Psydrax Fragrantissima
''Psydrax'' is a genus of flowering plants in the family Rubiaceae. It consists of trees, shrubs, and a few lianas in the paleotropics. Taxonomy The genus was named by Joseph Gaertner in 1788 in his book, '' De Fructibus et Seminibus Plantarum''. ''Psydrax'' is a Greek word meaning a blister or bump. Gaertner may have chosen this name to refer to the warty fruit or the pimply seeds of some species. The name was hardly ever used after Gaertner proposed it because most authors placed these species in '' Canthium''. ''Psydrax'' was reinstated in 1985 and 37 African species were transferred to it from '' Canthium''. The monospecific genus ''Mesoptera'' was also sunk into ''Psydrax''. ''Psydrax'' was shown to be monophyletic in a molecular phylogenetic study. It is closely related to ''Afrocanthium'', '' Cyclophyllum'' and '' Keetia'', genera that have been segregated from '' Canthium''.

Psydrax Odorata
''Psydrax odorata'', known as ''alahee'' in Hawaiian, is a species of flowering shrub or small tree in the coffee family, Rubiaceae. It is native to the Pacific Islands, New Guinea and Australia. Description The species range from in height, has a spread of , and a trunk width of up to . The leaves are glossy green in colour, are up to long and elliptic. The fruits of the plant are quite round, are black in colour and 3/8 wide. Ecology The fruits produce many seeds which are often attacked by the larvae of '' Alucita objurgatella'', a species of the many-plumed moths. Habitat The species can be found growing in dry shrub land and in dry to moist forests at elevations of up to . Uses Native Hawaiians used the very hard wood of ''alahee'' to make ''koi alahee'' (adzes for cutting softer woods such as ''Erythrina sandwicensis''), ''ōō'' (digging sticks), and ''o'' (short spears). A black dye was made from the leaves A leaf (plural, : leaves) is any of the principa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Fructibus Et Seminibus Plantarum
''De Fructibus et Seminibus Plantarum'', also known by its standard botanical abbreviation ''Fruct. Sem. Pl.'', is a three-volume botanic treatise by Joseph Gaertner. The first volume was published in December 1788. The second volume was published in four parts, in 1790, 1791, 1791 and 1792 respectively. A third volume was published after Gaertner's death by his son Karl Friedrich von Gaertner from 1805 to 1807; this final volume is also known as Supplementum Carpologicae, abbreviated as ''Suppl. Carp.''. Most of the illustrations for the work were done by Johann Georg Sturm (1742-1793). ''De Fructibus'' was based on specimens of over a thousand genera, including Australian and Pacific specimens from the collection of Sir Joseph Banks, and South African specimens from the collection of Carl Peter Thunberg. It was essentially a study of fruits and seeds, but the resultant classification was outstanding for its time. Julius von Sachs claimed that the work "forms an epoch in the his ...

Segregate (taxonomy)
In taxonomy, a segregate, or a segregate taxon is created when a taxon is split off from another taxon. This other taxon will be better known, usually bigger, and will continue to exist, even after the segregate taxon has been split off. A segregate will be either new or ephemeral: there is a tendency for taxonomists to disagree on segregates, and later workers often reunite a segregate with the 'mother' taxon. If a segregate is generally accepted as a 'good' taxon it ceases to be a segregate. Thus, this is a way of indicating change in the taxonomic status. It should not be confused with, for example, the subdivision of a genus into subgenera. :For example, the genus ''Alsobia'' is a ''segregate'' from the genus ''Episcia''; The genera ''Filipendula'' and ''Aruncus'' are segregates from the genus ''Spiraea''.
