184 LINN/EAN NATURAL SYSTEM. 



They have also a bitter flavour, and scarcely any of the order arr 

 odoriferous, except melianthns, which is extremely foetid. The plants 

 are smooth and unarmed; a few of them climbing by means of ten- 

 dril*. The leaves are alternate in all, except in calceolaria, and 

 many bear stipules. Their mode of flowering is spiked, racemose, or 

 solitary, their stalk naked or leafy, different in different species. 

 The calyx is of two leaves, except in pinguicula, where it is only 

 cloven ; and melianthns, where it consists of four leaves. 



ORDER XXV PUTAMINE*. 



26. This order consists of a few genera of plants 

 allied in habit, whose fruit is covered with a strong 

 rind or hard woody shell. Cleome, crataeva or garlic- 

 pear, capparis or caper-tree, &c. 



ORDER XXVt. MULTISILIQU. 



27. Containing an arrangement of plants with more 

 seed-vessels than one, such are those of the genera 

 paeonia or peony, aquilegia or columbine, aconitum or 

 aronite, delphinium or larkspur, helleborns or hellebore, 

 anemone, ranunculus, and several more. 



Most of the order, with a few exceptions, are of European growth, 

 acrid taste, and generally of a disagreeable odour ; none esculent, 

 and most poisonous ; rarely arboraceous or shrubby, except such 

 species of climatis as climb trees. The roots are fibrous, sometimes 

 tuberous ; leaves often many-cleft or compound, bat in a few in- 

 stances simple ; all alternate, except in the climatis integrifolia. 

 There are no stipules, spines, or prickles. Flowers never monope- 

 talous ; stamens for the most part more than eight. Fruit in some 

 capsular, in others single-seeded.
