Pair received three plants of NA 40324 Zelkova serrata and 5 plants of NA 40327 Zelkova serrata as distributions through the National Arboretum. As of 2013, two plants of NA 40324 and 3 plants of NA 40327 still remain at the John C. Pair Horticulture Center (Haysville, Kansas). Accession Ames 32199 was grown from seed harvested by Dr. Jason Griffin from a single specimen of NA 40327. It is likely that pollen from either NA 40324 or NA 40327 could have served as donors. Out of the five specimens of Zelkova serrata currently alive, the single specimen of NA 40327 that was harvested by Dr. Jason Griffin was reported as having the best fall color (2012) and is currently the largest specimen. NA 40324 was originally acquired by the National Arboretum as seed on 1/14/1977 from Masanori Nakamura, Suwa-City, Nagano Prefecture, Japan. NA 40327 was originally acquired by the National Arboretum as seed on 1/18/1977 from the Kyoto University Forest Experiment Station. | 1917225 | Ames 32199 |

The distinguishing feature of this cultivar is that the trunk and second order lateral branches are strongly ascending, while the smaller branchlets are strongly drooping. The rate of growth averages between one and two feet in height per year. A striking specimen plant in most landscape situations. Because of its narrow growth habit and broad ecological tolerance, it also has potential as a street tree. | 1572851 | Ames 25180 |

Thought to be the original Z. schneideriana introduction into Western collections (per Richard Olsen). PI number indicated on card (PI-82353) is in dispute and there are three possibilities: PI-105331 (from a herbarium specimen collected by Fred Meyer in the early 1970s), PI-82353 (received as Z. serrata, this is the number originally attached to NA 59193 and to NA 742, as well as NA 25526 - an Ulmus parvifolia), and PI-98780 (# det. by Santamour for NA 36534, which may also represent this same material.) From PI book for PI-82353 (as Z. serrata): "From Chosen and Japan. Seeds collected by P.H. Dorsett and W.J. Morse, agricultural explorers, Bureau of Plant Industry. Received December 9, 1929. No. 1565. From the Imperial Botanical Garden, Keijo, October 27, 1929. A handsome tree up to 90 feet high, with a short trunk dividing into many upright spreading branches and forming a broad, round-topped head. The sharply serrate leaves are ovate and are usually 2 to 3 inches long, or on young shoots up to 8 inches long." Rooted cuttings of this plant brought to NA to be sent out for evaluation January 1988. None of those were planted at USNA, but later rooted cuttings were grown at South Farm and transplanted there later (see NA 59193.01).
