Red List analysis for taxonomic sections of subg. Vireya

The greatest numbers of Red List taxa are in taxonomic sections Schistanthe : euvireya (59 taxa) and Schistanthe : malesia (34 taxa); those two sections also had the greatest numbers

Taxonomic section Red List score = sum of ranking scores for four

Red List factors ( Table 4). Maximum score = 40

Schistanthe : malesia 33

Schistanthe : euvireya 33

Hadranthe ( Phaeovireya) 32

Schistanthe : solenovireya 25

Siphonovireya 23

Pseudovireya 23

Albovireya 21

Discovireya 17

Schistanthe : linnaeopsis 15

Schistanthe : saxifragoides 0

of Data Deficient taxa ( Fig. 2, Table 4). Ranking of taxonomic sections by percentage of taxa Red Listed ( Table 4), reveals that Pseudovireya and Schistanthe : malesia have the highest percentages, while Siphonovireya and Hadranthe ( Phaeovireya) have the highest percentages of taxa rated Data Deficient. The Red List score shows that Schistanthe : malesia, Schistanthe : euvireya (equal first rank), and Hadranthe ( Phaeovireya) are priority taxonomic groups for conservation ( Table 5).
