Citrus

Most citrus fruit trees are grown as a "grafted combination" of: a scion (good-fruit-quality tree) on the top; and a rootstock - cultivar which resists or tolerates infection by certain disease(s), that forms the lower trunk and root system.

Examples of rootstocks:

  1. Trifoliate Orange, Janpanese bitter orange (Poncirus trifoliata), 2n=18
  2. Grapefruit (Citrus×paridisi)
  3. Cleopatra mandarin (Citrus×reshni)
  4. Orange (Citrus×aurantium)^
  5. Citrumelo = 1 × 2: Poncirus trifoliata × Citrus×paridisi
  6. Citroncirus/Citrange = 1 × 4: Poncirus trifoliata × Citrus×sinensis


^ Sweet orange (Citrus×sinensis, or Citrus×aurantium var. sinensis)
= Citrus maxima (pummelo) × Citrus reticulata (mandarin)

Bidens odorata

Re: iNaturalist Updates: Flag for Taxon - Bidens pilosa (Blackjack) [See Note]
https://www.inaturalist.org/flags/362565


It was mentioned that the species named Bidens odorata, which is very similar to Bidens pilosa / Bidens alba / Bidens alba ssp. radiata, is applicable to Mexico and Guatemala.

Over 100 research grade observations of Bidens odorata were identified during year 2020 @iNaturalist (retrieved on April 6, 2021). I randomly picked 6 (as listed below) of them for a better understanding:

  1. August 27, 2020

  2. September 19, 2020

  3. October 30, 2020

  6. December 29, 2020
    https://www.inaturalist.org/observations/68041832


There are four varieties of Bidens odorata @iNaturalist:-

  • chilpancingensis
  • oaxacencis
  • odorata
  • rosea

Only one observation falls into these varieties:
Bidens odorata var. odorata: https://www.inaturalist.org/observations/6842627
