SYSTEMATICAL NOTES. 



About the affinity of the several genera and species we have 

 already said something under those genera and species of which 

 the affinity had something peculiar or needed special explanation. 

 Therefore we need not add much. Yet stress might be laid on 

 the following where there may be some indication about questions, 

 which are not clear and should be examined afterwards. 



Geunsia, a genus of which for a long time only one species: 

 G. farinosa, has been known, appears to be a rather large one, 

 now being composed of 13 species. We discussed in details its 

 close affinity with Callicarpa, to which it is closely allied and 

 enumerated the distinctive features by which it is different fromv 

 that genus. We got the impression that Geunsia is a variable 

 genus since we found e.g. 4- and 5-merous flowers on the same 

 plant. It is apparently also a genus with primitive characteristics, 

 such as the alternate leaves and the often 5-merous and regular 

 flowers. We may consider the opposite leaves and the often 

 4-merous flowers as a transition to Callicarpa: and the fact that 

 there are on the same plant (or even inflorescence) 4- and 

 5-merous flowers and that the alternate leaves sometimes are 

 nearly opposite whilst the general habit is that of a Callicarpa, 

 may indicate that Geunsia is a genus in a mutation-period, and 

 that into two directions, giving in the one hand the pure 

 Callicarpa-toim, on the other 6— 7-merous forms which remain 

 true Geunsia s, the original form being 5-merous and with alternate 

 leaves. Another differentiation within the genus is in the developing 

 of pseudo- whorls (of 3 or 4 leaves). 



Callicarpa is also a genus with rather primitive features. Its 

 flowers are entirely regular, and it is a rather uniform group of 

 plants, in which it is often very difficult to fix the limit of the 

 several species mutually, this being indistinct.
