Underwood and Lloyd: Lycopodium 121 



Sporophyls serrulate; under leaves triangular, nearly as broad at base as long; sporangia 

 round-renate. 



36. L. goyazense. 



Sporophyls entire. 



Sporangia depressed-renate ; under leaves ovate, acute. 37. Z. meridionale. 



Sporangia round-renate ; under leaves lanceolate. L. carolinianutn. 



36. Lycopodium goyazense sp. no v. 



A small creeping plant with stout erect branches bearing large 

 strobiles. Creeping stems 6 cm. or more long, notably dorsiven- 

 tral, producing occasional short branches ; leaves strongly dimor- 

 phic, those of the two under rows appearing lateral, triangular, 

 symmetric, 2 mm. wide at the base, not contracted, 2.5 mm. long, 

 acute, entire, thick, somewhat imbricated ; those of the three upper 

 rows small, triangular, twice as long as broad or more, stiff, remote 

 from each other and thus exposing the broad upper surface of the 

 stem ; erect branches (peduncles) 7-9 cm. long, 1.5 mm. thick, 

 with triangular scale-like leaves which are 4 mm. long by 1.5 mm. 

 wide at base and serrulate ; strobiles 3-4 cm. long, stout ; sporo- 

 phyls larger than the lateral leaves, 2.5 mm. wide by 5 mm. long, 

 ovate, acuminate, not contracted above the middle ; margins serru- 

 late throughout. 



Brazil : Goyaz, Glaziou 22644. ; also less perfect specimens 



from Minas Geraes, Claussen. 



37. Lycopodium meridionale sp. no v. 



A small close-creeping, sparingly branched plant with solitary 

 upright strobilary branches. Creeping stems up to 40 cm. or more 

 long, 1-1.5 mm. thick, with occasional short (2-4 cm.) lateral 

 branches ; leaves strongly dimorphic, those of the two under rows 

 appearing lateral, 5 mm. long by 2 mm. wide, ovate, acuminate, 

 falcate, the midrib curved asymmetrically and parallel to the proxi- 

 mal leaf-margin ; leaves of the upper four rows subulate, spread- 

 ing, 3.5 mm. long by 1 mm. wide; upright branches (peduncles) 

 8-26 cm. long, oftener rising from the short prostrate branches, 

 with whorls of subulate spreading scale- like leaves with parallel 

 margins or slightly contracted below the middle, entire or slightly 

 erose near the base ; strobiles 2.5-8 cm. long ; sporophyls 2 mm. 

 wide by 4 mm. long, triangular, contracted at the middle and 

 subulate above, spreading, the margins entire above, erose below 

 the middle, those of the same level not contiguous. 



Range: Probably widely distributed through the tropics of 

 meridional America. Specimens have been examined as follows :
