Eupatorium deltoideum, Jacq. By C. Sprenger (Bull. B. Soc. 

 Tosc. Ort. 1-2, 1907, p. 13). — Woody evergeen shrub with long-stalked 

 leaves, which are triangular, almost cordate, with denticulate and serrate 

 bases, green above, pale green below, with opposite veins ; large flowers 

 in elegant rose-purple umbels and of great value for our gardens and 

 markets. The species was found and described by Dr. Jacquin, who died 

 at Vienna in 1817, but it had never been introduced alive into European 

 gardens. Last year, however, among many seeds collected by the traveller 

 C. A. Purpus in Mexico, in the vicinity of Salto d'Agua, about 1,000 metres 

 above sea-level, were those of this marvellous Eupatorium, which flowered 

 in the writer's garden at Vomero for the first time in Europe uninter- 

 ruptedly from October to December, and in the first year after sowing, 

 as if it were an anuual. It is hardy there, but loses its leaves. The 

 plant is very graceful, and can be used in all sorts of ways for decoration, 

 &c. It can be propagated by seed and cuttings, which latter strike 

 readily ; its cultivation is easy. The seeds are sown in April, and the 

 seedlings transplanted early and frequently. The treatment is much 

 the same as that for autumn chrysanthemums, when it will yield an 

 abundance of flowers in autumn. Light but substantial soil must be 

 used and plenty of manure applied. Jacquin preserved shoots of it in 

 his herbarium, and has a figure of it in his work " Icones Plant.
