A genus of small dwarf trailing hairy herbs with small entire or toothed leaves and rather large purple flowers. In character it is very close to Alys-sum, with the exception of the lateral sepals being saccate at the base. There are about six species known, from the Mediterranean region. Named in honour of a French botanical draughtsman.

1. A. deltoldea (fig. 36). - There are several varieties of this, differing in the size and brilliancy of their flowers from the typical plant. The best one in cultivation is that named Camp-bellii, which is much larger in the flower, and apparently a freer bloomer. A. purpurea, of larger stature, with larger deeper violet flowers, is held by some to be a distinct species, including Campbellii, grandiflora, and Graica. They all flower in Spring.
