Mustard (Brassica juncea var. crispifolia)
The plant is erect, 1-3 feet tall, and leafy. Leaves may be elongated or broad with smooth margins or margins may be notched or curly. Mustard and turnip leaves are similar but turnips show more definite notching of the margins and are not curly. The midrib of mustard is broader at the bottom and tapers towards the top while turnip leaves have a midrib that is more uniform from bottom to top. Texture is lighter than collards and the midrib is light green and not as fleshy as Swiss chard. Seeds are similar to cabbage but smaller.
