Lycopodium lucidnlnin Michx. Fl. Bor. Am. 2: 284. 1803. 



Stems rising 6'-io' from a curved or decumbent base, 

 1-3 times dichotomous, the branches forming a loose clus- 

 ter of a few leafy vertical stems; leaves dark green, shin- 

 ing, wide-spreading or finally deflexed, acute, somewhat 

 oblanceolate, broadest above the middle, there more or less 

 erose-denticulate, tapering gradually to a narrower base, 

 arranged in alternating zones of longer and shorter leaves, 

 the latter more often bearing the sporanges, less denticu- 

 late, even entire ; plant often gemmiparous, the gemmae 

 ('"I s-\ early falling and giving rise to young plants.

In cold, damp woods, Newfoundland to British Columbia, 

 south to South Carolina, Tenness.ee and Iowa. Ascends to 

 nearly 5700 ft. in Virginia. Trailing evergreen, Moonfruit- 

 pine. Aug.-Oct.

 Underw. Lloyd's Club-moss.

Lycopodium porophilum Lloyd & Underw. 

 Bull. Torrey Club 27: 150. 1900. 



Stems rising 2' -4' from a curved or 

 decumbent base, 1-3 times dichotomous, 

 the branches forming a rather close tuft 

 of densely leafy vertical stems ; leaves 

 spreading or somewhat deflexed, entire or 

 minutely denticulate, arranged in alternat- 

 ing series of longer and shorter, the former 

 linear to linear-lanceolate, slightly broader 

 above the middle, alternate, the latter dis- 

 tinctly broadest at the base, gradually 

 tapering to an acuminate apex, and more 

 often bearing the sporanges; plant often 

 gemmiparous. 



On partially shaded rocks, apparently pre- 

 ferring sandstone, Wisconsin to Indiana and 

 Alabama : probably of wider distribution. 



4. Lycopodium inundatum L. Bog or Marsh 

 Club-moss. Fig. 103. 



Lycopodium inundatum L. Sp. PI. 1102. 1753. 



Plants small, with simple or i-2-forked horizontal pros- 

 trate or slightly arched slender, often lax, leafy stems; 

 peduncles 3"-2-J' long, arising directly from the creeping 

 stem, terminated by a slender spike i'-iS' long, or the spike 

 rarely subsessile; leaves of the stem linear-lanceolate, 

 acute, mostly entire, curved upward, those of the peduncle 

 more slender, spreading; sporophyls similar to the sterile 

 leaves but wider at the base (linear-deltoid), spreading, 

 entire or sometimes toothed just above the base. 



In sandy bogs, Newfoundland to Alaska, south and west to 

 New Jersey, Pennsylvania, Illinois, Michigan, Idaho and Wash- 

 ington. Also in Europe and Asia. Slender elongate forms, 

 mainly from^ New England, are known as the var. Bigelovii 

 Tuck. ; they indicate a possible transition into the next species.
