an admixture of cocoa-nut fibre refuse, say one part of fibre to two parts 
of the garden soil, to which has also been added a little sand. 
Description Of The central group is a plant of C. palustris jiore 
Plate 7. pleno ; and of the subordinate figures—1 is a section 
through the flower showing the arrangement of stamens and carpels; 2 
shows the carpels alone. In Fig. 3 these carpels have developed into 
ripe seed vessels—open follicles containing two rows of seeds. 
GLOBE FLOWERS 
Natural Order Rantjnculaceje. Genus Trollius 
Trollius (Old German, trol , a globe). A small genus consisting of 
nine species distributed over the north temperate and Arctic regions. 
They are erect perennials with palmately lobed leaves, and large terminal 
globular flowers, yellow or lilac. Sepals, petal-like, five to fifteen; petals 
small, narrow, five to fifteen. Stamens numerous. Carpels, five or more, 
ultimately becoming follicles. 
Principal Species Trollius europasus (Europe), the Globe-flower, is a 
native of Britain; £ to 2 feet high, with leafy stems and 
pale yellow globose flowers; June to August. 
T. asiaticus (Asia), a Siberian species, 1 to 1| foot, is similar to 
europceus, but the larger, dark orange flowers are solitary; May and 
June. Petals longer than stamens. 
T. caucasicus (Caucasus). Yellow flowers; stamens longer than 
petals, otherwise similar to asiaticus. 
Cultivation a natural state Trollius likes a rather heavy moist 
soil, but under cultivation it will thrive in any fairly good 
garden soil. It is a suitable subject for the mixed border. Propagation 
is effected by root-division in autumn; and by seed, which takes a year 
to germinate. 
FENNEL FLOWERS 
Natural Order Ranunculace^:. Genus Nigdla 
Nigella (from Latin, niger, black: the colour of seeds). Fennel¬ 
flowers. A small genus of erect annuals with alternate compound leaves, 
the divisions cut into thread-like segments, perhaps suggesting the 
popular name. The flowers are white, yellow, blue, or purple, terminal
