These, with their modifications, and all the relative circumstances which enter into the botanical description of a plant, constitute the subject of glossology, the details of which, involving the definition of some hundreds of terms, are here omitted; because to those conversant to them it would be of little use, and those who have them still to learn will find it more convenient to have recourse to some elementary work, where most of them are illustrated by figures.

1824, J[ohn] C[laudius] Loudon, “Glossology, or the Names of the Parts of Plants”, in An Encyclopædia of Gardening; Comprising the Theory and Practice of Horticulture, Floriculture, Arboriculture, and Landscape-gardening, including All the Latest Improvements; a General History of Gardening in All Countries; and a Statistical View of Its Present State, with Suggestions for Its Future Progress, in the British Isles, 2nd enlarged edition, London: Printed for Longman, Hurst, Rees, Orme, Brown, and Green, Paternoster-Row, →OCLC, page 122:

I beg leave to differ from you in printing the etymology of names that are from the Greek in English, and not in Greek letters. I think they would answer the end in view much better if they were in Greek characters; it would be far more conducive to a general knowledge of botanical glossology, and a greater stimulus to the student.

1827 August 17, J. P., “Art. VIII. Retrospective Criticism.”, in J[ohn] C[laudius] Loudon, editor, The Gardener’s Magazine, and Register of Rural & Domestic Improvement, volume III, number 11, London: Printed for Longman, Rees, Orme, Brown, and Green, Paternoster-Row, published January 1828, →OCLC, part III (Miscellaneous Intelligence), page 370:

In 1843 [Friedrich Traugott] Kützing published his "Phycologia Generalis", accompanied by eighty anatomical plates of unrivalled excellence and beauty. […] The chief excellencies of the book are its anatomical illustrations: its faults are, the needless alteration of established names; the introduction of unnecessary glossology; and the multiplication of Orders, genera, and species, many of them grouping together plants but little related, and others separating nearly allied species.

1852 July, William Henry Harvey, “Sub-class II. Rhodospermeæ, or Red Algæ”, in Nereis Boreali-Americana: Or, Contributions to a History of the Marine Algæ of North America (Smithsonian Contributions to Knowledge; volume V, article 5), Washington, D.C.: Published by the Smithsonian Institution; New York, N.Y.: G. P. Putnam & Co., published March 1853, →OCLC, pages 4–5:

Amongst the causes which have contributed to obscure this branch of Botany, we must especially allude to the prevalence of the habit indulged in by many authors of creating a special nomenclature without regard to that of their predecessors; the slightest structural modification is no sooner recognized than a new term is invented for it, so that the same organ has received several names; and, to add to the complication, the same name has been on several occasions applied to different organs. This redundant glossology which even [Carl] Linnæus termed a calamity ('Verbositas præsente seculo calamitas scientiæ') has always proved an obstacle to the progress of science.

On the other hand, it is also possible that a true neophilia exists along with the paleophobia.

A number of typical riparian, reed-dwelling, woodland and tall open forest species that forage in the shrub and ground layers were possibly reduced in abundance and absent (e.g. muscicapids, cuculids, malurids, acanthizids, sylviids).

1991, Queensland Naturalists' Club, Queensland Naturalist, volumes 31-35, page 56:
