In this paper, the distribution of three species of beech forests, regarding their
position on differently facing slopas and at different elevations, as well as their pollen
distribution, on Fanching Shan situated in Kweichow Province in South-eastern
China is discussed.
It is the fact that (1) Being affected by the air currents of the Pacific Monsoon,
and by its own topographic variation, the difference between the north and south
slopes in its eastern and western flanks reflected on the plant communities by the
humidity-warmth relationships (fig. 2, 3; tab. 2, 3, 4). (2) The patterns of the horizontal distribution of three species in China show that Fagus engleriana has a
northern-most range, F. longipetiolata the southern-most range, while F. lucida is
intermediate between them (fig. 5). (3) From the palynological analysis of the soil
layers, the waxing and waning of the different tendencies of Fagus spp. on different
slopes are rather prominent.
The discussion is made mainly as follows. The relationship between the state of
growth and humidity-warmth conditions is shown (fig. 6). In accordance with the
conditions of the vertical, horizonal and palynological distribution of beeches, we have
tried to present a figure (fig. 7) which shows the waxing and waning tendencies of
three species of Fagus historically, with respect to different slopes. The southern
slope of western flank (Ws) is now in a state moderate growth of Fagus longipetiolata; in the past, there had been a period which saw this beech enjoying a gradual
increase, but later on it began to wane till it reaches the present state. The Wn slope
had seen a gradual increase of Fagus lucida in the historical time (at the same time
there was an accompanying slow increase of F. longipetiolata), till a certain period
when the total number of beech pollen grains decreases gradually in the analysis;
this is followed again by a slight increase, the last increase is apparently due to the
fact that in spite of the decrease of F. lucida, there was a great increase in F. longipetiolata. The two effects combine to make the line of curve to lower rather than
to rise. The Es slope has in its historical past a period when beeches were favoured
with a steady increase, and this tendency is apparently still in progress today,
although it is approaching its culmination. The En slope had seen Fagus engleriana
in a slowly receding tendency, and sees it now almost in the process of being eliminated, to be replaced by F. lucida. Through the explanation given above, we have
thereby an understanding about the relationship between the climatic changes in the
historical time and the waxing and waning of the different beeches in both time andspace.

The Menispermaceae is a well-known alkaloid-rich family within the flowering
plants. Because of the therapeutic value and pharmacological actions of the alkaloids,
contents of its members it has, besides taxonomists also attracted the attention of
chemists, pharmacists and other research workers. In the present work, the menispermaceous medicinal plants of this country are dealt with from their taxonomical, phytochemical and therapeutic aspects.
As a result of our preliminary study, out of 18 genera with some 70 species so
far found in China, 15 genera with 51 species and 2 varieties are known to possess
medicinal value, of which some are famous Chinese drugs, viz. Stephania tetrandra S.
Moore (粉防己), Tinospora callipes Gagnep. (金果榄), Sinomenium acutum (Thunb.)
Rehd. et Wils. (青藤); some are important folk remedies, e.g. Archangelisia loureirii
(Pierre) Diels (古山龙), Stephania cepharantha Hayata (金线吊乌龟); and some are
raw materials for the preparation of medicines, e.g. Fibraurea tinctoria Lour. for
tetrahydropalmatine, Stephania sinica Diels for rotundine, etc.
After a careful taxonomic examination, two new species, Cocculus mokaingensis
Lien, Pericampelos omeiensis Lien, are found and herewith discribed.
Isoquinoline alkaloids are widely distributed in the whole family. The Trib.
Aniamirteae consisting of genus Arcangelisia, the Trib. Fibraureae consisting of
genera Tinomiscium and Fibraurea, as well as the Trib. Tinosporeae consisting of
genera Tinospora and Parabaena are charaterized by the presence of proberberine
alkaloids, e.g. berberine, palmatine, jatrorrhizine, columbamine, etc. and such
alkaloid-bearing plants are commonly used as antiperiodic, antidote, antibiotic, antimalarial, etc. On the other hand, the Trib. Menispermeae elaborates mainly
bisbenzylisoquinoline-type alkaloids, and these plants are usually used in the treatment
of rheumatism, and often as an anodyne, diuretic etc. To facilitate identification, 10 plates are here provided.
