Thalie la Gentille Descemet (?), before 1811.
Synonyms: Thalie (according to Prévost, 1824).
Habit: Upright, strong branches; crooked and pointed prickles; can get taller than 2 m. Foliage: light, elliptical leaflets; quite large, edged with a fine red border when young. Bloom: medium size, rarely solitary, more often in clusters of 3 or 4, sometimes 6 or 7, very double, cupped, quartered, reddish central eye, passing to light green. Colour: deep carmine-pink, veined, lighter on the outer petals. Fragrance: very strong.

In 1811 Guerrapain described 'Thalie la gentille' as follows: "This rose resembles its sister and companion 'Euphrosine' in form and twisting; but it is smaller, of a more soft red; it is as fragrant, blooms at the same period. One finds the same similarities in the wood and the foliage."
In his catalogue of 1829, Prévost calls this rose 'Thalie', classes it as a damask and notes that it is found in the nursery of Vibert. The classification as a Damask is easily understandable, as 'Thalie la gentille' is probably a hybrid of gallica and damask (as Le Rouge also points out in 1819).
The fact that Guerrapain considers 'Thalie la gentille' and 'Euphrosine l'élégante' as sisters and companions lets us think that the former is probably an introduction of Descement as the second. It is from Descemet that Vibert, his successor, has quite naturally obtained 'Thalie la gentille'. Their similarity has likley led Descemet to give both the names of two of the "Three Graces"; these names from Antiquity are quite in his manner. Very logically, Gravereaux has estimated that 'Thalie la gentille' was found at Malmaison during the time of Joséphine: it was recently re-established there....

Thalie La Gentille.
Cette Rose ressemble pour la forme et la tournure, à sa sœur ou compane Euphrosine; mais elle est plus petite, d'un rouge plus tendre; elle est aussi odorante, fleurit à la même époque.
On trouve les mêmes ressemblances dans le bois et les feuilles.
Ce sont deux jolies variétés, ainsi que la suivante, Aglaia.
