476 RUMPHIUS'S HERBARIUM AMBOINENSE 



PSEUDERANTHEMUM RACEMOSU M (Roxb.) Radlk. ex Lindau in Engl. 



& Prantl Nat. Pflanzenfam. 4 ,b (1895) 330. 

 Eranthemum racemosum Roxb. Hort. Beng. (1814) 3, nomen nudum, 

 Fl. Ind. ed. 2, 1 (1832) 113. 

 , 0!us caprinum Rumph. Herb. Amb. 6: 54. 

 Amboina, Amahoesoe, Robinson PI. Rumph. Amb. 95, August 30, 1913, 

 along roadsides at low altitudes, flowers pale purplish. 



No previous identification of Olus caprinum Rumph. has been 

 suggested, other than Hasskarl's reference of it to the Acan- 

 thaceae. The specimen cited above agrees very closely with 

 Rumphius's description and even better with that of Roxburgh. 

 The type of Eranthemum racemosum Roxb. was from the 

 Moluccas. 



PERISTROPHE Nees 



PERISTROPHE BIVALVIS (Linn.) comb. nov. 



Justicia bivalvis Linn. Amoen. Acad. 4 (1759) 134, Syst. ed. 10 



(1759) 850 (type!). 

 Justicia tinctoria Roxb. Fl. Ind. 1 (1820) 124. 

 Peristrophe tinctoria Nees in Wall. PI. As. Rar. 3 (1832) 113. 

 Folium tinctorium Rumph. Herb. Amb. 6: 51, t. 22, f. 1. 

 Amboina, Soja and Koesoekoesoe sereh, Robinson PI. Rumph. Amb. 98, 

 August, 1913, in light woods, altitude 200 to 400 meters. 



The synonymy of this species is especially complicated, but 

 Justicia bivalvis Linn, as originally published, not as currently 

 interpreted in modern botanical literature, is clearly based wholly 

 on Folium tinctorium Rumph. and nothing else. In Stickman's 

 Herb. Amb. (1754) 26, Linnaeus erroneously referred it to 

 Jussiaea [sic!] purpurea Linn., a manifest error for Justicia 

 purpurea Linn., this species having been based on specimens 

 collected by Osbeck in China. In Amoen. Acad. 4 (1759) 134 

 it appears thus: "22 Folium tinctorium= Justicia bivalvis/' 

 clearly indicating from the cited name, Folium tinctorium, that 

 t. 22, f. 1, was indicated. However, in the same year, Linnaeus 

 published Justicia bivalvis with a short description, Syst. ed. 

 10 (1759) 850, with an erroneous reference to "Rumph. VI. 

 t. 29," which is a fern, Athyrium esculentum Copel; the descrip- 

 tion unmistakably applies to Folium tinctorium Rumph. from 

 which it was apparently taken. In the same place Linnaeus 

 erroneously referred t. 22, f. 1 {Folium tinctorium) , to Justicia 

 purpurea Linn., following his first treatment of it in Stickman's 

 Herbarium Amboinense. Again, Sp. PL ed. 2 (1762) 23, Lin- 

 naeus referred to Justicia purpurea the Rumphian Folium tinc- 

 torium Herb. Amb. 6: 51, t. 22, f. 1, and on the same page he 

 referred to Justicia bivalvis the Rumphian Bungum Herb. Amb.
