NATURAL HISTORY OF PLANTS. 



ferous simple. Seeds (almost of Mattlriold) 1-seriate, much compressed 

 marginate. — Herbs, annual or perennial, glabrous; leaves entire or the 

 lower lyrate-pinnatifid ; cauline leaves sessile or occasionally amplexi- 

 caul ; flowers 1 in terminal racemes, bracteate or ebracteate 2 {North 

 America, especially the eastern parts''). 



7. Cardamine T. 4 — Sepals equal at base. Petals unguiculate. 

 Flowers and fruit otherwise nearly oiArabis ; siliqua elongated linear- 

 compressed ; valves flat, almost ribless separating elastically ; septum 

 hyaline ; style short or elongated ; apex stigmatiferous, more or less 

 enlarged, simple or 2-lobed ; replum obtuse {Dentaria) 5 or acute or 

 alate {Pteroneuron). 6 Seeds go, 1-seriate, somewhat compressed im- 

 marginate ; funicles occasionally enlarged {Pteroneuron, Dentaria) ; 

 embryo rather fleshy (occasionally coloured) ; cotyledons accumbent 

 or more rarely incumbent. 7 — Herbs, usually flaccid and glabrous ; 

 rhizome sometimes scaly or bulbiferous {Dentaria) ; leaves alternate, 

 more rarely opposite, or 3-4-verticillate {Dentaria), occasionally 

 pinnatisect ; flowers 8 in racemes, sometimes subcorymbose, ebracte- 

 ate, erect or nutant {All Temperate, cold and Alpine regions 9 ). 



8. Dryopetalum A. Gray. 10 — " Sepals suberect ; lateral subsaccate 

 at base. Petals unguiculate, 5-7-lobed. Stamens without teeth. 

 Siliqua 11 elongated, somewhat terete, many-seeded ; valves 3-ribbed 



1 Often handsome, sometimes pendulous, 

 purple, or more rarely white or yellow. 



2 Sections 2, according to Endl. : 1. Fitstrep- 

 tanthus ; calyx rather spreading; limb of petals 

 broad. — 2. Eiiclisia (Ntttt.) ; calyx closed ; limb 

 of petals narrow. The genus is very near Arabis.

 author, not 1-seriate, as in the other species.
