RUMPHIUS'S HERBARIUM AMBOINENSE 



but the description does not conform to Crataeva in the seed 

 characters : "In centro quatuor vel quinque locantur ossicula, a 

 sese invicem remota, lanosa seu pilosa instar seminum Gossypii." 

 In the original description Rumphius states that the flowers 

 were unknown to him; but in the plate, drawn after he became 

 blind, the flowers are shown. His original material was from 

 Manipa, Sula Islands, and Celebes, but in the supplementary 

 data taken from the Auctuarium and appended to the original 

 description he cites specimens from Leytimor, Amboina, and 

 states regarding the fruit : "Fructus est instar ovi minoris avis 

 Casuarii." It is possible that the description was based on 

 material from two different species. The figure, however, con- 

 forms to the characters of Bilacus amboinensis silvestris as 

 given in the text. In some respects the figure and description 

 suggest Chaetospermum, typified by the Philippine Chaetosper- 

 mum glutinosum (Blanco) Swingle, but Bilacus amboinensis 

 silvestris Rumph. can hardly belong in the Rutaceae.

Loureiro, Fl. Cochinch. (1790) 467, first reduced Limonellus 

 madurensis to his Citrus madurensis, which Swingle considers 

 to be a synonym of Citrus japonica Thunb. =Fortunella japonica 

 Swingle. The plant is a native of China, and the only possible 

 objection I note to the reduction of Limonellus madurensis is 

 that Citrus japonica is not known to occur in the Malay Archi- 

 pelago. However, Rumphius states that the plant was cultivated 

 in Madura and at Batavia, Java, where it may have been intro- 

 duced from China and where it has failed to persist. Hasskarl, 

 Neue Schlussel (1866) 32, suggests Atalantia monophylla DC. 

 as the proper reduction of Limonellus madurensis Rumph., but 

 judging from the figure and description given by Rumphius the 

 plant can hardly have been an Atalantia.
