PHLEGMARIA GROUP 



This group with strongly dorsiventral leaves is largely repre- 

 sented in South America, but one of the species extends into the 

 West Indies. They may be separated as follows : 



Leaves broadly oval or obovate. 



Leaves small, 3.5 by 2.5 mm. ; sporophyls scarcely 



exceeding the sporangia. 

 Leaves narrowed (cuneate) at the base. 24. Z. cuneifolium. 



Leaves rounded at the base. 25. L. callitricaefoliitm 



Leaves larger, 6-8 by 3-5 mm. ; sporophyls extending 



into a point beyond the sporangia. 

 Sporophyls long, often attaining 20-40 cm. ; leaves 

 mostly regular. 



Sporophyls short, 1-2 cm.; leaves obtuse or nearly 



so, irregularly spreading. 27. L. dic/i^aeoides. 



Leaves lanceolate or lanceolate-ovate. 



Leaves 2 mm. or more wide ; sporophyls extending be- 

 yond the sporangia into a long point. 29. L. roraimense. 



26. L. aqualupianum 



Leaves under 2 mm. wide ; sporophyls shorter than the 

 sporangia. 



28. L. sub u latum 



24. Lycopodium cuneifolium Hieron. Bot. Jahrb. 34: 572. 

 1905. (Type from Costa Rica, Hoffmann 50.) 



Costa Rica : Vulcan deBarba, Hoffmann 50 ; with no locality, 

 1900, C. Werckle. A plant nearly allied to L. callitricaefolium but 

 readily separated by its more distant narrowly obovate leaves. 



25. Lycopodium callitricaefolium Mett. Ann. Sci. Nat. V. 3: 



309. 1865. (Type from Bogota, Colombia, Triana.) 

 Range : Ecuador {Spruce 4792, Sodiro), Colombia, Costa Rica 

 ( I Varsc eu icz 12.) 



26. Lycopodium aqualupianum * Spring, Monog. Lycop, 1 : 68. 

 1842. (Type from Guadeloupe, L Herminier, and Hispaniola, 

 Neckour. ) 



*This name is probably a misprint for guadalupiannni to which form Fee changed 

 it in 1866; Urban (I903) writes it " guadeloupeanum ." We retain the original 

 orthography as safer.
