PBAGTICAL GUIDE TO GABDEN PLANTS adenostoma 



G. stipulacea. — A perennial 1-2 ft. 

 high, with lanceolate deeply cut leaves, 

 and white flowers in June. 



Culture da. as above, p. 369. 



G. trifoliata (Spirma trifoUata). — A 

 Spirsea-like plant about 1 J-2 ft. high, with 

 3-parted leaves, and linear, entire, pointed 

 stipules. Flowers in June and July, red 

 or white. 



Culture Ac. as above, p. 369. 



KERRIA (Jew's Mallow). — A genus 

 with one or two species of slender-stemmed 

 deciduous shrubs with stalked, simple, long 

 pointed, largely and unequally toothed 

 leaves, linear awl-shaped stipules, and 

 large yellow, solitary, stalked flowers at 

 the ends of the branches. Petals 5, broad 

 oblong or rounded, shortly clawed. 

 Stamens numerous. Carpels 5-8, dry, 

 indehiscent. 



K. japonica. — ^A pretty Japanese shrub 

 3-4 ft. or more high, with bright green, 

 shining leaves, rather smooth above, paler 

 and slightly hairy beneath. Flowers in 

 spring and early summer, orauge-yeUow, 

 numerous. The double-flowered variety 

 is best known and is usuallj' seen trained 

 to walls. It looks well, however, grown 

 as a bush, the slender arching stems being 

 covered with yellow blossoms. There is 

 a beautiful variety with leaves variegated 

 with sea-green, pale yellow and white. 



Cultwre and Propagation. — Kerrias 

 thrive in any good soil. They may be in- 

 creased by layers, division of the roots in 

 early autumn or spring, or by cuttings of 

 the young shoots in sandy soil under a 

 glass. After flowermg the old wood may 

 be cut out where necessary and the young 

 shoots exposed to the light and air as 

 much as possible. 



RHODOTYPOS (White Jew's 

 Mallow). — A genus with one species 

 described below, with the generic charac- 

 ters : — 



R. kerrioides. — ^A charming deciduous 

 Japanese shrub, 5-15 ft. high, with 

 decussately opposite, stalked, ovate, 

 pointed, deeply serrated leaves, silky be- 

 neath. Flowers in May, white, herma- 

 phrodite, solitary, on short stalks at the 

 ends of the branches, numerous. Calyx 

 lobes 4, large, leafy, deeply serrated. 

 Petals 4, large, rounded, shortly clawed. 

 Stamens numerous. Carpels 1-4, drupe- 

 like, rown, shining, 1-seeded. 



Culture cmd Propagation, — This 

 species may be grown like the Kerria, 

 either as a bush or wall plant. It is in- 

 creased in the same way by layers, division 

 of the roots in early autumn or early 

 spring, or by cuttings of the young shoots, 

 and likes similar soil. Seeds are also 

 ripened freely in favourable seasons, and if 

 sown in cold frames as soon as ripe, or in 

 gentle heat in spring, vnH produce young 

 plants which may be pricked out and 

 transferred to the open ground when 

 strong enough. 



NEVIUSIA (Alabama Snow Wreath). 

 Another genus with only one species. 

 The follovvdng description includes the 

 generic characters ; — 



N. alabamensis. — A somewhat rare 

 and beautiful United States shrub with 

 alternate, stalked, ovate or oblong, doubly 

 serrate leaves, and small free stipules. 

 Flowers rather large, hermaphrodite, 

 white or yellowish-green, on slender stalks 

 along the length of the branches. Calyx 

 5-lobed, lobes leafy, serrated. Petals 

 none. Stamens numerous, conspicuous. 

 Carpels 4. Drupes 4, Pea-like. 



Culture and Propagation. — At Kew 

 this plant flowers freely in the open air, 

 and it will probably prove hardy in most 

 parts of the country. It thrives in warm 

 loamy soil, and may be treated like Neillia 

 or Bhodotypos. Propagation may be 

 effected by means of cuttings of the half- 

 ripened shoots in sandy soil under a hand- 

 light, or the lower branches may be 

 layered in autumn and severed from the 

 parent plant the following year when well 

 rooted. 



ADENOSTOMA.— A genus with 2 

 species of rigid, branched shrubs, with 

 Heath-like, linear, leathery, entire leaves, 

 solitary or clustered. Flowers herma- 

 phrodite, racemose or paniculate. Calyx 

 obconio, bell-shaped, 10-ribbed, leathery, 

 5-lobed. Petals 5, round. Stamens 12 

 (or 8-15). Fruit a leathery achene. 



A. fasciculata. — A Heath-like Cali- 

 fornian evergreen bush about 2 ft. high, 

 with the characters above described. 



Culture and Propagation. — It thrives 

 in a peat and loamy soil, and may be 

 increased by cuttings of the young 

 shoots in sandy soil under glass. This 

 plant is very rarely seen.
