156 FLORA OF TASMANIA. | Lycopodiacee. 
Spring, of New Zealand, and another, with shorter, smaller, more subulate leaves, and axillary capsules, passes into 
L. Selago. In the ‘Flora Antarctica’ I have hazarded the opinion that this, and very many other species of the 
Selago group, are mere varieties of Z. Selago itself, strangely altered by locality and climate. In its ordinary state 
L. varium may be recognized by its stout, erect stem (6-18 inches high) and branches, patent or generally imbri- 
cated, decurrent, linear, coriaceous, blunt leaves, and stout, drooping, tetragonous spikes of capsules, with short, 
ovate, keeled, blunt, imbricating scales: these scales however often become foliaceous (in var. umbrosum, Br.), when 
the spicate character is lost. When the leaves become more subulate and smaller, the plant appears to pass into 
L. Selago. When it inhabits warmer latitudes it grows dependent from trees, is much branched, more slender and 
flaccid, and becomes Z. Billardieri. I cannot distinguish this species from the Z. gnidioides of South Africa and 
the Mauritius by any ee of importance.—PLATE CLXX. B-F. Forms of L. varium, showing the passage to 
L. Selago (Fig. A). 
: $ b. Leaves imbricated all round the stem. Spikes adal sessile. 
3. Lycopodium densum (Lab. Fl. Nov. Holl. ii. p. 104. t. 251. f. 1); caule erecto superne fasti- 
giatim ramosissimo, foliis sex-multifariam imbricatis erectis et appressis v. patulis et squarrosis subulato- 
lanceolatis integris longe acuminatis piliferisve, spicis terminalibus solitariis sessilibus ramulis latioribus 
oblongo-cylindraceis squarrosis, squamis scariosis triangulari-ovatis, sporis hispidis.— Br. Prodr. 165; 
Spring, Monog. p. 81; Fi. N. Zeal. i. 53. (Gunn, 49, 323, 1556.) 
Has. Abundant in heathy places, etc., throughout the Island.—(v. v.) 
DistriB. Victoria and New South Wales, New Zealand, Pacific Islands. 
A very handsome plant, which, though variable in foliage, cannot be confounded with any other.—S/ems pro- 
strate below, then tall, erect, rigid, woody, stiff, 1-3 feet high, copiously fastigiately branched; branches rarely 
spreading and lax, densely covered with sguarrose, spreading or closely imbricated, appressed, subulate, acuminate, 
rarely hair-pointed leaves: the character of the branches depends on the form and disposition of the leaves, which 
are sometimes short, erect, closely appressed, sexfariously imbricated, when the branches are slender; when the 
leaves are spreading and incurved, the branches appear stouter. Spikes cylindrical, 3-3 inch long, sessile, blunt, 
sguarrose from the spreading, scarious, yellow scales, which are peltate, triangular, serrulate or erose. The spores 
are hispid with short blunt projections. 
4. Lycopodium laterale (Br. Prodr. 165); caulibus repentibus, ramis ascendentibus erectisve et 
elongatis foliosis simpiicibus v. divisis, foliis undique imbricatis sguarroso-patentibus incurvis anguste subu- 
latis integris, spicis brevibus lateralibus cylindraceis, squamis subquadrifariam imbricatis late triangulari- 
ovatis coriaceis.—Lab. Sert. Aust. Caled. p. 10. t. 15; Spring, Monog. p. 82; Fl. N. Zeal. ii. 53. (Gunn, 
57.) 
Var. Ø. diffusum; caulibus diffusis prostratis, ramis ascendentibus.—L. diffusum, Br. Prodr. 1. c. 
(Gunn, 1558.) 
Has. Var. a. Rocky Cape, Guan. Var. 8. Alpine bogs, common.— (v. v.) 
Disrris. Victoria, New South Wales, New Zealand, Pacific Islands. 
A variable plaut in habit.—Stems procumbent, sparingly branched below; ¿ranches slender, erect, simple or 
sparingly divided, 3 inches to a span tall, covered with patent, flexuous, squarrose, narrow subulate leaves, which 
are $ inch long. Spikes axillary, sessile, erect, } inch long. Scales quadrifarious, coriaceous, very broadly ovate or 
rounded, suddenly contracted to a rather long stiff point; margin scarious, white, very narrow.—In alpine places 
this plant becomes procumbent, shorter, stiffer, and with broader, shorter leaves; such specimens appear to me to 
be L. diffüsum, Br. 
$ c. Leaves imbricated all round the stem (sometimes obscurely secund or bifarious). Spikes peduncled. 
5. Lycopodium Carolinianum (Linn. Sp. Pl. 1567) ; caule repente radicante, foliis ascendentibus
