Orchid Lessons By Naresh Swami – Translucent pseudobulb.

While I was in the 6th class, our Biology teacher demonstrated an experiment to help us understand the way in which water is transported in a plant, with the help of Balsam plants and coloured water. A Balsam plant is placed in a beaker filled with coloured water. After some time we saw the coloured water slowly rising up the stem. She further explained that the Balsam plants are particularly used because they have translucent stems, so that we can see the coloured water moving up the stem. Hence, whenever I think about the word “translucent”, I remember those Balsam plants.

However, it is not just the Balsam plants that have translucent characteristics, a few orchids also have this unique characteristic, even though the phenomenon is very rare. 

Presented here is Pholidota protracta Hook.f., with its translucent pseudobulb.

Orchid Lessons by Naresh Swami – Resupinate and non-resupinate flowers.

Resupination in orchid flowers is the process by which the pedicel twists to position the lip at the bottom side of the flower. Orchid flowers have one of its petals modified as “lip”, usually the top one. As the bud develops, its pedicel makes a 180° twist to arrange the lip at the bottom side. It has proven that this twist happens to position the lip in such a way to make itself a landing pad for visiting pollinators.

Those flowers with lip at the bottom are called resupinate flowers and those at the top are called non-resupinate flowers (or not resupinate). Majority of the orchids have resupinate flowers.

It may be tricky to understand, hence, I am making it simple here. Look at the 2 pics carefully, flowers with the apex of the lip pointing downward are called resupinate flowers and the other, pointing upward are called non-resupinate flowers.

Orchid Lessons by Naresh Swami – Jewel Orchids

Orchid leaves are generally green in colour, with parallel veins converging to both ends. However, a few of the ground orchids (also rarely some epiphytic ones) bore green to brown or reddish-brown mottled (with irregular marks, blotches or patches), variegated (with zones of different shades of colour) and reticulated (with net like veins) leaves. Due to their beautiful leaf colouration and vein patterns, these orchids are called “Jewel Orchids”. Many species from the genera Anoectochilus, Corybas, Goodyera, Neottia, Paphiopedilum, Zeuxine etc., are examples of “Jewel Orchids”, with astonishingly beautiful leaves. These orchids with their attractive leaves are very decorative even when not in flower, hence is of great demand among orchid growers and enthusiasts across the globe.

Orchid Lessons by Naresh Swami – Bulbophyllum

Bulbophyllum is the largest genus among all orchids with the highest species diversity in India. The plants are generally perennial, with most of the species growing on tree trunks (epiphytic) or boulders (lithophytic). Many species are gregarious in nature, covering up the whole tree trunk or the boulder where it occupies.

Introduction

My love for orchids started in 2009, during my college days. I was attracted to each find, and visited many habitats in the eastern Himalaya, to locate more species. Even though the days of visit were restricted to around 2 months each, in the summer and early winter, I was credited with many interesting finds.

However, in those days, identifying even popular road side orchids was very difficult. The only available records to identify them were drawings made way back in 1890s and few recent books that exactly copied those drawings.

Thanks to my association with Shri Karma T. Pempahishey of Holumba, Kalimpong, I was introduced to different types of literature on orchids that turned my love towards this most fascinating plant family to a detailed research oriented study. Along with all the literature, he turned out to be the inspiration behind my change in attitude towards in-situ orchid study. His guidance led me to concentrate on the iconic book, The Orchids of the Sikkim-Himalaya, by Sir George King and Robert Pantling (1898).

On completion of my college days and submission of thesis, I returned to the Himalaya only to concentrate on the above mentioned iconic book. The book describes 449 orchid species, of specimens brought from various habitats and illustrated with hand drawings. Interestingly, only a limited number of copies were made and finding an original copy is as difficult as finding many orchids described in the book.

From the mid of 2011 to the end of 2014, the days were turbulent as well as jubilant, with intense pursuit for various orchid species all across the region of Sikkim-Himalaya. The turbulent days were due to new terrain, inclement weather etc., and the jubilant times were those days with finds that were not reported or seen after the publication of the iconic work of King & Pantling. By the end of 2014, after a mammoth 45,000 km on foot, the count of species I documented stood at 564, a staggering increase from the original number of 449 species described in the iconic work.

With the advent of social media, I started a page on Facebook, titled, The Orchids of the Sikkim-Himalaya, with daily uploads of each and every species that I located, with the sole intention of popularizing each species and help with proper identification. The page now has thousands of photographs and hundreds of species, members, visits etc., which help people around the world in their study of orchids, research, etc., a resource I missed in my early days of study.

Since 2015, I am in Arunachal Pradesh as an extension of my pursuit on orchids in the eastern Himalaya. Unlike Sikkim-Himalaya, where I had an iconic reference book, in Arunachal Pradesh there was a void. The few books available on Orchids of Arunachal Pradesh did not enable any reference. The remoteness, lack of communication, heavy monsoons played spoilsport in the initial days of work. Later on, I overcame all difficulties and was able to work steadily and till date am able to document more than 700 species from the region.

Till now, I travelled more than 90,000 km into uncharted and often dangerous locations in the eastern Himalaya, that include arduous treks, cycling, motor cycle rides, swimming across turbulent waters and even paragliding and parachuting into the deep tracts of    unknown forests looking for orchid species. The entire work till now, produced documentary evidence of more than 1300 species of orchids and made possible the publication of two books on orchids, Terrestrial Orchids (April, 2016), Orchids of Ziro: Arunachal Pradesh (November, 2017) and the launch of a mobile application – a first of its kind, The Orchids of the Eastern Himalaya (September, 2018; updated on July/2019).

My long stay in the Himalaya, made me publish another book, HIDDEN Treasures: Rare Plants of the Alpine Himalaya (February, 2017), a collection of 100 rare to very rare alpine plants, including 14 new reports for India, all found above 15000 ft in the eastern Himalaya.
