Papaveracee—Corydalis. 43 
9. CORYDALIS. 
This genus differs mainly from the last in having only one 
of the outer petals spurred or inflated, the other being flat, 
and in the inflated 2-valved capsule; the flowers are also 
smaller. The Greek name for Fumitory. Species numerous 
in the Mediterranean region, a few extending to America, 
South Africa, and north-western Asia. , 
1. C. lutea.—A common European plant, found naturalised 
in some parts of England. A perennial fibrous-rooted herb, 
about a foot high. Leaves on long petioles, ternately divided. 
Flowers yellow, in leaf-opposed racemes, from May to August. 
2. C. nébilis.-This is a fine large yellow-flowered species, 
a native of Siberia, producing its flowers in early Spring. It 
belongs to the tuberous-rooted section, and has unbranched 
stems about a foot high, and dense racemes of bright yellow 
flowers. 
C. Marshalliana is a dwarf tuberous-rooted species from 
Asia Minor, having pale yellow racemose flowers and a pair of 
biternate leaves on each stem; C. sdlida is a tufted species 
about 6 inches high, with biternate glaucous leaves and uni- 
lateral racemes of rosy flowers from the axils of laciniate bracts ; 
and (. tuberésa, syn. C. cava, is similar to the last, with white 
flowers and entire bracts. These two are both European species. 
Orver IX. CRUCIFERAE. 
This very natural group of plants is so well defined that very 
little difficulty is experienced in recognising its members. 
They are almost without exception annual or perennial herbs 
with stellate hairs, radical leaves in rosettes, and the’ cauline 
alternate, destitute of stipules. Flowers usually in terminal 
racemes, rarely solitary, commonly ebracteate. Sepals 4, of 
which two are often saccate at the base. Petals 4. Stamens 
6, tetradynamous (in Megacarpéa polydndra the stamens are 
numerous). Ovary 2-celled or transversely jointed. Seeds 
destitute of albumen. This order includes nearly 200 genera 
and 1,200 species, occurring in all parts of the world, and ex- 
tending to the polar limits of flowering plants, but especially 
abundant on the borders of the Mediterranean Sea. It is one 
of the most important to the vegetable gardener, including as 
it does the many varieties of cabbage, broccoli, turnip, radish,
