the classical treatment of the family is supported by chromosomal data.

Calcium Oxalate Crystals in Monocotyledons: A Review of their Structure and Systematics

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.
