Cyclamen Failing. 



-R. W. D., Croydon: We could find no insects on 

 ^SS^^W.'biit there has evidently been something at work eating 

 t rt* The grub of some curculio may have been the cause, and might have 

 tlnim ported with the leaf-soil. As the plants are small it would be a good plan 

 t carefully wash the soil from them, cleaning the corms as well as possible, and 

 hen repotting in new soil of a light character and using small pots, 

 used first place it in an oven and subject it to heat sufficient to kill all insect 

 e Maintain a genial warmth in the house or pit, keep up a fairly moist atmos 

 'here but give little water to the plants otherwise until they have rooted freely 

 and are making satisfactory growth.

Twin-flowered Cypripediums. 



A. B., Epsom : We are obliged to you 

 The form of Cypripedium insigne you 



for your reference and the blooms sent. 



have is a first-rate example of the old type ; this is, it does not belong to the so- 

 called 1 1 montanum ' 5 group. Twin-flowered scapes are no doubt due to excep- 

 tional vigour in the plants, so that it is very evident your specimens are growing 

 under conditions they fully appreciate. It is seldom, if ever, the case, that a 

 growth giving a twin-flowered scape one year repeats itself the next ; the vigour 

 seems to find vent in producing two blooms, and in a succeeding year the plant 

 flowers in the usual way. We have not seen C. Spicerianum produce a twin- 

 flowered scape ; your mode of cultivation evidently suits the species. We recently 

 saw three twin-flowered scapes on a specimen of C. Harrisianum. 



Marechal Kiel Rose — R, Surrey: Cut the roses back pretty hard at 

 planting time, so that some strong shoots will be produced from the base and 

 enable you to soon furnish the wall. If there is need of a rod of some length, as 

 in the case of training a rose to the roof, then only prune it back to the point from 

 whence it is desirable to obtain several growths. When the plants are turned out 

 of the pots remove the crocks with the aid of a pointed stick, and also remove 

 any loose surface soil there may be ; any roots that can leadily be laid or spread out 

 should so be treated, but the work must be accomplished most carefully or much 

 damage will be done. If the roots are not entwined or twisted round and round 

 just inside the pot, then they may be spread out, but otherwise an attempt to 

 spread them will end in breakage and disaster. If the plants are what is known 

 as pot-bound, then loosen the roots slightly, removing crocks and loose soil, then 

 at planting see that the new soil is pressed firmly against the ball so that new 

 roots will be encouraged to penetrate it. 



Violets and Pansies.— E. P., Norwich : Thanks for letter. You should 

 keep the violets as cool as possible, fcr under ordinary circumstances they should 

 flower at the period you wish them to appear. Those in the open ground should 

 be protected during severe weather, such as frost, snow, and driving east winds, 

 by means of a handlight or similar appliance. Give plenty of air on all favourable 

 occasions to those in frames, and do not put them into the greenhouse until about 

 three weeks before you want them. Practically, the same remarks applies to violas, 

 though these will need rather more care to have them nicely in flower for the 

 occasion. Those in pots in frames should have the flower buds picked out, should 

 they appear, until the end of February ; give them the warmest and lightest posi- 

 tion possible, water carefully, remove all decayed foliage as soon as detected, and 

 take advantage of bright, warm days to give plenty of air. The warmth of a 

 greenhouse should only be afforded two or three weeks before the date given, pro- 

 vided a little stimulation is at that date desirable. We have not the address you 

 need, but will endeavour to obtain it for you. 



Names of Plants. 



— Under this heading we can only undertake to name 



species and specific varieties of plants, and not florists' flowers. Specimens should 

 be packed in stout boxes with damp moss or leaves as packing material to ensure 

 their reaching us in a fresh state. It is essential that flowers must accompany 

 specimens of flowering plants, that fern fronds be fertile, and that the numbers be 

 legible and firmly attached to the specimens. We cannot promise to name more 

 than six specimens at one time from any one correspondent. 



L. B., Liverpool: I, Selaginella caesia ; 2, S. Kraussiana ; 3, S. Mertensi. 

 B. P. G., Merton : 1, Cupressus Lawsonianus ; 2, Eleagnus longipes; 3, 

 Osmanthus illicifolius ; 4, Hamamelis arborea ; 5, Jasminum nudiflorum.

The mean reading of the Barometer during the week at Greenwich was 30*26 inches, and that 

 of the Thermometer 45°'i, the latter being 6°'7 above the week's average in the 50 years 

 1841 — 90. The direction of the wind was south-westerly, the horizontal movement of the air being 

 13 per cent, below the week's average in the 16 years 1860—75. The duration of registered bright 

 sunshine in the week was V4 hours. The measured rainfall amounted to 0*12 of an inch.
