status. It must be a species of Columella or of Tetrastigma, if it 

 belongs in the Vitaceae, as it probably does. I have not been able 

 to refer to it any of our Amboina specimens, but further explora- 

 tion of Amboina may yield material that will lead to a more 

 definite determination of its status.

The specimen agrees perfectly with Rumphius's description 

 and illustration and is manifestly the species commonly known as 

 Cissus geniculata Blume, here called Columella geniculata Merr. 

 Lamark, Encycl. 1 (1783) 31, reduced it to Cissus carnosa Lam.= 

 C. trifolia K. Sch. of which, however, it is not the type. In this 

 erroneous reduction he was followed by all authors who have had 

 occassion to cite the Rumphian illustration ; namely, Vahl, Willde- 

 now, Retzius, Poiret, Roemer and Schultes, Pritzel, and Hasskarl.

Folium causonis Rumph. was reduced by Linnaeus to Vitis 

 trifolia Linn, in his Systema, ed. 10 (1759) 942, Sp. PL ed. 2 

 (1762) 293, which, as Cissus trifolia K. Sch., or Columella tri- 

 folia Merr., is the correct disposition of it. Of the various syn- 

 onyms cited above it is the type and whole basis of but one, 

 Cissus acida Murr., but is cited as a synonym in the original 

 description of Cissus carnosa Lam. and of Cissus crenata Vahl. 

 Roemer and Schultes, Syst. 3 (1818) 313, thought that it might
