• "^f ^^^f ^y^ ^*^™® « ^'^^ ^ of tbe present plant I can find no difference, except 

 in the relative length of tbe stamens and style ; and, as tbcre are instances of an 

 exactly corresponding kind amongst i)i^ Ruhiacets 2iii^ Er^throx7/!e^, and I believe 

 also m tbe Oxahdacea, this difference is scarcely sufficient to found a specific cha- 

 racter upon. The seeds in both forms are delicately muricated, or frequently nearly 

 smooth. As regards the figure in Humph. Amb. lib. xi. t. 72. f. 3, quoted by

 page 173 of the same volume, there can be but little doubt of its behig intended for 

 tne plant now under consideration, although Grisebach refers it to a species closely 

 allied to, if It indeed be more than a state of L, cristainm.
