capitatum, angustatum and angustatum minor. The fol- 

 lowing have been collected from various sources, the nomen- 

 clature being descriptive : — Marginatum, cristatum nanum, 

 crispum nanum, crispum cristatum: compactum, crispum 

 cristatum, sculpturatum nanum, ramo cristatum, muri- 

 catum, curioso filiferum, ramo marginatum nanum, rugosum 

 nanum, and several others on trial. None of these exceed 

 six inches in height, the majority being between twb and 

 four inches; all are thoroughbred. In A. f.f. there are 

 Congestum excurrens, c. minus glomeratum, c. grandi- 

 ceps, Kalothrix cristatum (Druery), Velutinum, seti- 

 gerum congestum, s. c. cristatum congestum minus, c. m. 

 cristatum, congestum minus fimbriatum, c. m. f. cristfettum, 

 and a few seedlings under trial of P. angulare, grandidens 

 nanum, congestum of Padley and Lyall, both simple and 

 crested, congestum densum, congestum, perserratum, 

 congestum, and what is, I believe, quite new in P. ang., a 

 perfect spirale, five inches high, with quite circular trun- 

 cate fronds, an inch in diameter, as stiff as a bottle brush. 

 There are but few Lastreas and no Polypodies. One which 

 was sent to me as a true dwarf very quickly changed its 

 character, and became of almost normal dimensions. 

 Doubtless many other dwarf forms exist, Blechnum sp. 

 crispissimum being a notable example, and I hope to make 

 additions from time to time, but judging from the number of 

 trials I have made, true dwarfs, whether amongst large or 

 small growing species, are not easy to raise or meet with.

THE ORIGIN OF THE NAMES "OAK 

 FERN" AND "BEECH FERN." 



The exact significance of these names is involved in 

 considerable obscurity. Sir J. E. Smith and Edward 

 Newman both comment upon them as singularly inappro-
