108 NEW AND RARE PLANTS. 



And I now give a brief summary of the very successful result of my 

 owq experience in pot-culture, and which I strongly recommend to 

 others. 



Commence with small plants, having short stout stems and small 

 pots. They require the same rich kind of soil or compost, for pot- 

 culture as they do in the open ground, but more frequent watering 

 (excepting their inactive state in the winter season, when they will 

 need but a very moderate supply) which should be with liquid 

 manure, or foul soap-suds, to be carefully poured into the pot with- 

 out sprinkling any upon the foliage, and shifting into larger pots as 

 the plants advance in size; also frequent top-dressing with leaf- 

 mould, -well rotted dung, or the ashes of burnt weeds, vegetables, or 

 wood. They must be entirely defended from the powerful rays of the 

 sun. They require the natural free air, dews, and rains, until the 

 buds are nearly their full size and begin to expand, at which time the 

 blooms should be defended from wet and winds. At all times they 

 require a free drainage at the bottom of the pot. 



The above is written at the request of a Pansy grower, who being 

 so pleased with the results of my practice, desired me to give him 

 my mode of treatment in pot-culture, as he intends to commence.

LIST OF NEW AND RARE PLANTS. 



ANTIRRHINUM MAJUS FLORA PLENO. DOUBLE BLOOD-COLOURED SNAP-DHAGON. 



There have been double Snap-dragons in our gardens for some years, viz., rose- 

 coloured and white, but this is the first blood-coloured that we have seen ; it 

 was raised by Mr. Young, Nurseryman, of Epsom, in Surrey. All the tribe are 

 well deserving a place in the flower garden, and the one now figured, espe- 

 cially so. 



Barkeria spkctabu.is. Showy Barkeria. OrchideaR. Gynandria Mo- 

 nandria. (Bot. Mag. 4094.) Its native country is Guatemala ; it has recently 

 bloomed in the collection of Mrs. Wray, of Cheltenham. The flowers are pro- 

 duced in long terminal peduncles of eight or ten in each. The flowers are about 

 four inches across. Sepals and petals of a beautiful rosy-lilac. Lip-lilac, 

 spotted with dark chocolate, and having a yellowish centre. Baskets filled with 

 moss, or blocks of wood, are found to be most congenial to the roots of Barkerias ; 

 in peat, they quickly perish. 



Catti.eya intermedia varieqata. Intermediate variegated lipped. (Bot. 

 Mag. 4085.) From Brazil ; the sepals and petals of a lilac-purple, lip white, 

 and a yellowish centre, lamellae red. A very pretty variety. 



Cereus Pitajaya. Variable. (Bot. Mag. 40S4.) In the collection at the 

 Royal Gardens of Kew. It is an erect growing species. The flowers are large 

 somewhat of the size of C. grandiflorus, the night-blooming; white, with : 

 tinge of sulphur.
