 Camelina dentata, Peru.

Alien. Found almost tlu'oughout Britain, where flax is 

 cultivated ; and along with which the seeds of the Cameli- 

 na are doubtless sown. It occurs also sometimes on bal- 

 last heaps ; as, for example, those of Tyne, from which 

 Mr. Storey has sent a specunen to my herbarium. Cannot 

 be deemed a permanent weed in any pait of Britain, as far 

 as known to me. Mr. Babmgton says that C. dentata oc- 

 curs along with C. sativa, and probably enough some of 

 the reported localities, in which the latter has been suppos- 

 ed found, might have been assigned to C. dentata. Some 

 botanists, not without a show of reason, hold the alleged 

 two species to be truly one only. Yorkshire is the only 

 county from which I have seen the C. dentata expressly 

 reported. 



81. KONIGA MARITIMA, B). 



Area (1 2 3 4 5 6 * * ^). ***** 15). 



Alien. It is curious that this plant, which scarcely 

 maintains ground anywhere, even in the south of England, 

 should have been originally admitted as a British plant on 

 the faith of a locality, doubtless accidental and temporaiy, 

 so far north as Aberdeen. Some few more locahties, addi- 

 tional to those collected into the New Guide, have been 

 recently published ; but they are scarce worth mentioning. 

 One of these, " wall at Newlyn, Mount's Bay," is probably 

 the same spot on which the species was observed by myself
