CLXIV.— ANALYTICAL DRAWINGS OF 
THE SPURGE, BOX, WATER STARWORT, HOLLY, 
SPINDLE-TREE, MAPLE, BUCKTHORN, AND 
LINDEN FAMILIES. 
( JLuphorbiacece , Buxacea, Call it rich a cea, Aquifoliacece , Celastracece , 
Aceracece, Rhamnacea, and Tiliacece.) 
T HE nine plants of which analyses are given on this Plate belong to eight 
different Families, the first two lines of figures illustrating the Spurge Family 
( Euphorbiaceef ). 
The former of these represents the Wood Spurge ( Euphorbia amygdaloides 
Linne), Fig. i being a cyathium seen laterally, with one staminate, and the long- 
stalked female flower ; Fig. 2, the same seen from above and enlarged, showing 
the four crescentic glands ; Fig. 3, the fruit, seen from above, about natural size, 
when fully developed ; Fig. 4, the withered cyathium and enlarging female flower ; 
Fig. 5, the ovary (female flower), further developed ; and Fig. 6, the same in section. 
The second line represents the Dog’s Mercury ( Mercurialis perennis Linne), 
Fig. 1 showing the staminate or male flower from above, enlarged, with three sepals 
having incurved points and a number of stamens ; Fig. 2, a female flower, from 
another plant, the species being usually dioecious ; Fig. 3, the male flower, natural 
size ; Fig. 4, the style and axis from which the two carpels separate in the female 
flower ; Fig. 5, a fruit, natural size ; Fig. 6, the same, showing its partial dehiscence ; 
Fig. 7, a longitudinal, and Fig. 8, a transverse, section through the same. 
In the third line of figures we have the details of our one species in the 
Buxacea , the Box ( Buxus sempervirens Linn£), Fig. 1 being a staminate flower, seen 
from above ; Fig. 2, a stamen ; Fig. 3, the perianth, or calyx, and some stamens 
seen from the side ; Fig. 4, the same, enlarged ; Fig. 5, a carpellate flower ; and 
Fig. 6, a transverse section of the three-chambered, six-seeded ovary. 
The fourth line represents the structure of the Water Starwort ( Callitriche 
palustris Linne), a much reduced type of flower. Fig. 1 is a staminate flower, 
consisting of a single stamen with two colourless bracteoles, and the reflexed foliage- 
leaves ; Fig. 2, a female flower, shortly stalked, of two united carpels with long, 
erect, stigmatiferous styles ; Fig. 3, .the unripe four-winged fruit, enlarged ; 
Fig. 4, a ripe fruit, partly seen in transverse section ; and Fig. 5, a longitudinal 
section. The two carpels are so inrolled as to form a four-chambered ovary with 
a seed in each chamber, and the distinctions between the species depend largely 
upon the keels or wings to the fruit. 
The fifth line gives the details of the Holly (Ilex Aquifolium Linne), another 
solitary British representative of its Family. Here Fig. 1 shows a staminate flower 
from above, natural size ; Fig. 2, the same from below ; and Fig. 3, the calyx, these
