104 TIIK NATUllALIST. 



splcant, Lastr(Ea spmulosa, and Eqidsetmii sylvaticum are particularly fine 

 here. On a common just out of this wood, Eanimculus Flammula is plen- 

 tiful ; I mention this, as this species is not very common in this neigh- 

 bourhood. Here I have since found the sweetly scented Spiranthcs au- 

 tumnalis in great abundance. A little further on is Lane End Common ; 

 here grows Scutellaria minor. Between Wycombe and Sheepridge, and 

 near the latter place, Mdilotus vulgaris grows in the clover-field mentioned 

 at p. 58, with Cuscuta europcea ; is this speeies generally known to infest 

 clover ? Here it certainly did so, the red stems clearly distinguishing it 

 from G. Trifolii. In the same field was a proliferous variety of Daucus 

 Carota, having small umbels growing out of the original head. 



An interesting walk is that from the Marlow Road station to Marlow. 

 Proceeding along the Buckinghamshire side of the river, I noticed Achillea 

 Ptarmica in small quantity ; it is not common in this district. On a piece 

 of waste ground, near* the Spade Oak Ferry, were Plantago Coronojms and 

 Erodiimi cicutarium ; and by the river a single plant of Sium latifoliuin. At 

 Marlow, this species and S. angustifolvum occur in some plenty by a ditch 

 in a meadow near the suspension bridge. In a field of saintfoin, near 

 Marlow, was a single plant of Delphinium Consolicla ; this has also been 

 found in the Rye, High Wycombe ; Sedum Telephium was observed in the 

 hedge. Crossing the Marlow bridge, I returned through the Bisham and 

 Quarry woods, along the Berkshire side of the river ; here LijsimacJiia 

 vulgaris grew in groves. About the Quarry, Monotropa Hypopitys was very 

 fine and abundant, with some dead stems of an OrcJds, which I thought 

 might be 0. militaris ; Epipactis media was plentiful here, and E. latifolia 

 appeared in small quantity. Emerging from the wood, I came on to Winter 

 Hill, where Asperula cynanchica grew in abundance. A ditch at the foot 

 of this hill was in one place comx3letely covered with Hydrocharis Morsus- 

 rancB, a beautiful plant, but a most difficult one to convey home in good 

 condition ; in other parts were Anacharls Alsinastrum, Sparganium natans, 

 S. simplex, Helosciadium immdatum, (EnantJie Phellandrium, (E. fishdosa, 

 and last, but not least, Utricularia vulgaris. The floating bladders which 

 support the flower-stems of this plant are very remarkable ; the yellow 

 blossoms are very beautiful, and bear a distant resemblance to those of 

 the garden Calceolaria. In a clover field, on the other side of the hedge, 

 Cuscuta Trifolii was so fine and abundant that it must have proved a 

 considerable nuisance to the owner of the crop. In one of the ponds, 

 at the foot of Winter Hill, were Si^m latifolium and Butomns umhellatus;
