The form, structure, and behavior of the fungus indicate that it belongs to 

 the genus Actinomyces. 



An extended bibliography is appended. 



Botrytis as a parasite upon chrysanthemums and poinsettias, P. Spaulding 

 {Mo. Bot. Gard. Ami. Rpt., 21 {1910), pp. 185-188, pi. i ) .—Attention is called to 

 the attaclis of this fungus {B. vulgaris) on flowers of chrysanthemums, on the 

 lower leaves of poinsettias {Euphorbia pulcherrima) , and of Primula ohconica 

 grandlflora in the greenhouses of the Missouri Botanical Gardens at St. Louis. 



On chrysanthemums the disease first appeared as tiny, watery, discolored 

 spots on the petals, loolving as if they had been pricked with a needle. The dis- 

 eased areas spread rapidly in size until about one-fourth of the petal was 

 affected, after which the diseased tissues wilted and dried up. Later '.he 

 characteristic fruiting bodies of B. vulgaris appeared on the wilted petals. 



On the poinsettias the fungus first attacked the slightly projecting angles of 

 the lower leaves of the plants, causing a small, deadened area at the very tips 

 of the angles, while on the lower surface, extending along the larger veins, tiny 

 white drops of the hardened latex could be seen. These small, hardened drops 

 of juice seemed to be very characteristic of this disease upon the poinsettias. 

 As the disease progressed, the affected areas became larger and the extreme tips 

 of the affected angles withered and became discolored. When about one-fourth 

 of the leaf surface was involved the leaf was prematurely shed, leaving, for 

 badly diseased plants, a bare stem with a broad whorl of red leaves at the top. 

 About two days after the leaves were first attacked, Botrytis spores were found 

 in thick groups on the surface of the affected areas. 



Limewater Bordeaux for spraying', D. McAlpine {Jour. Dept. Agr. Victoria, 

 8 {1910), A'O. 2, pp. 728-732, figs. 2).— A Bordeaux spray consisting of 10 oz. of 

 copper sulphate, SJ gal. of limewater, and water to make up the 50 gal., is recom- 

 mended in place of the usual Bordeaux mixture. 



It is claimed that this limewater Bordeaux mixture is cheaper and quicker 

 acting than the ordinary Bordeaux. Experiments conducted in 1908 on apple 

 black spot {Fusicladium dendriticum) showed that it was also as efficacious in 

 preventing that disease.
