described in nuci, very briefly in the meeting reports of the 
Physioloprical (?.E.D.) Society, which you have in St. Lonis.. 
3) ■A.Braim,who also visited here 2 years ago.thought the plant! was 
an ArceuthobiiHiivrather than a Gaetacea. I canit apcree with the opi- 
nlon^, As you have worked specially with ArceiJithobium-,1' want to ask 
you for your judgement,. I know only Are, . oxy (oxycidei 1/) 
but have only male specimens, According to Hooker Illustration ^ 
(Fl. borealis americana) Arceuthobium oxycidei and probably the re- 
latives do not fit for 2 reasons) / Satzia has a perigon, which on top 
is entirely fullrimed (i.e. **entire*' E.D.) and not 2-lipped:^ as withh 
Arceuthobiumv 2) ' Satzia has on the branch portions, which do not

should come much into consideration here». I have several hundredi^ 
polished pieces of such timbers of the diluviim^ , , most of them are 
Pines. -It would be most desirable for me to have timbers of ameri- 
can»^ trees for coraparison. .1 would gladly pay several hund red Mark-- 
V 1 Thr = 3 Mark),, 200 - 300 Mark for a good collect Ion-, which has 
been correctly identif ied by you, You could determine the price«. 
Cones of conifers, flowers, leafstems would be very welcome; specially^ 
flowers with pollen, which is found abundandly in amber. Of course,, 
the pollen of Pinus and Picea^ species are related to each other,. 
Special thank for Njrmphaea flava - I received ^ p«»pfe- (rhy - 
zomes ? E.D.) from Cambridge. Three, the best,were frozen on the
