Dicenlra. FUMAKIACE^. 93 



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

 Stamens two sets of three each, the phalanxes opposite the outer and larger petals : 

 middle anther of each 2-celled, lateral ones 1 -celled. Ovary 1-celled with two 

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

 two valves falling away from the nerviform placentae, as in most of the Papave- 

 racece. Stigma often 2-horned or 2-lobed on each side alternate with the placentae. 

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

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

 fruit. 



* Corolla bigibbous or two-spurred ; the two outer and larger (lateral) petals similar : 

 capsule siliquiform, several-seeded. 



1. ADLUMIA. Petals permanently united into a subcordate spongy-cellular or marcescent- 

 persistent corolla, enclosing tlie slender ripe capsule. Stamens liigli-monadelphous, at 

 summit diadelphous. Seeds crestless. 



2. DICENTRA. Petals less or slightly united into a 2-spurred or merely 2-gibbous necta- 

 riferous corolla. Stamens diadelphous ; the filaments of each phalanx partly or lightly 

 cohering, at least about the midtUe, or distinct. Seeds mostly crested. Pedicels 2-bracteolate. 



* * Corolla with only one of the outer petals spurred or gibbous and nectariferous, by 

 torsion becoming posterior, all erect and convenient up to the shut tips of the outer. A 

 nectariferous spur-like process from the base of the filaments on that side projects into 

 the petal-spur. 



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

 Style mostly persistent. Corolla deciduous. 



FUMARIA. Flower of Corijdalis 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 di.ssected foliage, and dense 

 racemes of small flesh-colored flowers with dark crimson tips, — a weed in and about gardens 

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