Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The accompanying drawings are color photographs of the new blueberry plant NS 15-13 during the third year of growth under the ecological conditions prevailing at the breeder's property, which is located at Yanchep Springs in Yanchep, Western Australia.

[0016] FIG. 1 is a color photograph, which shows fruit, blooms, leaves, and a portion of a vegetative stem of the new blueberry plant NS 15-13, the fruit being sufficiently mature for harvesting and shipment. This photograph also depicts the large fruit size and the color of the ripe fruit, two leaves showing the sizes and the upper and under side colorations thereof, two blooms at different stages of maturation, and additional leaves on the stem at different stages of maturation.

[0017] FIG. 2 is a color photograph, which shows the new blueberry plant NS 15-13. This photograph depicts a mature bush with ripe and unripe fruits, the large fruit size, and the upright growth habit of the bush. The ripe fruit is sufficiently mature for harvesting and shipment.

[0018] The colors in these photographs are as nearly true as is reasonably possible in a color representation of this type. Due to variations in color printers and/or chemical development, processing and printing, the colors of the plant parts depicted in these photographs may, or may not, be accurate when compared to the actual specimen. For this reason, color references are made to the color plates (Royal Horticultural Society Colour Chart, Sixth Edition, hereinafter, R.H.S.) and descriptions provided.
