    Re: Acer campbellii ssp. wilsonii

    I have been growing 2 forms of Acer campbellii ssp wilsonii for several years. The 1st grown from seed collected in Yunnan generally has 5 lobes, better autumn colour and more tolerant of full sun is now about 15+ years old and as shown last year, set seed. The second with 3 leaves has been far less tolerant of harsh conditions and usually the leaves are distorted by the end of summer. Shown here is a seedling from the original plant, the seedling about 10 years old. The original type has been available occasionally in Australia for some time. Both have beautiful spring foliage and are quite attractive plants but the 5 lobe form remains attractive even in full sun as shown.

    Flora of China have it listed under Acer wilsonii, don't know if that is considered the definitive classification. They also have illustrations of both the three- and five-lobed forms:

    It should be noticed that Piet C. de Jong and Herman John Oterdoom are two of the 5 authors of the section aceraceae in Flora of China. In this case I could not see any dissenting opinion so it is possible to conclude that they support A. wilsonii as being a separate species.

    Both Rushforth and Bean also treat it as a separate species.

    I have attached some photos of flowers, seed and seedlings at 2-3 months.
    On the subject of botanic naming it seems there is always the gardeners who like as many different species as possible versus the botanists who if they could get away with it would have all plants as one species "Algae" and everything else such as maples etc just "variants" of it. Current separation in Flora of China seems more evidence based than preceding divisions but Acer from other areas need the same approach.
