TUUP BMQHT. 



A bulletin has just been published 

 hy the experiment station at Cornell 

 University on a severe disease of tu- 

 lips. The disease is prevalent in this 

 country and, in many cases, it does 

 much damage. The author of the bulle- 

 tin, E. F. Hopkins, now at the Missouri 

 station, made a thorough study of the 

 disease and in order that the results 

 of his studies, as embodied in the bulle- 

 tin, which is largely technical, ma^ be 

 available to florists, I present below 

 some of the essential facts. 



The disease was first discovered in 

 Europe, where it exists apparently 

 wherever tulips are grown. In this 

 country it was first noted in Xew Jer- 

 sey, in 1902, and, from all indications, 

 was brought into this country by means 

 of a shipment of bulbs from Holland. 

 At the present time the disease is wide- 

 spread throughout the United States 

 and, in the words of the author, it prob- 

 ably will be found wherever tulips are 

 grown. 



Statistics are given to show that the 

 disease is of economic importance. 

 Counts made on the Cornell campus of 

 Darwin tulips showed 100 per cent of 

 the leaves and ninety-eight per cent of 

 the stalks diseased with various de- 

 grees of severity. A report from St. 

 Petersburg, Russia, states that fifty per 

 cent of the tulip crop was destroyed in 

 1911 by this and other diseases. The 

 disease is not confined to the stalks 

 and leaves, but occurs also on the outer 

 parts of the bulbs. It can be detected 

 as small spots or lesions, varying from 

 deep yellow to brown in color, usually 

 circular in outline, and occurring often 

 under the outer, papery skin. It is dif- 

 ficult, however, to determine with cer- 

 tainty the presence or absence of the 

 disease on the bulbs, because small in- 

 fections occur, and, since these are not 

 readily found, but little emphasis can 

 be placed on the selection of clean bulbs 

 as a means of control. On the flower 

 the disease makes its appearance as 

 minute spots, whitish to light brown, 

 the color being bleached from the 

 perianth. Later the spots enlarge, turn 

 to a deeper brown, and the entire seg- 

 ment of the perianth finally becomes 

 dry and wrinkled. The whole flower 

 may become affected and have the ap- 

 pearance of being blighted. 



Unfortunately, control experiments 

 were not carried to completion. How- 

 ever, from the studies made, the author 

 makes the following recommendations: 



Select, so far as is possible, clean 

 bulbs. When the disease appears on 

 the outer skin, this should be removed 

 and burned. 



Avoid injuring bulbs by handling, 

 for infection takes place more readily 

 if the bulb has been bruised or in- 

 jured. 



The bulbs should be stored in a tem- 

 perature of about 40 degrees and 

 the humidity should be low. 



Destroy all diseased plants when they 

 occur in the field or greenhouse by 

 burning. This will limit the spread 

 of the disease. 



The complete description of the dis- 

 ease may be found in memoir No. 45, 

 of the Cornell station. One colored 



FREDERICK W. rUBTCHER. 



BORN in Massachusetts in 1857 aud loft an orphan at the ago of 8 years, 

 Frederick W. Fletcher was soon a pupil of experience. He worked at the 

 printers' trade for twenty-four years, and in 1893 and 1894 was editor of the 

 New England Florist. During this time ho was instrumental in calling attention 

 to the Boston fern and giving it its botanical classification and name. In 1892 

 he built his first greenhouse, at Auburndale, Mass., which soon developed into a 

 good-sized range of glass. Mr. Fletcher introduced a number of plants into thia 

 country, among them the I'rincess of Wales violet. For the last eighteen yearn 

 he has been crossbreeding antirrhinums, freesias, gladioli, etc., with noteworthy 

 results, and he has been honored with many awards of merit by societies at home 

 and abroad. Owing to advancing years, Mr. Fletcher went to Orlando, Fla., five 

 years ago. The illustration above shows him there in hi« field of watsonias. As 

 lie was in Massachusetts, Mr. Fletcher is a live wire in Florida, where he is vice- 

 president of the S. A. F. for that state and a member of the conunittec on orna- 

 mentals of the Florida State Horticultural Association. lie is a charter member 

 of the Florida State Florists' Association.

NAMING A NARCISSUS. 



We are mailing you a specimen of 

 yellow narcissus and we should like to 

 have you tell us the name of the va- 

 rictj'. We have a great many of 

 them mixed among some single jonquil 

 bulbs we bought. They bloom in Feb- 

 ruary at the same time that the jon- 

 quils bloom. The one we are sending 

 you has only two buds on it, but the 

 majority of them have from four to 



This is Narcissus Gampernellii rugu- 

 losus, a fine form of the true, sweet- 

 scented jonquil. I presume the single 

 jonquils you speak of are really single 

 daffodils, often misnamed jonquils in 

 the trade. True jonquils have small, 

 sweet-scented yellow flowers, carried 

 several on a stalk, and with much nar- 

 rower and more grassy-like foliage than 

 have the larger-flowered narcissi.
