1 Claim. r (C1. 47-61) This invention aomprises a new and distinct variety 0f rosa plant ofthe hybrid taa class, the novel and distinguishing characteristics cf which are particularly the unique flower color, the high-cantered flower form and size, the contrasting dark color of the foliaga, and the bushy upright growth o1: the plant.

This naw rosa plant rasulted from pollinating the rosa variety Sutters Gald (Plant Patent N0. 885) with the pollan cf an unnamad variety which I had previously originated by crossing the variety Mma. Henri Guillot (Plant Patent N0. 337) with the variety PD N0. 5023- 23 (unpatantad and not in commerce). One 0f my objacts in originating the prasent rosa plant was t0 produce'a rosa 01 a uniqua color. The pollinating t00k placa in 1951at Scppoose, Oregon, the first flowar was producedin 1952, and thaplant was 'first aisaxually reproducad at Scappoose, Oreg0n, in 1952, by bud-grafting. Since than the variety has retained it's'distinguishing charactaristics through succeed ing propagations by bud-graft- The flower color of the naw variety is lass yellow than that 0f the seed parant (Sutter Gold) and the plant is lass tall in habit. V

- In comparison with the prallen parent (Mma. Henri Guillot crossed with PD 5023-23) the new variety is rn0ra yellow in flower color, has more patal's, is shorter and mora compact in plant habit, and somewhat lass vigorous in growth and lass resistant to disease.

The new variety is somewhat similar in color and in general habit t0 the variety Mojave (Plant Patent N0. 1,176) but the flower color 0f the new variety is more yellow and lass red, particularly at the base 015 the petals (outer surfaca); the flowar 'col0r does not fade as quickly and remains more intensa and lass pale insenascenca than that cf the Mojave; also the flower generally has more petals and the plant has more large th0rns and is slightly more vigorous in growth than the Mojava.

The accompanying illustration shows the plant in color with separated blooms in different stages 0f development. A detailed descripti on follows in which the following standard rafarences f01' color are cited:

(l) Wilson, R. F.; Royal Horticultural Society Col0ur Chart, England, 1940.

(2) Ridgway, R.; Color Standards and C0l0r Nomenclature, Washington, D.C. 1912.

(3) Nickerson C0101 Fan, Munsall Color C0., Baltimore, 1957. 7

Flowers The flowars are borne singly 011 long stams, 0r frequently in cymas 0f threa t0 sevan flowars, 0n medium stems.

The plant blooms abundantly outdoors and blooms almost continuously outdoors during the growing saason.

The flowars have a light fruity fragrance.

Longevity: Plant outdoors in September, 5 days; cut flowars from outdoor plant in September, 3 days. Patals drop cleanly.

Outside petal.-Outer surfacabasal fan near Canary Yellow (Wilson 2/1, p. 2, t0 2/2, p. 2) extending upward ab0ut /athe langth of the petal, merging irragularly with various shadas and tints of red, fr0m near Indian Orange (Wilson, 713, p. t0 near Dutch Vermilion (Wilson, 717, p. 156), sometirnes with areas flushad as deep red as Turkey Rad (Wilson, 721, p. 94). The main .veins 0f the petal sh0w clearly, baing darker and more red (i.e.-Turkay Rad (Wilson 721) than the surrounding tissua.

Flowar color (0f flowars three days after opaning in September 1959, at Scappoose, Oregon): General color efiect (face on)near Azalaa Fink (Wilson, 618, p. 74), sometimes more blue, i.e. Porcalain Rosa (Wilson 620, p. 147) with yellow ovartones.

Intermediate petal.-Oter surfacabasal fan near Canary Yellow (Wilson, 2/1, p. 2) extending upward or mora than the length cf the petal,

Size and form of open flower:

Size.Large (for exarnple, 13 cm. in diameter).

Form.I-Iigh-centered, rernaining so well into maturity when a gradual flattening occurs. The petals at first are slightly but firmly cupped inwardly, becorning flatter at maturity, and slightly rolled outwardly at apex. The petals (petaloids) of the inn'ermost row of petals tend to be irregular and rough in outline.

Pelalage.Double 28 35 petals.

Further flower details:

Petals.-Substancemedium thick, crisp. Texture: Inner surfacesatiny; unter surface-satiny. Shape: Outside petal-broadly obovate (i.e., 6 cm. Wide x 6.5 cm. long). Apical margin irregular. Intermediate petal-obovate (i.e., cm. wide x 6.2 cm. long). Apical margin irregular. Inside petal-obovate (i.e., 4.5 cm. wide x 6.0 cm. long). Apical margin irregular. The innermost row is often constituted of very irregular petaloids.

SepaIs.-Sizemediurn (i.e., 1.0 x 4.2 cm., including terminal foliaceous appendages). Shape spear shaped; curled back to peduncle. Foliaceous appendages typically present, both lateral and terminal. Color: Outer surface-no close match. Between Scheeles Green (Ridgway, 33, GYG. i, Plate VI) and Peacock Green (Rgway, 35, GREEN. i, Plate VI) irregularly flushed reddish. Inner surface-pubescent. Near Corydalis Green (Ridgway, 29", GG -Y. d, Plate XLI). Irregularly flushed reddish.

Flower bud:

Peduncle.-Mediurn length (i.e., 6 cm.); medium caliber (3-4 mm.); erect. Color near Scheeles Green (Wilson, 860/2, p. 175) usually with slight reddish flush on one side. Few glandular cilia, several very small reddish thorns.

Before calyx breaks.Size-mediurn 1arge (i.e., 1.9 cm. x 3.5 cm., including calyx-tube but excluding terminal foliaceous appendages). Formrnedium-long pointed, with ordinary calyx-tube; with foliaceous appendages on one or both lateral margins of most sepals, but usually with none on two of the five sepals, with moderately-incised terminal foliaceous appendages extending beyond the tip of the bud, usually ca. /3 the length of the bud. Colornear Scheeles Green (Wilson, 860, p. 175

As calyx breaks.-Color near Orange Rufous (Ridgway, II Orange i, Plate II) irregularly flushed near Blood Red (Wilson, 820/3, p. 166).

As first petal opens.Size-medium large (i.e., 2.5 x 4.0 cm). Forrn-long pointed. Color: Guter surface-near Mandarin Red (Wilson, 17, p. 17) flushed irregularly upward from base with near Lemon Yellow (Wilson, 4, p. 4). Veins strengly marked and petal irregularly flushed with Orient Red (Wilson, 819, p. 165). Inner surface brighter than Orient Red (Wilson, 819, p. 165). Base Lernen Yellow (Wilson, 4, p. 4).

Opening habit.-Opens very well.

Plant foliage:

Leaf.-Compound 5 to 7 leaflets, usual1y S; moderately abundant.

Leaflets.-Sizelarge (i.e., 4.2 x 7.5 cm.). Substance-medium thick; hard. Texture-glossy.

Shapeovate; with apex acute, base rounded; margin singly or irregularly serrate. Color: Matureupper surface-no good match; related to Dark Dull Yellow-Green (Ridgway, 31", Y- G. m, Plate XXXII); under surface-between Asphodel Green (Ridgway 29", GGY., Plate XLI) and Pois Green (Ridgway, 29", GG-Y. i. Plate XLI). Youngupper surfaceno close match; possibly related to Fern Green (Wilson, 0862, p. 186) but much darkened by the presence of anthocyanin pigments; under surfaceno match; related to Mineral Red (Ridgway, 1, RED k, Plate XXVII), with green undertone. (The interplay here of red and green in a fairly translucent tissue makes comparison extremely diflicult.)

Rachis.Medium. Upper sidegroove narrow but not shallow. Margins of groove with several gland-tipped cilia, few prlckles. Under side quite smooth, With few relatively heavy thor ns-. In the immature rachis, the groove, and upper surfaces, are pubescent.

Main stems (0 current year's growth).-Dull graygreen. Thornsseveral; medium lang (i.e. 12 mm.); hooked slightly downward; with medium oval base (i.e. 5 mm. x 13 mm.); dark brown.

Branches (currently bearing senescent flowers). Dull gray-green. Thornsseveral to numerous; medium long (i.e., 11 mm.) hooked moderately downward; with medium oval base (i.e. 3 mm. x

10 mm.) light tan with reddish flush.

New shoots (in rapid growth).Green flushed red, near Garnet Brown (Wilson, 00918/ 1, p. 192). Thornsseveral; medium long (i.e., 10 mm.) hooked slightly downward; with medium oval base (i.e. 2 mm. x 9 mm).

Further plant characteristics: The plant is bushy, up-

right, medium tall (up to 4 feet or more), moderately branched, and grows freely.

Reproductive organs:

Red at base, yellow above. Anthers size medium (i.e., 1 x 4 mm.); color, orange. Pollen-abundant and viable.

Pistils.Numerous. Styles-contorted, slightly uneven in length. Caliber medium; length medium (i.e., 7 mm). Loosely bunched, free. Stigmaordinary; yellowish. Ovaries-several exposed above calyx-tube, surrounded by cottony tissue.

ReceptacIe.-Shapedepressed turbinate, near conical. Rim (disc) prominent. Size-small (i.e., 9 mm. high x 13 mm. in diameter). Surfacevery lightly pubescent. Color-near Scheele's Green (Ridgway, 33 GY-G. i, Plate VI).

Havlng thus disclosed my invention, I claim:
