1 Claim. (Cl. 47-60) The present invention relates to a new and distinct variety of ornamental vine of the Bignoniaceae family, originated by crossing Distictis lacciflora and a similar vine identified as Phaedranthus buccinatorius.

Its particular claim to novelty resides in the entirely new shade of color for these flowers of the Bignoniaceae family, this color being according to Ridgways color standards and nomenclature, near Purple (true), Plate Xi, veined near Aster Purple, Plate XII, with th Purple changing abruptly but irregularly at the point where the base of the limb lobes joins inside of the corolla tube to near Lemon Chrome, Plate IV, on the inside surfac of the limb lobe. It will be noted that in this respect this characteristic differs from Phaedranthus buccinatorius which is distinctly colored in the red tones on the inner surface of the limb lobe.

In addition to these color features illustrated in the accompanying drawing as nearly true as possible, the new variety is distinctive as to size and shape of the flower in comparison with other similar varieties grown under comparable conditions, resembling more nearly that of Phaedranthus buccinatorius than is common in the parent Distictis laxiflora. Sometimes it approaches nearly six inches in length, whereas in the parent Dististis laxiflora, the tubular flowers are seldom more than three and a half inches in length.

This new variety, likewise, compares in habit of growth and vigor more closely to that of Phaedranthus buccinatorius than to its other parent.

Also, more similar to Phaedranthus buccinatorz'us is the flowering habit which is intermittent throughout the year in mild climates, such as Southern California, in the vicinity of Santa Monica. The foliage of this new variety is very glossy when mature, and, therefore, with these particular features in mind, it is claimed that this seedling of Distictis lazciflora is a distinctly new variety, not only because of its wide difference from its seed parent, but from other known members of the Bignoniacea family as well.

The following is a detailed description of this new ornamental vine, the color terminology employed therein being in accord with Ridgways Color Standard:

Type: Half-tender; tall; woody; vine; monoecious; gamopetalous; seedling; outdoor plant for "garden decoration. Class: Seedling.

Seed parent.-Distictis laaciflora. Pollen parent.-Phaedranthus buccmatorius. Propagation: The distinguishing characteristics have been found to come true to form by the following method of reproduction which is the only one tried up to this time: by cuttings.

Flower Locality where grown: First grown at Santa Monica, California, and then moved to Mandeville Canyon, West Los Angeles, California.

Flowers borne: Two, four to severalto stem; most- 1y terminal on lateral branches, mostly erect, panicles or racemes, with strong pedicels; with both short and long peduncles arranged in pairs of opposite flowers; each successive pair arranged in position on stem above at right angles to its predecessor (decussate); sometimes this arrangement is compound but always dichotomous.

Quantity of bloom: Free; outdoors.

Continuity: Intermittent to nearly continuous in mild climates, such as southern California.

Fragrance: None (seed parent vanilla scented).

Pedicel: Medium heavy; to 2" long, covered with pubescence and straight with distinct abscission layer soon formed between upper end and bending stalk of receptacle, allowing old flowers to drop off at end of usefulness.

Col0r.-Near Courge Green, Plate XVIII, on shaded side, near Olive Green, Plate IV, on sunny side.

Flower:

Size-When fully open, large; 2%" to 3%" in diameter.

This description of a newly opened flower was made from a plant grown outdoors in September, 1941, at Rivers Road, West Los Angeles, California:

Color .-Outside surface-near Bishops Purple, Plate XXXVII, changing abruptly at point where base of limb lobe joins outside of corolla tube, Corolla tube vari-colored near Purplish Lilac, Plate XXXVII, on the upper side (side exposed to most sun), blending gradually toward under side to near Primrose Yellow, Plate XXX. Upper side of tube lightly penciled with also parchanges abruptly at extreme base to between Chalcedony Yellow, Plate XVII, and Chartreuse Yellow, Plate XXXI} Inside surface-limb lobes near Purple; (true),- Plate XI, veined near Aster Purple-, Plate XII. Purple changes abruptly but irregularly at point where base of limb lobes join inside of corolla tube, to near Lemon Chrome, Plate IV.

Two-day flower.-- Inside surface--limb lob near Pansy Violet, Plate XI, veined with Purple (true), Plate XI, irregularly, at

,. pointwhere base of limb lobe joins inside gof corolla tube, to near Lemon Chrome,

Plate IV. Outside surfacepetals between V -Ag'eratum Violet, Plate XXXVII, and 'Ar- 1 :gyle Purple, Plate XXXVII, blending grad- ,ually, at point where base of petal joins 1 corolla tube, to near Purplish Lilac, Plate XXXVII, on upper side of corolla tube,

and to' between Pale Lobelia Violet, Plate 'XXXVII, and White on under side of corolla tube. Flower does not pull out of calyx tube second day.

This description was made from a plant that was open for three days outdoors in the month of" September,;1941,, at Rivers Road, West Los Angeles, California: I

Colon-Outside petal, outside surface-petal I f between Chinese Violet, Plate XXV, and Lilac, Plate XXV, blending gradually at point Where base of petal joints corolla tube, to near Purplish Lilac, Plate XXXVII, with some nearly parallel pencilings running from base to near the top of corolla tubes (more prominent near base) of near Argyle Purple, Plate XXXVII, on the upper side of corolla tube. Under side of corolla tube changes abruptly to between Pale Lilac, Plate XXXVII, and White. Point of attachment between Napthalene Yellow, Plate XVI, and Barium Yellow, Plate XVI, all around base of tube at point of attachment. (This color is not. seen until corolla tube is slipped or pulled out of the monosepalous calyx tube, and the color dividing line is conspicuous by reason of the distinct break in color). Inside surfacenear Argyle Purple, Plate XXXVII, blend- ,ing toward the border of each petal to near I Ageratum Violet, Plate XXXVII. Toward lower half of petal color changes abruptly to near Liseran Purple, Plate XXVI, and Rose Purple, Plate XXVI, at point where base of petal joins inside of corolla tube which in turn changes abruptly and irregularly; at top end of corolla tube tovbetween.
