2. LYCOPODIUM, Linn. 



(From lykos, a wolf, and pom, a foot, supposed resemblance of the roots). 

 Stems leafy, hard, branching, creeping prostrate or erect. Leaves small, 

 entire or minutely serrate, inserted all round the stem, usually in 4 rows. 

 Spore-cases all of one kind, flattened, 1-celled, 2-valved, sessile in the axils of the 

 upper leaves, or of bracts usually smaller or broader than the stem-leaves and 

 forming terminal or lateral spikes. Spores all minute and powdery. 



The genus is widely spread over every part of the globe. 



Leaves lanceolate, cai-tilaginous, crowded all round the stem, mostly 



3 to 6 lines long. 

 -Stems elongated, ascending. Spikes terminal, usually several. Bracts 



smaller than the stems-leaves but much longer than the spore-cases 1. L. varium. 

 Stems elongated, pendulous. Spikes terminal, several. Bracts 



scarcely exceeding the spore-eases 2. L. phlegmaria. 



Only differing from the preceding in that the leaves are in wing-like 



■^ows 3. L. phlegmarioides. 



The whole plant glaucous ... 4. £,. Clarce: . 



Leaves usually narrow, crowded round the stem, under 3 lines long. 



Spore-eases in spikes, with small broad bracts. 

 Spikes pedunculate. 

 Stems creeping, short or scarcely branched. Spikes single on lateral 



erect peduncles bearing small leaves . . 5. L. Drummondii. 



Spikes sessile, lateral. 

 Stems branched at the base, elongated and slender. Leaves subulate 6. L. laterale. 



Spikes sessile, terminal, usually short. Stems, often above 2ft. long. 

 Branches numerous, sprieading or flexuose. Spikes nodding .... 7. L cernuum. 



Stems and branches erect, dense. Spikes erect 8. L. densum. 



1. Ii. varium, (variable), R. Br. Prod. 165 ; Benth. Fl. Austr. vii. 

 674. A variable species, the smaller plants often compact, usually decum- 

 bent or elongated and rooting at the base, with ascending branches of 6in. to 1ft. 

 Leaves crowded all round the stem, lanceolate, obtuse, spreading or rarely erect, 

 3 or 4 lines or sometimes nearly ^in. long. Spikes terminal; 1 to 4in. long, solitary 

 or 2 or 3 together, continuous with the leafy branch with bracts sometimes leafy 

 2 or 3 lines long, in other specimens short broad obtuse, imbricate in 4 rows, and 

 1 to 2 lines long, almost as in L. phlegmaria, or small and acuminate. Spring.

Also in New Zealand, the Pacific Islands and South Africa. 



2. Im. phlegmaria, (from its" supposed medicinal properties in cases of 

 inflamation), Linn. ; Spring. Monogr. Lycop. i. 63, ii. 28 ; Benth. Fl. Austr. 

 vii. 674. Tasseled Club-moss. Epiphyte, the plants often large. Stems 

 elongated, usually pendulous from rocks or trunks of trees. Leaves scattered, 

 crowded, cartilaginous, spreading, mostly lanceolate and 3 to 6 lines long, but 

 occasionally oblong and obtuse. Spikes slender at the ends of the branches.
