Rosa rubus Lévl. & Van.
[includes detailed description of Rosa rubus], followed by:
R. mulliganii Boulenger
Near to Rubus, but the leaflets sometimes seven and the flowers larger on more slender pedicels up to 1½ in. long, in a laxer inflorescence. It was raised in the R. H. S. Garden at Wisley from seeds collected by Forrest during his 1917-1919 expedition to Yunnan and was named by Boulenger in honour of Brian Mulligan, then Assistant to the Director at Wisley, who sent him specimens for identification.
A rose distributed as R. longicuspis is near to R. mulliganii and possibly from the same batch of seed.
