ARBORETUM ET FUUTICETUM 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 : 



Tragopy'rum Bieb, Calyx 5-sepaled. Stamens 8. Styles 3. 

 ^trapha'xis L. Calyx 5-sepaled. Stamens 6. Styles bifid. 

 Calli'gonum L. Calyx 5-parted. Stamens 16. Styles 3 4', united at 

 the base.

Derivation. Tragos, a goat, and piiros, wheat. The 3-cornered fruits of such of the Polygon^ccffi 

 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 FagopJ'rum, now the name of a genus that includes the 

 different kinds of buck- wheat 



Gen. Char., Sfc. Calyx inferior, with sepals that are imbricate in estivation, 

 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. i 

 Stamens 8. Styles 3. (G. Don.) \ 



Leaves simple, alternate, stipulate, deciduous or sub-evergreen ; spathu- < 

 late. Floiuers 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. j 



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 pruninj; ; , 

 arc 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. j
