stigma, which is flattened contrary to and has lobes alternate with the placentju. 

 Stamens two sets of three each, the phalanxes opposite the outer and lar^jjer pilals : 

 middle anther of each 2-eelled, lateral ones l<'elled. Ovary 1-celled with two 

 parietal several-ovuled placentae ; in fruit usually a siliquiform capsule, with the 

 two valves falling away from the nerviform' placentju, as in most of the Pajxne- 

 racem. Stigma often 2-horned or 2-lobed on each side alternate with the placenta'. 

 Ovules amphitropous or anatropous. Seeds with minute embryo in Heshy albu- 

 men. Fumaria has a one-ovuled ovary, becoming an indeliiscent nuculaceous 

 fruit.

 ciijisiile sili(|iiiforin, several-seeded. 



1. ADLUMIA. Petals permanently united into a snlu-ordaie siioncjy-cellular or ni.ircesecnt- 

 persistent corolla, enclosing the slender ripe capsule Stamens liigii-monadelplious, at 

 summit diadelphous. Seeds crestless. 



2. DICENTRA. Petals less or sliglitly uiiited into a 2-spurred or merely 2-;,'il.l)ons n«'(ta- 

 rifenius cnrnlla. Stamens diadeljjlious ; tlie filaments of eacii jtlialaiix partly or li;,'litly 

 cohering, at least abt)ut the middle, or distinct. Seeds mostly crested. Peilicels 2-ljracteolate. 



* * Corolla with only one of the outer petals spurred or gil)l)ous and nectariferous, \>\ 

 torsion becoming posterior, all erect anil convenient U]) to the shut ti|»s of the outer. A 

 nectariferous spur-like process from tlie base of the filaments on that si(k' projects into 

 the petal-spur. 



3. CORYDALIS. Capsule few-many-seeded. Seeds with a concave arilliform cre.st. 

 Style mostly jiersistent. Corolla deciduous. 



FUMAKIA. Flower of Cori/dalis on a small scale. Style deciduous. Ovary uni-ovulate. 

 Fruit a one-seeded nutlet. Old World genus. 



F. OFFICINALIS, L. A widely branched low annual, with finely dissected foliage, and ilonso

 and on dunghills, — can hardly be said to be naturalized in this country.
