was nothing otherthan Gringo( Horsehair) which name was given to all 

 Stachseiden. To that he noted that they stuck to the grasses(Caries, Cyperi, Leersia etc) 

 whereas not a Single Polygonum plant could be found. This response also takes care 

 ofyour question No.2 ( On what species of P. does it grow; on what other plants). I 

 found italways next to P. hydrocipher and parsicaha; it did spread out from these onto 

 the Caries and Leersia and Sparganien which also grew there.- Ad No.3. Never did I 

 See them together with another Cuscuta. 



I must confess that on the whole the characteristics I was informed to be 

 characteristic ofthe true C. polygonorum look different from mine; but I have as yet to 

 find striking, specific differences. The main ones depend, I believe, on the degree of 

 nourishment, and because I have found in the rieh soll exceedingly luxuriously growing 

 Vegetation every day, I am less inclined to put any value on such differences without 

 more^mportant characteristics. 



The considerable distance between the locations does not disturb me either 

 when I think of Xeranthemum friaidum which grows both in Armenien and the highest 

 mountains of Caspia(!). Fimbristviis sauarrofusa=sauarrosa (Vahl Enum 11.289) from 

 South America grows in season in a swamp in Toscana, and was seen there already by
