118 Underwood and Lloyd: Lycopodium 



Jamaica : Salt Hill (a mile off the Content road from Gordon- 

 town to Cinchona), growing in deep Sphagnum, 1903, Underwood 



157- 



The above collection represents, so far as known, the only one 



made in Jamaica since the time of Svvartz. The fine material col- 

 lected indicates a species abundantly distinct from that common in 

 the vicinity on dry banks. 



32. Lycopodium tortum Sieber, sp. nov. 



A robust much-branched terrestrial plant with long pendent 

 strobiles. Stems erect or ascending, a meter or more high, the 

 secondary branches spreading, triangular in outline, attaining 20 

 cm. broad by 1 5 cm. high, repeatedly branched, the terminals 

 inclined irregularly downwards and bearing the sessile strobiles ; 

 leaves on the older axes 5 mm. long by 0.5 mm. wide (on younger 

 axes as short as 3 mm.) curved upwards and outward, becoming 

 less curved and more widely spreading on the older axes, the curve 

 commencing at about the middle, and the leaf tapering from above 

 the middle to form an acute apex ; margins entire ; strobiles 1.5-2 

 cm. long, 3-4 mm. in diameter, cylindric or slightly angulate at 

 the apex ; sporophyls appressed, widely spreading, and but little 

 curved when dry, 2.5 mm. long by 1 mm. wide, the margins 

 irregular, with small scattered uneven teeth. 



Range : Higher (volcanic) summits of the Lesser Antilles ; 



specimens have been examined as follows : 



St. Kitts: Mt. Misery, Britton & Cowell 550. 



Guadeloupe: Mt. Perrin (herb. Torrey); 1898 (Jierb. Jenmaii). 



Dominica : In old crater near Boiling Lake, Laudat, Lloyd 315. 



Martinique: 1897 (Jierb. Jenman); Sieber, Fl. Mixta 328 



(Jierb. Kew). 



St. Vincent : H. H. & G. W. Smith 32. 



This species was long ago issued by Sieber under the above 

 name, which in deference to him we have here taken up for the 

 coarse plant of striking habit concerning whose distribution we 

 have now quite definite information. In St. Kitts the species is 

 locally known as "Stag Horn." This plant has been confused 

 with L. cnrvatum Sw., the type locality of which (Jamaica) is quite 

 outside the range of the peculiar species of the volcanic islands. 



A second species allied to the last was collected in 1902 by 

 Percy Wilson in the Luquillo Mountains, Porto Rico (no. ioi\ 

 but the specimens are unfortunately in the vegetative condition
