Taxonomy and naming

The first formal description of this species was by
John Lindley John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley w ...
in 1837. The description was published in W. J. Hooker's ''Companion to the Botanical Magazine'' from a dried specimen that Lindley had received. Lindley gave it the name ''Chrysorhoe nitens''. The type specimen for this species was first collected in the 1830s somewhere around the

"by (?) Toward." Lindley recognised its similarity to ''Verticordia'' but raised the new genus, noting differences between the two genera. In 1838,
Stephan Endlicher Stephan Ladislaus Endlicher also known as Endlicher István László (24 June 1804, Bratislava (Pozsony) – 28 March 1849, Vienna) was an Austrian botanist, numismatist and Sinologist. He was a director of the Botanical Garden of Vienna. Bio ...

and the name ''Verticordia nitens'' (Lindl.) Endl. is widely accepted. Schauer made a similar change of genus in 1841, apparently unaware that Endlicher had already published. Lindley apparently did not agree with the change to ''Verticordia'', recording in his 1840 book, '' A Sketch of the Vegetation of the Swan River Colony'' - "by Dr. Endlicher it is reduced to the genus ''Verticordia'', but I think the character assigned to it in the work alluded to is sufficient to define the genus." When Alex George reviewed the genus in 1991, he revived Lindley's epithet and placed this species in subgenus ''Chrysoma'', section ''Chrysorhoe'' along with '' V. aurea'' and '' V. patens''. ''Verticordi aurea'' has larger flowers and broader staminodes, and ''V. patens'' has lemon-yellow flowers, lobed staminodes, a much shorter style and an earlier flowering period.

Cultivation

The plant was regarded as highly desirable by gardeners in England. The spectacular display, "strikingly beautiful", was expected to be marketable, yet it has presented difficulties in its propagation. It was introduced to English gardens in 1840, but was not known to have flowered until 1861. The introduction to the eastern states of Australia has met with some success, due to the refining of the technique of propagation and the application of early pruning. Heavy pruning was first suggested by James Drummond, an early collector and promoter of the region's flora. The species was mentioned in the early survey, '' A Sketch of the Vegetation of the Swan River Colony'' ('' Edwards's Botanical Register'', 1837), which was referred to an 1861 notice in ''

in the nineteenth century is lacking evidence and detail. Later cultivation techniques made use of cuttings from lower parts of the plant, propagated from soft to semi-hardened wood, to produce longer living specimens. Cuttings taken between autumn to spring strike readily. Seedlings produced in cultivated gardens are rare, due to the absence of its pollinator. The need for study and development of cultivation techniques was identified by Alf Gray in 1966, and suggested this was not beyond regular commercial interests. Early attempts showed poor development in root structure, and susceptibility to fungal diseases present barriers to development as a crop or garden plant. The species has been less successful as an introduction to the eastern states, suffering fungal conditions after rains and remains vulnerable to root rotting—attributed to ''

''—in dryer conditions that spare other plants. All members of ''V.'' sect. ''Chrysorhoe'' are noted for the vulnerability to infection of the rapid growth of soft wood, but this is especially destructive to ''V. nitens'' in cultivation. Controls include pruning below sites of infestation, which often appear near the growing tip, results in bushier and more resilient plants for gardens, and study groups have trialled the removal of flowers after downpours. White oil controls used on other verticordia are damaging to ''V. nitens''. Techniques for cultivation for the cut flower industry, replacing the natural harvest, require further development for commercial viability.


Cultural use

The plant has traditional names Kodjeningara and Kotyeningara, and common names such as Glistening Verticordia or those deriving from Morrison—later extended to similar species—these include Morrison Featherflower, Morrison-flower, and Orange or Yellow Morrison. The name of early collector, William Morrison from Kew, was attached to ''V. nitens'', and "Morrison flower" was extended to the common name for many similar and well known species. Morrison was asked by Seymour Meares, the son of Richard Goldsmith Meares, as the botanist Drummond was unavailable to him.> Meares' request from James Mangles was to deliver material for the cultivation of "''Chrysorhoe nitens''" in England, and unable to recall this name he applied that of the collector as a label.

Cuttings of the flowers retain colour and perfume, for up to 12 months, and this is one of few ''Verticordia'' species that can be hung and dried immediately, without a period in water. Another technique applied to ''V. nitens'' involves steeping cuttings in glycerine and hot water before drying, this affects colour but avoids flowers and leaves becoming brittle. They probably comprise the greatest part of ''Verticordia'' exported by the state's cut flower industry.
