long, 4 — 5 mm. diam., rarely solitary, mostly 2 or more (even to 15) on 

 a long, branched, common peduncle provided with distant, erect or 

 somewhat spreading, lanceolate-subulate, minutely denticulate bracts; 

 sporophylla broadly ovate, imbricate, eroso-fimbriato, with the apex scariose- 

 acuminate or hair-pointed. — Very variable, with forms between which 

 it is difficult to draw the precise limit. 



Forma typica: Secondary branches rather crowded, erect or suberect; 

 leaves entire or those of the main stem obsoletely denticulate, those of 

 the ultimate branchlets erect or suberect, straight or somewhat incurved, 

 crowded. — Cosmopolitan in the temperate zones and in the cool alpine 

 regions of the tropics. 



l^ar. divaricatuiu : Like the type but the secondary branches 

 and the leaves more divaricating or spreading, more loose. — Java, 

 Philippines; Br. India.
