just matured their effect is very striking. The 
leaves are large, oval, and dark green. This 
kind is associated with the name of George 
Ellw^anger, the well-known nurseryman of 
Rochester, N.Y. 
C. ferentaria forms a tall handsome shrub 
with stout stems of 1 5 to 1 8 feet, and is com- 
mon in the Genesee Valley. The flowers, with 
10 stamens and creamy-yellow anthers, on 
shaggy, hairy, large corymbs, open towards 
the end of May. The small fruits of a glow- 
ing crimson hang in broad drooping clusters, 
and are fully coloured from about the middle 
of September and soon fall. The leaves turn 
to a fine yellow in the autumn and fall earlier 
than in most Hawthorns. 
C.formosa is a tall branching shrub of 12 
to 15 feet, with a spreading head. It is not 
uncommon about Rochester, Buffalo, and 
Niagara Falls. The large showy flowers with 
20 stamens and white anthers gathered into 
smooth thin corymbs, come into bloom about 
the last week in May, and the glaucous fruits 
ripen in October. The foliage is of a distinct 
yellowish-green throughout the season. 
C. Holme siana is frequently a tree 30 feet 
in height, with upright branches and usually 
forming a broad compact head. It is found 
from Central New York to Quebec. The 
cup-shaped flowers, with 5 to 8' stamens and 
purple-red anthers, open about the middle of 
May. Thebright crimson lustrous fruits ripen 
and fall early in September. The leaves are 
yellowish-green in colour, with prominent 
lobes and long sharp teeth. 
C. Lafieyi forms a tall shrub of 10 to 12 
feet, with slender, spreading branches. This 
kind seems to be rare, only two or three trees 
being known in Genesee Valley park, where 
it was first found. The large flowers with 1 5 
stamens and white anthers, on large corymbs 
covered with shaggy hairs, come into bloom 
during the first week of June, and the orange- 
red fruits ripen in October. 
C.pedicillata is abundant from western New 
York to Toronto. The flowers, with rose- 
coloured anthers, are gathered into loose long- 
stalked corymbs which expand about 25th 
May. The bright scarlet fruits ripen early 
in September and fall about the middle of 
the month. The leaves are broadly-oval and 
rich dark green in colour. Prof. Sargent re- 
gards this as " one of the largest and most 
beautiful thorn-trees of the northern United 
States." 
C. T*ringlei is widely distributed through- 
out western New York and Ontario — Canada. 
It forms a dense oval compact head, branch- 
ing 2 to 3 feet above the ground and reaching 
a height of 20 to 30 feet. The lo-stamened 
flowers with pink-red anthers open about the 
middle of May . The dull-red fruits — occasion- 
ally marked with yellowish freckles — hang in 
drooping clusters which ripen about the end 
of August and fall from a fortnight to three 
weeks later. This Hawthorn is readily dis- 
tinguished by its drooping leaves and their 
convex form, due to the infolding of the sides 
towards the mid-rib. 
C. spissijiora sometimes attains the size of 
a tree but is commoner as a shrub from western 
New York to Toronto. The flowers, with 10 
stamens and purple-red anthers, are borne in 
dense short clusters, and come into beauty just 
after the middle of May. The bright scarlet 
almost pear-shaped fruits are borne on short 
stalks in dense clusters, which begin to colour 
about the end of August and are not fully ripe 
till the middle of September. The foliage of 
this kind is ample and the fruit remarkably 
handsome when ripe.

PSYCHOTRIA. 
A LARGE group of tropical plants num- 
bering at least 5 00 kinds, which include 
small evergreen trees, bushes, and per- 
ennial herbs, of shrubby, climbing, or 
twining habit. Though found in almost 
all the warmer parts of the world they 
are commonest in Central and South 
America and the West Indies, while the 
clumsy botanical name has reference to 
the medicinal value of certain kinds. 
Very few of these plants have ever been 
grown in this country, the best known 
being the beautiful hothouse plant Psy-
