DESCRIPTIO. _Radix_ annua. _Rami_ elongati, effusi, procumbentes, angulati, superne simplices. _Folia_ ternatim verticillata, remota, elliptica, acuminata, amplexicaulia, utrinque 3-5-lineata. _Pedunculi_ ternatim verticillati, axillares, filiformes, primo patuli, demum sæpe recurvi, foliis duplo longiores. _Calyx_ 4-rarius 5-phyllus, foliolis lanceolatis, acuminatis, carinatis, marginibus membranaceis. _Corolla_ 5-rarius 4-petala, petalis basi confluentibus, patulis, orbiculatis, coccineis, basi intus nigris. _Filamenta_ 5 hirsuta, atro-purpurascentia, petalis multo breviora. _Germen_ pallidum. _Stylus_ pergracilis purpureus antheras luteas superans. _Stigma_ simplex, capitulatum, viride. REFERENCE TO THE PLATE. 1. A peduncle and calyx. 2. The corolla spread open. 3. The seed-bud and pointal, and summit magnified. This new and elegant species of Anagallis, the largest and most showy of that genus hitherto discovered, was introduced into England, we believe, in the last year; but by whom, or from what country, we have not yet satisfactorily ascertained. It is reported to be of African origin, and to have come to England from the Paris garden. Our figure was made from a plant trained up near three feet high, in Lady De Clifford’s collection at Paddington, where it is treated as a green-house plant. We have not yet seen it produce good seeds, although apparently an annual plant; but it is easily increased by cuttings in the usual way. In every thing except size, and in having more entire petals, it very much resembles Anagallis arvensis; a plant truly remarkable for being the only one indigenous to Britain (the Poppies excepted) with scarlet flowers.
