In "Progress in Breeding Hardy Roses," Isabella Preston says,

Mohawk is of similar descent [an open-pollinated seedling of a rugosa-rubrifolia cross] but is a dwarf shrub about three feet tall although the bush is nearly twenty years old. The dull green foliage is small and leathery and the single flowers, rather brighter in color than Aster Purple, have white centers. It makes an attractive bush and flowers for two weeks in June.

In "Central Canadian Rose-Breeding," Isabella Preston, after describing the breeding of 'Carmenetta', says

Many seedlings were raised from the reciprocal cross but as all had green leaves, none was considered worthy of naming. Open fertilized seeds were sown, and a number of seedlings raised, a few of which have been named. ... Mohawk (R.26.18.04) is a dwarf plant about two feet tall. The leaves are small and the single flowers are rather brighter than aster purple. No seed-pods are formed.
