Cyrtanthus seeds do not last long, typically losing viability after only one year or so. I have never heard of someone succeeding in germinating Cyrtanthus once the seeds had been frozen, so even if there are seeds stored, chances are slim that it would aid in the preservation of the species. The plants grow in a fairly inaccessible ravine, but only in one locality and the population totals less than 500 plants as far as I know. The two main threats are over-collecting and lack of breeding success in the habitat.
