Geraniacee— Tropeolum. 93 
4, T. Lobbidnum.—A strong growing species, more like No. 
2in habit, but the leaves are slightly villous, and the orange 
and scarlet petals are fringed. Many of the beautiful bedding 
varieties belong to this species, though it is probable that some 
of them are of hybrid origin between this and the foregoing. 
Perennial tuberous-rooted Species. 
5. T. édule.—A climbing species with slender tortuous stems 
and leaves of 5 to 7 narrow lanceolate glaucous divergent lobes. 
Flowers orange or yellow. This and all of the perennial 
species are rather tender, and comparatively rare in gardens 
on account of the difficulty experienced in growing them. 
6. T. tuberdsum.—A smaller plant than the last. Leaves 
smooth, obtusely 5-lobed; lobes rounded. Petals yellow within, 
spur reddish-orange. 
7. T. pentaphyllum, syn. Chymocarpus pentaphgllus.—A 
very distinct species with slender tortuous stems. Leaves 
composed of five distinct oblong-lanceolate leaflets. In this 
species the calyx, especially the bright red spur, forms the 
most conspicuous part of the flowers, the petals being small, 
greenish in colour, and only two in number. The fruit of 
this, too, is more decidedly fleshy and juicy. 
4, LIMNANTHES. 
Diffuse glabrous annuals with alternate dissected exstipulate 
leaves. Flowers regular, pedunculate, solitary, axillary, white, 
yellow, or rose. Sepals 5, valvate. Petals 5, sub-perigynous, 
contorted. Stamens 10, free, inserted with the petals. Fruit 
of about 5 indehiscent indurated 1-seeded carpels. There 
are three Californian species, only one of which is in general 
cultivation. From Aduvn, a marsh, and dvOos. 
1. L. Douglasit.—A prostrate pinnate-leaved annual with 
yellow or white rather large sweet-scented flowers. 
5. OXALIS. 
Herbs, or rarely dwarf shrubs. Leaves usually 3-foliolate, 
sometimes plurifoliate or pinnate, stipulate or exstipulate, 
alternate. Flowers regular, on axillary or radical 1- or more 
flowered peduncles. Sepals 5, imbricate. Petals 5, contorted. 
Stamens 10, free or connate at the base. Disk none. Capsule 
5-celled, dehiscing loculicidally, valves adhering to the axis ; 
seeds one or more in each cell, albuminous. About 220 species
