INTRODUCTION. 
17 
petals only and 5 stamens. That was even a 
deviation from the family ! 
2. I have met with a Tecoma bearing a ca- 
psule with 3 valves, the generic character is 
bivalve. 
3. Asters and Solidagos with the ligules 
mixt with the florets, forming a kind of peloric 
genus which I have called Mictanthes. 
4. The Aster discoidens of Elliot or my 
genus Anactis , has no rays, it must have been 
a deviated genus like Pclipta from Verbesina. 
I have met some Asters with the rays so short- 
ened as to be almost invisible. 
5. My G. Gononcus has two sorts of flowers 
and seeds on the same plant, uniting the char- 
racters of Polygonun and Persicaria . 
6. My G. Styrandra appears to have" origi- 
nated once from Convallaria or rather Majan - 
themum , just like Paris from Trillium. 
7. Many monoical and dioical plants return 
to Polygamy and hermaphroditism. This is the 
case with some of our Vines, Vitis , M or us, Ur - 
tica , Callitriche , &c. 
8. Nothing more common than monstruous 
deviations by addition or deficiency of parts, 
which are as many links of generic varia- 
tions. 
Of all the European Floras, that in which 
generic and specific deviations are most expli- 
citly stated and best detailed, is the Flora Li- 
thuanica of Gilibert, where many similar ano- 
malies may be noticed. 
Therefore the result will be that our species 
and genera are not quite permanent as suppos- 
ed, but are gradually producing deviations of 
forms ; when these are floral they are of course
