Plante anne caulibus elongatis ramosis diffusis vel scandentibus. Folia 
caulina, primordia longe petiolata, reliqua breviter petiolata vel subsessilia, 
foliolis plerisque longe petiolatis et segmentis secundariis vulgo petiolatis 
rarius decurrentibus irregulariter 2—4-pinnatisecta ; petioli ssepe cirrhosi. 
Inflorescentia pedicellis etiam fructiferis omnibus brevibus nee elongatis 
racemosa. Bracteæ pedicellos fructiferos sæpe subæquantes nunquam 
multototies breviores. Corolla unicalearata ; petalorum exteriorum margines 
apicem versus in statu juvenili parum explicati vel obsoleti ; petalum superius 
fere semi-cylindricum, calearatum, superne gibbum apicem attingentem 
format qui alas basin versus /n jugum rotundatum laterale productas sæpe 
atropurpureas habet ; petalum inferius angustum, plus minusve canaliculatum, 
haud. calearatum, inferne gibbum apicem attingentem marginibus patentibus 
vel erectis circumdatum efficit; petalorum interiorum nervus medius apice 
modice alatus est. Fructus monospermus, indehiscens, nuciformis, muticus 
rarius mucronatus vel apiculatus, apice per duas rimas que mesocarpium 
perforant bifoveolatus est ; exoearpium interdum lieve vel subleve interdum 
tubereulis in sicco videndis rugosum ; endocarpium sub stylo a mesocarpio 
disjunctum, in hemisphæræ formå depressum ; semen superne in crateris formd 
exeavatum, rugd longa infra mieropylam notatum. 
Annual plants, often climbing, with long stems and cauline leaves. 
Inflorescence racemose with short pedicels. Lower petal never spurred. 
Fruit, when dry, with apical pits. 
Although Hammar, in his monograph, gives a generic diagnosis of some 
length, a few criticisms are necessary, as well as some notes on the import- 
ance of the variations of the different organs in considering specific 
characters. In the first place, it is to be remembered that Fumitories, like 
some other weeds of cultivation, are very susceptible, especially in the
