The Pursuit
The search for this species was the most thrilling one. Considering its resemblance to the species it is very difficult to differentiating this variety. Only way is to wait for the flowers. The relatively low altitude of the species is an advantage to track it. I found the species from a couple of locations in 2011, however thought it would be the species one and missed it. However in 2012, I found this in bloom accidentally. I was crossing a tributary of River Teesta over its high bridge, suddenly spotted something on the rocks on the river bank which is almost 150 ft below. Pulled out the binoculars for a closer look. However, identifying them from that distance was very difficult, but confirmed that something is in bloom there. The descend down to the river was something I will not forget. The river sides were like vertical slopes, the season was early summer, so no grass or plants to help in going down. The available bamboos from the area was of very small length to touch the bottom. No local people were also there to help. Walked up to the near by village to get some help. Two known people were there and were ready to come with me. They carried some good length rope also. Tied the rope to the near by tree and we slowly climbed down, with knee and chest rubbing on the rough rocks of the valley repeatedly. Finally reached down with a lot of cuts and bruises all over the body. Walked to the river side climbed up the rock and found that the one in bloom is the variety of Bulbophyllum reptans Lindl. It was one of the few times I experienced joy and pain at the same time. The joy was the find and the pain was from the cuts on my body. Not to mention that the find of an undocumented species will always make joy overcome all the pains and sufferings. Documented the variety very well. Only after a few minutes of rest, decided to climb up. It was more difficult than going down. The descend took hardly 15 minutes, but the ascend was not even finished even after an hour. The two friends put all their efforts to safely pull me up to the road. I will never forget those people, I owe this find to them.
