Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photograph in FIG. 1 illustrates in full color a typical plant of MonJaw grown outdoors in Dayton, Oreg. This plant is approximately 4 years old.

(2) FIG. 2 illustrates a close-up view of the foliage.

(3) The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

(4) In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe MonJaw plants grown outdoors in Dayton, Oreg. Unless noted as values taken from a mature plant, values are taken from a plant approximately 4 years old, grown in a 3 liter pot. The plant has been grafted onto a seedling of Pinus mugo. The specimen is approximately 4 years old, grown outdoors in Dayton, Oreg. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Measurements and numerical values represent averages of typical plant types. Botanical classification: Pinus mugo MonJaw. Age of the plant described: Values are taken from a 4-year-old specimen, unless noted as a mature tree measurement. Container size of the plant described: 3 gallon commercial container.
