it should be understood and is i am sure , that the photographic reproductions are as nearly representative of the actual plants as is possible to make the same by this type of illustration and in my judgment are representative of such disclosures and accurate as the eye can determine . in order to further describe the new dieffenbachia plant , based on observations made in the greenhouse near apopka , fla ., where the plant was propagated , i believe the following color references as measured against the royal horticultural society colour chart are as nearly accurate as is possible to make the same and colors are approximate as color depends on horticultural practices such as light level , fertilization rate , and leaf age among others . overall size and growth habit : in a 15 cm standard pot after approximately 6 months of growth under appropriate conditions from a liner obtained from tissue culture , 61101 will be approximately 65 cm from the soil surface to the tips of the uppermost leaves when held upright . at this stage of growth leaves average approximately 36 cm in length and 16 cm in width . plants of this size average approximately 3 . 5 basal shoots . all subsequent measurements are based on the above parameters . the ultimate size of 61101 , if planted in a sufficiently large container and grown under appropriate conditions , has not been determined . stems : the stem color is not generally visible due to the clasping nature of the petiole wings . removal of the petiole exposes an area that is made up of two colored areas that are irregular in shape and consists of a lighter area that is rhs 147 - d and a darker area that is rhs 144 - a . the axillary bud that is also exposed upon removal of the petiole is rhs 147 - b . a small area of the stem is visible without removal of the petiole and is rhs 147 - a . petioles : the petiole consists of two colored areas that blend near the center . the outside edge of the petiole is rhs 146 - b while the center of the petiole is rhs 146 - d . leaves : the leaf midrib is thick and tapers toward the apex . it protrudes prominently from the abaxial side of the leaf and is rhs 155 - c . the general background color in the central half of the leaf blade is rhs 191 - b while the outer portion of the leaf is 191 - a . this area darkens to rhs 189 - c in older leaves . the primary leaf veins are sunken into the adaxial side and stand out from the abaxial side of the leaf blade . the color of the primary veins is the same as that of the adjacent leaf blade . in summary it may be stated that the variegation is disclosed as comprising many small irregular islands rhs 155 - b / c scattered throughout the leaf blade . the color of the islands extends through the leaf and is visible when viewed from the other side . there are also some darker islands scattered throughout the leaves that are rhs 191 - c . the top surfaces of the leaves are predominately silvery - grey , and are highlighted by a white midrib . a pattern of blotches which is generally less dense with progressive distance from the midrib is expressed . blotches close to the midrib are white rhs 155 - c , and those most distant to the midrib may be partially or wholly light green , near rhs 191 - c . the margins of the lamina are of a darker shade of green , rhs 191 - b , than the light green spots , but an even darker green near rhs 147 - a , may occur as small spots near the margin and this darkest green may constitute a non - uniform and interrupted marginal variegation , and the vein portions which lie over the predominate green of the top surfaces . these are usually less prominent than the white islands . the backsides of the leaves are generally rhs 147 - a and the midribs are rhs 157 b / c . the white islands are also visible on this side and are again rhs 155 - c . there are also present some irregularly shaped light green islands that are rhs 144 - a . axillary shoots : mature plants may produce up to 4 basal shoots per plant . inflorescences : flowers were not present on plants of the age examined , and are of no ornamental value in dieffenbachia . i belive the foregoing description will enable a person in the art to identify my particular plant as being distinctive from the others and without necessity to use additional botanical terms , except where they obviously are appropriate . the plant ` 61101 ` grows into a specimen having a single main stem having plural closely adjacent secondary stems , which are basal in source , forming a dense , short mass of high coloration in attractive green tones . the canopy of this plant is unusually attractive in having color splashes which appear to be applied rather than naturally formed ; giving a first impression of a synthetic rather than live plant . this genotype offers distinct and unusual characteristics in patterns of coordinated colors , uniformity of leaf sizes and closeness in leaf spacing which give the plant a highly desirable balance and richness of form in most growth stages , and constitutes a resource for these traits . in so doing , ` 61101 ` greatly expands the range of expression in available dieffenbachia plants .
there is disclosed a representative plant of dieffenbachia designated 61101 , which is one displaying a variety of variegated areas on each leaf , none uniform , which are enclosed by a green border and thus become distinctive in and of themselves , the variegations being repeated in all the leaves and without uniformity .
