SCOLOPENDRIUM VULGARE. 



rather dwarf, handsome form. Branching at the base in 

 the stipes, and branching and re-branching two or three times 

 along the frond. A wide-spread very broad head. The 

 illustration is from Mr. Edwards' fronds. 



Proliferum, Wollaston. (Fig, 630.) — A singular monstrosity, 

 which was raised from spores by Mr. Wollaston, of Chiselhurst. 

 It is of the marginatum group, dwarf, scarcely three inches in 

 length, and usually the lamina only one inch long, and from 

 three to five eighths of an inch wide, mostly oblong, sometimes 

 cornute, profoundly and irregularly marginate; the excurrent 

 membrane so very much developed, that the frond appears as 

 if split in two edgewise on either side of the costa. The upper 

 surface of the frond irregularly verrucose. It bears no sori, 

 but on the surface of the frond are little bulbils, which ultimately 

 form small plants resembling the parent. Occasionally the fronds 

 are AvhoUy stipes and costa, without any leafy portion, and these 

 taper and are pointed like an awl. My thanks are due to Mr. 

 Elworthy, of Nettlecombe, for a plant.

Spirale, Moore. (Fig. 631.) — One of the crispum series, 

 found in Guernsey by Mr. J. James, of Van vert; and at 

 Nailsworth, Gloucestershire, by Mrs. Campbell. A singular 

 distinct form. Length of frond three to five inches, and 

 about an inch wide. The basal part rmdulate, becoming 

 twisted towards the apex in the manner of a corkscrew. My 

 thanks are due to Mr. P. Neill Eraser, of Cannon Mills Lodge, 

 Edinburgh, for a plant.
