GILLENIA 369 



mollis (formerly known as Spircea capi- 

 tata) is a form with downy leaves. 

 Culture (to. as above. 



N. rubiflora and N. thyrsiflora, natives 

 of Nepaul, are not yet well known, nor are 

 they c[uite hardy in northern parts of this 

 country. The last-named species is a 

 Spirsea-Hke bush about 2 ft. high with 

 bright purple-red stems, and lobed and 

 serrate leaves which assume beautiful 

 purple tints in autumn. 



Culture dc. as above. 



N. Torreyi (or Spircea monogyna) 

 resembles N. opulifoKa, but has a more 

 compact habit, and grows only 2-3 ft. high. 



Culture dc. as above. 



STEPHANANDRA.— A genus with 

 only 2 or 3 species of shrubs, with alter- 

 nate leaves and hermaphrodite flowers. 

 Calyx lobes and petals 5. Stamens 10. 



Cultv/re and Propagation. — This is 

 practically the same as for the Shrubby 

 Spiraeas. The plants like a rich loamy 

 soil thoroughly well-drained and rather 

 moist than dry on the whole. The addi- 

 tion of a dressing of manure every autumn 

 or winter is very beneiicial. They may 

 be increased by dividing the roots in early 

 autumn, or in mild weather in spring. 

 Cuttings of the half-ripened shoots wiU 

 also root about August in sandy soil under 

 a handhght, and the plants thus obtained 

 may be transferred to the open air the 

 following spring. 



S. flexuosa (Spircea incisa). — A 

 deciduous Japanese shrub, with alter- 

 nate, stalked, incised or pinnatifid leaves, 

 I3-3 in. long, somewhat triangular in out- 

 line, and downy beneath. Stipules leafy, 

 persistent. Flowers in July, white, small, 

 in corymbose panicles or racemes. 



Culture dc. as above. When well- 

 grown this is a graceful bush 3-8 ft. high, 

 with long arching shoots and prettily cut 

 foHage. It is best grown in masses by 

 itself or even as single specimens on the 

 grass. It sends out suckers freely from 

 the roots, and may be also increased by 

 this means. 



S. Tanakae. — A Japanese shrub some- 

 what coarser growing and more fleshy 

 than 8. flexuosa, and with larger leaves 

 4-5 in. long, sharply toothed, but not 

 deeply lobed. Flowers small and greenish, 

 in loose panicles, not very attractive. 



Culture dc. as above. 



EXOCHORDA (Pearl Bush). — A 

 genus with only one or two species of 

 shrubs closely related to the Spiraeas in 

 character. 



E. grandiflora {Spi/rcea gramdiflora). — 

 A handsome Chinese shrub, 6 ft. high, 

 with stalked, lance-shaped oblong entire or 

 serrulate leaves and no stipules. Flowers 

 in May, polygamous dioecious, white, large, 

 in axillary racemes. Calyx bell-shaped, 

 4-5-lobed, rounded. Petals 4-5, large, or 

 rounded, shortly clawed. Stamens 15, 

 short, inserted at the mouth of the calyx. 

 Carpels 5, immersed in the calyx tube but 

 free from it ; when ripe, hoary, compressed, 

 ribbed. 



E. Alberti is a recently introduced 

 species from Persia, scarcely yet known, 

 although grown at Kew. It is quite 

 hardy and a vigorous grower, and 

 reaches a height of 10-12 ft., very much 

 resembling E. grandAflora in appearance. 

 The leaves however are larger and of a 

 brighter green, and the scentless flowers 

 are of a purer white but not quite so large. 

 As stated above, there are 15 stamens in 

 the flowers of -B. grandAfiora, but in 

 E. Alberti there are 25, arranged in 

 5 bundles. 



Culture cmd Propagation. — The Pearl 

 Bush likes a warm rich loam and a some- 

 what sheltered position. It may be in- 

 creased by seeds, layers, cuttings of the 

 half- ripened branches, or suckers from the 

 roots. It is a graceful plant for small 

 groups on the grass, and when it bears 

 its white blossoms, each about 1 j in. across, 

 it reminds one of a small single-flowered 

 Eose. 



GILLENIA. — A genus with 2 species 

 of erect hairy perennials, with almost ses- 

 sile 3-foliolate leaves and axillary or termi- 

 nal hermaphrodite flowers on long stalks. 

 Calyx tube cylindrical, 10-nerved, with 5 

 erect teeth. Petals 5, linear lance-shaped. 

 Stamens 10-20. Carpels 5, distinct or 

 united. Follicles 5, leathery. 



Culture and Propagation. — GUlenias 

 are natives of N. America and thrive in 

 moist peat and loam in partial shade, and 

 may be grown under taller plants in the 

 shrubbery. They may be increased by 

 dividing the roots in spring every three or 

 four years when the plants have made 

 good clumps. Seeds may also be sown as 

 soon as ripe in cold frames, and the seed- 

 lings transplanted in mild weather the 

 following spring.
