§ 7. Systematic Position. 
This paragraph is not for the purpose of deciding upon the 
systematic position of the Chare, for that has been already spoken 
of ; I merely wish to notice a few special points. 
It is evident from the above, that the formation of the fruit of 
the Chare cannot be considered as a high grade of development. 
To what other cryptogamic family is it best comparable? I do 
not hesitate to state, the Alge. Kiitzing, in his ‘ Phycologia 
Generalis,’ has unconditionally referred them to this position, 
placmg them near Lemania. We must here bear in mind the 
structure of the fruit before all things, and although we are but 
little acquainted with the fruit of those Alge which are nearest 
related to the Chara im habit, in examining the latter I at the 
same time met with another of the Alge in which the most re- 
markable analogies to the fruit of the Chare existed. I allude 
to Chetophora tuberculosa. In the ‘ Flora,’ 1842, no. 33, I have 
published a small treatise on it, which unfortunately still remains 
very imperfect. The main point is, that in it the analogues to the 
anthers of the Chare may be positively found. They are red glo- 
bules, formed in a much more simple manner than the anthers 
of Chara. They also lie close to the fruit, which is also nothing 
more than metamorphosed buds. Kiitzing, who quotes my paper 
in the essay above mentioned, p. 325, denies any analogue of 
the anthers either of Phanerogamia or Cryptogamia, and asserts 
that the above red globules are nothing more than the more 
highly developed fruit! Having lately carefully moistened and 
again examined my dried specimens, by which they were not found 
altered in the least, I must most decidedly protest against this 
statement! When I look at the two cells of the anthers and fruit 
of Chara represented in fig. 27, I find, as it appears to me, the 
lowermost red, the contents of the upper being green,—a similar 
formation to the two organs in Chetophora. Unfortunately not 
having enough specimens, I cannot make any more remarks upon 
them than what I have already stated in my history of the de- 
velopment of Chetophora. I therefore strongly recommend those 
fortunate persons, who should again meet with them, to examine 
them most accurately and to compare them with the organs of 
fructification of Chara. As far as I know, no one has noticed 
the above red globules. However, as long as this remains so, we 
must regard the Chare as a familia incerte sedis, but must place 
them near the Ale. :
