r leaves, &c. It differs, however, in the
arrangement of the flowers, which are in a terminal umbel. The leaves of
_E. ciliaris_ are usually in threes at each node, and, of course, its
distribution in Britain is much more restricted than that of _E.
Tetralix_. There are other minor points of difference that need not be
referred to here. The "Cross-leaved Heath" grows 1 to 1-1/2 feet high,
and has bright rose-coloured flowers. There is a white-flowered variety
(_alba_), and a very pubescent one named _mollis_.

_E. Mackaii._--This is so closely allied to _E. Tetralix_ that it is
regarded merely as a variety by some authorities. It was first found in
Galway in Ireland, between Roundstone Bay and Clifden. It has since
proved to be a native also of Spain. It is a charming garden plant
flowering from July to September. The leaves have the same right-angled
arrangement as those of _E. Tetralix_, but the flower is shorter,
broader, and of a paler rose.

_E. vagans_ (Cornish Heath).--This Heath is one of the most useful of
dwarf evergreens, growing vigorously, especially when planted in good
soil. I think, however, it flowers better and has more of the typical
Heath character when in somewhat poor, sandy soil. In England it is
almost or quite confined to Cornwall, but occurs also in Ireland and
South-West Europe. It is especially valuable in the garden because it
flowers late, beginning in July and keeping on until October. Its
flowers are crowded in racemes 4 to 6 inches long, and they are pinkish
purple in colour. The plants may be kept neater and more compact by
removing the flowering portion of the shoots before growth recommences
in the following spring. Left to themselves, especially in soil that is
at all rich, the plants are apt to get straggling and unkempt.

_E. multiflora._--This belongs to the same type of Heath as _E. vagans_,
the Cornish Heath, but differs in its more compact growth and shorter
racemes of flowers. Although not so vigorous and showy, it may still be
preferred for some situations. It is a neater plant, and its lower
branches have not the same tendency to get sprawling and ungainly as _E.
vagans_. In other respects it is much like that species, the leaves
being of similar shape and arrangement, and the flowers of a paler
purple; the raceme, however, is only 2 inches or so long. _E.
multiflora_ is not found in Britain, but is a native of the country to
the north of the Mediterranean Sea from France
