120 LINNJ.AN ARTIFICIAL SYSTEM. 



1. Siliculosa ; from the Latin silicuta, a little pod. 



2. Siliquosa ; from the Latin tilicula, a long pod. 



21. In the classes monadelphia, diadelpbia, poly- 

 adelphia, and gynandria, the orders are taken from the 

 number of the stamens. 



Monandria, diandria, triandria and so on, according to the num- 

 ber of stamens. 



22. In the nineteenth class, syngenesia, the orders 

 are taken from the structure of the flower. 



1. Polygamia aequalis ; the first from polus many, and no-inns nni - 

 ons ; the second aqualis equal ; meaning that each flower is equally 

 possessed of stamens and pistils. 



2. Polygamia superflua ; the first from pnlut many, and namns, 

 onions; the second tuperflua, superfluous ; meaning that the florets 

 in the disk being perfect, produce seed, and those in the ray or cir- 

 cumference (which are furnished with pistils only), are superfluous, 

 as the former were sufficient to continue the species. 



3. Polygamia frnstranea; the first from polus many, and gamot 

 unions ; the second fruttranea needless ; because the florets in the 

 ray being neuter, their existence seems useless. 



4. Polygamia necessaria; the first from polus many, and gamos 

 unions ; the second neressaria necessary ; because the florets in the 

 disk have stamens only, and in the ray pistils only, so that, if those 

 in the disk were absent, there would be no seed, hence the neces- 

 sity of the pistils in the ray. 



6. Polygamia segregata; the first from point many, and gamos 

 unions ; the second seyregata separate ; because the florets are all 

 equal, that is perfect, as with the order polygamia tequalis, but sepa- 

 rate by baring a calyx to each Jtoner, which separates the florets 

 individually. 



23. The classes monrecia and dioecia, take their 

 orders from the number and other peculiarities of the 

 stamen, and are named after the classes.
