The natural order, Cruciferae, has given us a number of our most esteemed vegetables. The radish, turnip and cabbage all belong to this order, and all have varieties with tuberous roots. Now the mustard, of the genus Sinapis, another member of the order, has given us one in the shape of a tuberous form. It is from China, and is called Sinapis tuberosa in the Revue Horticole where it is figured, resembling somewhat small egg-shaped turnips. Its exact merits in the culinary arts have yet to be ascertained.
