GOMPLANATUM GROUP 



The only member of this group in the West Indies we de- 

 scribed from herbarium material before having seen the plant in 

 the field. Like L. clavatum of another group, L. Fawcettii forms 

 a weed in the paths of the Cinchona plantation and grows luxuri- 

 antly, ascending over bushes and low shrubbery in a sprawling 

 fashion and is thus quite in contrast with its more modest congeners 

 of the Northern States, The status of L. thyoides H.B.K. of 

 South America still remains to be determined. Our single West 

 Indian species is

SCARIOSUM GROUP 



The members of this group are mostly from tropical or south 



temperate regions. Lycopodium scariosum, with which Baker has 



confused the American species, is from New Zealand, and there 



are other Old World species. The American species are mostly 



South American, only a single species reaching Jamaica in the 



West Indies. The American species may be separated as 

 follows : 



Lateral leaves of the dorsiventral branches directed upwards, straight, rigid, tapering 



from the base, not sharply pointed nor crowded. 39. Z. Gayanum. 

 Lateral leaves of the dorsiventral branches curved downwards. 



Leaves ascending, cuspidate, strongly revolute. 42. Z. Holtoni. 

 Leaves spreading, slightly curved. 



Lateral leaves broad near the apex, obtuse. 40. Z. lindsaeacentn. 



Lateral leaves broadest at the decurrent base. 41. Z. Jusstaeu
