Fig. 190. 



Interrupta, Moore. (Fig. 190.) — Found at Windermere, 

 by Mr. Clowes, and in the neighbourhood of Grange in 

 Furness, and Arnside, Morecambe Bay, by Mr. Monkman and 

 Mr. Crossfield. A constant variety. Very irregular in character, 

 and abnormal-looking. Most of the pinnules very much 

 narrowed, and are changed from the normal character, either 

 forming brief inciso-serrate lobes along the rachis, or are 

 larger and laciniate. The fronds have a tendency to divide at 

 the apex. My thanks are due to Mr. Clowes, of Windermere, 

 and to Messrs. Stansfield, of Todmorden, for fronds. 



Cristata-angustata, Moore. (Plate XXXI — A.) — A very 

 handsome and distinct form, differing from cristata, in the 

 narrowness of the fronds, in being only pinnate, and the 

 pinnules all confluent, so that the margins of the pinnae are 

 merely shallowly lobed. A form of Lastrea propinqiia. The 

 present variety is exceedingly distinct from the beautiful multifid 

 variety known as cristata. The frond is remarkably narrow, 

 nearly linear, being only from an inch to an inch and a half 

 in width. The pinnge are crested except the upper portion of 

 the frond, whilst the extreme point is tasseled. The stem is 

 covered with reddish brown scales. Length of frond from 

 twelve to eighteen inches. This variety was raised from spores 

 by Mr. R, Sim, of Foot's Cray, and has proved quite constant. 

 Colour a rich deep green. My thanks are due to Mr. Edwin 

 Cooling, of Milcash Nursery, Derby, for plants of this fern, 

 and to Mr. R. Sim, of Foot's Cray, and to Messrs. Stansfield, of 

 Todmorden, for fronds. Only pinnate, the pinnules being all
