Sphdyiiiim mJnnnl] icul'iun Warnst. 



Fairly robust, stems often reaching 18 cm., coma usually 

 golden yellow, divergent brancnes generally two, short, 

 divaricate to patent, 1-1.5 cm., pendants rather closely 

 appressed. Stem cortex of one row cf small cells, wood 

 cylinder thick ; stem leaves broadly ligulate, very obtuse. 

 2 mm., border well-defined 4-5 series, upper tracheids copi- 

 ously fibred, pores ringed, very numerous along both mar- 

 gins, usually one in each space between fibres, ring continu- 

 ous with cell-wall. Branch leaves ovate, rather obtuse, 2 

 mm., border well-defined, narrow, 2-3 celled, apex truncate 

 G-7 cusped ; tracheids 16-20^4 diameter, pores small, ringed- 

 very numerous along both margins included in cell-wall ; 

 cells in section small, elliptic approaching the ventral sur- 

 face but not free.
