others mentioned in catalogues have 

 become intermixed by the crossing of D. 

 grandiflora and D. rosea. The variety 

 called prmcox has deep rosy flowers with 

 a carmine and yellow throat, and is a 

 very valuable shrub owing to the fact that 

 it comes into bloom early in May, nearly 

 a month before the other forms. 



Culture dec. as above. 



D. hortensis. — A Japanese shrub 4-5 

 ft. high, with stalked, ovate, pointed, softly 

 hairy leaves, having crenate or crenate- 

 serrulate edges. Flowers red or white, 

 slightly hairy outside and borne in great 

 profusion in May and June. The variety 

 nAvea has pure white flowers and is a 

 remarkably handsome bush. 



Culture dc. as above. 



D. Lonicera (D. cwnadensis). — A N. 

 American shrub 3-4 ft. high, with creep- 

 ing roots, and short-stalked, ovate-pointed, 

 serrate, smooth leaves, bright tinted in 

 autumn. Flowers in summer, yeUow. 



Culture dc. as above. 



D. middendorfiana. — A Siberian shrub 

 with nearly sessile, ovate-lance-shaped, 

 finely netted leaves, 2^-3^ in. long, 

 sharply serrate on the margins and hairy 

 on the nerves. Flowers in terminal 

 panicles, yellowish-white, the lower petal 

 dotted with pink. 



Culture dc. as above. 



D. rosea. — A Chinese shrub about 6- 

 ft. high, with ovate lance-shaped, serru- 

 late leaves. Flowers in spring, rose or 

 white, numerous. There are many fine 

 varieties, including noma, noma am/fea, 

 (with young leaves golden-yellow), Stelz- 

 neri, Lamallei, Looymanei &e. It may 

 be remarked that aU the forms of D.. 

 grwndiflora, D. amabilis, and X>. rosea 

 are now placed under one specific name,, 

 to wit, D.florida, acoordiog to the 'Kew 

 Handlist.' 



Culture dc. as above. 



D. sessilifolia. — A handsome hardy 

 shrub 8-5 ft. high, native of the mountains 

 of N. Carolina. The ovate tapering acute 

 leaves with serrate margins are about 3 

 in. long, and sit opposite each other on 

 the stems without stalks. The yellow 

 flowers, although individually little more 

 than i in. across, are borne in great 

 abundance in June on short-stalked 

 cymes, and are decidedly attractive. 



Culture dc. as above. Being a com- 

 paratively recent introduction, but httle 

 can be said as to the behaviour of this 

 distinct yellow-flowered species. It seems 

 however to be hardy in the milder parts 

 of the kingdom, and will doubtless 

 succeed under the same conditions as the 

 other species. There is a form of it called 



LIX. RUBIACEiE— Woodruff Order 



A large order with about 340 genera and over 4,000 species of erect, trailing,, 

 or climbing trees, shrubs, or herbs, very few of which are hardy. Leaves 

 simple, opposite or whorled, entire, serrated, toothed, or pinnatifid-lobed. 

 Stipules persistent or deciduous, free or adnate to the leaf stalk. Flowers 

 usually hermaphrodite and regular. Calyx-tube adnate to the ovary ; Umb 

 superior, somewhat cup-like or tubular, entire, toothed or lobed. Corolla 

 gamopetalous, funnel-shaped, salver-shaped, bell-shaped, or rotate, smooth or 

 hairy within. Stamens as many as the corolla lobes, rarely fewer, inserted in 

 the tube. Fruit a capsule, berry, or drupe, 2-10 seeded. 



The Bouvardia, Gardenia, Coffee and Cinchona belong to this order, but 

 cannot be regarded as hardy plants in the British Islands. 



unequally 4-5-toothed, or 4-lobed. Corolla, 

 tubular or funnel-shaped, quite smooth, 

 or hairy in the throat, and having 4 erect 

 or spreading lobes. Stamens 4. 



C. occidentalis A handsome decidu- 

 ous shrub 5-6 ft. high, native of North 

 America. The ovate tapering leaves are 



CEPHALANTHUS.— A small genus 

 of erect-growing shrubs or small trees 

 with round or bluntly 4-angled stems. 

 Leaves opposite or 3-4 in a whorl, shortly 

 stalljed, oblong or ovate lance-shapcd, 

 with short stipules between the stalks. 

 Flowers in round compact heads. Caly.K
