Papaveracea 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. G. 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. G. nobilis. 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. 



0. Marshalliana is a dwarf tuberous-rooted species from 

 Asia Minor, having pale yellow racemose flowers and a pair of 

 biternate leaves on each stem ; G. sotida 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 G. tuberosa, syn. G. cava, is similar to the last, with white 

 flowers and entire bracts. These two are both European species. 



ORDER IX.- CRUCIPER^l. 



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 Megacarpcea 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,
