178 ALIEN FLORA OF BRITAIN 



[Stratiotes aloides, L. It has been recorded in many 

 parts of England, in ditches, canals, and backwaters 

 of rivers, and as it occurs on the Continent in 

 similar situations, there is no reason to doubt its 

 indigenous state. In Scotland and Ireland, however, 

 there can be little doubt that all the stations recorded 

 for the species are due to introduction, though it now 

 appears quite naturalised in them.] 



IRIDACE^. 



Crocus aureus, Sibth. and Sm. A native of meadows 

 in South-East Europe. Recorded as a garden relic in 

 a few situations in England. 



Crocus biflorus, Mill, Native of meadows in Southern 

 Europe. Once or twice observed in Suffolk in a semi- 

 naturalised state about old parks and gardens. 



Crocus nudiflorus, Sm. Native in meadows of 

 Southern Europe and the Orient. Absent, at least 

 as a native, in Northern France, Belgium, and 

 Holland. In England it appears to be naturalised 

 in meadows in the midland counties, near gardens 

 and villages. 



Crocus sativus, L. Several forms are said to be wild 

 in the mountains from Italy to Kurdestan. It has long 

 been cultivated in England, and has been observed 

 as an established plant in meadows near places where 

 it has been cultivated.
