or coloured calyx-leaves spreading. Native of N. America. 

 Flowers in Alay, June, and July. 



T. asiaticus {Siberian G/obe- Flower). — This species grows 

 about a foot high, with leaves similar to those of the last, which 

 are characteristic of all the Globe-Flowers ; and the sepals, about 

 ten in number, are dark orange and spreading. Flowers in 

 May, June, and July. Native of Siberia. 



T. caucasicus ( Caucasian Globe-Floiver). — This species grows 

 about t8 inches high, with large bright-yellow flowers, the sepals 

 in which assume a more globular form than in the two preced- 

 ing species. Flowers in May and June. Native of the Cau- 

 casus. 



T. europseus {Eiwopean Globe-Flower). — A handsome species, 

 growing about 2 feet high, with large lemon-coloured very glo- 

 bular flowers. Native of central and southern Europe, and 

 found also sparingly in Britain. Flowers in May, June, and July. 



T. napellifolius \Napellus-leaved Globe-Flower). — This species 

 is nearly allied to the last, but easily distinguished from it by 

 the deep yellow and less compactly globular flowers. Flowers 

 in May, June, and July. Native of Europe.

This natural order of plants comprises only a very limited 

 number of herbaceous genera, and none of these may be con- 

 sidered plants of showy character ; for, unlike the majority of 

 the shrubby species, they are more remarkable for their curious 

 structure than for striking beauty. The most important herba- 

 ceous genus is Epimedium, for the purposes of ornamentation : 

 in it there is a very happy union of grace in habit and foliage 

 and beauty, as well as high interest in the flowers. Jeflersonia 

 is perhaps the only other genus that may be admitted into col- 

 lections other than botanical, and it should be in every collec- 

 tion of choice beautiful plants, being at once both curious and 

 handsome. The culture of these two genera must be the same. 

 They succeed best in sandy loam and peat of considerable 

 depth, and all the better if moist, though perfect freedom from 

 stagnation must be secured, and they prefer a little shade ; but 

 that is of less consequence than a properly-constituted soil. In 

 the mixed border they form elegant objects for the front lines, 

 and they are very fit also for rockwork, especially where the 

 natural soil is unfit for them-— that is, heavy loam or clay.
