1859.] EXTRACTS FROM CORRESPONDENCE. Ill 



which I have noticed the two last years growing plentifully in a 

 field in this neighbourhood ; and I should be much obliged if the 

 Editor of the ' Phytologist' would kindly inform me to what 

 species of Trifolium it is to be referred^ as it does not appear to 

 me to agree with any of those described in the ordinary works 

 on English Botany. Its flowers are of a pale rose-colour^ and 

 before they are fully expanded, are reflexed in the same way as I 

 understand those of T. resupinatum to be. It extends over almost 

 the whole of one field, and if it should prove a foreigner, has 

 probably been introduced with seed, as I do not observe it in any 

 neighbouring fields. The field has been scarified and burnt this 

 autumn before ploughing, so I cannot say if it will appear again. 

 The specimens were gathered, the larger ones in September, 

 1857, after a crop of barley had been reaped, the smaller ones 

 in September, 1858, the field having been "fed off^^ with sheep 

 throughout the summer.^ 



Crocus vernus. 



Barnston Elton, Nottingham, March 3, 1859. 

 I sent off by post yesterday a small tin with a number of the 

 Nottingham Crocus vernus, which I hope you have received. 

 Owing to the forwardness of the season, they are now in full 

 bloom, and the meadows are covered with them in the greatest 

 profusion. In greater or less quantities, they extend over a space, 

 I should say, of more than a hundred acres ; and I cannot think 

 that any one who saw them in this locality would doubt their 

 being truly wild. In the season, you may see them lying about 

 in Nottingham streets in all directions, as all the children in the 

 place turn out and gather them. The white one I sent was the 

 only one I have seen. R. E. C. 



Sisymbrium pannonicum. 

 By H. Fisher, Liverpool. 

 About the month of May, 1858, I first observed a plant, then 



* The specimens were duly received, and it is conjectured that they may belong 

 to the species T. elegans, which has only recently been observed at Wandsworth, 

 near the Steam-boat Pier. — Ed.
