SuB-PLUMOSUM, IVullasioH. (Fig. 143.) — A very pretty form, 

 found ill Devonshire by the He v. C. PatUey, of Bulwell Hall, 

 and had previously, I believe, been found by Mr. G. B. Wol- 

 laston, of Chiselhurst. Fronds bipiniiate, twelve to fifteen inehes 

 in length, broadest in the centre; slender, delicate, thin pinnules. 

 Pinnjc opposite below, alternate above, approximate. Pinnules 

 large and wide, stalked, deeply serrated, each tooth ending in 

 a spine. Pinnules equal in size above and below, except the 

 superior basal ones, which are larger and divided to the costa. 

 Stipes and rachis covered with reddish hair-like scales. My 

 thanks are due to the llev. Charles Padley, of Bulwell Hall, 

 for fronds. 



BuACHiATUM-MULTiFiDUM, Lowe. — Found near Exmouth, in 

 Devonshire, by Mr. 11. J. Gray, of St. Thomas', Exeter. An 

 interesting variety. Like Brachiatum, this variety has its lowest 

 pair of pinna) very much the largest, and giving the appearance 

 of branches; in a frond thirteen inches in length, the basal 

 pinna) were four inches and a quarter in length, whilst the 

 next pair were only two inches and a half; their width is also 

 much greater, the basal ones being in the widest part an inch 

 across, whilst the next pair are only half an inch. With the 

 exception of the base the width of the frond is only four inches, 

 or only half that of the width across the basal pinna). The 

 pinna) arc various in size, scarcely two alike. Distinctly tri- 

 pinnatc, the two or three basal pinnules on the lowest pinna) 

 having at their base a pair of lobes, which are distinctly stalked, 

 and of which the lobe next to the rachis is only a fourth of 

 the size of the other, the larger lobe being in i'act the auricle, 

 and itself auricled. The pinnules more or less obtuse, (but not 

 so much so as in Brachiatum,) except near the apex; various 

 in size; nearly all stalked with the exception of the apices of
