is that it would allow the cultivation of these healthy fruit in the major subtropical citrus belt and/or the production of ornamental citrus plants, depending on the cultivar. The second benefit is that novel fruit, leaf, and flower colors could be

Abstract
During 1986, 15 cultivar names in unassigned woody genera were registered. Ten of these were dwarf spiraeas. During 1987, eight cultivar names in unassigned woody genera were registered. Herbarium specimens and photographs of the plants will be deposited in the U.S. National Arboretum Herbarium. Anyone who is involved in the origination or introduction of new cultivars of ornamental plants is urged to see that they are registered with a view toward nomenclatural stabilization. A list of International Registration Authorities is avalable from the American Association of Botanical Gardens and Arboreta (AABGA), P.O. Box 206, Swarthmore, PA 19801.

Due to the large area and the complex topography and climate. a great deal of wild ornamental plants are still hidden in the depth of forests and on the highland plateaus--places difficult to approach by man. In the Three N Regions only, there are 51 species of Rhododendron, 27 of Lilium, 83 of Rosa, 30 of Iris, 40 of Clematis, etc., yet to be explored and utilized. Aiming at this, we made extensive introduction of plants in general and intensive introduction of certain families and genera in particular, with good results. At present we have in our living collection 12 species of Clematis, 24 of Rosa, 13 of Lilium, 10 of Iris, 8 of Tulip, 6 of Aquilegia, 10 of Thalictrum, 20 of Gentiana, 80 of ferns, 40 of Begonia, 50 of the Araceae. Seed germination tests, micropropagation, breeding for new varieties and other experiments and researches have been carried out on many of these plant groups.
