are more inclined to roundish, and are only slightly crenate: the 

 stem upright, undivided, about a foot high: the stem-leaves two or 

 three pairs, smooth, ternate, on short petioles: leaflets confluent at 

 the base, lanceolate, acute, unequally subserrate, the middle one 

 larger than the others: they vary much, being gash-serrate, crenate, 

 or even quite entire; the uppermost are sometimes lanceolate-linear 

 and quite entire, sometimes pinnate with five leaflets: the flowers 

 numerous, white, in loose corymbs. It is a native of the Alps of 

 Switzerland, flowering here from March to May. 



The sixth species agrees in stature and habit with the preceding; 

 but this is more tufted, and has the root commonly creeping hori- 

 zontally, more divided, and not smelling so strongly : all the leaves 

 are acute, unequally serrate or toothed and smooth; the root-leaves 

 are on long petioles, and more or less attenuated at the base towards 

 the petiole: the stem-leaves vary in number, are on short petioles, 

 and rather oblong: the stem is upright, simple, a foot or eighteen 

 inches high: the flowers in a corymb, whitish or purplish. It is a 

 native of Switzerland, Austria, Sec. flowering here in June and July. 



The seventh species has a perennial root, black, oblique, with 

 long fibres, smelling very strong, aromatic, caulescent at top and 

 scaly with the remains of the deciduous leaves ; it is often in tufts 

 with an upright stem, four or five inches high: all the leaves are 

 quite entire and obtuse; the root-leaves subovate, and attenuated 

 into the petiole at the base; stem-leaves two, opposite, linear and 

 sessile, about the middle of the stem, but there are sometimes none: 

 the stem slender, simple, terminated by a few small whitish flowers 

 in a corymb. It is found in Switzerland, flowering in June. 



The eighth species has roots perennial, and tuberous, by which 

 it is easily distinguished. It is a native of the south of Europe, 

 flowering in May and June. 



There is a variety with the roots in the form of an olive. 



The ninth species has a perennial fibrous root, from which come 

 out many heart-shaped leaves, on petioles more than a foot in 

 length; they are four inches over each way, bluntly serrate, smooth, 

 and of a bright green on their upper surface, but pale and a little
