MESSRS. JACKMAN'S CLEMATISES.
Messrs. Jackman & Son's popular exhibition at Regent's Park has now been brought to a close, and we may fittingly call attention at its termination to some of the charming novelties which it has been the means of introducing to our notice.  Amongst the later novelties of the patens group were... Baroness Burdett Coutts, also a pink, but paler than Miss Crawshay, and with a tendency to develope a second row of sepals.

Clematis. — Messrs Jackman, of Woking, staged about thirty plants of their new hybrid Clematises, which we admire the more, the more we see of them, so deserving are they of general culture, either in pots or planted out.  Among those staged on this occasion, we noted the following as distinct and good: C. Baroness Burdett Coutts, a large-flowered variety, of a delicate rosy lilac; Lady Stratford de Ratcliffe, a beautiful lavender-blue, large and fine; the Queen, a delicate lilac; and Vesta, an eight or ten-petalled flower, of remarkably good form and pearly whiteness, with purple stamens.  The majority of the plants were 18 inches to 2 feet high, and as much in diameter, bearing from thirty to sixty flowers each.

C. Baroness Burdett-Coutts (Jackman). — A stout-growing variety, apparently belonging to the lanuginosa type, but having an earlier-flowering habit.  The leaves are large, ternate, of a pale green colour, with broadly ovate leaflets, which some times become divided in the manner of those of the florida type.  It has the flowers of a pretty and delicate shade of Solferino-pink, with a creamy-white bar, and consisting of seven or eight broadly elliptic sepals, the stamens being pale-coloured, with whitish filaments, and pale brown anthers.  It is a very delicate and beautiful flower, and quite distinct in its character.
