RUMPHIUS'S HERBARIUM AMBOINENSE 



Rumphius's description of Hoelen was based on material 

 originating in China. It is the whole basis of Pachyma hoelen 

 Fries and, like Pachyma tuber regium Fries, is of doubtful status. 

 It is cultivated on pine trees in various parts of China*" and 

 has been referred to Pachyma cocos Fries. Specimens of fulin, 

 kindly secured for me by Mr. W. J. Tutcher in a Chinese drug 

 store in Hongkong, agree closely with the excellent figures of 

 Pachyma cocos Fries given by Currey in Trans. Linn. Soc. 23 

 (1860) t 10, f. 5, 6, 9. A part of Mr. Tutcher's specimen was 

 sent to Dr. W. A. Murrill, of the New York Botanical Garden, 

 who states that he has sclerotia of the same general type from 

 different localities in America, but that the only method of 

 distinguishing them accurately is to develop the fruiting form. 

 In some cases the fruiting form proves to be species of Polyporus, 

 in others species of Lentinus. He expresses the opinion that 

 Pachyma hoelen Fries is distinct from P. cocos Fries. 



FUNGUS indet. 



Muscus frutescens III muscagineus Rumph. Herb. Amb. 6: 87. 



The description apparently applies to the mycelium of some 

 fungus, but the status of Muscus frutescens muscagineus is 

 wholly indeterminable. 



LICHENES 

 USNEA Linnaeus 



USNEA sp. 



Barba saturni Rumph. Herb. Amb. 6: 88. 



Henschel thought that this might be a species of Lycopodium, 

 which is an impossible reduction of it. Hasskarl, Neue Schlussel 

 (1866) 167, states (( Usneae aut gen. aff. Lichenum spec, qua- 

 edam." The form described is probably an Usnea. 



USNEA sp. 



Muscus capillaris Rumph. Herb. Amb. 6: 89, t. 40, f. 2. 



Linnaeus, in Stickman Herb. Amb. (1754) 27, Amoen. Acad. 

 4 (1759) 135, Syst. ed. 10 (1759) 975, erroneously reduced this 

 to Renealmia usneoides Linn., which is the American Tillandsia 

 usneoides Linn., of the Bromeliaceae. Burman f., Fl. Ind. (1768) 

 239, cites it under Lichen capillaris Burm. f ., of which, however, 

 it is scarcely the type. Loureiro, Fl. Cochinch. (1790) 171, dis- 

 cusses it under Grammica aphylla Lour. =Cuscuta chinensis Lam. 

 and definitely refers it, op. cit. 687, to Lichen usnea Linn. 

 Rumphius's description perhaps includes more than an Usnea,
