mination of the 3 lobes

Ya n/4 2 SLeA - 
4. shows the exploded spore sühTakzthwing with a green shoot 
within a whitish pre-germ,formed by a coarse cell-tissue. The 
leaves of the germ (first one) push throush the pre-germ,the skin 
of the germ is shed and after that also the pr&zerm. I do not 
know if the pre-germ is being torn into two lobes, but that is 
possible, 
The young plants form a 2-lobed tuber quite soon, as I ob- 
serve on the found, specimens, but I cannot determine with certainty 
if the first leaves turn in the direction of the 2 lobes of the 
tuberbr if they alternate with them, which to know is impor- 
tant.Thus I illustrated for you all kinds of points, which can 
be examined better on the living material than on the dried one, 
and I ask you to communicate your observations to me in due time.. 
I ask you to provide me with a substantial number of dried specimens 
so that I may tell strargers about this interesting plant and con- 
ae myself the investigation, specimens collected during the 
various seasons.Also it may be perhaps successful to set tubers 
which have been collected at the proper time, here.. 
In the near future I shall send to Dr. Engelman for you’ several 
specimens of various europaean Isoetes species as a small sien of 
my eratitude. 
Respectfully and with friendly rezards your obedient 
A.Braun Professor
