[ April, 
contain the seeds or pips. They are usually five, but vary in number, and differ 
very much in structure, being either open to the axis of the fruit, or closed. 
Some sorts have the seed-cells perfectly closed (fig. 2 a), some have them open 
(fig. 2 5), and in others again they are wide open (fig. 2 c). The seed-cells mark 
the second series of divisions, thus :— Cells open or Cells closed. 
The Calyx-tube is the cavity, more or less deep, lying between the segments of 
the eye and the seed-cells, and which is seen on making a vertical section through 
the exact centre of the fruit. It is the Kelcli-rohre of the Germans, and is of 
varied form, but all are modifications of three distinct t 3 "pes, called the conical, 
the funnel-shaped, and the cup-shaped. In some cases the tube is wide and 
deep (figs. 3 c, 3 d, 4 5, 4 c), and in others narrow and short (figs. 3 n, 3 J, 
3 c, 3 /, 4 cf, 4 cf, 4 e). The third set of sub-divisions is based on variations in the 
form of this cavity, the distinctions being:— Calyx-tube conical. Calyx-tube 
funnel-shaped, or Calyx-tube cup-shaped —the latter very seldom met with. 
The remains of the Stamens are the bristle-like bodies which form a fringe 
round the inner surface of the Calyx-tube. In some this fringe is placed imme¬ 
diately under or near the base of the segments, these being called marginal (figs. 
3 J, 3 t?, 4 5, 4 e) ; in others it occupies a midway position between the margin 
and the base, and these are all called median (figs. 3 c, 3 /, 4 a) ; while in a 
third, it is situated near the base, and these are called basal (figs. 3 n, 3 c, 4 d). 
The fourth sub-division, therefore, taken from the position of the stamens, is this:— 
Stamens marginal. Stamens median, or Stamens basal. Beyond this point, 
the groups may be subdivided into those with the Calyx-tube short conical, 
or deep conical. Calyx-tube short funnel-shaped, or deep funnel-shaped, and we 
think, looking at the illustrative figures, that short and deep cup-shaped might 
have been added. The form and colour of the fruit serve to mark further sub- 
divisions. > 
' The chief difficulty in working out this or any other arrangement lies in 
what the author calls “ the changeableness of the characters in some varieties ” ; 
for some exhibit the eye or cells open or closed, or intermediate between the two, 
in different examples; while the form of the calyx-tube, and the positions of 
the stamens are not absolutely constant. Hence, in the list of some 300 varieties 
given in illustration, we find that the Winter Greening drops into six distinct 
places, the Cornish Gilliflower into four, and the Calville Blanche and numerous 
others into three. The system, therefore, is at present suggestive rather than com¬ 
plete, wanting further elaboration, which, it is to be hoped, may clear away the 
objections and shortcomings which are now apparent.—T. Moore.
