M. Otto disapproves entirely of the practice of taking up 

 the bulbs, and drying the roots, as they not only become 

 weaker, but are more liable to rot; neither will they flower 

 sooner, as some believe. Amaryllises cultivated in this 

 way will sometimes flower twice in a year, and the bulbs 

 are always found to be very healthy and strong. 



14. Opinion of the Coynmittee on different Papers. 

 M. Bouche, nurseryman at Berlin, gave an account of a 

 i?osa turbinata, in his garden, which produces four thou- 

 sand blossoms : it was trained on an espalier frame, of which 

 it covered 112 sq.ft.; and he recommends this species par- 

 ticularly for making rose water, on account of its strong 

 scent. [This is one of the most vigorous-growing kinds of 

 rose which British collections yet contain, and is fit for 

 coarse shrubberies. It bears a profusion of flowers, but 

 these are usually one-sided and misshapen. Many possess 

 7?6sa turbinata, perhaps, unconsciously : it is remarkable for 

 its large turbinate (that is, top-shaped) calyx, and the English 

 name for it is the Frankfort Rose. — J. D.~\ 



16. A Method oj" protecting the tender Kinds of Rhododendrons^ 

 Roses, and other Shrubs, in the open Ground, from xiery severe 

 Frosts. By M. Bosse, at Oldenburg. 



Stakes are fixed round the plants, and willow rods loosely 

 woven among them ; on the outside of this basketwork 

 another must be made, at about 8 or 10 in. distance, and 

 the space between the two circles filled up with leaves 

 or moss. A cover is made like a straw roof; and, by being 

 larger than the external basket, serves to keep the wet from 

 it. The bottom, in the inside, must be covered with leaves. 

 In fine weather air may easily be given, by taking off" the 

 straw cover, and the plants will remain green and healthy. 

 Tender climbing plants may be protected, by fixing them 

 round the inside of the basket. 



17. On Ainar^llis gigaiitea, and its Cidture. By M. Schneevogt, 



at Haerlem. 



This plant flowered first in the year 1805, in Holland, 

 where it had existed for sixteen years without being known, 

 in consequence of its not flowering. M. Rosenkranz was 

 the sole proprietor of this Amaryllis ; from which only a 

 few were propagated, till, in the autumn of 1820, several 

 English nurserymen armounced it for sale, but at a very high 

 price. After this M. Schneevogt i-eceived some of these 

 bulbs from the Cape, in a season when it was too late to 

 plant them in what is called in Holland a Cape frame ; he
