plant is a native of the region in the neighborhood of St. Louis. The 
compact flower and fruit clusters readily distinguish it from allied 
species. 
Crataegus succulenta. This is a good representative of a peculiar 
group of Thorns {Tomentosae), distinguished from the other groups by 
the deep longitudinal cavities on the inner face of the nutlets of the 
fruit. The leaves of this Thorn are thick, lustrous, dark green, elliptic 
in outline, lobed only above the middle, and not brilliantly colored in 
the autumn. The flowers with twenty stamens and small rose-colored 
anthers hang on long slender stems in many-flowered clusters. The 
fruit is two-thirds of an inch in diametar, scarlet and very lustrous, 
and its beauty is increased by the contrast of color with the dark 
green leaves among which it is suspended. 
Crataegus fecunda. This is also a native of the St. Louis region and 
is a good representative of the great Crus-galli Group of which the 
well-known Cockspur Thorn is the type. C. fecunda is a large, round- 
topped tree with lustrous leaves broadest at the apex, small flowers 
with rose-colored anthers in many-flowered clusters, and abundant 
orange-red fruits which droop on slender stems. Other plants in this 
collection to which attention is called are C. prunifolia, C. Douglasii, 
the black-fruited species of the Puget Sound region, of which there 
is a large specimen here, C. rivularis from the southern Rocky Moun- 
tain region, a smaller tree also with black fruit, C. arkansana, C. 
Arnoldiana, C. Dawsoniana, and forms of the European C. oxyacantha. 
Crataegus on Peter’s Hill. A large number of Thorns in the Peter’s 
Hill Collection have flowered this year and several of them are now 
bearing good crops of fruit. Of special interest just now are the plants 
of the Intricatae and Unifiorae Groups, many of which are covered with 
fruit. These groups are of particular interest to gardeners for, with 
a few exceptions, they are small shrubs and begin to bloom when only 
a few years old. The flowers which usually open later than those of 
most of the Thorns, are large and showy with either yellow or rose- 
colored anthers. The fruit, which is large and usually sub-globose, is 
on different individuals scarlet, crimson, orange-color, green or yellow, 
and the leaves of most of the species turn late in October to beauti- 
ful shades of orange, red or scarlet. This group of shrubs is at the 
eastern base of Peter’s Hill on the lower side of the drive and near 
a large White Oak. Some of the species which are most attractive 
at this time are C. fruticosa, C. Bissellii, C. Peckii, C. Smithii, C. 
foetida, C. modesta, C. nemoralis, C. cuprea, C. intricata, C. Boyn- 
tonii and C. Buckleyi. Long overlooked by botanists, these little plants 
have not yet found the place in gardens which, when better known, 
they are destined to occupy. 
Crataegus punctata. There is a group of this Thorn on the southern 
side of the Overlook on Bussey Hill which well shows the variation in 
the color of the fruit on different individuals of this species. On some 
of these plants the fruit is red, and on others yellow, orange color or
