Fumariaceae, DC. Si/st. 2. 105. (18211; Prodr. 1. 125. (1824) ; Endl. Gen. p. 858; Meisner, p. 8. Diagnosis.—Berheral Exogens, ^oith irregular unsymmetrical fovjers^ parietal placentee,and stamens opposite the plants, with brittle stems and a watery juice. Leaves usually alternate,multifid, often with tendrils. Flowers purple, white, or yellow. Sepals 2, 13 2 5 Fig. CCCIY. Petals 4, cruciate, very irregular. Stamens 4, distinct, hypogynous, or 6, in 2 parcels,opposite the outer petals, very seldom all separate; anthers membranous, the outer ofeach parcel 1-celled, the middle one 2-celled. Ovary free, I-celled ; o^Tiles horizontal,amphitropal; style filiform ; stigma with two or more points. Fiuit various; either anindehiscent 1- or 2-seeded nut, or a 2-valved or succulent indehiscent polyspcrmous horizontal, shining, crested. Albumen fleshy. Embryo minute, out of the axis ;in the indehiscent finiit straight ; in those which dehisce somewhat curved. Any one who compares Fumaria \\\\h. Epimedium, or Aceranthus with Hjpecoum,will see their very near resemblance, and thus will be led to admit, what at fiist sightseems inadmissible, the affinity of Fumeworts and Berberids.
