“Smallest Waterlily in the World Saved from Extinction – by Kew Gardens” (Guardian), “Nymphaea thermarum” (Royal Botanic Gardens, Kew), and “Waterlily Saved from Extinction” (BBC) are stories about a water lily from Rwanda. Here is an excerpt from the BBC story:

Water lilies 635.93329
Water lilies—botany 583.29
Water lilies—floriculture 635.93329
A work limited to botany of water lilies would be classed in 583.29 Nymphaeales, which has the class-here note “Class here Nymphaeaceae (water lilies).” Since the genus Nymphaea is not mentioned in the schedule—unlike the family Nymphaeaceae—and there is no note like that at 583.734 Rosa (Roses) “Subdivisions are added for the genus as a whole and for individual species,” the classifier should assume that the genus Nymphaea does not approximate the whole of the number 583.29 Nymphaeales and that no further addition is possible for a work limited to the genus Nymphaea.
The interdisciplinary number for water lilies and the number for technology of growing water lilies is 635.93329 Water lilies—floriculture (built with 635.93 Groupings by life duration; taxonomic groupings plus 329 from 583.29 Nymphaeales, following instructions at 635.933–635.938 Taxonomic groupings). An example of a work classed in 635.93329 is Waterlilies and Lotuses: Species, Cultivars, and New Hybrids. A work on lotuses alone would be classed in 635.9333 Lotuses—floriculture (built with 635.93 plus 333 from 583.3 Ranunculidae, which has the including note “Including . . . Nelumbonales (lotuses) . . . ,” following instructions at 635.933–635.938). The work being classified, however, gives fuller treatment to water lilies than to lotuses—and even if the treatment were equal, the first-of-two rule would lead to use of 635.93329 (not 635.9333).

The biology number, 581.68 Rare and endangered plants, has the following notes:
An example of a work on biology of endangered plants is Threatened Plants of South Marlborough: A Field Guide, classed in 581.68099375 Rare and endangered plants of Canterbury Region, New Zealand (built with 581.68 plus T1—09 Geographic treatment plus T2—9375 Marlborough District, following instructions in the footnote at 581.68, instructions at 09 Historical, geographic, persons treatment in the add table under 581 Specific topics in natural history of plants, and instructions at T1—093–T1—099 Treatment by specific continents, countries, localities; extraterrestrial worlds).
At 581 Specific topics in natural history of plants is the class-elsewhere note: “Class a specific topic in natural history of plants with respect to a specific taxonomic group with the group, plus notation 1 from table under 583–588, e.g., useful monocotyledons 584.163.” Because class-elsewhere notes have hierarchical force, a work about biology of rare water lilies would be classed in 583.29168 Rare Nymphaeales (built with 583.29 Nymphaeales plus 1 General topics of natural history of plants from add table under 583–588 Specific taxonomic groups of plants plus 68 from 581.68 Rare and endangered plants, following instruction at 1 in the add table under 583–588).
The interdisciplinary and resource economics number for rare and endangered plants is 333.9532 Rare and endangered plants. In the upward hierarchy is 333.95 Biological resources, which has the class-here note: “Class here biodiversity.” Class-here notes have hierarchical force. The entry for 333.9532 has the following notes:
The last note is a footnote that allows addition of notation from the add table under 333.7–333.9 Natural resources and energy. An example of a work for which the footnote can be applied is Conserving Europe’s Threatened Plants: Progress towards Target 8 of the Global Strategy for Plant Conservation. (The Global Strategy for Plant Conservation is part of the UN’s Convention on Biological Diversity.) The work is classed in 333.953216094 Conservation of rare and endangered plants of Europe (built with 333.9532 Rare and endangered plants plus 16 Conservation and protection from add table under 333.7–333.9 Natural resources and energy —the entry for 16 has the note: “Standard subdivisions are added for either or both topics in heading”—plus T1—09 Geographic treatment plus T2—4 Europe, following instructions at T1—093–T1—099 Treatment by specific continents, countries, localities; extraterrestrial worlds).
When 333.9532 is used for a specific species or taxonomic group that does not approximate the whole of plants, no further addition is possible. An example of a work about a specific species classed in 333.9532 is Recovery Plan for Hackelia venusta (Showy Stickseed).
Where would a work limited to the botany of Hackelia venusta be classed? According to the executive summary of the work itself, Hackelia venusta belongs to the “forget-me-not family (Boraginaceae).” Also, “Hackelia venusta” is a see reference to the LCSH “Lesser showy stickseed,” and that heading has “Hackelia” as a broader term, and “Hackelia” has “Boraginaceae” as a broader term. Other reference sources also place Hackelia venusta in the Boraginaceae family, e.g., United States Department of Agriculture PLANTS Profile “Hackelia Venusta (Piper) H. St. John Lesser Showy Stickseed.” The DDC entry for 583.94 Polemoniales has “Boraginaceae (forget-me-not family)” in its including note and “Boraginaceae” linked to it in the Relative Index.
Two years ago, this delicate bloom went extinct in the wild due to over-exploitation of its habitat.
Luckily its seeds were kept in storage - and were used by Carlos Magdalena to regrow the plant at Kew Gardens - just outside London.
It took him months to find the ideal conditions for growth. He hopes now that the Thermal Lily will flourish once again in the hot springs of Rwanda.
