4. Fruit jointed (Lomentaceae). The fruit is divided by 

 transverse walls into as many spaces as there are seeds, and de- 

 hisces at maturity, generally transversely, into a corresponding 

 number of nut-like joints (" articulate-siliqua.'') 



O : Crambe (Kale, Fig. 408). The fruit has only 2 joints. 

 The lower one resembles a short, thick stalk, and is barren, the 

 upper one is spherical, and has 1 seed. Cakile (fl. maritime/,, Sea- 

 kale) ; the lower node is triangular, 1-locular, the upper one more 

 ensiform, 1-locular (Fig. 409). 



O : R'tphanus has a long siliqua, which, in the garden 

 Radish (E. sativus), is spongy and slightly abstracted (Fig. 411), but

neither opens nor divides transversely (a kind of dry berry), and 

 which in the Wild Radish (R. rapkanistrum) (Fig. 410) is abstricted 

 in the form of a string of pearls, and separates into many joints. 

 I?, sativus ; the " Radish " is formed by the hypocotyl, after the bursting of 

 its external, cortical portions (of which there are generally two patches at the 

 top of the Radish). 



5. Siliqua indehiscent (Nucumentacere). The fruit is a 

 short, unjointed, unilocular and 1-seeded nut, and the fruit-stalks 

 are often long, slender, and drooping. (Sometimes a thin endo- 

 sperm is present). Isatis (Woad) has most frequently an oblong, 

 small-winged nut; O || (Figs. 412, 413). Bunlas ; Neslia.
