tation is credited to Chang Chung-ching (2) which names the 
plant Shui Lang-tang (water Lang-tang). The two quotations 
are so similar that they are clearly referable to the same plant 
and perhaps derived from the same source. As it is described as 
a semi-aquatic species with shiny leaves, the plant in question 
is more likely a species of Ranunculus rather than a Solanace- 
ous plant related to Hyoscyamus. Read (1936) gives Ranun- 
culus acris L. var. japonicum Maxim. as a deliration. 
Fang-féng — Siler divaricatum Benth. & Hook.? 
Fang-féng is a drug generally identified as an Umbelliferous 
plant, Siler divaricatum Benth. & Hooker. However, it could 
be possibly referable to some species of Peucedanum. The root 
of the plant is regarded in herbals as an antidote for aconite 
poisoning and as a remedy for curing many types of rheuma- 
tism and debility. The leaves, flowers, and seeds are also used 
for some purposes. 
It is not certain whether the drug actually causes hallucino- 
genic effects or not as there is only one sketchy reference 
referring to this. T’ao Hung-ching (5) was purported to say that 
‘‘The root is spicy and non-poisonous. The kind that bifurcates 
at top produces madness. The kind that bifurcates at the bot- 
tom causes reversion of old ailments.’’ This quotation was 
given in Li Shih-chén (22) without any substantiation or 
additional explanation. 
Lung-li — Nephelium topengii (Merr.)Lo? 
There is only one reference to the plant Lung-li having hal- 
lucinogenic effects. This is in Fang Chéng-ta (18) of the South- 
ern Sung dynasty, subsequently cited in the imperial commis- 
sioned pharmacopeia by Liu Wén-tai et al. (21) and by Li 
Shih-chén (22). ‘‘Lung-li grows in Ling-nan (Kwangtung pro- 
vince). The shape [of the fruit] is like a small Lychee with the 
flesh tasting like Longan. The body and foliage of the tree are 
also similar to these two fruit trees so it is called Lung-li. It 
blossoms in the third month with small white flowers. The fruit 
ripens at the same time with Lychee which cannot be eaten raw
