origin. It has lived here entirely uninjured for several years on the 
edge of the group of Yews on Hemlock Hill Road at the entrance of 
Yew Path, one of the most exposed positions in the Arboretum. This 
is certainly a plant of great value for this part of the country. 
Among the Junipers there are several dwarf forms of the arbores- 
cent species. Of our common Red Cedar, Juniperus virginiana , a form 
with branches spreading close to the ground grows at several places 
on the coast of Maine. The plants of this form in the collection are 
too young to show their habit; it has not yet received a name. The 
form globosa of the Red Cedar is a small, round, handsome shrub well 
worth a place in collections of these dwarfs. The var. tripartita, which 
is not rare in European nurseries, is a low broad shrub with spreading 
and erect branches forming a wide open head. There are a number of 
large plants of this form on the left of the entrance to the path which 
leads from Yew Path to the knoll on which the Juniper collection is 
established. 
Of Juniperus chinensis the best known dwarf form is the variety 
procumbens , with elongated branches spreading into wide mats. Of 
this species there are also in the collection plants of a dwarf form with 
erect stems forming small, round-topped shrubs. Of the European 
Savin (/. Sabina) the var. tamariscifolia is a vigorous prostrate shrub, 
and the variety humilis, which is the smallest of all the Junipers in 
the collection, is only a few inches high with small, spreading prostrate 
stems. 
Of the conifers of the Pacific coast, with the exception of Lawson's 
Cypress and the Douglas Spruce ( Pseudotsuga mucronata), no dwarfs 
have yet appeared, or, if they have appeared, they have not been mul- 
tiplied in nurseries; and this seems to be true of the Firs, Spruces, 
Pines and Hemlocks of Asia with one exception; this is the dwarf form 
of the Japanese Pinus densiflora (var. pumila) which is much cultivated 
in Japanese gardens and is one of the handsomest of all dwarf coni- 
fers. This little Pine, which sometimes grows to the height of six or 
eight feet and forms a head of spreading branches ten or twelve feet 
through, is perfectly hardy here and is now well established with a 
number of other dwarf conifers on Conifer Path. Unlike other dwarf 
conifers, this plant flowers freely and occasionally bears cones. There 
are dwarf forms of the common White Pine of the eastern states, 
Pinus Strobus, which are decorative plants, and several dwarf forms 
of the so-called Scotch Pine (P. silvestris) which are more pyramidal 
in habit than forms of the White Pine. The most commonly cultivated 
dwarf Pine, however, is the Mugho Pine (P. mughus or pumilio). This 
is a shrub of the mountains of central and southern Europe and a form 
of Pinus montana, growing sometimes with that tree as on the Pyre- 
nees, and sometimes, as on the Dolomites, by itself without other forms 
of the species. In cultivation it is a broad shrub with numerous erect 
stems occasionally reaching the height of fifteen feet and covered with 
dark green foliage. Plants in cultivation produce cones freely and the 
seedlings probably retain the habit of the parent. There are two quite 
distinct forms in the Arboretum collection, one with much coarser 
leaves than the other. This Pine is perfectly hardy and grows rapidly, 
but long before it reaches its full size it loses the lower branches and 
compact form which is the chief beauty of the young plants. 
No other conifer, with the exception, perhaps of the eastern American 
Arborvitae, has shown so great seminal variation as the European or Nor- 
way Spruce ( Picea Abies), and some of these forms are among the most
