THE FLOEAL WORLD AND GARDEN GUIDE. 119 



of paint, when the pipes are not excessively hot, which is hardly likely to he the 

 case at this time of the year. To enhance the efficacy of the sulphur, keep the 

 house shut up as long as you can before giving air for a couple of mornings after 

 the trees are dressed, by this means the fumes will rise very strong and have double 

 effect; perhaps, by way of caution, we had better observe that the air-giving 

 must not be deferred until the foliage is injured. We have never found any 

 difficulty in dispersing mildew with the aid of good sulphnr. These remarks will 

 apply to the case of XF.Z., l*oma, W.H.T.M., and others whose trees are covered 

 with mildew ; and unless the sulphur is applied promptly, the crops will be ruined 

 for this year. The fruit will become hidebound, and split in all directions when it 

 begins to swell out after stoning, and consequently be rendered unfit for table or 

 anything else. 



Gkeexhouse Lycopodiums or Selaginellas. — A Lady Amateur. — The fol- 

 lowing selection will do admirably for growing in your conservatory. People very 

 often fail in growing these beautiful and easily-managed- plants, through exposing 

 them to the same amount of air and light as the hard-wooded plants. The delicate 

 foliage will not stand rough treatment with impunity, for it soon assumes a brown 

 rusty colour, to prove to t'.ie cultivator that the plant is not receiving the right 

 kind of treatment. These plants are propagated by cuttings and division, and 

 thrive best in pans about six inches deep, well drained and filled with a mixture of 

 fibry peat, loam, and leaf-mould in equal proportions, with plenty of sand. There 

 are many more splendid kinds, but these are the most suitable for the conservatory. 

 Selaginella apoda, a pretty little dense-growing kind, requires care in watering, 

 otherwise it will go mouldy in the centre. S. denticulata, the old common kind, 

 but very beautiful and free growing, one of the most useful we have. S.formosum^ 

 a fine kind, the habit close and massive-looking, very easy to propagate, and grows 

 about a foot high. S. 3Iartensii, 'a fine erect close habit, same height as the pre- 

 ceding. S. cuspldata, a very beautiful growing kind, foliage forms quite a bird's 

 nest ; and S. W^ildenovii, a fine spreading kind. 



Primulas after Flowering. — E.A.H. — It is a most difficult matter to preserva 

 single primulas through the summer, for even if they are kept alive, it is a hundred 

 chances to one that they go ofi" in the winter when they are in flower. When extra 

 large plants are required, for blooming early in autumn, it is a capital plan to sow 

 the seed late in the summer, and keep the plants in rather small pots through the 

 first winter and following spring ; and then "if they are potted on through the 

 summer, and grown in a cool and rather shady position, they make grand plants for 

 November, December, and January. As you have flowered your plants in the 

 ordinary way, the best course for you now to pursue will be to toss them away at 

 once, and get up a fresh stock from seed, as you have hitherto done. Keeping the 

 old plants will give you a deal of trouble, and then probably the whole affair will 

 end in disappointment. 



The Names of Plants, ax old difficitltt.— I have done a good deal 

 towards recommending the Floral World to my friends, but I am often told it is 

 too learned for ladies. They are not well up in the botanical names of plants, and 

 are often disappointed when they order some, what they think, new seeds, and find 

 they are what they have had ^in their gardens for years. Could you not give the 

 common name with the botanical ? I only suggest this change as a means to 

 increase the circulation of such a useful liitltt book. I read the Floral World each 

 month, as it is sent to my husband for review. Wishing you evei'y success. — J. O'D. 

 [If we were to say that we have had hundrcils of letters on this subject, the 

 writers having in view the same object as J. O^D., we should scarcely exaggerate 

 the fact. Usually the complainants are ladies, and always, we trust, our replies 

 have been polite, though they may have appeared otherwise, as we fear will be the 

 case now. In the first place, then, we have to say that the complaint has no foun- 

 dation in fact. Now, for example, take any number of the Floral World, and every 

 plant referred to or described has both its Engli'h and its Latin name, if it can boast 

 of both ; but if it never had an English name, it follows that the Latin must be 

 sufficient. More than this, we have adopted freely names not generally recognized, 

 and have sometimes invented names expressly for the benefit of those lovers of 

 plants who think they must suffer dislocation of their maxillaries {AngVico^ jaw-bones) 

 if they " allium call their onions and their leeks." For example, when speaking of 

 Tritoma uvaria, a name which we suppose easy enough to pronounce and re-
