Fig. 218. P. ang. acutilobum. 
Асотповом (Fig. 218).—Found near Barnstaple by Mr. С. 
Jackson; this represents a section, embracing a number of very 
fine forms, found by В. J. Gray, Mrs. Hartley, W. H. Phillips, 
G. B. Wollaston, Dr. Allchin, Mr. Choule, Mr. Dadds, F. Foot, and 
Mr. Wells; the pinnules are long and slender, and very acutely 
pointed, and the varieties are generally proliferous. The term 
“ acutilobum ” has been substituted for “ proliferum,” so many other 
forms bearing bulbils. (See Appendix No. LXXVI). 
ACUTO-GRACILE (Plate XXIX).—Found near Ottery St. Mary by 
Mr. G. B. Wollaston ; a dwarf form with acutely pointed pinnules. 
ALATUM (Plate XXIX).—A remarkable form, the normal wedge- 
shaped bases of the pinnules being much widened at point of attach- 
ment so as to form a continuous wing connecting them. 
BRACHIATUM.— Found in Devon by Mr. Hillman; this form is 
very wide at the base, the lower pinne expanding almost into 
fronds; several types of this have been found by others forming 
a very distinct section. (See Appendix No. LV and ГУП). 
BRACHIATO-CRISTATUM KEALL.—Fronds branch into three from 
the bottom, forming a trident, such terminal bearing a bunch crest. 
CAPITOSUM.—Found by Mr. Moly at Tatworth ; narrow-fronded 
grandiceps. 
ConcHATUM.—Found by Mr. Moly at Hawkhouse; shell-like 
pinnules.
