78 SEEDS AND PLANTS IMPORTED. 



45670 to 45691— Continued. 



45683. Prunus maackii Rupr. Amygdalacese. 



(Cuttings.) A Manchurian bird cherry up to 40 or more feet higli in 

 a wild state, very distinct through the bark of the trunli being smooth 

 and of a strilving brownish yellow color, and peeling like that of a birch. 

 It is different from ordinary bird cherries in the racemes coming on the 

 year-old wood and from the laurels in being deciduous. (Adapted from 

 Bean, Trees' and Shrubs Hardy in the British Isles, vol. 2, p. 2^.) 



45684. Prunus serrulata Lindl. Amygdalacese. Flowering cherry. 

 (Cuttings.) Forma 7-osea Wilson. Cultivated cherry which has been 



grown at the Arnold Arboretum. It was received from Spath in 1912 as 

 P. pseudo-cerasus shidaresakura Koehne. 



" Flowers rather small, inodorous, pink, and very double, known to me 

 only as a cultivated plant in this Arboretum. It is fortunate that 

 Koehne's name is a synonym, since in Japanese it signifies hanging 

 <"herry and in Japan is applied only to 1\ subhirtella var. pendula 

 Tanaka." {Wilson, The Cherries of Japan, p. 27.) 



45685. Prunus thibetica Franch. Amygdalacese. Plum, 

 (Cuttings.) An ornamental tree 15 to 20 feet in height, bearing oblong 



-convolute leaves which have crenate margins. The bluish pink flowers 

 appear with the leaves on pedicels one-third to three-fourths of an inch 

 long. Native to western China, where it commonly grows in thickets.

 meters altitude. It has comparatively small glabrous crenate leaves and 

 small flowers with two, rarely three, styles. The fruit is about 1 to 1.4

45688. Pyrus serrulata Rehder. Malaceae. Pear. 

 (Fruits.) A tree native to western Hupeh at altitudes from 600 to 



1,600 meters. 



" This species seems to be most closely related to Pyrus serotina Reh- 

 der, but differs chiefly in its serrulate, not setosely serrate, generally 

 broader leaves and in the smaller flowers with usually three or four 

 styles and shorter sepals, and in the smaller fruit." {Sargent, Plantae 

 Wilso7iianae, vol. 2, p. 263.) 



45689, RiBES fasciculatum CHiNENSE Maxim. Grossulariacese. Currant. 

 (Plants and fi-uits.) "In the shnib collection the leaves of two cur- 

 rants are just turning scarlet [November 1, 1912]. These are Ribes 

 curvatnm and the Chinese form of Ribes fasciculatum. The beauty of 

 the Chinese currant at this season is increased by the bright-red fruits 

 which are still on the branches. It is the only representative of the 

 genus in the collection with fruit which ripens in the autumn and is
