8. 1m. densum (dense), Labill. PL Nov. Holl. ii. 104 t. 251; Benth. Fl. 

 Austr. vii. 676, Stems from a short creeping base, erect, rigid, usually 1 to IJ 

 but sometimes 2 to 4ft. high, very densely branched in the upper part. Leaves 

 crowded all round, those of the main stem lanceolate with scarious tips and 

 often 2 lines long, those of the branches imbricate and scarcely 1 line long. 

 Spikes numerous, terminal, erect and sessile, from under Jin. to lin. long. 

 Bracts ovate-lanceolate, with spreading tips often scarious on the margins. — R.

Hab.: Inland southern localities. 



Also in New Zealand and Norfolk Iiland. 



3. SELAGINELLA, Spring. 



(Diminutive of Selago, the old name for Lycopodium.) 



Stems leafy, usually much branched, more slender or smaller than in 

 Lycopodium. Leaves small, entire or minutely serrate, inserted all round the 

 stem but in four rows. Spore-cases of two kinds, small ones filled with minute 

 powdery spores called microspores, and larger containing 1 to 6 larger spores 

 called macrospores, all opening in 2 to 4 valves and sessile in the axils of bracts 

 in terminal spikes. 



The genua has the same wide range as Lycopodium. The genorio character, the presence of 

 two kinds of spores, is probably constant, but requires a close observation to verify it. 



Small erect plants. Stems-leaves all similar. Spikes slender, the bracts 



imbricate in 4 rows. 



Stems from a branching base, simple, about lin. long 1. S. Preitsiana. 



Stems branching upwards, 2 to 6in. or sometimes more 2, 5. uUginosa. 



Stem-leaves in two outer rows distichous and spreading, 2 inner rows closely 



appressed. Spikes slender, the bracts imbricate in 4 rows. 

 Stems bare at the base, ascending or erect, very much branched upwards 



to a length and breadth of 6 to lOin. (in outline) 3. iS. flabellatum. 



Stems diffuse or creeping and much branched. 



Plant wiry. Spikes about 8 lines long 4. S. australiensis. 



Plant a delicate creeper. - Spikes 3 to 6 lines long 5. S. brisbanends. 



Plant shortly creeping. Stems dense. Spikes 1 to 3in. long .... 6. 5. Bakeriana. 



Plant usually smaller than the last. Spike oblong, the bracts spreading, 



nearly resembling the stem-leaves • 7. S. proniflora. 



Stems simple, lin. high. Spikes very short 8. S. pumilio. 



1. S. Freissiana (after L. Preiss), Spring, Monogr. Lycop. ii. 61 ; Benth. 

 Fl. Austr. vii. 677. An erect slender annual of 1 to 2in., divided at the base into 

 simple or once forked branches leafy throughout. Leaves all similar, spreading, 

 very narrow, acuminate, J to f line long. Spikes occupying usually the greater 

 part of the plant. Bracts the length of the stem-leaves, acute or acuminate, 

 imbricate in 4 rows. — F. v. M. Fragm. v. 112 ; Lycopodium gracillimum, Euuze 

 in PI. Preiss. ii. 109. 



Hab.: Stanthorpe. 



2. S. uliginosa (of swamps), Spring, Monogr. Lycop. ii. 60 ; Benth. FL 

 Austr. vii. 678. Stems from a creeping base erect or ascending, slender but 

 rigid, branching and . leafy throughout, usually 2 to 6in. long but occasionally 

 much drawn up. Leaves all similar or nearly so, ovate-lanceolate, acute, keeled, 

 spreading or at length reflexed, sometimes oblique but not vertical. Spikes 

 terminal, slender, from 3 or 4 lines to lin. long. Bracts smaller, narrower, and 

 more acute than the stem-leaves, imbricate in 4 rows, the points appressed or 

 slightly spreading.— Hook. f. Fl. Tasm. ii. 158; F. v. M. Pragm. v. 112;
