They are of spreading habit, witli bright green stalks of some length, and spring from a stout, erect caudex, but less compact than that of L. fdix-mas and others, which send up their fronds in erect circlets. The round spore heaps are fairly large, and very plentiful and dark in colour, the kidney- shaped indusium obvious, but only partly covering them when ripe. Our plate gives a good idea of the form. It has " sported " fairly freely, and is a very variable fern in minor details, but a great many of the forms recorded are too erratic or indefinite to recommend for culture, and for that reason are probably not now in existence. These we Fig 148. L. dilalala (parts of pinna). Crist ATA (Fig. 149).— Found near Doncaster by Mr. Appleby; prettily crested at frond and pinnae tips ; a better form was found in Devonshire by Mr. C. Jackson, and another by Mrs. Thompson, also in Devon. C. Druery.—Found by the writer at Clovelly; a very robust form with bunch crests of medium size. C. OscROFT.—Found near Bristol; a very finely bunch - tasselled form, somewhat crispy in make. C. GRACiLE Roberts.—A very pretty percristate form, the pinnules being fanned. Unfortunately, though pro- duced so freely from spores as to appear abundantly as strays under glass, all without exception have a tendency to partial depauperation, short pinnae oc- curring here and there. Folios A - CRIST ATA, f. digit ata.— Although found in the Azores by Mr. Brown, and therefore best grown under Fig. 149. L. dn. aistata (pinna)..
