Question about fire and bulbs

Hi

There is a Amaryllis belladonna - (pure species) pale pink coloured that multiplies rapidly and rarely flowers without fire.  I learnt from a Spring back burning operation of bushland gully adjoining my property a couple of years ago that the smoke does induce it to flower quite heavily - but since then only 5 to 10% of mature bulbs will flower under ordinary garden culture.
A  new species Amaryllis paradisicola was described  by Snijman in 1998 ( found in the Richtersveld in Namaqualand)  is regarded as only flowering after bush fires.  It was collected in 1972 - and didnt flower in cultivation until 1995! A long wait until they worked out how to induce flowering.

  There are some memorable photos of geophytes blooming after a fire in 
  Table Mountain: A Natural History by Anton Pauw and Steven Johnson, but 
  unfortunately not memorable enough that I remember the species. Perhaps 
  Haemanthus sanguineus? What I do recall is that some were said to bloom 
  only after a fire.

  Some relevant articles from Veld and Flora:
  http://plantzafrica.com/veldflora/1990/…
  http://plantzafrica.com/veldflora/1998/…
  http://plantzafrica.com/veldflora/1992/…

  The last documents fire-induced flowering in Orchids.

  While we are speaking of South Africa, allow me to digress briefly to 
  ask if anyone grows Mimetes in the US.
