('C .TVATi s; PEClIMENS: Arnold Arboretum, no. 300-41, E.'J. . Palmer, Sept. 8, 1944 (plant received in 1941 from II. F. Stoke, Roanoke, \a.). A very distinct form with bipinnate leaves finely dissected into lanceolate to linear-lanceolate and serrate to pinnattild leatlets 1 3.5 cm. long and 4 -1 mm. wide. In the shape of its foliage and in general appearance this form resembles somewhat Rhus typhina f. dissccta Render, but it is more finely dissected and more graceful: the tree certainly merits attention as a highly ornamental form. With the exception of the laciniate form of the English \alnut. Jutlansregia f. laciniata (Jacques) Schneider, no other form with lacinate leafletswas known in the whole family until the form of J. nigra described abovewas raised. The cut-leaved form of the English Walnut, from which J.rcgia f. hcterophylla (Jacques) Schneider differs but little, is distinctlyinferior as an ornamental plant to the cut-leaved Black Walnut, having arather coarse, very irregularly shaped foliage, and moreover being moretender. According to information kindly furnished by Mlr. J . . Hershey, theowner of the Nut Tree Nurseries at Downingtown, Pa.. about thirty plantsof this form were found in 1926 at the State Nursery at Milton, Pa,, amongseedlings raised from seed collected from normal Black Walnut trees inBuffalo Valley, east of the State Nursery. Unfortunately most of theseedlings got lost, but Mr. Hershey obtained one plant and, recognizing itsornamental value, propagated it so that he was able in 1937 to offer it forsale. The Arnold Arboretum received in 1941 a plant of this form fromMr. H. F. Stoke of Roanoke, Va., with the statement that it originated inPennsylvania: this was probably obtained from the same source as Mr.Hershey's plant.Juglans 'crdiforrnis Maxim var. ailantifolia (Carr.), comb. nov.
