The present plant comes very near S. satsumana Maxim. ; but 

 differs from it in having 5-parted leaves, less spined fruits, smaller 

 flowers, and in the presence of cauline leaves ; and still more in the 

 structure of the fruits. As seen in the section of the fruit (PL XII.), 

 this plant differs greatly from the congener in the position of vittse. 

 The vittae in my species are very few, while in the other they are 

 as many as eight. An allied genus, Petagnia Guss., has no vitta in 

 its fruits, in which respect the present plant is the nearest to it. 



The five species of the distinct Umbelliferae. In the absence 

 of the mature fruits, the genera can not be determined with 

 ■certainty. 



Araliaceae.
