A small group of greenhouse climbing-shrubs from New Holland, with Pea-flowers, of rather curious shape. So far as I am aware, only two species have any claim to being considered ornamental. They are free-growing plants, that succeed well in good fibrous loam, rather sandy, and are benefited by a little peat of good quality, when it can be got. They should be allowed to extend without summer-pinching, but when flowering is over the branches should be thinned out with the knife, so as to prevent overcrowding. Cuttings strike freely in a cool propagating-house, in very sandy peat and loam, under a bell-glass; they should be partly ripe before being put in. They succeed best when planted out in moderate space for the extension of their roots, and should be well drained, so as to have their growth thoroughly under control in the autumn. They are apt to grow too much when the roots are freely supplied with moisture late in the season, and therefore flower badly.
This is a pretty common greenhouse-climber, usually grown in pots, and trained to stakes or a wire-trellis; but which is much better planted out against the back-wall of a greenhouse or a pillar. The flowers are crimson, and appear in spring and early summer.
This sort has scarlet flowers, shorter than the last, but not less effective. It is scarcely so free a grower, and is therefore better adapted for pot-culture. Flowers in early summer. W. S.
