Applicant: Jan and Peter Iredell, Moggill, QLD. Characteristics (Table 10, Figure 16) Plant: growth habit spreading, size small-medium, Stem: degree of hairiness absent or low, thorns present, size of thorns small, thickness of thorns thin-medium, shape of thorns concave. New growth: presence of anthocyanin absent. Leaf: size medium, length of blade (mean) 71.92 mm, width of blade (mean) 52.26 mm, length of petiole (mean) 21.19 mm, shape broad ovate, shape of apex acuminate, shape of base cuneate, undulation of margin medium, shape of cross-section concave, curvature of longitudinal axis incurved, glossiness of upper side weak, presence of variegation present, type of variegation marginal, degree of variegation medium. Leaf colour: number of colours three or more, primary (most prevalent or obvious) colour RHS 147B, secondary colour RHS 160A, tertiary colour RHS 191B, border between colours clearly defined. Bract: size medium, degree of reflex straight or low, width broad, shape of apex acute, partly expanded number of colours one, primary colour RHS 157B, fully expanded: number of colours two, primary colour RHS N74B, secondary colour RHS 155C. Flower: present, diameter small, predominant colour of visible petals (perianth) cream, predominant colour of floral tube white, size of floral tube small, shape of floral tube slender, emergence of stamens absent. (Note: all RHS colour chart numbers refer to 2001 edition.) Origin and Breeding Spontaneous mutation: originated as a bud-sport on Bougainvillea ‘Raspberry Ice’ at applicant’s property during 1990. The sport was characterised by variegated leaves, bicoloured bracts and compact growth habit. The mutated shoot was isolated and propagated vegetatively through six generations to confirm the uniformity and stability of the selection. Selection criteria: compact growth habit, variegated foliage and bract colour. Propagation: by cuttings. Breeder: Jan Iredell, Moggill, QLD. Choice of Comparators Grouping characteristics used in identifying the most similar varieties of common knowledge were – Bract colour, and variegation of leaves. On the basis of these grouping characteristics ‘Raspberry Ice’, ‘Orange Stripe’ and ‘Majik’ A ’ were selected as comparators. ‘Raspberry Ice’ is also the original parental variety. Comparative Trial Location: Moggill, Qld. Dec 2000-May 2002 Conditions: plants raised in soilless potting media in 200mm pots, fertilised with slow release Osmocote® added at 5g/litre, grown under greenhouse film. Normal cultural practices except pruning carried out during the trial. Trial design: 6 plants each variety randomly placed. Measurements: taken from all trial plants. Prior Applications and Sales Nil. Description: Jan Iredell, Moggill, QLD.

Applicant Jan and Peter Iredell, Moggill, QLD. Characteristics (Table 11, Figure 17) Plant: growth habit spreading, size small-medium. Stem: degree of hairiness absent or low, thorns present, size of thorns small-medium, thickness of thorns medium, shape of thorns concave. New growth: presence of anthocyanin absent. Leaf: size smallmedium, length of blade (mean) 74.38mm, width of blade (mean) 40.91mm, length of petiole (mean) 15.46mm, shape elliptic, shape of apex acuminate, shape of base cuneate, undulation of the margin medium, shape of cross-section concave, curvature of longitudinal axis recurved, glossiness of upper side strong, presence of variegation present, type of variegation central, degree of variegation very low. Leaf colour: number of colours three or more, primary colour (the most prevalent or obvious) RHS 139A, secondary colour RHS 146A, tertiary colour RHS 160C, border between colours not clearly defined. Bract: size medium, degree of reflex high, width narrow, shape of apex acute, partly expanded number of colours one, colour RHS 150D, fully expanded number of colours one, colour RHS 155C. Flower: present, diameter small, predominant colour of visible petals (perianth) yellow, predominant colour of floral tube green, size of floral tube medium, shape of floral tube slightly swollen, emergence of stamens present. (Note: all RHS colour chart numbers refer to 2001 edition.) Origin and Breeding Spontaneous mutation: originated as a bud-sport on Bougainvillea ‘Panda’ at applicant’s property. The sport was characterised by variegated glossy leaves and a higher number of flowers, whereas the parental variety produces fewer flowers and has different variegation. The mutated shoot was isolated and propagated vegetatively through several generations to confirm the uniformity and stability of the selection. Selection criteria: glossy variegated foliage and flower number. Propagation: by cuttings. Breeder: Jan Iredell, Moggill, QLD. Choice of Comparators Grouping characteristics used in identifying the most similar varieties of common knowledge were – leaf shape and glossiness, presence of variegation and bract colour. On the basis of these grouping characteristics ‘Panda’, ‘Nonya’ A and ‘White Cascade’ were selected as comparators. ‘Panda’ is also the original parental variety. Comparative Trial Location: 50 Sugars Rd Moggill, QLD. Apr 2001-May 2002. Conditions: plants raised in soilless potting media in 200mm pots, fertilised with slow release Osmocote® added at 5g/litre, grown under greenhouse film. Normal cultural practices except pruning carried out during the trial. Trial design: 3 plants of each arranged randomly. Measurements: taken from all plants. Prior Applications and Sales Nil.
