Published in Bot. Repos. 7: 483 in 1807:
This double-flowered dwarf Dahlia is certainly the most attractive of the genus. It is supposed to be only a variety of the D. pinnata, but the variation is almost powerful enough to constitute a species; as, besides the difference in its flowers, we have never found it arrive to more than half the height of the pinnata, although we have seen it every autumn for four years in luxuriant bloom.
