RUMPHIUS'S HERBARIUM AMBOINENSE 



I am unable definitely to place the forms very briefly described 

 by Rumphius under Empetrum acetosum II rubrum and III cordatum. 

 The former Hasskarl, Neue Schliissel (1866) 146, thought might 

 be referable to Begonia (Diploclinium) rubrum Blume and the 

 latter to Begonia mollis A. DC. It seems probable that Em- 

 petrum acetosum II rubrum was merely a broad-leaved form of 

 E. acetosum I album=Begonia tuber osa Lam., but E. acetosum 

 III cordatum, described , as pilose, probably represents an en- 

 tirely different species, not, however, represented in our Am- 

 boina collections. 



CACTACEAE 



OPUNTIA Tournefort 



OPUNTIA sp. 



Ficus indica Rumph. Herb. Amb. 4: 89. 



The description is very imperfect, but probably applies to 

 Opuntia. Hasskarl, Neue Schliissel (1866) 80, thought that 

 it might be Opuntia dillenii Haw. 



THYMELAEACEAE 



GYRINOPSIS Decaisne 



GYRINOPSIS BRACHYANTHA Merr. in Philip. Journ. Sci. 7 (1912) 

 Bot. 313. 



Cortex filarius Rumph. Herb. Amb. 7: 13. 



Amboina, Way uri, Robinson PL Rumph. Amb. 27U, September 9, 1913, 

 in forests, altitude about 100 meters, locally known as melowassi. 



The specimen of melowassi is in fruit, but is apparently iden- 

 tical with the Luzon species described by me as Gyrinopsis 

 brachyantha. It differs from G. cumingiana Dene, not only in 

 its shorter flowers, but also in the venation of its leaves, all the 

 veins being slender and indistinct, the primary not more prom- 

 inent than the secondary ones. Hasskarl, Neue Schliissel 

 (1866) 186, cites Cortex filarius as a synonym of Anassera mo- 

 luccana Pers. and of A. rumphii Span.; but Persoon, Syn. 1 

 (1805) 265, and Lamarck before him, under Anasser moluccana 

 Lam., 111. 2 (1797) 40, cites not Cortex filarius Rumph. but Cortex 

 foetidus Rumph. Herb. Amb. 7: 12, t. 7, which is a Pittosporum. 

 The correct status of Cortex filarius Rumph. has not been 

 previously indicated. The genus Gyrinopsis has been reported 

 only from the Philippines, but apparently also occurs in Borneo.
