ANALYTICAL DRAWINGS OF THE SPURGE, BOX, 
WATER STAR WORT, HOLLY, SPINDLE-TREE, MAPLE, BUCKTHORN, 
AND LINDEN FAMILIES— continued. 
figures well exhibiting the tetramerous symmetry of the flower. Fig. 4 is a 
longitudinal section through a perfect flower, enlarged ; and Fig. 5, a transverse 
section, natural size, of a berry, which only shows three stones or endocarps, 
although four are usually present. 
The Spindle-tree (Euonymus europ<eus Linn6) again is the sole British repre- 
sentative of its Family, the Celastrace which is even more uniformly tetramerous. 
Fig. 1 in the sixth line is a flower seen from above ; and Fig. 2, the same from 
below, both natural size. Fig. 3 is an enlarged view of the floral receptacle and 
essential organs from above ; Fig. 4, a side view, natural size, of a flower with 
its corolla removed ; Fig. 6, an unripe fruit ; Fig. 5, a longitudinal, and Fig. 7, 
a transverse, section through the same ; and Fig. 8, a longitudinal section through 
the rose-coloured pericarp of a ripe fruit, showing the scarlet arils covering two 
of the four seeds. 
The seventh line represents the Hedge Maple [Acer campestre Linne), Fig. 1 
being a flower seen from below ; Fig. 2, the receptacle and stamens of a male 
flower ; Fig. 3, a stamen, and Fig. 4, the same enlarged ; Fig. 5, a carpellate 
flower ; and Fig. 6, the young fruit. 
The penultimate line of figures represents the Alder Buckthorn ( Rhamnus 
Frangula Linn6), Fig. 1 being a flower, natural size, seen from above ; Fig. 2, 
the same in side view ; and Fig. 3, a magnified longitudinal section, showing 
the pentamerous calyx which is greener than it here appears, the greenish -white 
petals, perigynous stamens, and superior ovary. Fig. 4 shows a trilobed unripe 
fruit ; Figs. 5 and 6 show the three stones ; and Fig. 7, one of them in section, 
exhibiting the one seed it contains. 
The last line of figures represents the flower of a Linden ( Tilia ), Fig. 1 
being a flower, natural size ; Fig. 2, the same in longitudinal section, magnified ; 
Fig. 3, the gynaeceum, showing the pubescent ovary ; Fig. 4, one of the 
remarkable stamens with divided anther-lobes ; Fig. 5, an unripe fruit ; Fig. 6, 
the same in transverse section ; and Fig. 7, the same, at a later stage, slightly 
enlarged, showing the five chambers which ultimately become one, with two 
ovules in each of the original chambers, attached to a central placenta.
