Int. (:1. 301a 5/00 US. Cl. Plt.--18 1 Claim ABSTRACT OF THE DISCLOSURE A rose plant of the hybrid tea class, whose vegetative type corresponds to that of the variety 'Meichim 0257 F., more generally known in the trade as the rose Carina (U.S. Plant Pat. No. 2,378), but of a more even pink and less crimson color, with a pink color on the reverse side of the petals.

SUMMARY OF THE INVENTION The present invention is a variety of rose plant, of the hybrid tea class, whose vegetative type corresponds to that of the variety Meichim 0257 F., more generally known in the trade under the name Carina (U.S. Plant Pat. No. 2,378), but whose flowers, although being of the same form, are of a more even pink, less crimson, which, with the pink coloring of the reverse side of the petals, shows a less pronounced contrast than the one existing in the aforesaid variety.

Considering the interest which, in the horticultural industry, would not fail to arise by the disclosure of the different technical effect offered by the new variety as compared with the original variety, it was advisable to multiply this new variety on a large scale in order to check its behavior from the physical as well as from the biological point of view.

The results were conclusive and emphasized the importance of the disclosure of such a variety with a view to its industrial exploitation by the professional nurserymen as well as by the producers of cut flowers.

The characteristics and properties of this new variety, obtained as indicated above, are thoroughly transmissible by agamic means-also called asexual means, i.e. by any method of vegetative propagation, and in particular by grafting an eye, which will be called in the trade by the name Kamchim eye and which will be found on industrial plants as well as on the cut stems delivered subsequently in the trade.

DETAILED DESCRIPTION OF DISCLOSURE The following is a detailed description of my new variety in which the terminology of the colors corresponds to that or the Horticultural Colour Chart of the Royal Horticultural Society:

Class: Hybrid tea.

Plant:

Height.-'75 to 85 cms. in the open air; 1.20 m. to

' 1.40 111. under glass.

- Habit.straight, well branched.

Branches:

Color.-Young stems: Spinach Green (p. 187-0960/ 2) with a light Lettuce Green (p. 176-861/1) reflection close to the stipules. Mature wood: Spinach Green (p. 187-0960/ 1).

Prickles.Shape: straight. Size: medium. Quantity: fairly numerous and intermixed with acicules. Color: on young stems: slightly reddish, then greenish; on mature wood: light havana color (common terms).

Leaves:

Stipules.Adnate-generally narrow-with folded edges, more or less pectinate; the auricles are short and diverging.

Peti0le.-Obverse: the inside and the edges of the rib are more or less reddish brown in the young foliage, and normal green in the adult foliage. Reverse: light greengenerally with one or several small curved prickles.

Leaflets-Number: 3-5 and 7. Shape: elliptica1- acuminate. Teeth: single. Texture: leathery. General eflect: fairly wide foliage, of average density, and dull appearance. Color-young foliageupper surface: Spinach Green -p. 187 a little darker than 0960; under surface: Lavender Green p. 196-41 little rawer green than 000761/1; adult foliage upper surface: Spinach Green, p. 187-0960; under surface: Lavender Green, p. 196-000761/1 (It is to be noted that when growth starts, as also during the course of vegetation, the foliage of the young shoots is light green and reddish brown on the upper surface; reddish brown on the under surface. The outer skin of the tigelias is Lettuce Green (p. 176861/1.))

Inflorescence:

Number of flowers.-Generally one flower per stem.

Resistance to diseases.Blackspo t: very good. Mildew: very good. Powdery mildew: very good. Rust: very good.

I claim:

1. A new and distinct variety of rose plant of the hybrid tea class, characterized by the novelty of the plant, from the physical point of view, in thatthe plant, with Spinach Green mature wood, is of straight habit, the flower is double, Rose Neyron colored, its petals are very firm and folded up in a point when fully open, and from the biological point of view, the plant grows vigorously, blooms continuously, has a very good resistance to fungus diseases, its flowers are very long lasting, either on the plant or when cut, and their petals drop off cleanly.
