THE FLORAL WORLD AND GARDEN GUIDE. 



29. Pinnatifidum. — Similarinform 

 and habit to 28, and adapted for the 

 same purposes. 



30. Brachypteron. — The fronds 

 pendant, nearly twice-divided, bright 

 green, bearing young plants at their 

 points, very elegant, and being of 

 minute growth must be treated as 

 recommended for 28. 



31. Dimidiatum. — A small palm- 

 like fern of exquisite beauty, as well 

 adapted for case culture as any 

 fern known. The stipes stout, rising 

 from a scaly crown, the fronds two 

 inches wide, once-divided, their 

 pinna? unequally four-sided and 

 toothed towards the points. A scarce 

 and expensive kind. 



32. Meclinatum. — A lovely small 

 fern, producing once-divided pendant, 

 greyish-green fronds, at the points of 

 which are borne viviparous plants. 

 A charming fern for suspension. 



These and the Aspleniums enu- 

 merated at p. 193 of lastyear's volume 

 are all of this genus that I shall bring 

 forward in this series. I have grown 

 many others in cases, so many in fact, 

 that if I enumerate all, these papers 

 will become wearisome to the readers 



of the Plobal World. I therefore 

 content myself with naming such as 

 are likely to suit cultivators who do 

 not indulge in extensive collections, 

 yet wish to know something about 

 the most useful and interesting ferns 

 for case and greenhouse culture. As 

 there are so many beautiful species 

 that are nearly hardy, and for which, 

 therefore, the aid of artificial heat is 

 not required, it will be found advan- 

 tageous to group them as to their 

 climatal requirements, so that one 

 system of management will suit all 

 the species planted in a case. A 

 botanical system of grouping may be 

 combined with this, and for a group 

 of Aspleniums there could scarcely be 

 a better selection than the kinds 

 enumerated above. But the Adian- 

 tums have equally high claims to be 

 grouped together, and a pair of 

 large cases would be well appro- 

 priated to these two families, the 

 Aspleniums being left to fight it out 

 all winter without the aid of heat, 

 the Adiantums to be assisted with 

 heat from the beginning of November 

 till the 1st of May.

A LESSON" IN VINE PRUNING. 



Having before us several queries on 

 the pruning of grape vines, it seems 

 desirable to treat the subject in a 

 more general manner than can be 

 done in the ordinary form of replies 

 to correspondents. Having offered 

 the inexperienced among our readers 

 a few plain instructions on pruning, 

 we may be enabled hereafter to treat 

 on other points in the practical culti- 

 vation of the grape vine, and so, in 

 the course of time, provide our readers 

 with a code of rules of some such 

 kind as has been done already for 

 other important subjects. The pre- 

 sent lesson is to be on pruning only, 

 and it is to be as short as possible, 

 consistent with the accurate and ex- 

 plicit description of particulars. 



General Dieections. — Prune as 

 soon as possible after the leaves are 

 down, and there will be no bleed- 



ing. Leave the pruning till the vines 

 are about to grow, and they will 

 bleed profusely. When you cut away 

 a portion of a shoot always cut close 

 above a bud, and so as to leave the 

 pruned part of the shoot at an angle 

 of 45° with the bud at the extremity, 

 thus— (Fig. 1) 



Pettning Young Vines. — Young 

 vines should never be allowed to bear 

 fruit until they have formed stout 

 hard wood. If the pruner is timid at 

 his work, and does not cut back the
