PRUNUS 



2X29 



To this form belong the Miner, Langsdon, Clinton, 

 Forest Rose. The Miner is apparently the first horti- 

 cultural variety of native plum to receive a name; the 

 seed that produced the original tree was planted in 1814. 



EE. Stature of bushes: Ivs. and fls. small: far S. W. 

 18. rivularis, Scheele (P. texdna, Scheele). CREEK 

 PLUM. Slender-stemmed shrub to 8 ft., forming thickets, 

 with gray or reddish twigs and early-ripening fr. (June) : 



3221. Prunus angustifolia var. Watsonii (XJi). No. 20. 



Ivs. ovate to oblong-ovate or somewhat obovate, 

 rounded at base, short-acuminate at apex, 1-3 in. long, 

 glandular-serrate, glabrous above, more or less pubescent 

 beneath; petioles with 1 or 2 glands near apex, or gland- 

 less: fls. white, with the Ivs. or before them, less than 

 J^in. broad, on slender glabrous pedicels; calyx-lobes as 

 long as tube, ovate or oblong-ovate, usually pointed, 

 glandular, little pubescent on exterior, with age 

 reflexed; petals obovate-orbicular or oblong-obovate, 

 short-clawed: fr. nearly globose, Hin. or somewhat 

 more diam., red and with fight bloom; pit or stone oval 

 to subglobose, the surface smooth or obscurely rough- 

 ened. Texas. Apparently of little horticultural value, 

 as the fr. is small and poor, although eaten by Indians. 

 No improved varieties are reported. 



19. Reverchonii, Sarg. (P. pygma, Muns., not P. 

 pygmsea, Willd.). HOG PLUM. Shrub, 2-6 ft., with 

 gray bark and chestnut-colored twigs, forming dense 

 thickets and yielding late^ripening fr. (Aug., Sept.) : Ivs. 

 ovate-lanceolate (sometimes lanceolate), acuminate, 

 usually 3 in. or less long, strongly conduplicate, either 

 rounded or narrowed at base, glandular-serrate, gla- 

 brous and green above, pale and somewhat pubescent 

 beneath; petiole bearing 2-4 glands near apex: fls. with 

 the Ivs. or preceding them, white, less than 3-^in. broad, 

 on glabrous pedicels; calyx-lobes oblong or ovate- 

 oblong, obtuse, glandular; petals obovate to oblong- 

 obovate, narrowed or somewhat clawed, entire, or 

 erose near apex: fr. globose or nearly so, sometimes 

 nearly 1 in. diam., usually yellow (rarely red) and 

 blushed with orange or crimson and marked with whitish 

 dots, with little or no bloom; stone oblong, the sur- 

 face smooth or slightly reticulate. Okla., Texas. No 

 horticultural varieties of this species are recorded; its 

 fr. is sometimes good, although usually poor. Said to 

 be well adapted to limestone soils and to withstand 

 drought. Wight writes that the species is closely related 

 to P. rivularis and may be a form of it. "The apparent 

 differences are its more branching and less slender 

 stems, trough-shaped leaves, later-ripening fruit, and 

 more pointed stone." 



cc. Lvs. mostly narrow and peach-like, firm, and more 

 or less shining, glabrous, the young growths not 

 pubescent: fr. thin-skinned: the Chickasaw and 

 Wild Goose set. 



20. angustif dlia, Marsh. (P. Chicasa, Michx. P. steno- 

 phyllus, Raf.). CHICKASAW PLUM. MOUNTAIN CHERRY. 

 Small bushy-topped twiggy tree, 8-10 ft. high or often 

 only a shrub forming dense thickets, with slender 

 zigzag reddish branches: Ivs. lanceolate or oblong- 

 lanceolate and conduplicate (trough-like), shining, 2 

 in. or less long, mostly narrowed toward base, at apex 

 acuminate or short-acute, glabrous or sometimes 

 sparingly pubescent on nerves beneath, finely and 

 closely serrate; petiole glandular or not near apex: 

 fls. white, preceding Ivs., about %in. across, on gla- 

 brous pedicels; calyx-lobes ovate-obtuse and shorter 

 than tube, not glandular, exterior glabrous: fr. small 

 and early, cherry-like, slender-stemmed, red or yellow 

 and yellow-dotted, shining, thinly glaucous, the flesh 

 soft and juicy and clinging to the small rough stone. 

 Del. to Fla. and Texas, being abundant in sandy 

 places. S.S. 4:152. This species has given rise to 

 several pomological varieties, as Caddo Chief and 

 Ogeeche; it is an early-fruiting species, more or less 

 thorny. 



Var. Watsonii, Waugh (P. Watsonii, Sarg.). SAND 

 PLUM. Fig. 3221. Bush, 3-6 ft. high, with more zigzag 

 twigs than in P. angustifolia, more spiny, the Ivs. 

 smaller, less pointed and less conspicuously serrate, the 

 fls. smaller, the fr. with thicker skin. Dry regions of 

 Kans. to Texas and New Mex. (also reported from 

 Neb. but perhaps intro.), and planted by the settlers, 

 who prize it for its fr. G.F. 7:135 (adapted in Fig. 

 3221). Several named pomological varieties issue from 

 this variety, as Strawberry, Welcome, Red, Yellow, 

 and Purple Panhandle. Var. Watsonii is named for Dr. 

 Louis Watson, of Kans. 



Var. varians, Wight & Hedr. BIG CHICKASAW 

 PLUM. Rather larger than P. angustifolia itself, more 

 robust and a less crabbed grower, Ivs. and pedicels 

 longer, and stone usually more pointed at apex. Okla., 

 Texas, in more fertile soil than the species. Apparently 

 a range of forms growing under better conditions than 

 those in which the plants taken as the type of P. 

 angustifolia are found, and giving rise to many early- 

 fruited plums, such as Yellow Transparent, Emerson, 



3222. Leaf of Prunus Munsoniana. The 

 Newman plum (XI). No. 21. 



Coletta, Clark, African. Supposed to have furnished 

 hybrids with P. Munsoniana and P. salicina. The 

 Marianna most probably represents a cross between 

 some form of P. angustifolia (perhaps var. varians) 

 and P. cerasifera. 



21. Munsoniana, Wight & Hedr. WILD GOOSE PLUM. 

 Figs. 3222, 3223; also Figs. 3076, 3077. A range of forms 

 separated out of the old Hortulana class, of larger and 

 freer growth than the variants of P. angustifolia, hardier, 

 with larger and more pointed Ivs., and larger fls. bear- 

 ing glandular calyx-lobes: forming thickets, reaching 

 20-25 ft. in height: Ivs. 3-4 in. long, lanceolate to 

 oblong-lanceolate, rounded at base, at apex acute or 

 acuminate, margins closely glandular-serrate, shining 

 and glabrous, usually slightly pubescent on veins 

 beneath; petioles usually with 2 glands near apex: 

 fls. white, H m - or more broad, either with the Ivs. or 

 preceding them, on slender glabrous pedicels; calyx-
