RUMPHIUS'S HERBARIUM AMBOINENSE 



Filix lanuginosa Rumph. Herb. Amb. 6: 69. 



From the description the plant must be Cibotium baranetz J. Sm. or 

 Dicksonia sorbifolia Sm., as suggested by van Alderwerelt van Rosenburgh. 

 A future exploration of Amboina will doubtless yield material by which its 

 status can be definitely determined. 

 Filix canarina Rumph. Herb. Amb. 6: 64. 



Indeterminable from the data and the material at present available.

 Olus calappoides Rumph. Herb. Amb. 1: 86, t. 22, 23. 

 Olus calappoides II e Celebes Rumph. 1. c. 87, t. 20, 21. 



Amboina, Wae, Robinson PI. Rumph. Amb. 563, November 29, 1913, in 

 light forests near sea level, staminate, locally known as sayor kalappa. 



The specimen represents Olus calappoides mas Rumph. Herb. 

 Amb. 1 : 99, t. 23. Possibly more than one species is represented 

 by the plants described and figured by Rumphius, but more 

 abundant material and a critical study of all the Indo-Malayan 

 forms allied to Cycas circinalis Linn, will be necessary definitely 

 to settle this point. The Rumphian illustrations are as follows : 

 t. 20 represents an oblong-ovoid staminate inflorescence with 

 leaves, poor ;t. 21, a habit sketch of the same ; t. 22, a habit sketch 

 and female inflorescence and infructescence, fairly good; and 

 t. 23, a habit sketch with an elongated staminate inflorescence. 



It is by no means certain that Cycas rumphii Miq. is specifically- 

 distinct from C. circinalis Linn. The latter should be interpreted 

 by Ceylon and Indian specimens, although in the orginal descrip- 

 tion Linnaeus gives two references to Amboina figures and de- 

 scriptions, including Olus calappoides Rumph. Herb. Amb. 1 : 86, 

 t. 22, 23. In Stickman, Herb. Amb. (1754) 6, and in Amoen. 

 Acad. 4 (1759) 119, t. 21 to 23 are included. Loureiro, Fl. 

 Cochinch. (1790) 632, cites all four figures under Cycas inermis 

 Lour., a species that must be interpreted from specimens from 

 southern China and Cochin-China ; it is supposed to be the same 

 as Cycas revoluta Thunb., but Loureiro's description of the leaves 

 does not conform with Thunberg's species. Blume, Rumphia 4 

 (1848) 14, refers Lagolo Rumph. Herb. Amb. 1: 87, t. 22, B, to 

 Cycas thouarsii R. Br., a species of eastern Africa and Madagas-
