590 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA, 
L. vernicosum, Hk. & Grev., founded on South-Indian examples, which has more obtuse, 
more dense, and more coriaceous leaves.—Spring also says that Griffith found in 
Gorval and Boutan (see Monogr. Lycopod. 2nd pt. 16, 17) L. ceylanicum, Spring, which 
differs by having the leaves not reflexed.—Mr. Baker has lately revised Lycopodium, and 
finds that this Sikkim plant is identical with the American species, and differs from the 
South Indian; and I owe this correction to him.—Pl. LXXXIV. fig. 1. 
2. L. HAMILTONII, Spreng. ; Hk. & Grev. in Hook. Bot. Misc. ii. 366. Stems erect, short, 
rigid; leaves 4—4 in., oblong, obtuse, entire, sessile, narrowed much at the base, 
subpatent, often tortuous when dry, entire, thick, coriaceous, margin manifest 
reflexed.—Spring, Monogr. Lycopod. 2nd pt. 16, not of Ist pt. 35. Z. obtusifolium, 
Ham. in Don, Prodr. Fl. Nep. 18; Wall. Cat. 134, not of Swartz. 
Kumaon, alt. 4000 feet; Strachey & Winterbottom. Nepaul and Sikkim alt. 5000- 
7500 feet; Wallich, C. B. Clarke. Khasia; alt. 4000-5000 feet, frequent.—Distrib. 
Burma, Bombay. | 
Mr. Baker unites with this Z. aloifolium, Wall. Cat. 129; Hk. & Grev. in Hook. Bot. 
Misc. ii. 367, Ic. Fil. t. 233; Spring, Monogr. Lycopod. 2nd pt. 15 ; Zenk. Pl. Ind. t. 12. 
L. empetrifolium, Dalz. in Hook. Journ. Bot. 1852, 113. This only differs by having 
the leaves sessile, hardly narrowed at the base. There is no difference in the nervation 
of the leaves. I do not know why Spring excludes Zenker's plate, which appears very 
good. : 
Var. petiolata. Leaves thinner in texture, narrower, longer petioled or subpetioled, 
less closely imbricate, margin less prominent, hardly recurved. | 
Khasia, alt. 4000 feet; frequent.— The extreme form of this, with its narrow, lax, 
loosely scattered leaves, appears distinct; but there are numerous intermediate states. 
9. L. seracEuM, Ham. in Don, Prodr. Fl. Nep. 18. Stems lax, often pendent or elongate; ` 
leaves 4-3 in., linear, acute, adpressed or patent, entire.—Spring, Monogr. Lycopod.. 
42. L. pulcherrimum, Wall. Cat. 115; Hk. & Grev. in Hook. Bot. Misc. ii. 367, 
Ic. Fil. t. 38... L. subulifolium, Wall. Cat. 114; Hk. & Grev. in Hook. Bot. Misc. 
ii. 367, Ic. Fil. t. 49. L. gramineum, Spring, Monogr. Lycopod. 2nd pt. 19. S 
From Kumaon to Bhotan, alt. 4000-8000 feet, common. Khasia, alt. 4000-6000 feet, i. 
common.—Distrib. South India, Columbia. | 
^ This species has two forms, viz. :— 
Var. subulifolia, Wall. Leaves narrowly linear, green, lax, with no distinct midrib, in d 
spreading plants patent, in pendent plants laxly adpressed. p. 
Var. pulcherrima, Wall. Branches rather stiffer, leaves rather broader, with midrib = 
distinct beneath, ascending, crispedly incurved when dry. a 
— LL. subulifolium, Spring, Monogr. Lycopod. pt. ii. 19, should be done away di E 
: altogether Wall. Cat. 114 is not Zenker's plant, nor has Zenker's plant been gathered — 
in Nepaul Probably Spring has been misled by the mixture in the duit of 
Wallich's plants.] Cte
