vorhanden....Aufgefunden wurde diese hiibsche Form vor etwa zehn 

 Jahren von Baumschulbesitzer Finck aus Doberan, der sie seitdem 

 unabliissig vermehrte und jetzt einen grossen Posten stattlicher Pflanzen 

 besitzt, die die Firma J. C. Schmidt-Erfurt erworben hat.... Die durch 

 Spoitbildimg erzeugte goldgelbe Farbe ist soiuit durch gauz andere 

 Faktoren bedingt als die der Herbstfarbung uud liat gewiss auch mit 

 der durch Nahrstoffmangel hervorgerufenen Chlorose nichts zu schaffen, 

 da auch iippiges Wachstum die Pflanzen nicht so leicht in die griine 

 Stammform zuriickfiihrt." The coloured plate accompanying the above 

 description is entitled " Hmnulus Lupulus aureus (Goldenes Vliess)"; it 

 shows no flowers. The plant is referred to again in Die Gartenwelt, x, 

 p. 498 (1906), where the name "Goldhopfen" is proposed for it. 



It seems clear from the information (given above) supplied by 

 Messrs Dicksons that the plant distributed by them is the true H. Lupulus 

 aureus. It is possible that the susceptible male golden hop which has 

 become mixed up with the immune female golden hop in the stocks held 

 by Messrs Bunyard and by Messrs Bide and Son is also the var. aureus, 

 but I have not had the opportunity yet of comparing mature plants. 



(3) A third form with "golden" leaves was brought to my notice 

 by Mr Jesse Amos, Foreman Recorder at the Wye College Fruit Experi- 

 ment Station at East Mailing. This plant, which is growing in a garden 

 at Mailing, was obtained originally from Messrs J. Veitch and Sons, 

 of Chelsea. I have not been able to obtain any information as to its 

 origin. It is of the female sex; three cuttings taken from it in 1918-19 

 proved in the greenhouse during 1919 to be slightly susceptible to 

 mildew. It is therefore different in constitution at any rate to the plant 

 sent out by Messrs Bunyard and Messrs Bide and Son. I have not yet 

 had the opportunity of studying mature plants of this susceptible 

 female golden hop. 



To summarise the facts : we have in cultivation in nurseries and gardens 

 in this country three forms of the Golden Hop, viz. (1) an immune female 

 Golden Hop; (2) a susceptible female Golden Hop; (3) a susceptible 

 male Golden Hop, the true H. Lupulus aureus^. 



As previously reported in 1919(2) the female "Golden Hop" from 

 Messrs Bunyard and from Messrs Bide and Son has proved completely 



1 In The Hop Farmer by E. J. Lance (1838), p. 157, the following appears: " Varieties 

 of Hop. — There is another raised by Mr W. Paine at Farnham, having the appearance of 

 the autumnal tint of the leaves, they are always ' in the yellow leaf ' ; indeed their appearance, 

 compared with the red bine, or black knots, is very striking, the one being a dark blue, 

 while the other is a light yellow green; this variety of hop branches out very much and 

 yields a deUcate coloured strobile." This "golden" variety does not appear to have been 

 cultivated commercially.
