Expand description

The Plants entity builds up an hierarchical structure, see /doc/database/hierarchy.md:

§Hierarchy

This document explains the hierarchy of the plants table. Please make sure that you already read the biology section of the glossary.

§Introduction

The plants table contains entries of:

  • concrete plants, or
  • abstract plants (representants of ranks)

Concrete plants can be:

  • dragged and dropped to the map and
  • used as seed entry.

Abstract plants can be:

  • used to inherit attributes.

A concrete plant can be of following rank:

  • on species level, or
  • on variety level, or
  • on cultivar level.

Furthermore following must be true:

  • genus is below a family,
  • specie is below a genus,
  • a variety is below a specie,
  • a cultivar is below to a specie or a variety

The diagram below shows the hierarchy of entities with height and width as an example of attribute classification.

classDiagram

  class Family:::abstract {
    +int height
    +int width
  }
  class Genus:::abstract {
    +int height
    +int width
  }
  class Species {
    +int height
    +int width
  }
  class Variety {
    +int height
    +int width
  }
  class Cultivar {
    +int height
    +int width
  }

  Variety <|-- Cultivar
  Species <|-- Cultivar
  Species <|-- Variety
  Genus <|-- Species
  Family <|-- Genus

Each of these entities can have their own attributes. E.g., a variety below a specie can have different height than the specie itself.

§Unique Name

In the database we have a column unique_name. The unique name are, either for abstract plants:

  • single latin word to specify “family”, which always ends on: -aceae
  • single latin word to specify “genus”

Or is built up by several words (for concrete plants):

  • single latin word to specify “genus”
  • single latin word to specify “specie”
  • optional single latin word to specify “variety”
  • optional several words in single quotes to specify “cultivar”, which starts with a capital letter

E.g. Brassica oleracea italica 'Ramoso calabrese'

§Hybrid Names

Hybrid names are built up differently. Either two parent binomials, separated by a “x” or “×” or a given binomial, with or without an intercalated “×” (see Wikipedia). So the name does not necessarily say if a plant is a hybrid.

There is no special handling of hybrid names necessary, as the hybrid name is stored as unique name in the database.

§Displaying the Unique Name

The unique name of a plant should be displayed as follows:

  • Latin name should be displayed in italics.
  • The cultivar name should be in regular font, enclosed in single quotes (as stored in the database).

For example: Brassica oleracea italica ‘Ramoso calabrese’

The unique name alone usually is not displayed.

§Displaying the Complete Name

The complete name of a plant should be displayed as follows:

  • If there is a common name, the common name appears first and should start with a capital letter (e.g., “tomato” becomes “Tomato”).
  • If it is a plant name from the seed database, the name continues with hyphen - and the additional name.
  • This is followed by the unique name in brackets, unique name as described above in Unique Name.

The general format is:

Common name - additional name (unique name)

In cases where the common name is not available in the current language, it should be displayed as:

unique name - additional name

The cultivar is a part of the unique name.

For example (assuming Brassica oleracea italica doesn’t have a common name):

  • Italian broccoli - violett (Brassica oleracea italica ‘Ramoso calabrese’)
  • Italian broccoli - violett (Brassica oleracea italica)
  • Italian broccoli (Brassica oleracea italica)
  • Brassica oleracea italica ‘Ramoso calabrese’ - violett
  • Brassica oleracea italica ‘Ramoso calabrese’
  • Brassica oleracea italica - violett
  • Brassica oleracea italica

§Displaying the Short Name

The short name should be displayed as follows:

  • Common name or, if common name is not not available, the unique name as described above in Unique Name.
  • If additional name is available, - and the additional name should be appended.

For example (assuming Abies mariesii and Brassica oleracea italica don’t have common names):

  • Tomato - Gelbe Birne
  • Abies mariesii
  • Brassica oleracea italica ‘Ramoso calabrese’ - violett

§Usage of Plant Names

  • The short name is for overview, e.g. when you see all labels in the map editor at once (plant labels).
  • The complete name should always be given if the user wants to know precisely which plant she is dealing with, e.g.:
    • when the mouse is hovering over a plant in the plant layer,
    • in search results or
    • in plant details (left bottom toolbar).
  • The additional name must always be added if a plant is connected with a seed.

§Rules

We know about names (abstract and concrete, including hybrid):

  • If it contains more than one word, it is a concrete plant.
  • If it contains only one word, it is an abstract plant (family or genus).
  • All entries with 2 words are a specie (de: Art),
  • All entries with 3 or more words are either:
    • variety (de: Varietät) if all is spelled italic, or
    • are cultivar (de: Sorte) if last part of the name (can be more than 1 word!) is not latin, not italic, is in ‘single quotes’
  • All entries with a single x between the words are hybrid. We treat them like specie.

§Attributes

Columns are documented in their respective structs.

We prefer strongly-typed data, e.g.:

  • enums
  • array of enums
  • numbers

Columns that contain text should be postfixed with:

  • _en for English text
  • _de for German text

As we often copy data from other sources, we maintain following columns for external references:

  • external_source: an array from enum where the first entry is the “main source” the other columns refer to:
  • external_id: an identifier of that source
  • external_url: the URL from where the data was taken

Plants are additionally classified as:

  • is_concrete_plant (is a concrete plant as opposite to an abstract plant)
  • is_tree (as search help within the tree layer)

§from Permapeople

Following columns are removed:

  • environment (and its references)
  • type and is_variety, as variety is now determined from the name (rank to be calculated from name, see above)
  • wildflower
  • plants_of_the_world_online_name_synonym (redundant to link)
  • dutch_name, danish_name, french_name
  • when_to_harvest
  • propagation_cuttings
  • alternate_scientific_name
  • hortipedia
  • invasive_in
  • years_to_bear
  • useful_tropical_plants
  • thinning
  • light_tolerance
  • chill_hours, beef_tomato, invasive
  • folder_name (at least in DB)
  • native_climate_zones
  • adapted_climate_zones
  • propagation_direct_sowing

Other minor problems:

  • fix Labiatae to be lamiaceae (family rank)
  • Remove all “var.” from the database entries (staying with the 3 words).

§from Reinsaat

Unique name:

  • use Scientific name subheading together with name (as cultivar, see above) for our unique_name (Cucurbita ssp. from Scientific name kulturhinweise shouldn’t exist)
  • Remove all occurrences of L., MIll., and var..
  • Entries on Reinsaat that are spelled like “Brassica oleracea convar. botrytis var. italica” https://www.reinsaat.at/shop/EN/brassica/broccoli/limba/ exist in our database as “Brassica oleracea italica”. Add the Reinsaat entry to our database in a different row with the following nomenclature: Brassica oleracea italica ‘Limba’, with Brassica oleracea italica as parent, by following rules:
    • Remove the term “convar.” and its following word.
    • Remove the “ssp.” and its following word.
  • The name maps to cultivar (de: Sorte), i.e. a rank below variety and is expressed in non-latin words, such as ‘Limba’. In our database we want them:
    • back together in one name (the unique name, as described above) e.g. Brassica oleracea italica ‘Limba’ or Malus domestica ‘Gala’.
    • with a link to the variety, if present, otherwise species

Individual problems:

  • Daucus carota L. ssp. sativus –> Daucus carota sativus
  • Petroselinum crispum ssp. tuberosum –> Petroselinum crispum tuberosum
  • Papaver somnif. var. paeonifl. –> Papaver somniferum paeoniflorum
  • Alcea rosea fl. pl. –> Alcea rosea flore pleno
  • Campanula lat. macr. –> Campanula latifolia macrantha
  • Malva sylvestris ssp. maur. –> Malva sylvestris mauritiana
  • Sonnenblume, Velvet Queen: None should be Helianthus annuus
