GARDENING OPERATIONS FOR JANUARY. 



ACOTYLEDONES. 



Polypodium glaucum j sp. nov. fronde ovata glauca profundi pinnatifida; laciniis lanceolatis 

 marginatis obtusis terminali elongata ; soris uniserialibus ; stipite glabro, caudice subsquamoso. 



This species of Polypodium was imported from Mexico amongst some orchidaceous plants 

 by Geo. Barker, Esq. of Springfield. Its nearest alliance is certainly to that of P. areolatum, 

 but from that species it will be seen to be distinct by being glaucous on both sides of the 

 frond instead of only on the one side, by not being farinaceous underneath, and- by having the 

 sori in lines instead of being scattered. From P. aureum it differs in having the divisions of the 

 frond obtuse not acuminate, and the caudex much less chaffy ; it has also a creeping root, and in 

 its native country appears to be scandent. 



CALENDAR OF GARDENING OPERATIONS FOR JANUARY. 



The plant-stove will require the same treatment as recommended for last 

 month. The greenhouse must have plenty of air in mild weather. All leaves must 

 be picked off the plants as they begin to decay, and the plants frequently turned 

 round upon the stage to prevent them from getting one-sided. Fresh surface the 

 soil in the pots when it gets too firm or becomes green. This operation is as 

 necessary to plants in pots as that of digging and hoeing is to those in the open 

 ground. 



The half-hardy plants protected in pits and frames, ought to have abun- 

 dance of air in fine weather, so as to keep their leaves and the surface of the soil 

 in the pots as dry as possible. During severe frost, even if the sun shines bright 

 during the clay, it is more advisable to allow the covering to remain on, par- 

 ticularly after the surface of the pots has begun to freeze. 



A succession of Roses and other hardy plants for forcing ought to be brought 

 into the houses occasionally ; and also Strawberries. 



Kidney Beans, where there is a convenience of forcing them in pine- stoves and 

 early vineries, may now be sown in pots with a tolerable certainty of obtaining a 

 good crop. The forcing of Cucumbers is frequently commenced in November with 

 uncertain success, but ought now to be commenced whether it has been attempted 

 earlier or not. Cuttings of the more free-growing Ericas, such as hybrida tubijlora, 

 gracilis, caffra, persoluta, Sfc, should now be put under bell-glasses ; these will be 

 rooted, and thus allow the glasses to be ready for -the more difficult kinds in 

 March. 



This is the very best month for inarching Camellias. Cuttings of Verbenas, 

 Salvias, Fuchsias, and other soft-wooded plants, may be struck in heat so as to 

 be ready for turning out into the flower borders in May. 



Roots of the very newest Dahlias may now be potted and set a-growing to 

 obtain top cuttings : but it is a bad practice to begin starting them so early 

 unless when considerable increase is wanted. Plants from top cuttings seldom 

 do so well for growing as those taken off with a heel later in the season ; and 

 many of the roots frequently perish during the ensuing winter for want of a 

 sufficient number of eyes near the root.
