that is " Kurztriebe " of German authors. From the first basal cell 

 of the " Kurztriebe " are formed cortical cells which become 

 gradually smaller outward. Of five " Kurztriebe," those on the sides 

 standing- in a distichous way grow up here and there into branches, 

 the others remaining as hairs. In the cross section of a branch 

 there is a large central cell, from which five basal cells of " Kurz- 

 iriebe " are cut off verticillately and the interspaces are filled up with 

 cortical cells which are derived from the I asal cells of " Kurztriebe." 

 bruits of both kinds unknown. Colour vinoso-red, almost black in 

 drying. Substance soft and fleshy in fresh state.

Of the present genus only two species D, Preisii Sond. and D. 

 crvptocarpa (Holm.) Schm. have been found in New Holland. The 

 present plant which has the structure a little different from and sim- 

 pler than the typical species, is a distinct new species which has been 

 collected by Mr. M. Tago; hence the specific name.
