RUMPHIUS'S HERBARIUM AMBOINENSE 



specimens collected in Amboina by Teysmann and DeVriese. 

 In his Revisio critica Casuarinarum (1848) 282 and in his Flora 

 Indiae Bataviae l 1 (1858) 873, Miquel erroneously referred Ca- 

 suarina montana Rumph. to Casuarina nodiflora Forst. The 

 species is a characteristic one of the mountain forests of the 

 Philippines and of the Moluccas. 



CASUARINA EQUISETI FOLIA Linn. Amoen. Acad. 4 (1759) 143 (type!) 

 (equisefolia) ; Forst. Char. Gen. (1776) 103. t. 52. 

 Casuarina litorea Rumph. Herb. Amb. 3: 86, t. 57. 



This widely distributed and well-known species is not repre- 

 sented in our Amboina collections. Rumphius's figure is an 

 excellent one, and there is no doubt whatever as to the correctness 

 of this reduction, which was originally made by Linnaeus; in 

 fact Casuarina litorea Rumph. is the type of Casuarina equiseti- 

 folia Linn, as published in Amoen. Acad. 4 (1759) 143, although 

 the species is usually accredited to Forster (1^76). 



CASUARINA SUMATRANA Jungh. in Hoev. & DeVriese Tijdschr. 11 

 (1844) 115. 



Casuarina celebica Rumph. Herb. Amb. 3: 87, t. 58 f. A. 



This disposition of Casuarina celebica follows Miquel and is 

 certainly correct. The species is well characterized by its re- 

 latively large fruits.

* I am under obligations to Mr. C. de Candolle, Geneva, Switzerland, 

 for determinations of the Piperaceae collected by Doctor Robinson. In 

 all but two cases the specimens are here quoted under the binomials indi- 

 cated by him, the exceptions being Piper decumanum Linn., reported as 

 P. forstenii C. DC., and Piper arborescens Roxb., reported as P. miniatum 

 Blume, the specific name adopted by me being accepted as the oldest valid 

 one in each case. The determinations of the Rumphian species are by 

 Doctor Robinson and myself.
