 Lepido%ia Pearsoni is well distinguished fi'om L. reptans by the 

 following characters : — "In L. Pearsoni the whole plant is 

 very slender and elongate, and of a taAvny colour. Stems dis- 

 tantly pinnate, without any rooting flagella from the underside. 

 Leaves small, those of the stems usually distant, or at most 

 contiguous, cloven to beyond the middle into 4, sometimes 

 (though rarely) into 5 or 6, subulate subacuminate segments. 

 Stipulus cloven to the middle into 4, or not unfrequently 

 into 5, more rarely into 6, subulate obtuse segments. In- 

 florescence dioicous. Male spike terminal (rarely basal) on. 

 the lateral branches ; very rarely indeed on a short postical 

 ramulus." 



L. reptans is of a more robust habit, with shorter, more 

 closely branched stems ; of a deep green colour when fresh, 

 often turning bluish-white, or glaucous, in di'ying. Leaves 

 subimbricated, cloven only half-way into never more than 4 

 segments, which are 4-7 cells wide at the base ; cells broad 

 and long. Stipules with acute segTnents, which are never 

 more than 4 in number, even on the main stem, and are 

 sometimes reduced to 3. The chief distinction, however, is 

 in the monoicous inflorescence, with the male flowers uni- 

 formly in short catkins springing fi'om the underside of the 

 stem, which is their normal position in nearly every other 

 Eulepidozia known to us except L. Pearsoni. Dr. K. Spruce.
