io8 FERN GROWING 



Paulovna (Fig. 43). A very lax Victorice^^k.^ form with 

 evident peculiarities of lineare Victorice and Delleseriotdes ; 

 the stem is naked, and all the divisions of the capitate apex 

 are linear ; sori marginal. 



Czarina. Somewhat similar, but with an enormous head, 

 which is pendent. 



EXPERIMENT NO. XXI. 



In 1890 the following varieties of Scolopendrium vulgare 

 were sown together — kraspedoumenon (a variety having 

 marginal sori), lineare (an exceedingly narrow form having 

 the stipes broader than the leafy portion), and keratoides (a 

 branched variety). Many of the seedlings are distinct varieties. 

 Arline is the best ; it is 9 inches long, and only one-eighth 

 of an inch broad. At 3 inches from the apex the frond expands 

 into a much ramose head, which is 3 inches long and 6 inches 

 wide, with all.the divisions linear ; and the sori, which is copious 

 both on and below the capitate head, is marginal. 



EXPERIMENT NO. XXII. 



There are some very curious varieties raised from this 1890 

 mixture of Scolopendrium vulgare. The varieties sown together 

 are undulatum, spirale, muricatum, comutum, a.nd pera/erens. 



Attention may be called to Puck, which is undulate, muricate, 

 and has a horn half-an-inch long at the apex of the frond, 

 which is muricate and club-like. Below the horn is a muri- 

 cate rosette, the divisions of which are at right angles to the 

 horn. The length of the frond is 4I inches, and the width 

 six-tenths of an inch. The stipes is 2f inches long. There is 

 evidence of the combination of all five parents in this variety. 



A second variety (Argia) has an arcuate horn i| inch in 

 length rising from a peraferent muricate rosette which is 

 seven-tenths of an inch in diameter. The horn is not 

 muricate. The frond is a naked stipes, except the rosette.
