Abstract

The present paper describes the distribution, natural habitat and phenology of some terrestrial orchids in Shimoga district, Karnataka. The phenophases viz., leafing, flowering, fruiting, fruit dehiscence are observed for 25 orchid taxa belonging to 13 genera in Shimoga district. They are Dienia ophrydis (J. Koenig) Seidenf., Disperis zeylanica Trimen., Epipogium roseum (D. Don) Lindl., Eulophia spectabilis (Dennst.) Suresh., Geodorum densiflorum (Lam.) Schltr., Habenaria crinifera Lindl., Habenaria elwesii Hook f., Habenaria furcifera Lindl., Habenaria grandifloriformis Blatt. & Mc Cann., Habenaria heyneana Lindl., Habenaria longicorniculata J. Graham., Habenaria multicaudata Sedgw., Habenaria plantaginea Lindl., Liparis deflexa Hook. f., Liparis odorata (Willd) Lindl., Malaxis versicolor (Lindl.) Abeyw., Nervilia concolor (Blume) Schltr. Nervilia crociformis (Zoll. & Moritzi) Seidenf., Nervilia infundibulifolia Blatt. & Mc Cann., Nervilia plicata (Andrews) Schltr., Pecteilis gigantea (Sm.) Raf.. Peristylus plantagineus (Lindl.), Peristylus spiralis A. Rich., Satyrium nepalense D. Don, Zeuxine longilabris (Lindl.) Trimen. Phenology is the timing of plant life cycle events. Regular field visits were carried to observe the different life events. Most of the terrestrial orchids complete their life cycle in April to September or October month. The present research gives additional phenological aspects of terrestrial orchids in Shimoga district. Vegetative phenology is important to understand the ecology and instinct history of a plant species and may help to develop the conservation strategies of endangered species.
