Northern India. Tropseolum. — The annual members of this genus are popu- larly known as Nasturtiums ; they belong to the order Tropceolacece, and would appear to be closely allied to the Cranesbill family, Geranlacece. The name comes from tropcvum, "a trophy," from the fact of the flowers resembling a helmet, and the leaves a shield. These plants enjoy good rich soil and thorough drainage; the green- house kinds should have a wire trellis to scramble over, and the hardy kinds make a fine appearance on rockwork, and especially when growing through and amongst tall shrubs ; these latter may be left in the ground through the winter, but the green-house species require to be kept dry after the leaves die away. T. azureum—a slender scandent plant, having small peltate leaves, with from five to seven ovate, dark green seg- ments ; the flowers produced singly upon slender peduncles, and bright blue. Green-house. Spring months. Chili. T. brachyceras—similar in growth to the preceding, with bright yellow flowers. Green-house. Spring months. Chili. T. Jarratti—leaves peltate, divided into entire dark green segments; flowers rich scarlet and yellow. Green-house. Spring months. Chili. T. polyphyllum — this plant reaches Orchis Mascdla some three or four
