122 PENGHAWAR DJAMBI. 



isse. O f Kaulfuss, and in my Genera Filicum, published in 1841, 

 I recorded it under the name of Cibotium Barometz. 



" In the Berlin Garden it received the name of G. glaucophyl- 

 lum, afterwards changed to G. glaucescens by Kunze, who figured 

 it in Schukhr's Supplement, p. 63, t. 31. Since then (1846) 

 dried specimens collected both by Fortune and by Seemann, 

 and corresponding with the living plant, have been received from 

 China. 



"Now for the name Cibotium Oumingii. In 1840, Cuming 

 brought specimens of a Cibotium from the Philippines, which in 

 my enumeration of the ferns of those islands I named Cibotium 

 glaucum? then believing it to be the Dicksonia glauca of Dr. J. 

 E. Smith (Kee's Cyclop., vol. xi.). Kunze, however, considered it 

 a distinct species and named it C. Cumingii. 



Cibotium " After much examination of well- authenticated specimens I 

 Barometz. have come to ^ Q conclusion that C. Barometz, J. Sm., G. 

 glaucescens, Kunze, G. Cumingii, Kunze, and G. Assamicum, Hook., 

 constitute one species only. I therefore retain the original 

 historical name of C. Barometz for the eastern type of the 

 genus. 



" It appears that the stipes called Pengliawar Djambi comes 

 from Sumatra. Although I have npt seen any fronds of 

 Cibotium from that locality, still, judging from the stipes in 

 question, I see no reason to doubt the correctness of referring 

 it to Cibotium Cumingii, which, as above stated, I regard as not 

 different from C. Barometz" 



Agnus The authors of the Pharmacopoea Neerlandica quote Agnus 

 Scytiucm. ^ C y^ l { cus as synonymous with the Sumatran Penghawar Djambi, 

 in which it is evident Mr. John Smith thinks them correct. 

 They do not, however, attempt to fix the botanical origin of 

 the drug, but merely refer it to " Filicis species nondum satis 

 cognita." 



Professor Miquel, on the other hand, while referring Penglia- 

 war to C. Cumingii, Kunze, questions its identity with Agnus 

 Scythicus in these words : " Agnus Scythicus seu Barometz 

 pJiarm., filicis etiam caudcx est sed ab eo Cibotiorum 

 diversus." 2
