GUNNERA MAGELLANICA L. 



The length of the inflorescence and the petals vary much ; sometimes 

 the inflorescence is sessile, at other times on a 2 cm. peduncle ; flowers all 

 female at Gulf of St. John; in Dawson I. the peduncles were 10 cm. and 

 flowers mostly males. (E. D. W.) At Punta Arenas it covers the soil 

 and prevents the growth of grass. (Skottsb.)
