122 LULEAX LVPLAND. 



Stor Luleå, running from the alps in Nör- 

 battra. 



JiiIH 30. 



On examinnig the cultivated Hop [llu- 

 mulus Lupulus), I found the structure of 

 the female as follows. Calyx consisting of 

 an universal involucrum of four leaves, and 

 a partial one, likewise of four ovate leaves, 

 containing eight florets, each of which has 

 an ovate spatha, of a very large size with 

 respect to the rudiments of the fruit. Pe- 

 tals none. Pistils two, horn-like. Stigmas 

 acute. Seed-vessel none, the base of the 

 spatha enclosing the seed, which is solitary. 



The shore of the river Lulea produced, 

 in excessive abundance, the \yater Sedum 

 {Tlllaa aquatica) ; likewise the Aquatic 

 Dwarf Plantain {Limosella aquatica). The 

 Spiked Water-grass, with a bent stem, here 

 grew above other plants, twisting its leaves 

 round them, like a sort of bindweed. (J/o-
