29. Lycopodium Fawcettii sp. nov. 



Horizontal stems trailing giving off at intervals of 2-3 cm. lax 

 clusters of much branched aerial stems (12-15 cm. high) of two 

 sorts, vegetative and peduncular ; the vegetative branches flattened, 

 the ultimate divisions elongate slender and rigid (1.5 mm. wide) 

 with four rows of appressed leaves, those of the under row reduced 

 to a triangular tip ; peduncular stems arising from near the ground, 

 branching about six times, thick, terete, the ultimate branches the 

 thinnest with 6-8 rows of triangular, thin, membranous tipped 

 leaves ; many of the peduncular stems produce ultimately ses- 

 sile strobiles 2-3 cm. long which scarcely exceed the negative 

 branches, sporophylls broader than long, very abruptly contracted 

 into a subulate tip, sporangia reniform. 



Jamaica : ex herb. Botanical Garden, 1885 (N) (U. S. Nat. Herb 

 22368=type) ; Wilson, 1863 (C), a form with abnormal peduncu- 

 lar stems.
