Underwood and Lloyd: Lycopodium 115 



Range: Cuba {Wright pjd, Eggers 5165), Porto Rico {Sin- 

 tenis 1546, Percy Wilson 155), [Hispaniola, Guadeloupe], Bolivia 

 {Rusby 458). The last named plant is sterile but cannot be 

 separated by its foliage ; it is distinct from Mandon ij2Q y which 

 is L. siibulatiim. 



27. Lycopodium dichaeoides Maxon, Proc. Biol. Soc. Washing- 

 ton 18 : 231. 1905. (Type from Guatemala, Cook & Griggs 



Guatemala : Alta Verapaz, near Sepacuite, Cook & Griggs 

 231 ; between Sepacuite and Secanquim, Maxon & Hay 3268. 

 Known only from these two collections now in the United States 

 National Herbarium.

18 1 3. (Type from <( Amer. mend/') 



Represented in typical form in the herbarium of the New York 

 Botanical Garden only by sheets of Mandon 1529 from Bolivia. 

 There are numerous variations, some of which have been described 

 by Baker. Among these are two sheets from Ecuador collected 

 by Sodiro, which are marked " var. pastoense" which differ from 

 each other and must be compared with Baker's type before they 

 can be definitely placed. They probably represent one or more 

 distinct species. 



29. Lycopodium roraimense sp. nov. 



A long slender pendulous epiphyte with sporophyls much 

 longer than the sporangia. Stems over 75 cm. long, 2-3 forked, 

 dorsiventral (except in the sporophyllary region) by the twisting 

 of the leaves, the strobile elongate (30 cm.) and radially symmet- 

 rical ; leaves lanceolate-ovate, acute, 8-9 mm. long by 2.5 mm. 

 wide, twisted at the base, entire, thin, the midrib slender but dis- 

 tinct ; sporophyls triangular, small, 1.5-35 mm. long by 1-1.5 

 mm. wide, extending beyond the sporangia in a point, the margins 

 entire ; sporangia conspicuous, nearly circular, exceeding the 

 sporophyls in width. 



British Guiana : Forest slopes near Roraima {herb. Jenmati). 

 This plant differs from L. subulatum, its nearest ally, in its wider 

 leaves and much longer sporophyls.
