678 ARBORETUM EY FRUTICETUM BRITANNICUM 
Leaves simple, alternate, with cohesive stipules, deciduous or sub- 
evergreen ; when young, rolled backwards. Flowers occasionally unisexual, 
often in racemes.-—Low suffruticose shrubs, natives of the South of Europe 
and Asia, included in three genera, which are thus contradistinguished : — 
Tracory rum Bieb. Calyx 5-sepaled. Stamens 8. Styles 3. 
Arrapua’xis L, Calyx 5-sepaled. Stamens 6. Styles bifid. 
CaLti’conum L. Calyx 5-parted. Stamens 16. Styles 3-—4, united at 
the base.

Derivation. Tragos, a goat, and pz7os, wheat. The 3-cornered fruits of such of the Polygonacer 
as have them are comparable, with some allowance, to wheat ; and goats may feed upon those of 
the Tragopyrum, or upon the shrubs themselves; or it may be that the name has been invented 
as one readily distinctive from the name Fagopyrum, now the name of a genus that includes the 
different kinds of buck- wheat 
Gen. Char., §c. Calyx inferior, with sepals that are imbricate in zstivation, 
permanent; the two exterior smaller, the three interior investing the fruit, 
which is an achenium, that is, 3-cornered in a transverse section of it. 
Stamens 8. Styles 3. (G. Don.) 
Leaves simple, alternate, stipulate, deciduous or sub-evergreen ; spathu- 
late. Flowers in axillary racemes. — Shrubs, small, sub-evergreen, suffru- 
tescent ; natives of the South of Europe, Asia, and America; propagated by 
seeds or layers in dry soil. 
The species are extremely interesting and beautiful little shrubs, and it is 
much to be regretted that they are so very seldom seen in collections. Though 
they require heath soil, and some little time to be firmly established, yet 
when once they are so, from their compact neat habit of growth, very little 
care will be necessary afterwards. They never can require much pruning; 
are quite hardy; and, provided the soil be not allowed to get too dry in the 
heat of summer, they are always certain of flowering freely.
