specimen, so he reinstated Lejeimea ulicina, Tayl., and made Lej. 

 Taylori a synonym of Lej. minutissima, Sm. Considerable con- 

 fusion as to these two species has consequently arisen, but if we 

 remember that the monoicous form with geniculate stems, no 

 stipules and often found fertile is the Lej. minutissima of Smith, 

 and the dioicous one with somewhat straight stems, stipules present, 

 and flowers extremely rare is Lej. ulicina, Tayl., we shall be right. 



Shortly before Dr. Spruce died he wrote me : " Lately I came 

 on the specimen given to Mr. Borrer by Sowerby as part of the 

 Jung, minutissima figured in Eng. Bot. You will see it is L. 

 ulicina, and when even Hooker did not discriminate between the 

 two it was impossible Sowerby should." In my plate of Lej. 

 ulicina, fig. 4, is a drawing of this plant ; in Hooker's " Brit. 

 Jung. " the two plants are given as Jung, minutissima, Sm., but as 

 I have never heard of any one collecting Lej. minutissima, Sm., in 

 the Lake District, I should infer that the station given by Hooker, 

 Keswick, refers to Lej. ulicina. Lej. ulicina, Tayl., is quite distinct 

 from any of the otlier British Lejeuneae.
