Abstract: <i style="">In vitro </i>mass production of <i style="">C. suaveolens</i> (Lindl.) Hook, an endangered orchid with its snowy white flowers having horticultural potential was accomplished through immature seed culture, and subsequent plant regeneration. The developmental stage of the immature seeds and nutrient media significantly influenced the germination frequency. Seeds at 13 months after pollination cultured on 3% sucrose containing Murashige and Skoog (MS) medium with 9 µM a-naphthaleneacetic acid (NAA), and 15% coconut water exhibited 93% germination after 40 days of culture. Upon subculture, the germinated shoots on MS medium with 9 µM BA, 6 µM NAA, 3% casein hydrolysate and 0.1% activated charcoal (AC) yielded >12 shoots per shoot or bud. Addition of AC favoured the enlargement of pseudobulbs and better rooting. The plantlets transferred to community potting mix after <i style="">in vitro </i>hardening (8-10 wk) displayed 85% survival.
