Numbers of flowers

In basionym c. 20 flowers, but we found specimen from lowland, sample from Jambi have c. 20 flowers or more, but sample from highland (c. 800 - 1200 m above sea level) have often less than c. 20 flowers, for example in photo above c. 9 flowers. The low land have a bit blurred colour, but from highland have attractive bright colour, but we think this just variety colour form.
