The development of the seed coat ofSimmondsia, whose relationships are extremely problematic, is documented, and its structure is compared to those of putatively related families Euphorbiaceae and Buxaceae. InSimmondsia, the young seed coat is composed of (1) the palisadal exotesta, (2) the thick aerenchymatous mesotesta which is further differentiated into the outer and the inner tissue of mesotesta, and the undifferentiated (3) endotesta and (4) tegmen. At maturity, only the palisadal… 
Oldest record of Trimeniaceae from the Early Cretaceous of northern Japan
TLDR
The fossil seed provides the first evidence that Trimeniaceae was distributed in a midlatitude location of the Northern Hemisphere during the Early Cretaceous, when angiosperms radiated extensively, supporting a hypothesis that the extant austral distribution is relict.
A taxonomic backbone for the global synthesis of species diversity in the angiosperm order Caryophyllales
TLDR
A taxonomic backbone at the genus level is provided that reflects the current state of knowledge and accepts 749 genera for the Caryophyllales, a major lineage of flowering plants with approximately 12500 species in 39 families.
Increase the economic value of the jojoba (Simmondsia chinensis) yield using evaluation of distinctive clones grown under the Egyptian environmental conditions.
TLDR
It is concluded that jojoba plants in the natural habitat of Egypt belong to different genotypes, such as the maximum values of seed yield per plant and seed oil content.
The jojoba genome reveals wide divergence of the sex chromosomes in a dioecious plant.
TLDR
The genome sequence of male and female jojoba (Simmondsia chinensis) plants revealing a very large difference in the sex chromosomes suggests that dioecious plants provide a novel source of genes for manipulation of reproductive performance and environmental adaptation in crops.
Improvements in the Sequencing and Assembly of Plant Genomes
TLDR
Advances in long read sequencing technology have continued to significantly improve the results of sequencing and assembly of plant genomes, however, results were consistently improved by greater genome coverage (using an increased number of reads).
Improvements in the sequencing and assembly of plant genomes
TLDR
Comparing recent methods for long read sequencing and assembly of plant genomes shows results were improved by greater genome coverage, with the amount needed to achieve a particular level of assembly being species dependent.

POLLEN MORPHOLOGY AND THE RELATIONSHIPS OF SIMMONDSIA CHINENSIS TO THE ORDER EUPHORBIALES
TLDR
Pollen morphology supports the treatment of Simmondsia as a monotypic family, Simmondsiaceae, and the pollen morphology of two families frequently aligned with Simmondiaceae, Euphorbiaceae and Pandaceae is briefly discussed.
Sieve-element plastids, exine sculpturing and the systematic affinities of theBuxaceae
  • H. Behnke
  • Environmental Science
    Plant Systematics and Evolution
  • 2004
TLDR
The occurrence of the highly restricted PVI plastids in the Buxaceae mitigates against a close relationship between theBuxaceae andSimmondsia, Daphniphyllum andEuphorbiaceae.
The saga of the spurges: a review of classification and relationships in the Euphorbiales
TLDR
The Euphorbiales are best construed as containing a single major family, the Euphorbiaceae, as suggested by Hutchinson; the small family Pandaceae is also included in the EuphOrbiales but may not be separable from the EuphORbiaceae.
General aspects of angiosperm evolution and macrosystematics
TLDR
It is concluded that pleiomerous flowers with helically arranged parts (corresponding to the Magnolia type, though probably less elaborate), on the basis of recent evidence can still be regarded as the probably earliest floral type in angiosperms.
Anatomy of Jojoba (Simmondsia chinensis) seed and the utilization of liquid wax during germination
TLDR
Investigations concern the structure of the embryo of mature seeds and their external morphology during early germination, which shows that a mature imbibed seed contains approximately fifty percent liquid wax.
Proposed new realignments in the angiosperms
Our attempt at putatively phylogenetic classifications of Angiospermae, considering our vast ignorance of more than 120 million years of evolution of the class, must be very tentative and elastic to
Types of Resting Nuclei in Orchidaceae
TLDR
The present author has reported in a preliminary papers that the resting nuclei of the species of Orchidaceae showed variation in the morphological characteristics of chromatins and that they can be classified into three categories : diffuse nucleus, chromocenter nucleus and prochromosomes nucleus.
An Updated Phylogenetic Classification of the Flowering Plants
TLDR
This update of the classification of the flowering plants, or Angiospermae, is based upon about 800 pertinent books, monographs, and other botanical papers published since my last synopsis appeared in the Nordic Journal of Science in 1983, and attempts to indicate relationships among the superorders, orders, and suborders.
MEIOSIS IN JOJOBA, SIMMONDSIA CHINENSIS
TLDR
The meiotic process of microsporogenesis in jojoba was characterized by using young flower buds collected from natural stands and the frequent appearance of a darkly-staining body resembling a B chromosome suggested the polyploid nature of this plant.
