The sporophyte survival rate was recorded as indicated after transplanting into ex vitro conditions. The percent ages of survival were 95, 88, 90 and 95% in sphagnum, vermiculite, peat, and a mixture of vermiculite and peat, respectively. We did not detect a significant difference in survival rate among the various media ( =7.81). Several randomly selected samples that had survived in each potting medium were removed from their containers and examined.
