Geraniacete Tropczolum. 93 



4. T. Lobbidnum. A strong growing species, more like No. 

 2 in 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. edule. 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. tuberosum. A smaller plant than the last. Leaves 

 smooth, obtusely 5-lobed^ lobes rounded. Petals yellow within, 

 spur reddish-orange. 



7. T. pentaphyllum, syn. Chymocdrpus pentaphyllus. A 

 very distinct species with slender tortuous sterns. 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 Calif ornian species, only one of which is in general 

 cultivation. From \ipwj, a marsh, and civOos. 



1. L. Dougldsii. 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
