2— ROSA HARDII Cels 
(R. CLINOPHYLLA x BERBERIFOLI A) 
Rosa Hardii Cels in Ann. de Flore et de Pomone , vol. iv. pp. 372, 373, fig. 
(1835-6). 
R. berberifolia x involucrata Paxton, Mag. Bot. vol. x. p. 195, t. (1843). — 
Deseglise in Bull. Soc. Boi . Belg. vol. xv. p. 232 (Cat. Rais. Ros. p. 63 [1877]) 
(1876). — Nicholson in Gard. Chron. n. ser. vol. xxiv. p. 468, fig. 10 1 (1885). 
A low erect bush, with slender, spreading, pubescent branches. Leaflets 5-7, 
oblanceolate, obtuse, f-i in. long, narrowed to the base, simply toothed, firm, glabrous 
on both surfaces ; petioles pubescent ; stipules narrow, adnate, gland-ciliated, with 
large, strongly toothed, free points. Flowers solitary ; peduncles short, naked or 
slightly aciculate. Calyx-tiibe globose, naked or slightly aciculate ; lobes simple, 
lanceolate, entire, not glandular on the back. Petals large, pale bright yellow, with 
a red-brown spot at the base. Styles villous, free, not protruded. 
This curious and beautiful Rose was described for the first time 
in 1836 by Cels in the Annales de Flore et de Pomone . After his 
description occurs the following : “ This interesting Rose, raised at the 
Luxembourg by our colleague M. Hardy, 1 from a cross between Rosa 
clinophylla and Rosa berberidifolia . It is of easy culture, and can with 
advantage replace Rosa persic folia in our gardens. The individual 
flower is larger in size and more symmetrical in form.” There is no 
mention of Rosa involucrata, as stated by Paxton in the Magazine of 
Botany , and by Deseglise and Nicholson. The Annales de Flore et 
de Pomone is a book so rare that Paxton may not have had access to 
it, and hence the misquotation. 
This Rose furnishes a manifest proof that hybrids may be made 
even between Roses of but little affinity. Rosa clinophylla Thory is an 
Indian and Chinese species which is classed in the group Bracteatae . 
Rosa berberifolia Pallas (Rosa persica Michx.) is, as we have seen 
(page 3), a species so different from all other Roses that several authors 
have thought it should be put into a distinct genus. Thus Dumortier 2 
made the genus Hulthemia, Linclley 3 Lowea, and Bunge 4 Rhodopsis. 
1 Hardy was Curator of the Luxembourg Gardens in Paris.
