added with hesitation. Tancccium of Swartz, and Possira 

 of Aublet, which last is Rittera of Schreber, are subjoined 

 by Giseke. 



Order 26. Multisiliqu^e. This consists of four sec- 

 tions. In the first are Pceonia, Aquilegia, Aco?iititm and 

 Delphinium, to which Linnaeus, after much diversity of 

 opinion, finally determined to add Cimicifuga and Actcea. 

 The second contains Dictamnus, Rut a and Peganum: the 

 third Nigella, Garidella, Isopyrum, Trollius, Helleborus, 

 Caltha, Ranunculus, Myosurus and Adonis: and the fourth 

 Anemone, Atragene, Clematis, and Thalictrum. "Most of 

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

 rarely arboreous or shrubby, except such species of Cle- 

 matis as climb trees. The roots are fibrous, sometimes 

 tuberous. Leaves often many-cleft, or compound ; but 

 in a few instances simple; all alternate, except in Clema- 

 tis integrifolia. There are no stipulas, spines, nor prickles. 

 One or two kinds of Clematis bear tendrils. Flowers in 

 no case monopetalous. Stamens always more than eight, 

 except in the second section. Fruit in some capsular, in 

 some single-seeded. An acrid taste prevails through the 

 whole. Their odour is disagreeable, almost universally, 

 so that none is esculent, and many, if not all, are poison- 

 ous, though there is no milky plant among the whole, nor 

 any one with a twining stem." Linnseus remarks, that 

 "a calyx is very rarely present, and when it occurs, ma- 

 nifestly originates from the leaves;" but this is not ap- 

 plicable to Ranunculus and its nearest relations, nor to 

 any genus in the second section ; that section indeed 

 being a most distinct order of itself, called by Jussieu 

 Rutacecz, but not well defined by him. 



Order 27. Riiceade/e. The poppy tribe. No remark 

 on this order is found in the lectures of Linnseus, but he 

 has made some manuscript notes. He wished to remove 

 it next to the 24th and to place its genera thus, Argemone, 

 Chelidoniuni, Papaver, Podophyllum, Sanguinaria and 

 Bocconia. Sanguinaria, he observes, has the flower of
