This species, which by the older Botanists was confounded 

 with D. scoparium, as well as with the foreign D. Schraderi^ 

 bears the more striking resemblance to the latter, whose char- 

 acter is, however, to have more obtuse and carinate leaves, 

 with their nerve disappearing before the points. With D. 

 scoparium our plant agrees in having very remarkable perichse- 

 tia, one of which encloses two, three, and even four fruitstalks ; 

 in some foreign species allied to this we have seen as many as 

 seven. The transverse undulations of the leaves may be per- 

 ceived on the plant while growing, although this appearance 

 becomes more evident in dried specimens.
