Abstract:

 Bei-mu (贝母), the bulbs of some fritillaries, is one of the most popular drugs
used in China ever since the ancient times.  It is prescribed principally in coughs
and fevers.  In recent years, although much chemical and pharmaceutical investiga-
tions of this drug have been made, its botanical origin remains confused.  Several
types of commercial drugs Bei-mu, for instance, were incorrectly considered by some
authers as being derived from the bolbs of Fritillaria roylei Hook., a species of Kashmir
and Kumaon, not yet found in China.  In the present paper, the writers attempt to
give a revision of the genus Fritillaria of China as well as of commercial drugs sold
on the chinese market under the name of Bei-mu, based on both plant and drug speci-
mens collected from 18 provinces and autonomous regions.
     As a result of our study, twenty species, including two varieties, of Fritillaria of
China are recognized, of which four, F. crassicaulis S. C. Chen, F. omeiensis S. C.
Chen, F. unibracteata Hsiao et K. C. Hsia and F. hupehensis Hsiao et K. C. Hsia,
and one variety, P. thunbergii Miq. var. chekiangensis Hsiao et K. C. Hsia, are de-
scribed as new.  They all, except two species, viz. F.  maximowiczii Freyn  and F.
davidii Franch., are known to possess medicinal value, from which different kinds of
commercial drugs Bei-mu are derived.  These drugs are usually named for the places
where they come from.  The first, called Zhe-bei (浙贝), F. thunbergii Miq., is obtained
from Chekiang and Kiangsu, the second, called Ping-bei (平贝), F. ussuriensis Maxim.,
from northeastern China, the third, called Lu-bei (炉贝), F. delavayi Franch., from
southwestern China, the fourth, called Chuan-bei (川贝), including F. cirrhosa D. Don,
F. unibracteata Hsiao et K. C. Hsia, F. przewalskii Maxim. etc., from Szechuan and
its neighbouring provinces, and the fifth, called Yi-bei (伊贝), including F. pallidiflora
Schrenk, F. karelinii (Fisch.) Baker, F. walujewii Rgl. etc., from Sinkiang. Occasio-
nally, the tubers of Bolbostemma paniculatum (Maxim.) Franquet, the corms of Iphi-
genia indica Kunth and the bulbs of Lloydia  tibetica  Baker  and  Cyanotis  vaga
 (Lour.) Roem. et Schult. are also called Bei-mu in some local drug markets.  They
are different not only in medicinal property but also in appearance from our tradi-
tional genuine commercial drugs Bei-mu as stated above.  They are apparently adul-
terants.
      Detailed accounts about the plants and drugs are given in the text. There are also
provided keys and illustrations which, we believe, will afford facilities for identifica-
tion.
