APPENDIX C. 
Linneus. — [MS. addition below ibe preceding]. Forte raera varietas prioris 
[palustre] ex solo aquse profundioris. 
Smith. — limosum ? Certe. 
E. N. — Four specimens, all with catkins, and identical with Eq. limosum of 
Smith. As there is no representative of Eq. limosum of Linneus, and as the 
marked copy of the work indicates that he did not possess it, I subjoin the cha- 
racter. 
Linneus. — [Sp. Plant.] Limosum, 5. Equisetum caule subnudo leevi, [here 
follow the synonymes]. Habitat in paludibus^ turfosis, profundis. 2/. 
. [MS. addition on the opposite page]. Hallerus hanc facit varie- 
tatem E. palustris. 
E. N. — It is clear that Linneus trusts to Ray as the authority for this as a 
distinct species, since he quotes his figure,* which evidently represents the un- 
branched form of Eq. limosum of Smith. Hence it seems that Eq. fluviatile of 
Linneus is the branched, and Eq. limosum the unbranched form of Eq. limo- 
sum of Smith ; and that Eq. fluviatile of Smith has no representative either in 
the herbarium or the works of Linneus. With respect to the observation of 
Linneus quoted above, that Haller makes this species a variety of Equisetum 
palustre, I think the criticism is an unjust one. Haller quotes Ray’s figure 3, 
and, as it seems to me, correctly, as a variety of Equisetum palustre ; while Lin- 
neus quotes Ray’s figure 2, which is evidently the Eq. limosum of Smith. A 
positive proof that the fluviatile of Linneus was not the fluviatile of Smith, ex- 
ists in the fact that he attempted to account for its increased size and altered 
appearance by its growing from the bottom of deep water ; this is the case with 
Smith’s limosum, but never with his fluviatile, which, on the contrary, affects 
loose gravelly and sandy places unconnected with water.

Linneus. — (Edific. ; hyemale. 
. [Sp. Plant. MS. addition on the opposite page]. Equisetum caule 
simplici aspero vaginis non laciniatis. Hall, Helv. 143. — Caulis viridis scaber, 
radiis [?] vaginae pallidae basi marginisque denticulis obsoletis atris gibbis. 
E. N. — A single specimen of Eq. hyemale of Smith. The word or abbre- 
viation “ CEdific.” implying its uses, is written apart from the name.

Linneus. — Tourelle. ^ 
Smith. — Asperrimum, Dick., variegatum, Jacq. H. B. — J. E. S. 
Anonymous. — Equisetum basiliense. No. 1678, halier. An species distincta 
apud cl. linn.? In horto cultum. 
E. N. — A single specimen of Eq. variegatum of Smith. Linneus answers 
the question as to its being a distinct species, by giving basiliense as a syno- 
Syn. t. 5, fig. 2, a, h.
