Another complication for the future is growing up in regard to R. brunonii. Its name is given in Modern Roses as R. moschata nepalensis or the Himalayan Musk Bose. We have in the Royal National Rose Society's gardens a wonderful  plant labelled 'Paul's Himalayan Musk', which is nothing like R. brunonii having duller and smaller foliage, as if it had met R. multiflora in its career; it is blessed with the greatest sweep of blossom one can imagine, a multitude of tiny flowers, pale, with a touch of lilac pink in them.

Paul's Himalayan Musk is a very vigorous climber, the origin of which appears to be unknown. As the stipules are fringed, it is probably a R. multiflora hybrid. W. paul does not mention it in his book "The Rose Garden"...

Also displayed to advantage on the Sunningdale exhibit was 'Paul's Himalayan Musk Rambler', in my view one of the most distinctive and charming of the double flowered ramblers. The fully double but flat blooms are white...

After several exploratory trips in the same neighbourhood, we made an interesting find higher up this rocky and scrub covered face, not far from a small creek and near the site of an old quarry. This was no less than a Double Pink Musk, similar to the creamy-white one we had found lower down the hillside on an earlier visit. The perfect, two-inch blooms, of a soft salmon-pink, were very lovely though the plant itself was neither as vigorous nor as floriferous as the white form. We think, from what helpful Thames residents have told us that the single Musk Roses must have been planted at a much earlier date than these charming double forms. We feel fairly certain that these were hybrids of the strong-growing Himalayan Musk produced by Paul & Sons of England; though unfortunately we saw neither of them overseas. they were Paul's Himalayica alba magna and Paul's Himalayica Double Pink; but we did see Paul's beautiful Tree Climber, with masses of very small, double, blush-white flowers, growing through two trees - one with dark, bronzy foliage, and the other with variegated leaves - in a garden, near Woking, in Surrey.
