674 ASARUM. [CLASS XI. ORDER I. 



flowered plants have been by some authors made distinct species, the 

 red flowering plants having the petals with deeper, narrower, and more 

 spreading lobes, and the capsules rounder, with the valves recurved, 

 while the white flowered one has broader less spreading lobes to the 

 petals, ovale conate capsules, and the valves of erect teeth. We do 

 not, however, find this character sufficiently constant, the petals both 

 of the red and white variety vary considerably in width, the shape of 

 the capsule is not constantly the same, and the teeth of the white 

 variety are as frequently reflexed as erect. 



Both these varieties are occasionally cultivated in gardens, and fre- 

 quently become double, and very ornamental ; but that the species 

 mentioned above are liable, unless care is taken of them, to return to 

 the single state.
