Ysano. Tropæolum tuberosum.

This is a perennial plant from Peru, and deserves mention as a recently introduced esculent. It produces an abundance of handsome yellow and red tubers, about the size of small pears; the taste of which is not, however, very agreeable. On this account, a particular mode of treatment has been adopted in Bolivia, where, according to M. Decaisne, they are treated in the following manner:--

The tubers designated "Ysano," at La Paz, require to be prepared before they are edible. Indeed, when prepared like potatoes, and immediately after being taken up, their taste is very disagreeable. But a mode of making them palatable was discovered in Bolivia; and the Ysano has there become, if not a common vegetable, at least one which is quite edible. The means of making them so consists in freezing them after they have been cooked, and they are eaten when frozen. In this state it is said that they constitute an agreeable dish, and that scarcely a day passes at La Paz without two lines of dealers being engaged in selling the Ysano, which they protect from the action of the sun by enveloping it in a woollen cloth, and straw. Large quantities are eaten sopped in treacle, and taken as refreshment during the heat of the day.

Propagation and Culture.--The plant may be propagated by pieces of the tubers, in the same manner as potatoes; an eye being preserved on each piece. The sets should be planted in April or May, according to the season, about four feet apart, in
