CEEATONIA 



ROSE ORDER 



CEKCis 355 



polygamous, or dioecious, in short racemes. 

 €alyx bell-shaped, with 5 short segments. 

 Petals none. Stamens 5. Pod flattened, 

 thickish, leathery, about 4 in. long, rusty 

 colour, yielding a pulp which is eaten 

 sometimes in this country by children. 



CuUiM-e and Propagation. — This tree 

 grows well in the mildest parts in warm 

 sheltered spots. It may be increased by 

 seeds or by cuttings inserted in sand 

 under a glass during the late summer or 

 autumn months, and protected during the 

 winter. 



CERCIS. — A genus with 6 or 7 species 

 of imarmed, ornamental, deciduous trees 

 or shrubs, distinguished by their simple 

 kidney-shaped or cordate leaves, with 3 or 

 many nerves. Flowers usually produced 

 in clusters along the branches of one, 

 two, or more years' growth. Calyx more 

 or less bell-shaped, very short, and 

 broadly 5-toothed. Petals 5, somewhat 

 Pea-like. Stamens 10, free, bent down. 

 Pod oblong, or broadly linear, flattened. 



Culture amd Propagation. — These 

 trees like a deep rich sandy well-drained 

 «oil, and are fine plants for shrub- 

 beries or even alone on grass. When 

 well established they are covered with 

 flowers and may be justly regarded as 

 amongst the finest flowering trees or 

 shrubs in cultivation. They are usually 

 increased by seeds sown in spring in gentle 

 heat, but it takes 3 or 4 years to obtain 

 a flowering plant. They are sometimes 

 multiplied by layers. As old plants do not 

 bear being transplanted very well, it is 

 better to secure the permanent positions 

 for Cercises while they are still young, say 

 about 2 or 3 years old. 



C. canadensis. — A Canadian tree 

 12-20 ffc. high, with heart-shaped, pointed 

 leaves, bearded in the axils of the veins 

 beneath. The deep red and bright rose 



flowers appear in May in clusters along 

 the trunk and branches before the leaves 

 are developed. 



Culture Ac. as above. 



C. chinensis (0. japonioa). — A 

 Japanese and Chinese species closely 

 resembling the preceding in habit and 

 fohage, but has larger pink or deep purple - 

 red flowers, and is probably not quite hardy 

 except in the milder parts of the country. 

 The roundish ovate leaves taper rather 

 abruptly to a point, and are about 4 in. 

 across, and there are about 6 or 8 flowers 

 in each cluster. 



Culture dc. as above. 



C. Siliquastrura {Judas Tree; Love 

 Tree).— A native of S. Europe 20-30 ft. 

 high, with smooth, bluntly heart-shaped, 

 emarginate leaves 3-4 in. across and of a 

 blue-green hue, and clusters of bright 

 purple, pale rose or whitish flowers in 

 Ma5'. There is a form of the Judas tree 

 with variegated leaves. 



Culture dc. as above. In unfavourable 

 parts of the country this tree is best 

 against a wall. 



The following species of Cercis are 

 known to botanists, but are not yet culti- 

 vated in the British Islands. 



C. Griffithi. — A trailing shrub native 

 of Afghanistan where it grows at an eleva- 

 tion of over 10,000 ft. It has smooth 

 kidney-shaped emarginate leaves. 



C. racemosa.— A distinct and hand- 

 some Chinese tree about 20 ft. high, with 

 roundish leaves 2-4 in. long and broad, 

 downy beneath. From 10 to 30 flowers 

 are borne on racemes about 4 in. long. 



C. texensis. — A shrub or small tree, 

 native of the Bio Grande valley, and thus 

 probably somewhat too tender for outdoor 

 cultivation in the British Islands. It has 

 heart-shaped reniform leaves, and clusters 

 of rosy-pink flowers. 



XXXIX. ROSACEiE— Rose Order 



A large order containing 1,000 species or more of erect or prostrate herbs, 

 ■shrubs or trees, rarely climbers. Leaves various, simple or compound, alter- 

 nate or rarely opposite, stalk often dilated at the base. Stipules 2, free or 

 adhering to the leaf stalk. Flowers usually regular and hermaphrodite. Calyx 

 free or adnate to the ovary, usually 5-lobed, imbricated and persistent. Petals 

 5, rarely none, inserted under the margin of the disc, imbricate. Stamens 

 usually numerous, inserted vrith petals. Carpels 1 or many, free or united, 

 and more or less adnate to the calyx-tube. Fruit various, superior, or more
