Nervilias have one particular thing in common. It tend to initiate floral stalk from the underground corms only after a short rain, that is during pre monsoon. If the pre-monsoon is delayed then they can give floral shoot only if it get interrupted rain. Otherwise this plant give foliar shoot during rainy season. The blooming period is very very short. I imagine, my N. infundibulifolia bloom didnt even last for 3-4 hrs...... In such short time I imagine how it manages to get pollinated......SO.....to compensate this, they grow in large bunches....I have seen patches of Nervilia prainiana, N. aragoana, N. gammieana at different places, where number of individuals were more than 1000s.....
Orchids have mind too :)) Pankaj
