another time. 
The finding of the Drilling I.macrospora is ofeourse really 
nice - all three with different labelslt 
Of Durian I had become a little suspicicthous myself,but un - 
and correspondent; it 1s striking that Durian never answered after 
my letter must have gotten to him months ago. 
Did you bother with Juncus during the past year and resear - 
ched about the one and only multi-flowered rush, and do you stick to 
your previous idea ? 
I did receive: the small shipment of Anticharis and Phyllo - 
elossum; also from Leipzier the catalozue of the Matthews Library. 
Did you contact Gottsche concerringe the Hepatica from Califor-

Your Isoetes Boottil has quite the same spores as Braunii and 
the leaves of numlicata, a few stomata, a strong velum ligsu. on both; 
I think it is bound to be a form of echinospors; I believe that the 
eircle of forms of our species is much larger that that of the euro- 
paeans and that may seduce you over there. However „ our industrious 
explorers, namely Boott and also Canby will search during this year 
on the old ( 13 years) Bi vLinton, 50 determine IT possible, 
My seedlines of I. Engselmanni survived the entire winter well. 
The old plant remained quite green in a cold room where it froze oc- 
casionally. Now, I fear however, that all has been lost. Did i send 
you once dried plantlets after they had germinated ? 
Did I ever report about the Isotes from Canada ? I received 
2 species from a collector fpom North of Lake Ontario: _I. Braunii,
