2. — Caragana microphylla Lam. It grows on all Man- 

 churian mountainous districts and also is a shrub with 

 plumose leaves and yellow flowers. It is used in medicine 

 like the first one. 



3. — Funkia ovata Spreng. It is found wild in Kirin pro- 

 vince and is cultivated in the Far East and in North China. 

 Funkia is a perennial plant with broad oval shaped leaves and 

 blue flowers. The medicinal use of it is identical with the 

 Funkia subcordata (see Stuart page 180). 



4. — White misletoe (Viscum album L.). It is a common 

 parasitic plant found upon the poplar, willow, aspen, linden, 

 birch, apple trees with white and red berries (Suhsp. cora- 

 latmu Komarow.) This plant is used in Chinese medicine 

 and by natives of Ussuri provinces. The entire plant is used 

 by them against rheumatism. 



5. — Astragalus membranaceus Fischer, (see Stuart — 

 Astragalus Hoangtchy, page 57). This plant grows in all 

 parts of the country and represents a big perennial with a 

 branchy stalk and numerous pale-yellow flowers. This 

 common Chinese drug now is collected in great quantity and 

 exported to China. 



6. — Velvet or velvet-tree 6 (Phellodendron amurense 

 Rupr. (see Stuart page 316). This tree, common in all 

 districts, is not very often employed here and is not well 

 known.

 mon perennial plant growing in all parts of Manchuria with 

 a stalk 1 meter high, with sharp lancet leaves and white 

 flowers collected in wrists. The thick, straight or branchy 

 roots are used in Chinese medicine. 



X. — Some Observations on the Growth of Weeds 

 and Algae in Eice Fields at Foochow. 



Eice fields are favourable places for observing the con- 

 ditions of life of many plants. The biological analysis of 

 the water in the rice fields undoubtedly can be of large 

 practical utility in explaining many questions connected with 

 the manure in the ground of the rice fields and condition of 

 the water. As would be expected the life in rice fields 

 resembles very much the life in the grass marshes of Western
