Greenhouse bulbs. Offset bulbs; old bulbs 

 are generally obtained from Italy every year, 

 and are planted in rich sandy loam ; and when 

 growth has fairly commenced, they get the 

 advantage of a slight hotbed to forward them 

 (but the bulb and not the top should be kept 

 warm), before getting them ready for rooms or 

 greenhouses.

POLYANTHUS. This is a variety, but 

 a very permanent one, of the common 

 Primrose (Pri'mula vutya'ris). There 

 are many varieties, and their excellence j 

 as florists' flowers may be determined j 

 by the following rules : 



Tiie Pip. 1. This should be perfectly 

 flat and round, slightly scolloped on the 

 edge, and three-quarters of an inch in | 

 diameter. 



2. It should be divided in (five or) 

 six places, apparently forming (five or) 

 six flower-leaves, each indented in the 

 centre to make it a kind of heart-shaped 

 end ; but the indentations must not 

 reach the yellow eye. 



3. The indenture in the centre of the 

 apparent flower-leaves should be exactly 

 the same depth as the indenture formed 

 by the join of these flower-leaves, so 

 that it should not be known, by the 

 form of the flower, which is the actual 

 division and which is the indenture ; in 

 other words, which is the side and 

 which the centre of the flower-leaf ; and 

 all the indentures should be as slight 

 as possible to preserve the character. 



4. The flower should be divided thus : 

 the yellow tube in the centre being 

 measured, the yellow eye, round the 

 tube, should be the same width as its 

 diameter ; and the (/round colour of the 

 flower should be the same width : or 

 draw with the compasses, opened to 

 a sixteenth-of-an inch apart, a circle for 

 the tube or centre ; open them to three- 

 sixteenths, and draw another circle for 

 the eye, then open them further to five- 

 sixteenths, and draw a third circle for 

 the ground or dark colour. Beyond 

 these circles there is a yellow laciny, 

 which should reach round every flower- 

 leaf to the yellow eye, and down the 

 centre of every petal to the eye, and so 

 much like the edging that the flower 

 should appear to have (ten or) twelve 

 similar petals. The ends of these 

 (ten or) twelve should be blunted, and 

 rounded like so many semicircles, so 

 that the outline of the circle should be 

 interrupted as little as possible. 



5. The tube (one-fifth the width of 

 the whole flower) should be nearly 

 filled up with the six anthers, which 

 are technically called the thrum (have 

 an elevated edge rendering it trumpet- 

 eyed), and the flower should not exhibit 

 the pistil. 



0. The edginy round and down the 

 centre of the petals formed by tbe 

 divisions, should be of even width all 

 the way, and uniformly of the same 

 shade of sulphur, lemon, or yellow us 

 the eye, and there must not be two 

 shades of yellow in the eye. 



7. The ground colour may be just
