415 
Lycopodium clavatum. 
Hook., Brit. Flo ., Edit. 8, p. 457 ; Edit. 4, p. 891. 
Francis’ Ferns , p. 57, pi. 6, fig. 1. 
With. J9o£. (MacGilliv.), p. 387. 
Spikes stalked, mostly double; leaves narrow, entire, and hair-pointed. Scales 
ovate, eroso-dentate. 
The stems of this species grow a considerable length, and are beautifully 
branched. I have one specimen about twenty-one inches long, which in grace 
and regularity far surpasses all I have hitherto seen. 
Lycopodium annotinum. 
Hook., Brit. Flo ., Edit. 3, p. 457 ; Edit. 4-, p. 391. 
Francis’ Ferns, p. 58, pi. 5, fig. 2. 
With., Bot. (MacGilliv.), p. 387. 
Spike solitary, sessile; leaves linear-lanceolate, more or less serrated, in about 
five rows. 
Scales broadly ovate, short. 
Mr. Francis, in his little work, mentions Sir J. E. Smith’s statement,— a That 
the scales of the spikes of one season, falling off, the stem thus left naked gives 
rise the following season to leaves, but these not being so numerous as the other 
parts of the plant, the stem acquires an interrupted habit.” He then states that 
he cannot reconcile this with the appearance of his specimens, neither can I with 
the one in my possession, but should consider actual observation of living plants 
necessary before giving an opinion; I mention it only from information. 
Lycopodium inundatum . 
Hook., Brit . Flo., Edit. 3, p. 457 ; Edit. 4, p. 391. 
Francis’ Ferns, p. 57, pi. 5, fig. <3* 
With., Bot. (MacGilliv.), p. 387- 
Branches simple, with few leaves, which are narrow, and acute. Scales like the 
leaves, but more or less dilated at the base. 
Lycopodium selaginoides. 
Hook., Brit. Flo., Edit. 3, p. 457; Edit. 4, p. 392. 
Francis’ Ferns, p. 59, pi. 5, fig. 4. 
With. (MacGilliv.), p. 387. 
I know not how much this species varies in size and appearance, having only 
seen about five or six specimens,from Seaforth Common, near Liverpool, measuring
