stoke, and on the sea-bank near Worsewell. Newton Ferrers. 

 Yealmpton, in a pasture. A single plant near Lutton, by the 

 road to Cornwood, 1874. 

 YI. Mothecombe. 



This species chooses for the most part warm spots, and by far the larger 

 number of its stations are in the neighbourhood of the coast or near tidal 

 waters. At Crown Hill, however, in District in., it occurs at an elevation 

 of 425 feet. 



Particulars concerning several peculiar plants, apparently hybrids be- 

 tween this species and two or three of the others, have appeared in some 

 of the Reports of the Botanical Exchange Cluh. One from near Torpoint 

 (District ii.), and another from a pasture at Tothill (iv.). Dr. Boswell 

 considers to be between it and R. conglomeratus. They were collected 

 in 1873. A few plants, very similar, I found at Swilly (District in.), in 

 1879, growing with the presumed parents and with R. nemorosus and R. 

 Friesii. (See Boswell, in Bot. Ex. Club Reps. 1872-74, 34, 35 ; 1876, 31. 



Another Dock, intermediate between pidcher and riqjestris, I found in 

 two spots on the shore of ^^'hitsand Bay, near Rame Head (District n.), 

 in Jidy, 1876, growing with the latter ; pulcher occurring on the upper 

 part of the cliffs and in the old pasture land immediately above. There 

 were several roots, and many specimens have been distributed through the 

 Botanical Exchange Club. In the Rej^ort of this Club for 1877-78 there 

 is mentioned a supposed hybrid between pulcher and obtusifolius, ob- 

 tained from " Waste ground, West Head (Whitsand Bay), near the sea, 

 July 12, 1878." It was collected and sent to the Club by the Rev. 

 Augustin Ley. 



604. B. obtusifolius, ^?<c^. Broad-leaved Dock. 



Native ; in marshes, moist fields, orchards, and damp waste 



places. Very common. June, July. Area general. 



The species that supplies the leaves often wrapped around butter 



brought to Plymouth ^Market. So far as I am aware it is only var. a. 



Friesii that occurs m the area. Sometimes seen in damp plots of ground 



in the town of Plymouth. 



605. R. pratensis, M. and K. Meadow Dock. 



Native ; in waste places, by roadsides, m pastures and marshes. 



Common, and widely diffused. June to August. 



c. I. Hessenford. Port Wrinkle. Downderry. Between Saltash and 



Notter Bridge. Between Stoketon and Moditon Mill. Between 



Landrake and Tideford. Between Filbridge and Wooton Cross. 



Pniaton. Between Tideford Cross and Killa. 



II. Rame. Near Anderton. St. Johns. Torpoint. Antony. Calstock.
