delightful odour of its flowers, and valuable for the 

 period of its flowering, being from December to March, 

 according to the situation; leaves scattered, oblong, 

 lanceolate, smooth; flowers small, white, in many- 

 flowered terminale heads. D. hybrida is a species in 

 high estimation at present in Europe, but little known

 fine species, and in Europe are esteemed ornaments 

 in the shrubbery, but we are not certain if they will 

 prove hardy in our vicinity.

 Having previously observed a few of the other species 

 and varieties, we will observe the treatment of these. 

 P. sinensis, now prcenitens, known commonly as China 

 Primrose; flowers pink, and in large proliferous um- 

 bels, flowering almost through the whole year, but 

 most profusely from January to May. Keep them in 

 the shade, and be careful that they are not over-water- 

 ed during summer. As the stems of the plant become 

 naked, at this repotting a few inches should be taken 

 off the bottom of the ball, and placing them in a larger
