63342. Betula maximowicziana Regel 

 (B. moximoioic.zii, Regel, not Rupr. ) . 

 Betulaceae. Birch. 



Mr. Mottet remarks that this is with- 

 out doubt the most beautiful of all the 

 birches, characterized by the rapidity of 

 its growth, the luxuriance of its foliage, 

 and the yellow color of its bark. I saw 

 a specimen at Kew and think it is one of 

 the handsomest birches I have seen. 



63343. Buddleia paniculata Wall. Lo- 

 ganiaceae. Butterfly bush. 



An Indian shrub, 6 to 15 feet* high, 

 with hairy branches and leaves and rather 

 dense panicles of lilac-colored flowers. 

 Probably best suited for the warmer 

 parts of the United States. 



63344. Caragana boisi C. Schneid. Faba- 

 ceae. 



A handsome bush 10 to 12 feet high, 

 with long, arching branches, native to 

 Szechwan and eastern Tibet, China. In 

 May the light-green foliage and numerous 

 yellow flowers make this an especially 

 attractive ornamental. 



For previous introduction, see S. P. I. 

 No. 56808. 



63345. Carpixus betulus L. Betulaceae. 



European hornbeam. 



Var. carpinizza. A wild, Hungarian 

 variety of the common European horn- 

 beam, differing from the type in having 

 its leaves more heart-shaped. 



. Carpinus turczaninovii ovalifo 

 lia Winkler. Betulaceae. Hornbeam, 



A shrubby tree, native to northern 

 China, and said to resemble closely Car- 

 pinus polyneura. The latter is a hand- 

 some, hardy tree of elegant habit, with 

 dark-green, sharply toothed leaves and 

 fruit clusters up to 2 inches in length. 



63347. Celastrus dependens Wall. Ce- 

 lastraceae. Bittersweet. 



A climbing shrub, native to the warmer 

 portions of the Himalayas at altitudes of 

 1,000 to 4,000 feet The membranous 

 leaves are very variable in shape, and 

 the yellowish green flowers are in termi- 

 nal, pendulous panicles An oil used in 

 India for illuminative purposes is ex- 

 pressed from the seeds. 



63348. Celastrus flagellaris Rupr. Ce- 

 lastraceae. Korean bittersweet. 



A shrubby Chinese vine, quite hardy, 

 with persistent spiny stipules, small oval 

 leaves, and small axillary fruits with 

 crimson arils. 



63349. Celastrus rosthorniana Loese- 

 ner. Celastraceae. 



A Chinese plant described (Plantae 

 Wilsonianae, vol. 2, pt. 2) as a climbing 

 shrub 15 to 20 feet high, with thick, 

 shining leaves, greenish white flowers, 

 and orange-yellow fruits. It is fairly 

 common in western Szechwan, China. 



63350. Celtis tournefortii Lam. Ulma- 

 ceae. Oriental hackberry. 



A tree about 20 feet high, or some- 

 times only a shrub, with oval, sharp- 

 pointed bluish green leaves 3 inches long 

 or less and small, reddish yellow fruits. 

 It is native to Asia Minor and is probably 

 not hardy north of Washington, D. C.

63351. x Clematis globulosa Hort. 

 Ranunculaceae. 



A hybrid of Clematis douglasii scottii 

 and C. texensis, with deep-purple, pitcher- 

 shaped flowers. Both of the parents of 

 this European hybrid are native to the 

 western United States. 



63352. Clematis integrifolia L. Ranun- 

 culaceae. 



Var. hybrida velleda. An erect, herba- 

 ceous clematis, becoming 3 feet high, 

 with broad, entire, oval leaves and soli- 

 tary nodding blue flowers. 



63353. Clematis tangutica (Maxim.) 

 Korsh. Ranunculaceae. Clematis. 



The handsomest yellow-flowered Cle- 

 matis in cultivation, the largest flowers 

 being about 4 inches across. The species 

 reaches a height of 8 to 10 feet and 

 bears gray-green leaves and solitary rich- 

 yellow flowers, with long, slender-pointed 

 sepals, downy outside and at the edges. 

 Native to northern and western China. 



63354. Corylus tibetica Batal. Betula- 

 ceae. Hazelnut. 



This remarkable species, with spiny 

 involucres somewhat resembling the burs 

 of a chestnut, was introduced into the 

 Vilniorin Fruticetum from Kansu, China, 

 in 1885. It is in flower and there are 

 many catkins now (middle of January) on 

 the shrub. It hybridizes freely with the 

 other species here in the Fruticetum and 

 may prove of distinct value for breeding 

 purposes, but the nuts are too small to 

 be of commercial importance. 



63355. EUONYMUS BUNGEANUS SEMIPER- 



sistens (Rehder) C. Schneid. Celas- 

 traceae. 



A large glabrous shrub or small tree, 

 from 3 to 5 meters high, with bright- 

 green, half-evergreen leaves of a bluish 

 or grayish hue. The yellowish white 

 flowers appear in loose, 3 to 7 flowered 

 cymes, and the few fruits are bright 

 pink. This variety differs from the typi- 

 cal, species in having leaves which re- 

 main on the plant until midwinter. 



63356. Euonymus sanguineus Loes. Ce- 

 lastraceae. 



The dull-green, serrate leaves and 

 large, pink fruits of this hardy Chinese 

 shrub or small tree make it an attrac- 

 tive ornamental for the northern United 

 States. 



63357. Evodia hupehensis Dode. Ruta- 

 ceae. 



A very common tree in the woodlands 

 of western Hupeh, China, according to 

 E. H. Wilson (Plantae Wilsonianae, vol. 

 2, pt. 1), where it grows to a height of 

 20 to 40 feet. It has smooth, gray 

 bark, spreading branches, and white flow- 

 ers in large flat corymbs. 



Fraxinus mariesii Hook. f. Olea- 

 ceae. Ash. 



A handsome, free-flowering shrubby 

 Chinese ash which has narrowly oval 

 leaflets with yellowish green lower sur- 

 faces. It blooms even when quite young ; 

 the upright panicles are about 5 inches 

 long.
