20 FERN GROWING 



4, 5, and 6, page 19),* and in the variegated forms of 

 Scolopendrium vulgare. 



"As examples we have selected experiments made with 

 varieties of Asplenium, section Athyrium, and Scolopendrium 

 from Mr. Lowe's series, and some made with varieties of 

 Aspidium, section Polystichum, from Colonel Jones's series. 

 We might have given several hundred examples, but a few of 

 each is ample illustration. 



"Example i. Athyrium. 



"The following varieties were sown together: — VictoricB, 

 multifidum, Jonesii, Craigii, uncum., Harrises, cruciatum, pro- 

 teoides, tortile, rejiexum, laciniatum, and grammicon. 



"The result has been several hundred intermediate forms, 

 some very interesting. 



"Example 2. Scolopendrium. 



"In this experiment the varieties were crispum (rarely 

 fertile), Victories, muricatum, marginatum,, undulcCtum., digitatum, 

 ramo-cristatum, laceratum, and a variegated crispum. 



" The result has been various intermediate forms, a 

 number of which are variegated ; for instance, the variega- 

 tion in the crispum has passed into a crested form, the colour 

 as well as the shape being altered. 



"Example 3. Polystichum. 



"The attempt was made to transfer the polydactylous 

 character of certain forms of P. angulare to other forms of 

 the same species which preserved the normal outline and 

 distinct individuality but were not polydactylous.
