TLDR
Serial sections of young and old woody stems of Atriplex halimus L. (Chenopodiaceae) were studied with the light microscope and analyzed cinematographically to search for possible connections between the cambia occurring in the primary vascular bundles and the successive c Cambia.Abstract:
Serial sections of young and old woody stems of Atriplex halimus L. (Chenopodiaceae) were studied with the light microscope and analyzed cinematographically to search for possible connections between the cambia occurring in the primary vascular bundles and the successive cambia. The first extrafascicular cambia initiated from cambial bands which develop continuous with the still active intrafascicular cambia of the primary vascular bundles. The additional successive cambia also appear to start developing continuous with preceding still active cambia. The primary vascular bundles and the vascular strands of the secondary increments are all interconnected.read more

Symplasmic networks in secondary vascular tissues: parenchyma distribution and activity supporting long-distance transport
TL;DR: This review highlights key historical work as well as current research on the structure and function of parenchyma in secondary vascular tissue in the hopes of spurring renewed interest in this area, which has important implications for whole-plant transport processes and resource partitioning.

Successive cambia revisited: ontogeny, histology, diversity, and functional significance
TL;DR: The varied appearances of each of these tissues in genera that have successive cambia is discussed, and themes that particular genera represent are examined: storage and retrieval; promotion of mechanical strength and longevity of vascular tissues; and modes of lianoid structure.

Atriplex halimus L.: Its biology and uses
TL;DR: Its deep root system decreases soil erosion in arid zones, due to stabilisation of the soil, and its protein-rich shoot material makes it an important fodder species for livestock, however, its low energy value means that it should be supplemented with carbohydrate-rich material, such as cereal straw.

TL;DR: Successive cambia are an ecologically important characteristic, which seems strongly related with water-limited environments, and it is observed that 84.9% of the woody shrub and tree species with concentric internal phloem occurred in either dry or saline environments strengthening the hypothesis that successive c Cambia provide the necessary advantages for survival in harsh environmental conditions.

Comparative anatomy of the vegetative organs of the phanerogams and ferns
TL;DR: De Bary's “Vergleichende Anatomic der Vegetations-organe der Phanerogamen und Farne” (published in 1877) proved to be a masterpiece of industrious research, accurate treatment of facts, and critical sifting of details.

The ontogeny of the vascular cambium in the stem of seed plants
TL;DR: A striking characteristic of the vascular cambium is its plasticity, it may arise in any position in any tissue except the epidermis, and a number of these possibilities may be combined in one plant either simultaneously or at different stages of growth.

The Mucilage Cells of Opuntia ficus-indica (L.) Mill.-Development, Ultrastructure, and Mucilage Secretion

TL;DR: Cytochemical tests of polysaccharides confirmed that only the Golgi bodies are involved in mucilage secretion and also suggest that the mucilage passes through the plasmalemma by reverse pinocytosis.
