Note on Lastrea uliginosa. By the Rev. W. T. Bree, M.A. 



In consequence of the notice relating to Lastrea uliginosa on the 

 cover of the August number of the ' Phytologist,' I have lately pro- 

 cured, through the kindness of a friend, a living plant of that fern, 

 from Mr. Kennedy, in fine condition and fructification ; and I feel no 

 hesitation whatever in saying at once that it is not Lastrea Filix-mas, 

 rigida, or cristata ! The fern is familiar to me as what I have long 

 been accustomed to distinguish by the name of Aspidium spinulosum, 

 i. e., Lastrea spinosa of Newman. The species is not uncommon in 

 this neighbourhood in moist woods and bogs ; but here with us it is 

 usually of a much paler green. The darker colour of Mr. Kennedy's 

 plant may possibly be owing to cultivation, soil, situation, &c. In 

 Coleshill Bog, where the fern occurs in exposed situations, quite un- 

 sheltered by trees or bushes, the fronds are of a very light green, or 

 rather of a yellow colour. I am decidedly of opinion that Lastrea 

 uliginosa, which I admit would be an appropriate name for the plant, 

 cannot be considered'as a distinct species, and that it is only one of 

 the phases of the somewhat variable Lastrea spinosa, or, as it is, I be- 

 lieve, more generally called, spinulosa.
