Characteristics (Table 29, Figure 24) Plant: semi upright aromatic shrub, size medium to tall. Stem: upright, pubescent. Leaf: opposite, decussate, size long (mean 65.9mm), width narrow (mean 4.9mm), shape linear, mostly straight, margin entire, recurved, acute apex, base sessile, leaf colour green RHS 78B, pubescence strong, aromatic.

Origin and Breeding Open Pollination followed by seedling selection: ‘Willowbridge Wings’ arose as the result of a single cycle of seedling selection from open pollinated ‘Willowbridge White’ A at applicant’s property in New Zealand. Selection criteria: plant form, growth habit and flower colour. Propagation: vegetative through at least 5 generations. Breeder: W R and L C Young, Willowbridge Perennials, Tuakau, New Zealand. Choice of Comparators ‘Willowbridge White’ A was chosen because it is the seed parent and is considered to be similar to ‘Willowbridge Wings’. ‘Marshwood’ A was chosen because it is suspected as a pollen source. Comparative Trial Comparator: ‘Willowbridge White’ A , ‘Marshwood’ A . Location: Tynong North, VIC, winterspring 1999. Conditions: trial conducted in an open field, plants propagated from cutting, rooted cuttings planted into 140mm pots filed with soilless potting mix (pine bark base), nutrition maintained with slow release fertilisers, pest and disease treatments applied as required. Trial design: ten pots of each variety arranged in a completely randomised design. Measurements: from thirty plants at random. One sample per plant.

Applicant: Brent E Wilson and A Rex Wilson, Logan Reserve, QLD. Characteristics (Table 30, Figure 22) Plant: erect, dense, compact, medium, evergreen perennial shrub. Stem: upright, narrow, internodes medium. Leaf: lanceolate, length small (mean 52.30mm), width medium (mean 17.63mm). Mature leaf colour RHS 147A, partially mature leaf colour RHS 146A, new foliage colour RHS 200B. Flower: sepal 4, petal 4, stamens numerous. (Note: all RHS colour chart numbers refer to 1995 edition). Origin and Breeding Open Pollination followed by seedling selection: seeds were collected from open pollinated common form of Syzygium australe growing in applicant’s property in Logan Reserve, QLD. Seeds were germinated and several seedlings were raised for evaluation. One seedling was selected from the batch for its dense compact growth habit and dark coloured leaves. This selection now known as ‘Elegance’, was vegetative propagated through seven generations to confirm its uniformity and stability. Selection criteria: compact growth habit, dark colour of foliage. Propagation: vegetatively through cuttings. Breeder: Rex Wilson, Logan Reserve, QLD. Choice of Comparator ‘Aussie Boomer’ A was chosen as the comparator because of its similarity in the growth habit with the candidate variety. The Qualified Person considers it as the most similar variety of common knowledge. ‘Blaze’ A , ‘Bush Christmas’ and ‘Tiny Trev’ A were excluded because of their distinctly different vegetative form and leaves. The common form of Syzygium australe was also excluded because the candidate variety is easily distinguishable by its compact growth habit and dark coloured foliage. No other similar varieties of common knowledge have been identified. Comparative Trial Comparator: ‘Aussie Boomer’ A . Location: Kookaburra Park Nursery, Logan Reserve, QLD. Conditions: plants from cuttings raised in 140mm pots grown in full sun. Trial design: 30 plants of each variety arranged in 3 replicates in a completely randomised design. Measurements: from all trial plants. Prior Applications and Sales Nil. Description: David Hockings, Maleny, QLD.

Applicant: Hans. G. Storm, Svendborg, Denmark. Agent: Redlands Nursery Pty Ltd, Redland Bay, QLD. Characteristics (Table 31, Figure 10) Flower: diameter mean 8.27cm, no seams in corolla, colour upperside at anthesis deep pink (57C), underside main colour deep pink (57D), stripe deeper pink (57B), white stripe between the two. Flower bud: colour deep pink (57B), length mean 8.24cm, length unfused portion mean 3.09cm. (Note: all RHS colour chart numbers refer to 1966 edition) Origin and Breeding Spontaneous Mutation: originated as a spontaneous somatic mutation on Mandevilla (syn Dipladenia) sanderi ‘Rosea’ growing in applicant’s property at Svendborg, Denmark. The parent variety was characterised by deep red flowers and the sport was distinguished by bright lolly pink blooms. It was selected asexually through several generations to ensure uniformity and stability of the distinctive characteristics. Selection criteria: flower colour. Propagation: ‘Guinevere’ will be commercially propagated by vegetative cuttings. Breeder: Hans G. Storm, Svendborg, Denmark. Choice of Comparators ‘Pale Face’ A , ‘Wilma’s Choice’, ‘Rosea’, ‘Scarlet Pimpernel’ A , ‘Cinderella’ A and ‘Merlin’s Magic’ A were initially considered for the 47
