and sorghums. Besides Teff grass, Sudan, Kikuyu (Pennisetum longistylum), Toowoomba 

 grass {Phalaris bulbosa), and Napier or Elephant grass {Pennisetum pur-pur eum) do quite 

 well. Among the most important of what may be called the minor agricultural grasses in 

 South Africa are Paspalum dilatatum (Water grass), Paspalum virgatum (Erect Paspalum), 

 Festuca arundinacea (New Zealand tall Fescue), Festuca ovina (Italian Fescue), Dactylis 

 glomerata (Cocksfoot), Lolium mutiflorum (Italian rye grass), and Chloris gayana (Rhodes 

 grass). Blaauwzaad grass (Chloris virgata) has done well in parts of the Orange Free State 

 and in the Transvaal. Root crops are grown under irrigation, and Kaffir melons, pumpkins, 

 ground nuts, artichokes, sunflowers, and velvet beans are grown to some extent. Tepary 

 beans, Kudzu, and Mung beans have recently been introduced and seem worthy of attention. 

 The chief winter crops are the grains, rape, vetches, and peas. — A. J. Pieters. 



1603. McDonald, A, H. E. Cutting Sudan grass for seed. Agric. Gaz. New South 

 Wales 32 : 85. 1921 . — In New South Wales best results are secured when the 2nd or 3rd growths 

 are cut for seed. Binders are used for harvesting. — L. R. Waldron. 



1604. Maiden, J. H. Chats about the prickly pear. No. 9. Agric. Gaz. New South Wales 

 32: 97-104. 4 fig. 1921. — The author discusses Opuntia aurantiaca, 0. elatior, 0. inermis, 

 0. tomentosa, O. ficus-indica, 0. robusia, 0. monacantha, 0. Dillenii, and 0. cochinillifera as 

 noxious weeds. Distribution, taxonomy, and morphological characters of the species are 

 considered. — L. R. Waldron. 



1605. MiTNDY, H. G. Kudzu vine. (Pueraria thunbergiana). Rhodesia Agric. Jour. 18: 

 83-88. Fig. 1-2. 1921. — Kudzu, an extremely promising legume, has been grown at the 

 Salisbury experiment station sitice 1918. It makes an early spring growth, and gives a heavy 

 yield of nutritious fodder, apparently palatable either green or dry for all classes of stock. 

 Kudzu produces root nodules freely and leaves a large amount of decaying vegetable matter 

 on the land; consequently, it should be valuable as a soil renovator. — Mary R. Burr. 



1606. MuNDY, H. G. Wheat in Rhodesia. Rhodesia Agric. Jour. 17: 501-512. 6 fig. 

 1920. — The present annual consumption of wheat in southern Rhodesia is some 31,000 bags 

 in excess of production. The paper discusses cultural methods for wheat growing, varieties, 

 harvesting and threshing, and diseases and pests. Summer wheat cannot be grown because 

 of rust; winter wheat may sometimes suffer from rust, but not seriously. Some work has 

 been done in selection of resistant varieties but so far with no permanent success. Smut 

 is prevalent and seed treatment is urged. Deaf ear or white ear is caused by frost at blossom- 

 ing time. This can be prevented by seeding at such a time that the plant does not bloom until 

 after frost or by grazing to retard the maturity of the plant.— J.. J. Pieters.

 [Fertilizer experiments with magnesia-free and magnesia-containing potash salts.] Mitteil.

 chloride failed to increase the yield of potatoes in this experiment, although on the same 

 field, but in another experiment, potassium sulphate produced a large increase in yield. —

 Peletjs. Contribution to Greek cereology. Part 1, wheat.] 139 p. Athens, 1919. — A short 

 treatise, or monograph, dealing with the cultivated kinds of wheat in all of the different parts 

 of Greece, with a brief introduction on selection, breeding, the cereology of ancient 

 Greece, and the importance of wheat cultivated in modern Greece. The native varieties 

 especially adapted to the climatic conditions of Greece are examined and information as to 

 yield, time of sowing, soil and rainfall requirements are fully discussed. The species of 

 wheat, Triticum polonicum, T. durum, T. turgidum, T. sativum, T. spelta, T. amyleum, and 

 T. monococcum are discussed and illustrated. A table of the main species of wheat with their 

 most important varieties is included. A bibliography is also given. — Geo. Bouyoucos.
