PHILODENDRON PLANT Filed March lO, 1969 Rh'. MSL/LEY United States Patent O 3 034 PHiLoDENhRoN PLANT Robert H. McColley, Orlando, Fla., assignor to Yoder Bros. Inc., Barberton, Ohio Filed Mar. 10, 1969, Ser. No. 805,911 Int. Cl. A0111 5/00 U.S. Cl. Plt.88 1 Claim My present invention comprises a new and distinct variety of philodendron plant, the result of crossing several unpatented and unnamed varieties of my own origination which I do not otherwise designate, but which were in turn bred and selected by me from previous crosses made during the course of an extensive program of hybridizing.

Actually the female parent of the instant yvariety was in turn bred from an unnamed seedling resulting from a cross between the two species, Phlodendron hastatum and Phlodendron erubescens. Y

The male parent as indicated was also bred and selected by me and it was in turn an unnamed seedling whose female parent was (Phlodendron hastatum Phlodendran erubascens) Philodendron wendlandii, and whose male parent was Phlodendron z'mbe. There are therefore four distinct philodendron species utilized in the hybridization of the instant new variety.

My present new variety is essentially the result of an extensive hybridizing program which has been carried on for many years in my greenhouses in Orlando, Fla., and has involved the selection of characteristics of certain parental varieties which I believe were valuable and which were in turn in most cases of my own origination developed from the various philodendron species known.

The result of the specific hybridization outlined in detail hereinbefore has been to produce the present new and distinct variety, to in turn provide for a fast rate of growth 'as indicated by the fact that under normal greenhouse conditions a young plant may be developed in three months from a tip cutting. While it requires six months to produce a mature plant from the saine type of cutting, this is in turn indicative of the relatively fast rate of growth provided by my new variety.

My new variety is vigorous, compact and non-branching and an average plant 0f ve leaves propagated from tip cuttings attains a height of y inches with a spread of to 18 inches. A tive-leaved plant propagated from single eye cuttings may attain a height of 8 inches with a spread of 9 to 12 inches.

My instant new variety is a foliage plant as is usually true of philodendrons, but it is distinctly different from both of its parents or any other philodendron presently known to me.

It may be contrasted with prior known varieties and particularly those which I have grown myself, by pointing out that in contrast to Burgundy, the instant new variety elongates at about half the rate, staying short longer with an overall smaller leaf.

My instant new variety produces longer leaves with shorter petioles in contrast to Burgundy, in which the leaves are too large and too open.

ICC

Better plant volume is provided by my new variety among other things, but one of the important improvementsl of my instant new variety is its very resistance to bacterial soft rot and good resistance to shotgun fungus.

My new variety has been asexually reproduced by tip cuttings in the vicinity of Orlando, Fla., and has also been asexually reproduced by single eye cuttings in the same vicinity, observations having been made of the leaf, stern and petiole color characteristics under daylight illumination under clear vinyl of not more than 30% light reduction (Bailey, L. H. and Bail-ey, E. Z. Hortus Second 1949).

My new variety has been found to retain its distinctive characteristics through successive asexual reproductions.

The accompanying drawing forming a part hereof shows a typical plant of my new variety, the colors being as nearly representative of the actual colors of the plant as is possible in such an illustration.

The color references are made based upon comparison with the Munsell Book of Color, 1963 edition.
