reaches from one suture to the other, is ‘of equat 
breadth, we say the valves run parallel with the 
partition, (valvulis dissepimento parallelis). But if 
both valves are swelled and hollow, so that the two 
sutures stand in the centre of the pericarp, and the 
partition is much narrower than the greatest breadth 
of the fruit, we say, the valves run contrary to the 
partition, (waluulis dissepimenio.contrariis). Many va- 
rieties take place in the figure of the Siliqua*. 
* § 109. 
The recuMe, (legumen), is-a dry, elongated peri- 
carp, that consists of two halves or valves, exter- 
nally forming two sutures. The seeds are attached 
to both margins of the under suture only. The 
kinds of the legumen are, ) 
1. Membranaceous, (membranaceum), when both 
valves consist of a transparent membrane. 
2, Coriaceous, (coriaceum), when the two valves 
are of a thicker and tougher substance. 
3. Fleshy, (carnosum), when the two valves con- 
sist of a soft fleshy substance. 
4, Woody, (dignosum), when ‘both valves are as 
hard as a nut-shell, and’do not burst. 
5. Mealy, (/arinosum), when the seed is surround: 
ed with a mealy substance. as in Hymenea curbaril. 
* Of the Silicule, there are some which have a double shell, 
the exterior softer and spongy, the interior harder, which con- 
tains the seed, inclosed in cells. These are called drupaceous 
Silicles, (sticule drupacee). But the kinds of silicle which 
never burst, are called baccate. Of'the first kind, Bunias, and 
of the second, Crambe, afford examples.
