SINNINGIA 



SIPHOCAMPYLUS 



cessive pairs of leaves are usually close together on the 

 stem, the effect is that of two many-flowered whorls, 

 and is very fine." Brazil. G.C. III. 36:201. B.M. 8182. 

 Gt. 53, p. 525. G.W. 9, p. 277. A handsome plant, 

 with long flowering period. Var. hybrida, Hort., is a 

 garden hybrid with much larger fls. Var. grandiflora, 

 Hort., is advertised, the fls. "several times larger than 

 the type, and well displayed above the handsome dark 

 green and pur push red foliage." 



conspicua, Nichols. (Rosanbwia conspicua, Regel). 

 Root tuberous: st. 1 ft. high: Ivs. ovate-oblong, short- 

 acuminate, somewhat heart-shaped at the base and 

 dentate: fls. yellow, paler on the outside, marked on the 

 lower part of the tube with purple dots and lines; calyx- 

 tube [entirely united with the ovary, equally 5-parted, 

 the segms. lanceolate, spreading; corolla-tube obliquely 

 and narrowly campanulate, swollen and recurved at the 

 base; glands of the disk 2: caps. 1-celled; seeds many. 



ornata, Benth. & Hook. (Rosanbwia ornata, Van 

 Houtte). A hybrid of the above species with a garden 

 variety of Gloxinia with fls. of a bright red; the result is 

 a plant resembling S. conspicua, but differing in having 

 the Ivs. tinted on the veins and petioles with purple and 

 in having a somewhat more elegantly shaped fl., pure 

 white with purple lines on the outside of the corolla- 

 tube and the inside of a yellowish green, lined with 

 purple. F.S. 23:2423. Probably not now in the mar- 

 ket. L. H. B.f 



SINOFRANCHETIA (for Adrien Franchet, French 

 botanist who wrote much on Chinese botany). Lardi- 

 zabalacese. Deciduous climbing shrub allied to Hol- 

 boellia, but easily distinguished by the deciduous Ivs., 

 by the rounded small sepals of the fls. borne in very long 

 racemes and by the small berry-like frs. The only 

 species is S. chinensis, Hemsl. (Holboellia chinensis, 

 Diels). Twining, to 30 ft., glabrous: Ivs. long-petioled, 

 3-foliolate; Ifts. stalked, short-acuminate, broadly 

 cuneate at the base, entire, the terminal broadly obo- 

 vate, 4-5 in. long, the lateral Ifts. obliquely ovate: 

 racemes axillary, 8-12 in. long; fls. unisexual, short- 

 stalked, J^in. across, white striped brownish; sepals 

 pbovate; stamens 6, free, short: carpels 3, developing 

 into ovoid many-seeded, bluish purple berries about 

 %in. across. Cent. China. H.I. 29:2842. The long 

 racemes of bluish purple berries are strikingly hand- 

 some: the plant has proved perfectly hardy in southern 

 England, but is tender at the Arnold Arboretum. Prop, 

 is by seeds and by layers, possibly also by cuttings like 

 akebia. ALFRED REHDER. 



SINOMENIUM (Sina, China, and Greek, men, 

 moon, meaning Chinese moon-seed). Menispermaceae. A 

 shrubby vine from E. Asia closely related to Menisper- 

 mum and Cocculus; from the first it differs in the parts 

 of the fl. being arranged in whorls and in the 9-12 sta- 

 mens, and from the second chiefly in the structure of the 

 flattened curved seed: Ivs. deciduous, alternate, long- 

 petipled: fls. direcious, small, in axillary and terminal 

 panicles; sepals 6, pilose outside; petals 6, inflexed at 

 the base and inclosing the filaments; the pistillate fls. 

 with 9 staminpdes and 3 carpels with recurved styles: 

 fr. a drupe with a compressed crescent-shaped stone 

 ribbed on the back. A handsome vigorous-growing 

 twining vine with large lustrous often lobed Ivs. remain- 

 ing green until late in autumn, with inconspicuous fls. 

 in long pendulous racemes and bluish black frs. It 

 has proved only half-hardy at the Arnold Arboretum. 

 Prop, like cocculus and menispermum. 



acfttum, Rehd. & Wilson (S. diversifdlium, Diels. 

 Menispermum acutum, Thunb. Cocculus diversifolius, 

 Miq., not DC. C. heterophyllus, Hemsl. & Wilson. C. 

 variifdlius, Hort.). Twining, to 20 ft. : branchlets terete, 

 striped, glabrous: Ivs. long-stalked, ovate, acuminate, 

 usually cordate at the base, palmately 5-7-nerved, 



entire or palmately lobed, rarely sagittate with 2 lobes 

 at the base only, glabrous, 4-7 in. long: fls. K m - across, 

 greenish, in slender panicles 4-8 in. long: drupes com- 

 pressed, bluish black, J^in. across, in pendulous pani- 

 cles to 8 in. long. June; fr. in Sept. and Oct. Japan 

 and China. G.C. 111.52:411. Var. cinereum, Rehd. & 

 Wilson. Lvs. densely grayish pubescent beneath.

SINOWILSONIA (for Ernest Henry Wilson, who 

 collected extensively in China during 1900-1910 and 

 intro. numerous new plants into cult.) . Hamamelidaceae. 

 A deciduous tree similar in foliage to Hamamelis, but in 

 its fls. more closely related to Corylopsis, from which it 

 is chiefly distinguished by the unisexual, apetalous fls., 

 and the tubular-urceolate calyx-tube: fls. in pendulous 

 racemes; tube of the calyx urceolate, inclosing the ovary, 

 with obovate-spatulate lobes; petals wanting; the pis- 

 tillate fls. with 5 staminodes opposite to the sepals; 

 ovary with 2 long and slender styles: fr. a dehiscent 

 2-seeded woody caps. The only species is S. Henryi, 

 Hemsl. Shrub or tree, to 25 ft., more or less stellate- 

 pubescent: Ivs. short-petioled, membranous, broadly 

 obovate to elliptic, acute or short-acuminate, denticu- 

 late, 4-6 in. long: calyx-tube yellowish, stellate-tomen- 

 tose, nearly K m - long: caps, sessile, nearly J^in. long; 

 seeds black. May. Cent, and W. China. H.I. 29:2817. 

 Botanically interesting, but without particular orna- 

 mental qualities; has proved hardy at the Arnold 

 Arboretum. Prop, is by seeds and probably by layers 

 and by grafting on hamamelis. ALFRED REHDER. 



SIPANEA (native name in Guiana). Rubiacex. 

 Annual or perennial herbs, hispid-setose, pilose or gla- 

 brate, erect or prostrate, with terete branches: Ivs. 

 opposite, petiolate, ovate or lanceolate; stipules linear, 

 elongate, persistent: fls. paniculate or cymose, the 

 cymes in corymbs, axillary, terminal or dichotomously 

 disposed, white or rose, the throat frequently golden 

 villous; calyx-tube turbinate or ovoid, the limb with 5 

 elongate-subulate, persistent lobes; corolla funnelform 

 or salver-shaped, tube elongated with the throat dilated, 

 the limb with 5 equal, broad-ovate spreading lobes; 

 stamens 5; disk annular; ovary 2-celled: caps, ovoid or 

 subglobose, leathery. About 5 species, Trop. Amer. 

 S. cdrnea, Neumann. Perennial herb, about 3 ft. or 

 more high: Ivs. oval, lanceolate, acute: fls. pale rose- 

 violet, arranged in a corymb; corolla-tube cylindrical, 

 5-parted, oval, acute: fr. hemispherical. Cent. Amer. 

 H.U. 4, p. 193. R.H. 1843:445. 



SIPHOCAMPYLUS (Greek, siphon, tube, and 

 kampylos, curved, referring to corolla) ; sometimes mis- 

 spelled Syphocampylus. Campanulacese. Herbs, sub- 

 shrubs, or shrubs, sometimes climbing, glabrous, hir- 

 sute or stellate-tomentose, adapted to the warm- or 

 coolhouse: Ivs. alternate, rarely verticillate, entire or 

 denticulate, rarely incise-dentate or pinnately lobed or 

 divided: peduncles 1-fld., axillary or corymbosely 

 grouped at the ends of the branches or laxly racemose : 

 fls. often rather large, red, orange, or purplish, rarely 

 green; calyx 5-lobed; corolla straight or incurved: caps, 

 loculicidally 2-valved. About 100 species, Trop. 

 Amer. 



betulaefdlius, Don. Height 2-3 ft. : st. woody at base: 

 branches rounded: Ivs. alternate, petiolate, 3-4 in. long, 

 cordate, acuminate, doubly serrate, nearly glabrous: 

 peduncles 1-fld., as long as the Ivs., thickened upward: 

 calyx-segms. long awl-shaped, with a few notches; 

 corolla 2J/2-3 in. long, tube vermilion, limb yellow. 

 Brazil. B.M. 3973. H.U. 5, p. 97. Tender perennial, 

 not cult, in Amer., but interesting as one supposed 

 parent of Centropogon Lucyanus, itself of little value. 



S. bicolor, Don=L,obelia lariflora, HBK. S. gigant&us, Don 

 (Tupa salicifolia, Don) grows 14 ft. high: Ivs. lanceolate, 6-9 in. 

 long, scarcely petioled: fls. reddish yellow; corolla falcate, velvety. 

 Ecuador. S. Lindleyi, Lem., has ovate-oblong, glandulose-serrate
