Hi All,
  What method of reproduction is this?
I got 16 little plantlets from this one stalk with a  single flower of the Red Ginger.
Thanks,
Padmini Raghavan.

Dear Padmini,
Nice pictures; I can use them to show to my students. It is a type of
vegetative propagation where the propagules are formed on the
inflorescence axis along with flowers. If I am not mistaken each
plantlet is arising at the axil of the red bract. Do they form roots
too? I have seen it in Chlorophytum. I am not sure if it is true
vivipary; vivipary is germination of a seed while still on the mother
plant.
Thanks,
Chitralekha

This is interesting. As per definations- some plants produce seeds that undergo no dormancy . The growth while the seed and fruit are still on the plant is termed vivipary. Another defination says True vivipary, the germination of seed before dispersal is relatively rare ( as in mangrove species), in contrast to false vivipary (prolification) which represents a development of rooting vegetative buds instead of flowers. Could this be a case false vivipary?

Rashida.

Yes Rashida ji
You have got it right. Many plants develop bulbils in place of flowers. Top onion, a pseudodiploid can survive only because of this so called vivipary, and infact it was  earlier named as Allium cepa var. viviparum.

To me, this is not vivipary unless this happens all the time in the
plant. Which is clearly not the case here.
This has happened just because somehow seeds got stuck and germinated
due to availability of moisture.
True vivipary is a compulsory habit in a particular plant, where there
is no other means liek that of Mangrove shrubs or trees.
This is not even bulbil. Bulbil is also a unique character.

Pankaj
