PLAGIANTHUS LYALLI, a native of New Zealand (1871), and a member of the
Mallow family, is a free-flowering and beautiful shrub, but one that
cannot be recommended for general planting in this country. At Kew it
does well and flowers freely on an east wall. The flowers are
snow-white, with golden-yellow anthers, and produced on the ends of the
last season's branchlets during June and July. The flower-stalks, being
fully 2 inches long, give to the flowers a very graceful appearance. In
this country the leaves are frequently retained till spring.
P. LAMPENI.--Van Dieman's Land, 1833. This is about equally hardy with
the former, and produces a great abundance of sweetly-scented flowers.
P. PULCHELLUS (_syn Sida pulchella_).--Australia and Tasmania. Another
half-hardy species, which bears, even in a young state, an abundance of
rather small, whitish flowers.
