by Professor Sargent in Japan in 1892, Malus zumi and M. Sargentii ; 
the former is a common tree on the mountains of central Japan and 
the latter is an inhabitant of the borders of salt marshes in Hokkaido. 
The dwarf habit of this species makes it a good subject for small gardens. 
The rather small flowers are produced in great abundance, and the dark 
red fruits remain on the branches until growth begins the following 
spring. Malus baccata is a common tree in eastern Siberia, and was 
one of the first of these plants introduced into Europe. It has no 
doubt played an important part in the introduction of many hybrid 
forms, including the so-called Siberian Crabs, like the “Transcendent” 
and many other well known varieties. These are supposed hybrids 
between the common Apple and Malus baccata-, among them are some 
of the most beautiful flowering plants in the whole Apple Group. The 
flowers are followed by brilliant fruits valuable in cooking and for pre- 
serves. The Siberian Crabs are hardier than any of the domestic 
Apples and have therefore been found valuable in some of the colder 
parts of Canada and the United States where other Apples cannot be 
grown. In cultivation Malus baccata is a tall narrow tree with small 
nearly white flowers and fruit about the size of a pea. There is a fine 
specimen of this tree in front of the gardener’s house in the Harvard 
Botanical Garden in Cambridge. It is impossible within the limits of 
one of these bulletins even to mention the names of all the species, 
hybrids, forms and varieties of these plants in the collection which has 
been in process of formation for nearly forty years and must now be 
one of the most complete in existence. It will well repay a careful 
study, especially the new collection at the base of Peter’s Hill. Few 
plants are better suited to the New England climate than the Crab- 
apples; they all produce beautiful flowers and many of them brilliant 
fruit. It should not be forgotten, however, that all Apple-trees are 
liable to be attacked and killed by the San Jose scale, and that it is 
unwise to plant them unless this pest can be kept in check by careful 
spraying. 
Early-flowering Honeysuckles. Some of the early Bush Honeysuckles 
are already in flower; indeed the pale yellow fragrant flowers of two 
Chinese species, Lonicera Standishii and L. fragrantissima have already 
fallen. These plants have long been favorites in the gardens of the 
middle and southern states where they grow to a large size and form 
round-topped shapely bushes. In New England, however, these plants 
are not always perfectly hardy and it is not usual for them to flower 
as well as they have this spring. Other species already in flower in 
the Shrub Collection are Lonicera tangutica, with small pink flowers, 
L. syringantha, var. Wolfii, with very fragrant violet-colored flowers, 
L. canadensis and L. utahensis, with pale yellow flowers, the geographi- 
cal forms of L. coerulea, with larger yellow flowers, and the beautiful 
Japanese L. gracilipes, with its drooping pink flowers. For another 
month, at least, different Honeysuckles will be opening their flowers, 
and these will be followed on many species by brilliant fruits which 
often make these plants conspicuous in summer and autumn. 
Currants and Gooseberries. Many interesting plants now in flower 
will be found among the Currants and Gooseberries ( Ribes ) in the Shrub
