Order IV. CRUCIFER^. 



Herbs, sometimes shrubby plants, with a pungent watery juice, 

 and regular flowers ; known from all others by the 4 sepals and 4 petals, 

 along with hypogynous tetradynamous stamens (i. e. 6, two of which 

 are shorter than the other four), the fruit (called a silique, or where 

 short a silicle) a 2-celled capsule but with 2 parietal placentae. But in 

 two of the genera the silicle has only a single seed in each cell. Em- 

 bryo variously folded: no albumen. — A large order in cool regions^ 

 well known by such representative as the Mustard (Sinapis nigra and 

 S. alba), Water-Cress (Nasturtium officinale), Eadish (Baphanus sati- 

 vus) ; Cabbage and Turnip (Brassica oleracea and B. Bapa) &c. 



SiUquo slender, several seeded, . ^ 1. CABDAMHiTE, 



Silicle only 2 - seeded,^ 



Very flat, opening by 2 valves disdiarging the seed^ 2. Lepidium. 



Two-lobed,. splitting into 2 closed pieces, .......... 3. Sekebieba.. 



1. CARDAMINE Linn. [Paihi.] 



Pod linear, fliittened, usually opening elastically from the base ;

 southern hemispheres. 



i. C. iiiRSUTA Linn. (Enum. iVo. 4.) Mostly smooth, sometimes 

 hairy ; leaves pinnate with 3-15-leaflets, ar lyrate-pinuatifid ; leaflets 

 of the lower leaves rounded, angled or toothed ; of the upper, oblong 

 or linear, often entire; petals twice as long as the calyx (white); the 

 narrow pods and slender pedicles upright : style shorter than the 

 width of the pod. 



In woods, in districts of Waimea and Kona, Hawaii. (Probably introduced) . An almost 

 world wide plant. 



2. LEPIDIUM Linn. 

 Pouch roundish, much flattened contrary to the narrow partition, 

 and notched at the apex ; the valves narrow, boat-shaped and keeled. 

 Seeds one in each cell, pendulous. Seeds usually with the radicle
