102 REV. M. J. BERKELEY ON SOME TUBERIFORM 
On some Tuberiform Vegetable Productions from China. 
By the Rev. M. J. Brzgxzy&y, M.A., F.LS. 
[Read April 15th, 1858.] 
Some months since I received, by the kindness of Professor Hora- 
ninow, two tuberiform productions from China, of which one was 
nearly allied to Mylitta australis, Berk., and the other, marked 
Pachyma Coniferarum, Horaninow, was evidently identical with 
the Tuckahoe or Indian Bread of the United States, Pachyma 
Cocos, Fries. 
At a later period, specimens of a drug, known in China under 
the name of Pe-foo-ling, were shown by Mr. Daniel Hanbury to 
Mr. Kippist, who at once pointed out their identity with Lyco- 
perdon solidum of the * Flora Virginica,’ Pachyma Cocos, Fries. 
The subject was brought to my especial notice by Dr. Hooker ; 
and having ascertained the identity of the productions of Mr. 
Hanbury апа Prof. Horaninow, I thought that a short note on it 
might possibly be acceptable to the Society ; and the more во, as 
Mr. Hanbury has а second production very nearly allied, while I 
am in possession of a third very distinct though allied substance, 
through Prof. Horaninow. 
The best introduction to my note will be an extract from 4 
letter received by me from Mr. Hanbury :— 
“There are two Chinese esculent Fungi, which I think are 
worthy of notice. My attention was first drawn to them while 
examining some specimens of Chinese Materia Medica, by stum- 
bling on the following passage in Loureiro’s ‘Flora Cochin- 
chinensis’ (ed. Willd. 1798, p. 710) :— 
* * Ad radices Pinorum sylvestrium magne longeevitatis in pro- 
vincia boreali Chinensi Su chuyen gigni solent qusdam tubera, 
subrotunda, magna, scabra, fusca, intus albissima, que ab Europeis 
vocantur Radix Sinensis alba, a Cochinchinensibus Bach phuc linh, 
ab ipsis vero Sinensibus Р? fú Ип. Horum tuberum decocto fe- 
liciter utuntur in praxi medica, precipue in morbis pulmonum et 
vesice. 
“ ¢ Radix Sinensis rubra provenit ex diversa planta, que а Lin- 
næo dicitur Smilax China.’ 
“Nor was my curiosity diminished by finding in Endlicher’ 8 
* Enchiridion Botanicum’ (р. 144) the following allusion to the 
same subject :— 
**In annosis Pinus Massoniane Lamb. radicibus apud Sinas . 
gigni solent tubera (vulgo Pe-fu-lin, Radix Sinensis alba) magna,
