This image from last autumn (late October) was taken in the E.H. Lohbrunner Alpine Garden here at UBC. Since no cultivar name is specifically assigned for this plant, it suggests that it is either an unidentified cultivated variety or grown as a seedling (and therefore would not be the same as its parent, even if its parent was a named cultivar). The peculiar notation, "[Dissectum Viride Group]", adds some information, indicating that this plant belongs to a Group of dissected-leaf Japanese maples from cultivation.
Missouri Botanical Garden has a gardening factsheet available: Acer palmatum var. dissectum [Dissectum Viride Group].
I used a different piece of software for processing this photograph--a program that merges two (or more) photographs taken at different planes of focus. It looks like I'll have to play with some of the settings, as the photograph appears a bit too saturated.
