This new Camellia cuspidata is the hardiest of the genus 

 and will be a welcome plant where it is just too cold for 

 the old C. Japonica 



and the flowers are rather small with slender stalks 

 and are borne a hundred or more together in one 

 truss. The other species have larger flowers pro- 

 duced in broad flattened or rounded masses. In 

 R. Rubus the leaves are 5-foliolate and hairy on the 

 underside; in R. Gentiliana they are 5-foliolate and 

 glaucous below; in R. Helenae 7-9-foliolate and 

 slightly hairy on the underside; in R. longicuspis 

 they are 7 to 9-foliolate, intense green and quite 

 smooth. There are of course other technical and 

 obvious differences which need not be related here, 

 but all are extremely floriferous, last in bloom for 

 more than a month and retain their foliage very late 

 in the season. No species of Rose are more- beauti- 

 ful in flower and foliage than these and one and all 

 with their cascades of pure white fragrant flowers 

 are delightful garden shrubs. Further, they offer 

 possibilities in the development of new races of 

 Roses which the hybridist can best appreciate. 

 With rose-pink flowers there is the pretty R. Will- 

 motiiae which is an erect-growing shrub with arching 

 branches, small gray-green leaves and flowers in 

 pairs or singly and the allied R. multibracteata with 

 larger and greener leaves and clusters of numerous 

 rose-colored flowers. There are other species, too, 

 but this half dozen must suffice for the time being. 



EVERGREEN COTONEASTERS 



A genus of ornamental shrubs which recent work 

 in China has vastly augmented is Cotoneaster. A 

 dozen or more new species with deciduous leaves 

 thrive amazingly in the Arnold Arboretum but some 

 half dozen, mostly with evergreen leaves, are not 

 hardy there. One of these C. pannosa flourishes in 

 and around San Francisco and Mr. McLaren told 

 me that he considered it one of the most valuable 

 plants of recent introduction. Closely allied to 

 that species is C. Harroviana which is a superior 

 plant with rather larger and thicker shining green 

 leaves, broader masses of flowers and wide-spreading 

 branches with red-purple stems. The Willow- 

 leaved Cotoneaster (C. salicifolia) is an erect shrub 

 growing 10-12 ft. tall with arching branches, pend- 

 ent whip-like branchlets, narrow shining green 

 leaves clothed with a felt of white hairs on the 

 under side and flat corymbs of flowers. Its variety 

 rugosa has rather shorter and broader leaves which 

 are undulate on the upper surface; the variety 

 floccosa has more narrow leaves and brighter red 



fruits than the type and the habit is more spreading. 

 The allied C. Henryana is a strong growing shrub, 

 10-15 ft. tall with spreading slender branches pend- 

 ent at the tips and relatively large leaves, rather 

 thin in texture, bright green above and slightly 

 downy and broad masses of white flowers which are 

 followed by small fruits. The above all have 

 showy flowers, brilliant red fruits and good foliage. 

 In C. Franchclii and C. amoena the flowers are 

 insignificant but the scarlet fruits are large and con- 

 spicuous and produced in great abundance. These 

 are much branched shrubs growing 6 to 12 ft. tall 

 with twiggy slender, gracefully arching and spread- 

 ing branches, and small leaves, dark green above 

 and gray below. Though normally deciduous the 

 leaves persist and retain their freshness through the 

 winter in mild climates. 



As a ground cover either on the flat or for steep 

 slopes C. Dammeri (better known as C. humifusa) is 

 a most valuable acquisition. It is perfectly pros- 

 trate and roots are freely emitted from the branches; 

 the evergreen leaves are rounded and small and in- 

 tense shining green, and the flowers, which are rela- 

 tively large and pure white, are produced singly or 

 severally together and are followed by bright scarlet 

 fruits. 



SOME HEDGE PLANTS 



The Japanese Photinia glabra and the Chinese 

 P. serrulata are much-esteemed evergreen shrubs 

 in California and the first named is a valuable hedge 

 plant. The new P. Davidsoniae is superior to either. 

 This is a shapely evergreen tree growing 40 to 50 

 ft. tall with dark glossy green leaves which are red- 

 dish when young, and white flowers borne in broad 

 flattened heads and followed by masses of scarlet 

 fruits. It is a great favorite among the Chinese 

 and in central China is commonly planted around 

 shrines and tombs. 



GORGEOUS SHRUBS 



Closely allied to Cotoneaster is Pyracantha of 

 which the European P. coccinea and its var. Lalandii ■ 

 are well-known and much appreciated shrubs on the 

 Pacific slope. The Chinese P. crenulata and P. 

 angustifolia are magnificent when in fruit. The first 

 named resembles the European species in habit but 

 has differently shaped leaves and the fruits vary in 

 color from red to orange-scarlet. The other is 

 upright in habit with rigid horizontally disposed 

 branches, and narrow, oblong dark green leaves. 

 The fruit is scarlet but in habit and general appear- 

 ance this new plant is very distinct. 



Not far removed in relationship from the above 



is Stranvaesia with green persistent leaves, which 

 in winter become beautifully tinted, and broad flat 

 heads of pure white Hawthorn-like flowers followed 

 by masses of scarlet to orange-scarlet fruits. There 

 are two kinds: S. Davidiana with rather large oblong 

 leaves and its variety undulata with much smaller 

 and narrower leaves. Both are much-branched 

 shrubs growing 5 to 15 ft. tall and as much in di- 

 ameter. Another pleasing shrub and one capable 

 of withstanding much drought is Osteomeles Schwer- 

 inae which has very small pinnately divided dark 

 green persistent leaves, showy white flowers and 

 black fruits. 



SOME NEW CORNELS 



Among the new Viburnums from China are a 

 number of very distinct and ornamental evergreen 

 species. One of the best is V. Henryi which is 

 a large much-branched shrub 10 to 15 ft. tall with 

 ascending and spreading branches, thick, glossy 

 green oblong leaves, erect pyramidate masses of pure 

 white flowers and beautiful fruits which as they ripen 

 change to coral-red, scarlet and finally jet black. This 

 new comer is one of the most strikingly handsome 

 members of a distinguished group. Very distinct too 

 is V. Davidii with dark green leathery leaves with 

 prominent veins. This is a low growing, branching 

 shrub seldom exceeding 2 ft. in height with broad 

 flat heads of pure white flowers which are succeeded 

 by indigo-blue fruits. It is very suitable for rocker- 

 ies and makes a good ground cover. Other species 

 with blue fruits are V. propinquum and V. Harry- 

 anum. The first-named is a loosely-branched shrub 

 growing 5 to 10 ft. tall and has shining green lance- 

 shaped leaves 2-4 inches long; the other is very com- 

 pact in habit with twiggy shoots and small deep 

 green rounded leaves and is totally unlike any other 

 Viburnum and closely resembles Box (Buxus) in 

 general appearance. Both have inconspicuous 

 greenish white flowers. Another fine evergreen 

 is V . coriaceum which is a large tree-like bush grow- 

 ing 15 to 25 ft. tall with ascending and spreading 

 branches clothed with large dull green leaves and 

 bearing in season trusses of creamy-white flowers 

 with conspicuous blue stamens and bloomy black 

 fruits. Very different is V. utile with flattened 

 round heads of fragrant flowers, pink in the bud 

 and pure white when fully expanded, and jet black 

 fruits. This is a much branched shrub growing 6 

 to 12 ft. tall, with twiggy branches, small, .thick 

 leaves, lustrous dark green above and gray on the 

 underside. This species grows naturally in rocky 

 places and withstands drought exceedingly well. 

 A remarkable Viburnum and totally unlike any 



This large flowered yellow Jasmine (/. primulinum) has already become well known to California gardeners,
