Perticaria tertia latifolia Rumph. Herb. Amb. 3: 189. 

 Amboina, Negri lama, Robinson PI. Rumph. Amb. 279, September 8, 1913, 

 in light woods, altitude 10 meters, locally known as hunot; Amboina (town), 

 Robinson PI. Rumph. Amb. 278, July 30, 1913, river sides at 5 meters 

 altitude, locally known as morong itam; Paso, Robinson PI. Rumph. Amb. 

 280, near the seashore, October 29, 1913, locally known as morong mera and 

 hunut puti. 



There is very little doubt that the three Rumphian descrip- 

 tions, cited above, represent the same species, and that all 

 are Columbia (Diplophr actum) subobovata Hochr. The species 

 presents great variation in its vegetative characters, the leaves 

 varying from 8 to 35 cm in length and from 5 to 18 cm in width, 

 all intermediate sizes being found on the same specimen. Like- 

 wise the leaf bases on the same specimen vary from perfectly equi- 

 lateral to strongly inequilateral. The figure given by Rumph- 

 ius for Perticaria tertia is very poor, and one would never 

 suspect that it was intended for a species of Columbia. The 

 description, however, is unmistakable. Loureiro, Fl. Cochinch. 

 (1790) 639, referred, with doubt, Restiaria nigra Rumph., Herb. 

 Amb. 3: 188, to Restiaria cor data Lour. Loureiro's species, how- 

 ever, is supposed to be an Uncaria, is certainly not the same as 

 the Rumphian one, and must be interpreted from Cochin-China 

 material. The proper disposition of Perticaria has not before 

 been indicated.*

Amboina, town of Amboina and Gelala, Robinson PL Rumph. Amb. 277, 

 August, 1913, along the beach and in waste places at low altitudes. 



Lappago amboinica Rumph. Herb. Amb. 6: 59, t. 25, f. 2, is 

 certainly Urena lobata Linn. The figure is poor, but the drawing 

 of the fruits and the description are unmistakably Urena, while 

 the drawing of the flowers on the same plant are likewise
