ARGIYREIA

(from argyreios, silvery; in reference to the silvery undersides of the leaves). Silver-weed. O RD. Convolvulaceæ. An elegant genus of greenhouse and stove climbers. Sepals five; corolla campanulate. Shrubs for the most part silvery, but sometimes silky and tomentose. The greater number of the species are robust, extensive twiners or climbers, usually requiring plenty of room to run, before they will flower. A. cuneata, and one or two others, are of dwarf habit, and produce their splendid blo oms in abundance. All the species grow well in light rich soil, or a mixture of peat, loam, and sand. Cuttings root readily if planted in sand, with a hand gla placed over them, in a little bottom heat.
