ticulations than the last : quite distinct in its mode of growth, for all the 

 pinnce are strongly curved backwards, in a direction contrary to that of 

 the fructification : the involucre is totally different, larger, browner, of a 

 more rigid texture, truly ovate, each valve remarkably convex for its 

 whole length, the edges only of the valves being applied to each other, 

 and they are quite entire. 



14. OsMUNDA. Linn. Osmund-royal, or flowering-Fern. 



1. O. regdtis, L. (^common Osmund-royal) ; fronds bipinnate, 

 pinnules oblong nearly entire the lower base somewhat auricled, 

 the inferior ones opposite, fertile panicle bipinnate occupying 

 the extremity of the frond. E. Bot. t. 209. 



Boggy place?, wet margins of woods ; very frequent in the N. W. of 

 Scotland, and S. of Ireland. — The noblest and most striking of our Ferns._ 

 Mr Stewart Murray has measured a tuft of its fronds on the banks of 

 the Clyde, which from the base, where they sprung from the ground, 

 were 1 1 h feet high. 



15. BoTRYCHiuM. Sio. Moonwort. 

 1. B. Lundria, S\v. (common 3Ioomcort); frond pinnated soli- 

 tary, pinnae lunate or subflabelliform crenate. — Osmunda, L. — 

 E. Bot. «. 318. 



Dry mountain pastures. — Varieties of this are found, with more than 

 one frond upon a stalk and with the pinnules laciniated and even pinna- 

 tifid. Captain Carmichael communicated specimens to me, which bore 

 capsules on the margins of their lower pinnules. 



16. Ophioglossum. Linn. Adder's-tongue. 

 1. O. vulgdtum, L. {common Adders t07igue) ; spike cauline, 

 frond ovate obtuse. E. Bot. t. 108. 

 Moist pastures and in woods. 



CRYPTOGAMIA— LYCOPODIACE.E. 



1. Lycopodium. Litm. Club-moss. 



1. L. clavdtum, L. {common Club-moss'); spikes in pairs cylin- 

 drical stalked, their scales ovate acuminate eroso-dentate, stem 

 creeping, branches ascending, leaves scattered incurved and hair- 

 pointed. E. Bot. t. 224. 



Heathy pastures, especially in mountainous countries. — The seeds being 

 inflammable are used to produce artificial lightning on the stage ; and 

 the Poles make a decoction of the plant to^cure persons afflicted with that 

 terrible disease, the plica polonica. Stems many feet long. 



2. L. an7i6li7ium, L. {interrupted Club-moss); spikes oblongo- 

 cylindrical solitary sessile terminal, stem creeping, branches 

 ascending dichotomous, branchlets simple, leaves in about 5 rows 

 linear-lanceolate mucronate serrulate patent. E. Bot. t. 17-27. 



Stony mountains of N. Wales, and in the Highlands of Scotland ; but 

 by no means general. Not unfrequent on the Cairngorum range. 



3. L. inunddtum, L. {Marsh Club-moss); spikes terminal sessile 

 leafy solitary, stem (short) creeping, branches simple few, leaves 

 linear scattered acute curved upwards. E. Bot. t. 239.
