shrub, forming a close compact bush, with thick coriaceous leaves 

 covered with silvery tomentum beneath, as well as the stem and 

 petioles. The large flowers are bright purple. It grows best planted 

 in full sun, and does not mind exposure to wind as do many other 

 species of the same class. — G. R. 



Roses, Three New (Rev. Hort. Beige, No. 4, p. 61, Feb. 15, 1912 ; 

 plates). — Three new Roses produced by Messrs. Soupert and Notting are 

 said to be valuable acquisitions. 



' Comtesse Felicie Hoyos ' (cross between ' Ant. Onivire ' and ' Mme. 

 Mel. Soupert ') is light salmon-yellow in colour, shaded coppery pink 

 centre. 



' Maman Lyly ' (cross between ' Mme. Mel. Soupert ' and ' Mrs. Peter 

 Blair ') has a perfectly-shaped flower resembling a ' Souv. de la 

 Malmaison.' Tender flesh-pink in colour. Surpasses all others of 

 that shade. 



* Tito Hekeyan ' (cross between ' Mme. Mel. Soupert ' and ' Lady 

 Ashtown '). Very large flower, colour coppery coral pink, shaded with 

 yellow ; centre bright purply coral. A new type of hybrid tea. Very 

 floriferous. Inestimable for all uses. — M . L. H. 



Seeds, After-ripening of. By Sophia Eckerson (Bot. Gaz., pp. 286- 

 299 ; April 1913). — The author finds that the delayed germination 

 of Pinus sylvestris, P. Strobus, and P. Cembra is not due to coat charac- 

 ters. No shortening in the time necessary is produced by removing 

 the seed-coats. Seeds of Fraxinus excelsior sown in spring do not 

 germinate till the following spring. The ether treatment hastens 

 growth at the beginning and near the end of the resting period, but 

 not in the middle period. Shoots immersed in water at 35 0 C. produced 

 buds earlier than those untreated. The warm-bath treatment increases 

 respiration and some have hastened germination of potato tubers 

 and Lily of the Valley by this means. There is, however, no lasting 

 effect unless the bulbs are kept at a high temperature. Both zero 

 temperature and injury increase the sugar content. 



Development of buds may be hastened by injury (in which case 

 the shoots are, or may be, abnormal), by immersion in dilute solutions 

 of alcohol or sulphuric acid, and by standing the cut ends of shoots 

 in Knop's solution, also by radium emanations. 



Removal of seed-coats assists germination of Crataegus seed, but 

 only 2-5 per cent, germinate. With C. mollis, intact seeds require 

 a year to germinate, but germination is delayed even with all coats 

 removed. 



The author finds a very gradual though constant increase in the 

 acidity and in the enzymes during the whole after-ripening period. 

 After eighty to ninety days at 5 0 C, when acidity has almost reached 

 its maximum, the fats begin to break up and sugar appears with 

 oxidase. Hydrocyanic acid appears after seventy-five days and 

 increases up to germination, then decreases.
