63 
quarters of an inch in diameter. It is probably a form of C. orientalis 
with fruit of an unusual color. 
Late Sowers. Chrysanthemum sibiricum, which has been flowering 
for several weeks on Azalea Path, will continue to open its white flow¬ 
ers until the buds are killed by a hard frost. This attractive plant is 
still rare in gardens, although it was introduced into this country four¬ 
teen years ago by Professor Jack who found it on Poukan-shan, the 
mountain close to the city of Seoul. This late-flowering Chrysanthemum 
is perfectly hardy; it produces seeds freely, and spreads also by under¬ 
ground shoots, so that once established it is likely to be a permanent 
feature in the garden. It is a shrub eighteen or twenty inches tall, 
with slender stems, woody at base, deeply divided, pale green, pun- 
gently aromatic leaves and white dais3’-Iike flowers an inch and a half 
in diameter. A form with pale rose-colored flowers has been raised in 
this country. A handsomer plant now in bloom is Chrysanthemum 
nipponicum which is commonly cultivated in Japanese gardens and 
which is believed to grow naturally on the shores of some of the 
smaller islands of northern Japan. It is a stout-stemmed, compact- 
round-topped shrub which under conditions favorable to it grows from 
two to three feet tall and three or four feet through. The leaves are 
narrowly oblong-obovate, sessile, slightly toothed toward the apex, light 
green and lustrous above, pale below, and thick and leathery; they stand 
erect, and pressed close against the stem display only their lower sur¬ 
face. The flowers are produced on long stout stalks, each from the 
axil of one of the upper leaves; and as the flower-stalks increase in 
length from the lowest to the one in the axil of the topmost leaf the 
flowers are arranged in a broad flat cluster in which buds continue to 
open during many weeks or until they are destroyed by cold. The flowers 
are daisy-like with broad, pure white ray-flowers, and are from two to 
two and a half inches across. The flowers of this Japanese Chrysanthe¬ 
mum are sometimes injured in Massachusetts by October frosts. It is 
better suited, like the Japanese Anemone, to regions which enjoy a 
longer autumn than that of Massachusetts. It grows well in the neigh¬ 
borhood of Philadelphia and there are good plants on Long Island. 
With the protection of a pit or a cool greenhouse it would probably con¬ 
tinue to open its flower-buds until Christmas. 
The Mountain Halesia or Silver Bell Tree. Until the beginning of 
the present century the botanists who visited the high Appalachian 
Mountains appear to have taken it for granted that the Halesia which 
grows at altitudes above 2500 feet was the same as the bushy tree of 
the foothills and upland valleys of the Piedmont region and southward. 
This idea having been generally accepted and as the lowland plant had 
for more than a century been common in gardens no attempt was made 
to cultivate the mountain tree, and the gardens of the United States 
and Europe have been deprived of one of the handsomest trees of the 
North American forests. The lowland plant, Halesia Carolina , is 
usually shrubby in habit with numerous stout stems wide-spreading 
from a short stem, and covered with nearly smooth or slightly scaly 
bark. The tree of the high mountains is not rarely eighty or ninety 
feet high with a straight trunk sometimes three feet or three feet and
