Jacques Amyot Damask Perpetual. Varangot, 1844. [Author cites information from different sources and tells us Jacques Amyot was the Bishop of Auxerre and a translator, 1513-1593.]
"Canes reddish at first, later changing to dark green, with occasional small thorns, canes very noticeable due to the young buds, which are violet or reddish. Leaves composed of 5 leaflets, sometimes 7, oval-pointed, beautiful dark green, finely and regularly dentate; stem big and thick, long, reddish, covered with glandular bristles which are close-set; sepals elongate and foliaceous. Flower very full, from 7-9 cm across to ca. 4 inches], beautiful purplish red, double; the central petals are for the most part split in bud fendus en bouton]. This flower resembles a beautiful purple Ranunculus." [Journal d'Horticulture Pratque et de Jardinage, 1845/279]

The situation with 'Jacques Amyot' continues very confused; there are persistent reports of a Noisette 'Jacques Amyot', with attribution "Varangot, 1850" - though we have been unable to track down positive evidence of it. If the two are separated, then, the DP is red-purple, and the noisette is deep rose or lilac-pink.
