    A.) Native Hawaiian carabid beetles have radiated extensively, resulting in nearly species classified in the genus Mecyclothorax. B.) No taxonomic resources are available to characterize this radiation. A.) Phylogenetic relationships are determined for the native Mecyclothorax radiation. B.) This hypothesis allows historical interpretation of the radiation, and forms the basis for defining. A Taxonomic Study of the Genus Eugenia (Myrtaceae) in Hawaii1 KENNETH A. WILSON2 THE PANTROPIC GENUS Eugenia (Myrtaceae) is represented in the forests of Hawaii by several species. A recent taxonomic treatment of the genus by Merrill and Perry () divided the greater number of species of.

    A taxonomic revision of the genus Chamaesyce (Euphorbiaceae) in the Caribbean. Thesis (Ph.D.) University of Florida. pp. Carter, Susan (): New Succulent Spiny Euphorbias . About this book. The following 24 species of scorpionfishes are recognized in the Indo-Pacific genus Scorpaenopsis Heckel, 8 of which are described as new: S. altirostris Gilbert, known from 6 small specimens (largest mm SL) trawled off Molokai, Hawaiian lslands in m, unusual in its large eye ( in head); S. barbata (Ruppell) from the seas of the Arabian Peninsula south to.

      With about species, Chamaesyce is the largest segregate genus from Euphorbia, and has a wide distribution, but most species are confined to the New World (STEINMANN; PORTER, ). Chamaesyce species are distinguished with basis on its vegetative morphology, with cyathia nearly identical to those of many species of Euphorbia subg.   After many years of survey work and research work, the authors have now brought out a comprehensive up-to-date taxonomic revision of the interesting genus for India. The genus Euphorbia has 80 species indigenous to India and 4 exotic, introduced and naturalized ones. The genus is rich in endemism with 30 species and 7 varieties endemic to India.

However, the group of plants comprising Chamaesyce is generally accepted as a natural one. The controversy concerns the taxonomic level at which Chamaesyce should best be recognized.

The name Chamaesyce was first used, at the generic rank. There are no clear reversals to C 3 photosynthesis in the Chamaesyce clade, although there is a radiation of 16 woody species in the Hawaiian Islands that includes several species restricted to. Although the majority of species in Euphorbia subgenus Chamaesyce section Anisophyllum (Euphorbiaceae) are small and herbaceous, a clade of 16 woody species diversified on.

Comments: The taxonomy of the Ground Spurges is rather confused. Some authorities assign them to the Euphorbia genus, rather than the Chamaesyce genus. Over the years, reassignment of the names of species has been rather common. Other scientific names for Prostrate Spurge include Euphorbia supina and Chamaesyce supina.

Chamaesyce is a genus of plants in the family phylogenetic studies have shown that Chamaesyce is deeply nested within the broader Euphorbia. Specifically, Chamaesyce is very closely related to plants like Euphorbia pulcherrima, the popular poinsettia (this and related plants have also been given in their own genus, Poinsettia, but are also well nested within Euphorbia).Taxon identifiers: Wikidata: Q.

In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in a taxonomic es of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc.

A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general. Koutnik D.L. () A taxonomic revision of the Hawaiian species of the genus Chamaesyce (Euphorbiaceae).
