S. latifdlium, Linn., the Water Parsnip, is a Brit- 

 ish species sometimes naturalized in English wild gar- 

 dens, especially in damp woods. Like Ferula and cer- 

 tain other umbelliferous plants, it is valued more for its 

 stately habit and handsome foliage than for its flowers.

SEtMMIA (Japanese Skimmi, meaning a hurtful 

 fruit). Butdcece. Ornamental evergreen shrubs with 

 alternate entire leaves, small white flowers in terminal 

 panicles and showy bright red berry-like fruit. They 

 are tender, not being reliably hardy as far north as 

 Washington, D. C. Handsome shrubs for borders of 



evergreen shrubberies and especially valuable for plant- 

 ing in cities, as they belong to the best smoke-enduring 

 evergreen shrubs; they are particularly beautiful when 

 covered with their bright red fruits, which are retained 

 through the whole winter if not eaten by birds. In the 

 greenhouse two crops of berries on a plant may be seen 

 occasionally. The Skimmias are of rather slow growth 

 and thrive best in a sandy loamy soil, but also grow 

 well in strong clay; they prefer a partly shaded situa- 

 tion. On account of their handsome fruits they are 

 sometimes cult, in pots in a sandy compost of peat and 

 loam. As the Skimmias are polygamous and mostly 

 unisexual, it will be necessary to plant staminate plants 

 among the pistillate ones to secure well-fruited speci- 

 mens. Prop, by seeds sown in fall or stratified and by 

 cuttings under glass with gentle bottom heat. William 

 Scott writes: "Seeds sown in the fall and grown along 

 in a coolhouse during winter can be planted out in a 

 good loam the following spring, when they will make a 

 vigorous growth, and can be lifted the following Octo- 

 ber. Their red berries make them very desirable as a 

 Christmas berry plant." 



Three species from the Himalayas to China and Ja- 

 pan. Glabrous shrubs : Ivs. dotted with translucid 

 glands: fls. polygamous or dioecious, the staminate fra- 

 grant and in large panicles; sepals and petals 4-5; sta- 

 mens 4-5 ; style with 2-5-lobed stigma : ovary 2-5 loculed : 

 fr. a drupe with 2-4 one-seeded stones. 



Jap6nica, Thunb. (S. obldta, Moore. S. frdgrans, 

 Carr. S. fragrantissima, Hort.). Shrub, 5 ft. high: 

 Ivs. crowded at the ends of the branchlets, short-peti- 

 oled, elliptic-oblong to oblong-obovate, narrowed at both 

 ends, obtusely pointed, bright or yellowish green above, 

 yellowish green beneath, 3}^-5 in. long: panicles 2-33^ 

 in. long: fls. polygamous, usually 4-nierous, yellowish 

 white : fr. coral-red or bright scarlet, subglobose and 

 somewhat angular, M in. across. Spring. Japan. S.Z. 

 1:68. G.C. 11. 25, p. 244; 111. 5, p. 521, 524. Gn. 7, p. 

 183; 35, p. 480; 42, p. 133. J.H. III. 30, p. 525. R.H. 

 1869, p. 259; 1880, p. 56. F. 1865, p. 161. -,S. fragrans 

 and fragrantissima are names of the staminate plant; 

 S. oblata of the pistillate. Var. ovata, Carr., has larger 

 and broader Ivs. R.H. 1880. p. 58. Var. VMtchi, Carr., 

 has obovate Ivs. and perfect fls. R.H. 1880, p. 58. 



F6rtunei, Mast. (S.Japdnica, Lindl.). Similar to the 

 preceding but of dwarfer habit: Ivs. lanceolate or ob- 

 long-lanceolate, acuminate, dark green above, light 

 green beneath, 3K-10 in. long: fls. white, in oblong- 

 ovate panicles, usually perfect: fr. obovate, dull crim- 

 son-red. Spring. China. G.C. II. 25, p. 245 (as 6\ o6- 

 lata); III. 5, p. 525. The following as S. Japonica: 

 B.M. 4719; F.S. 7, p. 39; Gn. 7, p. 183 and 8, p. 519: 

 R.H. 1869, p. 259, and 1880, p. 56. This species fruits 

 more freely than the preceding. Var. rub611a, Rehd. 

 Peduncles, pedicels and buds reddish; staminate form. 

 R.H. 1874:311; 1885, p. 189. Var. arg6ntea, Nichols., 

 has the Ivs. bordered with white. A hybrid between 

 this and the preceding species is probably S. intermedia, 

 Carr., with narrow oblong-elliptic Ivs. dark green above. 

 To this hybrid belong also S. Fdremani, Hort., with lan- 

 ceolate or oblanceolate yellowish green Ivs. and subglo- 

 bose and obovate fr. on the same panicle (G.C. III. 

 5:553) and S. BSgersi, Hort., with similar but deep 

 green Ivs. and globose squarish fruit. 



S. Lauriola. Sieb. & Zucc. Shrub, 5 ft. high, of a strong aro- 

 matic odor when bruised: Ivs. narrow-oblong to obovate, acute 

 or acuminate, bright green: fls. 5-meroiis. Himahiyas.

SEIKRET (Slum Sisarum, Linn.) is a vegetable of 

 minor importance the roots of which are used like salsify 

 or oyster plant. It is a hardy, perennial, umbelliferous 

 herb, native to eastern Asia. It grows ,3-4 ft. high, has 

 pinnate foliage and small white fls. in compound umliels. 

 The roots grow in large clusters, something like those 

 of a sweet potato or dahlia, but they are much longer, 

 more cylindrical and somewhat jointed. The roots have 

 a sweet and slightly floury taste and if well grown are 

 tender. The chief ob.iection to this vegetable is the 

 woody core, which must be removed before cooking, as 

 it is not easily separated from the fleshy part at the 

 table and detracts from its quality. The thickness of 

 the core varies greatly, no matter whether the plants 

 are propagated by seed, offsets or division of roots.
