Skipwith Common, 4th July, 1903 ; legit J.F.R. It was one of the 

 Top. Bot. omissions from Flora E.R. Yorks.

Besides the above, which should be added to the 1035 

 species recorded in the East Riding Flora, many additional 

 stations of the less common plants have been discovered, 

 notably on the boulder clay under-cliffs near Primrose Valley 

 and other places on the shores of Filey Bay, the sandy tract 

 called Hotham Carrs to the west of North Cave, and on the 

 old and favourite ground of Skipwith Common, near Selby. 



None of the Dock Waste or Cornfield aliens are included 

 in the above, but it may be stated that already between fifty 

 and sixty must be added to the already copious list in the 

 "Flora," p. 47. These additions to the "alien" list have 

 all been made since its publication, and were determined, as 

 previous examples were, by the most courteous and able 

 Chief of the Botanical Gardens and Afforestation Department, 

 Hong Kong, Mr. S. T. Dunn, B.Sc, late of the Royal 

 Gardens, Kew, who characterised our last batch, gathered 

 chiefly on the West Dock Reservation, as "a particularly 

 interesting set of plants."
