Ranking by Total Score

Total Score, which prioritises groups for ex situ conservation, shows that geographic origins New Guinea, Sumatra, and Sulawesi should be assigned highest priority ( Table 12). These three origins are in the top three ranks for both component scores, and while New Guinea has more taxa than the other two origins, Sumatra and Sulawesi have high percentages of taxa in the factors that generate the component scores. Because these three origins are in the top ranks for both component scores, they take top priority for both in situ and ex situ conservation. In contrast, although the Philippines has a relatively high Red List score, its taxa are relatively well represented in cultivation, so it ranks sixth for Total Score and has a lower priority for ex situ conservation. Vietnam is similarly placed: good representation in cultivation reduces its ranking in Total Score compared with its Red List score. The origins with the lowest priority for ex situ conservation according to Total Score are India, Australia, and Malayan Peninsula, although only five taxa in total come from these origins.

For taxonomic sections, Total Score shows that Schistanthe : malesia and Hadranthe ( Phaeovireya) are equal first ranked (and take the top two ranks in both component scores), followed by Schistanthe : euvireya ( Table 13). Of the other taxonomic sections, Discovireya is as poorly represented in cultivation as Schistanthe : euvireya, but it has a much lower Red List score, and is only mid-ranked for Total Score. Siphonovireya has a lesser conservation issue than Schistanthe : solenovireya, but ranks more highly in Total Score because of poorer representation in cultivation. Using the Total Score method, the taxonomic sections with the lowest priority for ex situ conservation are Malayovireya and Schistanthe : linnaeopsis.
