the originator. In the Iowa Horticulttiral Society Report for 1887, Mr. 

 Terry stated that the original tree had borne five crops in succession and 

 he believed it to be the most valuable variety in cultivation for the West 

 and Northwest. The American Pomological Society placed this plum on 

 its fruit catalog list in 1897. 



Tree large, vigorous, rather upright at first, becoming spreading, low-headed, 

 hardy, usually productive, but variable in some locations, susceptible to attacks of 

 shot-hole fungus; branches numerous, dark brown, rough, thorny, with numerous, 

 large lenticels; branchlets long, willowy, with intemodes of medium length, green, 

 changing to dull reddish-brown, shining, glabrous, with numerous large, raised lenti- 

 cels; leat-buds small, short, pointed, appressed. 



Leaves tinged red late in the season, nearly fiat, oval or slightly obovate, two 

 inches wide, four inches long, rather thin; upper surface dark green, smooth, glabrous, 

 with midrib and larger veins deeply grooved; lower surface light green, lightly pubescent 

 along the midrib and larger veins; apex taper-pointed, base very abrupt, margin coarsely 

 and doubly serrate, the serrations often becoming spiny, eglandular; petiole rather 

 slender, nine-sixteenths inch in length, tinged with pink, sparingly pubescent along 

 one side, glandless or with one or two globose, greenish-brown glands. 



Blooming season interraediate in time and length ; flowers appearing with the leaves, 

 showy on account of the numerous, pure white, flat petals, with a somewhat disagreeable 

 odor; borne in clusters on lateral buds and spurs, in pairs; pedicels seven-sixteenths 

 inch in length, glabrous, green with a distinct reddish tinge on one side; calyx- tube 

 red, broadly obconic, glabrous; calyx-lobes short, obtuse, pubescent on both surfaces, 

 eglandular, with a hairy, serrate margin, somewhat reflexed; petals ovate, crenate, 

 but somewhat fringed, long and narrowly clawed; anthers yellowish; filaments five- 

 sixteenths inch long; pistil glabrous, shorter than the stamens. 



Fruit mid-season, ripening period of medium length; about one and one-eighth 

 inches in diameter, roundish-oval or ovate, not compressed, halves equal; cavity un- 

 usually shallow, very narrow; suture an indistinct line; apex roundish; color dull 

 carmine, covered with thin bloom; dots numerous, gray or reddish, nearly obscure, 

 with almost none around the base; stem slender, below medium in length; skin thick, 

 tough, astringent, adhering; flesh pale, dull yellow, very juicy, slightly fibrous, watery 

 and melting, sweet at first with a tart and somewhat astringent after-taste; good; stone 

 adhering to the pulp, seven-eighths inch by five-eighths inch in size, roundish-oval, 

 flattened, smooth, blunt at the base and apex, conspicuously winged on the ventral 

 suture, with a deep but narrow groove on the dorsal suture.
