not before in the Arboretum been more covered with flowers than it 
has been this year, and certainly no shrub of recent introduction into 
our gardens better deserves a place in them. Another plant of this 
race known as “Eximea” is also flowering well this year. It differs 
in its more compact clusters of rose-colored or reddish flowers which 
on opening become light pink. 
Although still little known as a wild or as a garden plant, another 
northern species, Syringa Woljii, promises to be valuable in early sum- 
mer gardens. It reached the Arboretum in 1906 from Petrograd where 
it had probably been sent from northern Korea or Manchuria by the 
Russian traveler Komarov. The foliage resembles that of S. villosa, 
but the flowers are arranged in much larger clusters and are smaller 
and violet purple; their color is not unlike that of the hybrid “Lutece” 
but they are smaller and in denser clusters. Syringa Sweginzoivii, an 
other north Chinese plant, came to the Arboretum from Petrograd in 
1910. With each succeeding year the estimate here of the beauty and 
value of this plant is increased. It is a tall narrow shrub with slender 
erect stems, dark dull green pointed leaves, and long narrow flower- 
clusters; the flowers are delicately fragrant and half an inch long, with 
a slender corolla-tube and flesh-colored in the bud are nearly white 
after the buds open. Even very small plants of this Lilac flower freely. 
Not very unlike this species in habit, Syringa yunnanensis from south- 
western China differs in its more fragrant flowers which are white, 
faintly tinged with rose color. Another related species, Syringa micro- 
phylla, is interesting because, unlike other Lilacs, it flowers in the Ar- 
boretum twice during the year, once the middle of June and a second 
time in October. The flowers are nearly white and pleasantly fragrant. 
Syringa tomentello, an older name for the plant later called Syringa 
Wilsonii, is a tall, vigorous, fast-growing shrub with erect stems, 
dull green leaves, and open, long-branched panicles of pale rose-colored 
flowers. Syringa Julianae, like the last a recent discovery in western 
China, is a late flowering plant closely related to the north China S. 
pubescens. It has the same shaped flowers with the long narrow corolla- 
tube, but they are arranged in a shorter cluster, and are less fragrant 
than those of the northern plant. The beauty of the flower-clusters of 
S. Julianae is increased by the contrast between the violet purple color 
of the outer surface of the corolla and the white inner surface of its 
lobes. Two new species, Syringa reftexa and S. Sargentiana, discovered 
by Wilson in western China, with leaves very similar to those of Syr- 
inga villosa, are blooming rather more freely this year than before, 
although the Arboretum plants may be expected to be more prolific as 
they grow older. Syringa rejiexa is a conspicuous plant at this season of 
the year, for unlike those of all other Lilacs the flower-clusters are 
gracefully arching and pendent on long stems; they are cylindric, very 
compact, unbranched, and rarely more than an inch and a quarter in 
diameter. The flowers are deep rose color with a long slender tube and 
the odor of those of S. villosa. In habit Syringa Sargentiana resembles 
S. rejiexa, but differs from that species in the large, long-branched 
flower-clusters which are erect, spreading or nodding, and sometimes 
eighteen inches long and twelve inches across. The flowers are rather 
paler in color than those of S. rejiexa and white on the inner surface
