might be Laportea stimulans Miq. No. 310, cited above under 

 Laportea amplissima Miq., was considered by Doctor Robinson 

 certainly to represent Folium urens rubrum Rumph., and if 

 this be correct, then this form described by Rumphius becomes 

 a synonym of Laportea amplissima Miq. The leaf measure- 

 ments given by Rumphius for all three forms are matched by 

 some of the leaves on the specimens cited above. 



LAPORTEA DECUMAN A (Roxb.) Wedd. Monogr. Urt. (1856) 127. 



Urtica decumana Roxb. Hort. Beng. (1814) 67, nomen nudum, Fl. 



Ind. ed. 2, 3 (1832) 587. 

 Urtica rumphii Kostel. Allgem. Med.-Pharm. Fl. 2 (1833) 400 (type!). 

 Urtica decumana Rumph. Herb. Amb. 6: 47, t. 20, f. 1. 



Amboina, Halong and Hitoe lama, Robinson PL Rumph. Amb. 316, Sep- 

 tember and October, 1913, along streams and in forests from near sea 

 level to an altitude of 250 meters, locally known as daun gattal puti and 

 daun gattal mera. 



This was originally reduced by Linnaeus, through error, to 

 Urtica interrupta Linn., in Stickman Herb. Amb. (1754) 2G, 

 Amoen. Acad. 4 (1759) 134. It has been cited by several 

 authors under Fleurya interrupta Gaudich., but the figure does 

 not pertain to this species, and the description only as to Urtica 

 decumana III vulgaris; see below. Roxburgh cites the Rumphian 

 description and figure in the original description of Urtica 

 decumana Roxb., which was based on specimens introduced into 

 the Calcutta Botanic Garden from the Moluccas. The Rumphian 

 figure and description are the basis of Urtica rumphii Kostel. 

 The figure is exceedingly poor, but it manifestly belongs with 

 this species rather than with Fleurya interrupta Gaudich. I 

 consider that the forms described by Rumphius as I alba and II 

 rubra represent Laportea decumana (Roxb.) Wedd. as here 

 interpreted.

FLEURYA INTERRUPTA (Linn.) Gaudich. Bot. Freyc. Voy. (1826) 497. 



Urtica interrupta Linn. Sp. PI. (1753) 985. 



Urtica decumana III vulgaris Rumph. Herb. Amb. 6: 48. 



Amboina, Robinson PI. Rumph. Amb. 319, July 19, 1913, in waste places, 

 town of Amboina, locally known as daun gattal. 



There is very little doubt as to the correctness of this reduction 

 of Urtica decumana vulgaris Rumph. The other plants de- 

 scribed in the same chapter, Urtica decumana alba and rubra,, 

 are apparently both Laportea decumana Wedd.
