Discussion
Two other cult. spp. and one hybrid that would key to S. prunifolia occasionally escape. S. thunbergii Siebold has lance-linear, sparsely serrate lvs and sessile or subsessile umbels with 3-6 fls on glabrous pedicels 1-1.5 cm. S. chamaedryfolia L. has ovate or ovate-oblong lvs with numerous sharp teeth, and peduncled dense corymbs of fls with exserted stamens, terminating leafy branches. S. ×vanhouttei (Briot) Zabel, the Bridal wreath, has rhombic-ovate to obovate lvs few-toothed above, and peduncled corymbs of fls with short stamens, terminating short leafy branches.
