2. Galla queenslandiensis H. {loc. cit., 

 109). From Queensland, where the in- 

 duced disease was first studied. 



Common name : Sugar-cane dwarf -dis- 

 ease virus. 



Host : GRAM INEAE—Saccharum offi- 

 cinarum L., sugar cane. 



Geographical distribution : Queensland. 



Induced disease: In sugar cane, young 

 leaves marked with scattered chlorotic 

 streaks, leaves stiff and erect, spindle 

 twisted, abnormally short and pale. As 

 leaves mature, streaks disappear, leaves 

 become darker than normal green. In 

 recently infected plants, vascular bun- 

 dles are enlarged, irregular in shape, fused 

 and characterized by abnormal prolifera- 

 tion of thin-walled lignified cells. 



Literature : Bell, Queensland, Bur. 

 Sugar Exp. Sta., Div. Path., Bull. 3, 1932. 



3. Galla anemones H. {loc. cit., 108). 

 From Latin anemone, anemone or wind- 

 flower. 



Common name : Anemone -alloiophylly 

 virus. 



Hosts: RANUNCULACEAE— Ane- 

 mone nemorosa L., vernal windflower; A. 

 ranunculoides L. ; .A. trifolia L. 



Geographical distribution: Germany. 



Induced disease : Leaves thickened and 

 distorted, petioles thickened. Flowers 

 distorted or not formed. Vascular bun- 

 dles larger and more numerous than in 

 healthy plants. Palisade cells short, 

 chloroplasts smaller and fewer than nor- 

 mal. 



Transmission : By needle puncture into 

 rhizomes immersed in filtered juice of dis- 

 eased plant. By contamination of soil 

 with fragments of diseased leaves or 

 rhizomes.

 536; Ztschr. wissensch. Biol., Abt. E,

 1936, 357-370. 



4. Galla verrucae Blodgett. (Phyto- 

 path., S3, 1943, 30.) From Latin verruca, 

 wart. Originally spelled verruca, ap- 

 parently by a typographical error, which 

 was corrected twice on the following page, 

 once in a statement that the genitive ver- 

 rucae had been given as specific epithet. 



Common name : Peach-wart virus. 



Host : ROSACEAE — Primus persica 

 (L.) Batsch, peach. 



Geographical distribution : United 

 States (Idaho, Washington, Oregon). 



Induced disease : In peach, no charac- 

 teristic effect on foliage. Fruits blis- 

 tered, welted, later with warty out- 

 growths conspicuously raised. Affected 

 tissues light tan to red, rough, cracked 

 and russeted, or smooth. Gumming 

 usual, often severe. Warty tissue super- 

 ficial; underlying tissues coarse, filled 

 with gum pockets, but not abnormal in 

 flavor. Warty tissue may be hard and 

 bony, but more often it is merely tougher 

 than normal. 



Transmission : By budding and in- 

 arching. 



Literature: Blodgett, Phytopath., 31, 

 1941, 859-860 (Abst.) ; 33, 1943, 21-32. 



5. Galla zeae McKinney. (Jour. 

 Washington Acad. Sci., 34, 1944, 328.) 

 From Latin sea, a kind of grain. 



Common name : Wallaby-ear disease 

 virus. 



Host: GRAMINEAE—Zea mays L., 

 corn (maize). 



Geographical distribution : South- 

 eastern Queensland, Australia. 



Induced disease: In corn (maize), 

 small swellings on secondary veins on 

 undersides of young leaves, spreading to 

 base and tip of leaf along veins; plant 

 dwarfed, becoming abnormall}' deep green 

 and deficient in development of pollen; 

 silk, cobs, and grain retarded in growth.
