R. chinensis var. mutabilis (sample no. 29) was first reported in our study, and it presented in the Synstylae-Chinenses clade with an unresolved position (Fig. 1), which may be due to its remarkable variation in the flower color during blooming (Table 1). Nevertheless, more comprehensive molecular studies are still needed to ascertain the position of this peculiar species.

The relationships among the Tea accessions in the 3-D analysis were the same as in the dendogram, except for one accession. 'Mutabilis' (C23) sorted into the Tea Type cluster [close to Jean Bach Sisley] on the dendogram, but here is found to be outside of the tighter Tea cluster and nearer to the main China group.

Two more China class roses are also located just outside the main group, between the China Roses and the Tea Types. 'Mme. Laurette Messimy' and 'Mutabilis' (C9 and C23) also have the same haplotype as OG3 [R. odorata var. gigantea].....'Mutabilis' has long been considered a China Rose by most references, and is the best example of one of the China Rose traits - darkening from bud through aging bloom (Dickerson, 1992). However, at least one source can be found that puts forth the opinion that it may be derived in part from the Tea Roses (Thomas, 1980). Both the SSR and chloroplast data support this hypothesis that 'Mutabilis' has strong Tea influence in addition to China Rose heritage.

"China Rose is the vigorous parent of many of today's hybrid roses and seems thankfully resistant to the diseases that plague its highly-bred progeny. The remarkable thing about this variety is the way the 2" single flowers change from buff to apricot to dark pink as they age, so one shrub will be decorated with all three colors at once! The fragrance is similar to a Tea Rose, and it blooms sporadically from spring into fall, with heavy flowering in late spring. New foliage and stems are a beautiful, deep red on a 4-6' semi-evergreen, rounded shrub form. One source indicates this plant is hardy in zone 6, but a protected location is probably necessary. Not native."

R. mutabilis is currently considered as a member of Sect. Chinenses although its origin is obscure (Jacob et al, 1993). This fact, together with its close link to R. moschata (Sect. Synstylae), suggests that the status of R. mutabilis should be reviewed.
