H 

 Reseda lufea, L. Ballast-heaps, Catdown quarries, Plymouth. As 



this plant is not met with elsewhere in this district, it perhaps scarcely 



deserves a place in this list, being undoubtedly an alien. It has, 



however, occupied its present habitat for the past six years under my 



own observation ; how long before, I know not. 



Koniga ma?'ilima, R. Br. On rocks near the sea, Plymouth and 

 vicinity ; frequent. 



Diplotaxis muralis, De C. Catdown, Mutley. From the syno- 

 nyms employed, this plant appears to be comprehended under Sinapis 

 tenuifolia by the author of the ' Flora Devoniensis.' It is, however, a 

 distinct plant. 



Helleborus fcelidus, L. Manadon, near Plymouth. 



Ranunculus Lenormandi, Sch. Frequent in this district. 



Appended are additional habitats for three or four of the plants 

 named in Mr. Hore's list. Those to which an asterisk is prefixed 

 rank therein as Cornish plants. Their appearance in this county as 

 well is therefore the more worthy of note. 



*Briza minor, L. Catdown, Plymouth, 1850. 



Tragopogon porrifolius, L. Grass-plot in front of Devonshire Ter- 

 race, Plymouth. 



*Trifolium ornithopodioides, L. Cann quarries, Bickleigh Vale, 

 Miss Edmonds, 1849. It was collected this year by Mr. F. H. 

 Goulding. 



* Reseda fruticulosa, L., was found at Hooe, near Plymouth, in 

 1844, by Mr. G. Bartlett. I have not heard of its having been met 

 with since.
