\Botrychium. 
2. Botrychium Sw. Moon-wort. (Tab. XI. f. 3.) 
Capsules subglobose, sessile, clustered at the margin and on 
one side of a pinnate rachis, 1 -celled, 2-valved, compressed, 
opening transversely. Involucre 0. — Veins forked- — Name : 
fiorpvQ, a hunch of grapes ; from the appearance of the branched 
clusters of capsules. 
]. B. Lunaria Sw. (common M.) ; barren branch of the frond 
usually solitary linear pinnate, pinnae usually lunate or subfla- 
belliform crenate or toothed with radiating veins. Newm. p. 
337 ; ed. 3, p. 313. Osmunda L. : E. B. t. 318. 
Dry mountain pastures and downs or links by the sea. 2/.. 6 — 8. 
— Specimens of this are occasionally found with more than one barren 
branch to the frond. 
[2. B. rutdceum Sw. (rue-leaved M-) ; barren branch of the 
frond solitary deltoid subpinnate, pinnae few (3 — 4 pairs), linear 
or cuneate incise or pinnatifid with a midvein. Newm. ed. 3. 
p. 322, 324. B. Lunaria d. Sm. : Newm. p. 348. 
Mountain pastures and links near the sea. Westmoreland (Ray). 
Sands of Barrie : Mr. Cruickshank. If.. 8. — We have not ourselves 
seen British specimens; B. simplex Hitchc. (Hook, et Grev. Ic. Fil. 
t. 82) appears to be the same species. It is probable that Smith was 
correct in referring it to B. Lunaria, none of the varieties he mentions 
being “ so numerously distinct as to have the appearance of a different 
species ” : an observation that applies well to this one, only three speci- 
mens having been found on the Sands of Barrie, and none elsewhere 
since the days of Ray.] 
Ord. CXI. LYCOPODIACEiE Sw. (Tab. XII. f. 1, 2.) 
Capsules sessile in the axils of leaves or bracteas, or lodged 
within a cavity in their base, without a ring, 2 — 3-valved 
or indehiscent. Involucre 0 (unless a cavity in the base of the 
leaves). Sporules or seeds sometimes of two kinds, which are 
then contained in different capsules. Leaves and bracteas cau- 
line, rarely all radical and then arising from a cormus (solid 
bulb). Vernation straight (not circinate). 
1. Lycopodium. Stems leafy. Capsules 1-celled, 2-3-valved, free from 
the leaves or bracteas. Terrestrial plants. 
2. Isoetes. Leaves all radical. Capsules indehiscent, seated in a 
cavity at the base of the leaves. Aquatics. 
1. Lycopodium Linn. Club-moss. (Tab. XII. f. 1.) 
Stems leafy. Capsules 1-celled, 2-valved, containing nume-
