AURICULA (Primula auri'cula). The 

 Bear's Ear, or Mountain Cowslip. 



The varieties of this flower are very 

 numerous, and their numbers are annu- 

 ally increased. They are divided into 

 five classes. 1. Green-edged. 2. Grey- 

 edged. 3. White-edged. 4. Selfs, or one- 

 coloured, and 5. Alpines, which have the 

 outer edge of the petals shaded by a mix- 

 ture of two colours, not separated into 

 distinct bands of colour, as in the edged 

 varieties, and the paste round the tube is 

 yellow instead of white, as it is in the 

 edged and selfs. 



" As florists have several terms relative 

 to the Auricula, which may be not under- 

 stood by every amateur, we may as well 

 explain that the thrum is a collective 

 name for the stamens in the very centre 

 or tube of each flower. Paste in the 

 edged and self varieties is the white 

 colour next round the edge of the tube, 

 or eye, of the flower ; it is yellow in 

 the Alpines. Ground colour is the next 

 colour to this on the petal, being the 

 distinctive colour of the variety. Edge 

 is the outer colour of all, forming the 

 border of the flower. A Pip is the single 



flower, and a Truss is several pips, with 

 their several footstalks springing from 

 one stem common to them all. 



" The properties of the Auricula may 

 be divided into two series namely, those 

 of the single pip, and those of the single 

 plant. 



' ' TJie Pip. 1 . Should be circular, large, 

 with petals equal, firm, fleshy, smooth at 

 the edges, without notch or serrature, 

 and perfectly flat. 



"2. The centre, .or tube, should not ex- 

 ceed one-fourth of the diameter of the 

 pip ; it should be of a fine yellow or lemon 

 colour, perfectly round, well filled with 

 the anthers, or thrum, and the edge 

 rising a trifle above the paste, or eye. 



" 3. The paste, or eye, should be per- 

 fectly circular, smooth, and of a dense pure 

 white, without crack or blemish, forming 

 a band not less than half the width of the 

 tube, and encircling it. 



"4. The ground colour should be dense, 

 whole, and form a perfect circle next the 

 eye ; the brighter, darker, or richer the 

 colour, the better the flower ; but if it be 

 paler at the edges (where they are parted 

 into five) or have two colours or shades, 

 it is a fatal defect. 



" 5. The margin or outer edge should 

 be a clear unchangeable green, grey, or 

 white ; and be about the same width as 

 the ground colour, which must in no part 

 go through to the edge. From the edge 

 of the paste to the outer edge of the 

 flower should be as wide as from the 

 centre of the tube to the outer edge of the 

 paste. In other words, the proportions 

 of the flowers may be described by draw- 

 ing four circles round a given point at 

 equal distances ; the first circle forming 

 the tube, the second the white eye, the 

 third the ground colour, and the fourth 

 the outer edge of the flower, and the 

 nearer they approximate to this (except 

 that the ground colour, which may be a 

 little broader than the other bands, and 

 the green or grey edge may run into each 

 other in feathery points) the better the 

 flower. The colours should not be liable 

 to fly, as is the defect of Stretch's Alex- 

 ander, the colours of which fade in three 

 or four days. 



" Of the Plant. 1. The stem should be 

 strong, round, upright, elastic, bearing 

 the truss upright without support, and
