‘The Seemann specimens have received considerable 
attention; determined originally by Seemann as JD. cal- 
amiforme Lodd., a synonym of D.teretifolium KR. Br., 
they were placed in D.crispatum (Forst.) Sw. by H.G. 
Reichenbach in Seemann’s Flora Vitiensis. Rolfe de- 
scribed the plant as new in 1921 under the name D.cal- 
amiforme, a name which may not be used, according to 
the present rules, because of the previous D.calamiforme 
Lodd.
