CISSAMPELOS 



CIST US 



petals united, the anthers 2-4, on a staminal column ; 

 fertile fls. with 2 united fleshy sepals, subtended by a 

 sepal-like bract, and solitary ovary, with 3 styles : fr. a 

 subglobose drupe, with a flattened and tuberculate stone. 

 Many species or distinct forms in tropical regions, but 

 many of them are evidently forms of the widely dis- 

 tributed C. Pareira, Linn. This plant, as C. heterophylla, 

 DC., and under other names is cult, in S. Fla. and the 

 tropics. It is known as VELVET-LEAF and PAREIRA 

 BRAVA. It is an exceedingly variable vine, with downy, 

 round-cordate or peltate Ivs., the sterils fls. in stalked 

 corymbs and the fertile in large-bracted racemes, and a 

 hairy, nearly globular, red fruit. It occurs in all tropical 

 countries. L_ jj g 



ClSSUS (Greek name of ivy). Vitdcece. Very like 

 Vitis, but differing in having the parts of the flower in 

 4's, the corolla not falling off as a cap, and the disk 

 about the ovary ring-like or cup-like. Ampelopsis is 

 distinguished by 5-merous fls. and the absence of a disk. 



473. Cissus discolor. 



However, certain 5-merous, disk-bear- 

 ing species are referred in this book to 

 Ampelopsis (C. Ampelopsis=A. cor- 

 data, G. stans=A. arborea). Cissus 

 has a wide range and many species 

 1 in warm countries. The latest mono- 

 grapher (Planchon, DC. Monogr. 

 Phaner. 5) recognizes 212 species. Foli- 

 age often fleshy, but in most of the cult. 

 species usually thin and handsomely 

 colored or variegated. The species of 

 Cissus are handsome, tall-climbing, 

 tendril-bearing vines, of easy cultiva- 

 tion. 



A. Lvs. fleshy, 3-lobed or 3-foliolate. 



acida, Linn. Low climber, with slender and striate 

 somewhat fleshy glabrous branches : Ifts. or leaf -divi- 

 sions rather small, broad-cuneate and sharply toothed 

 near the apex : fls. small, in corymb-like or umbel-like 

 clusters: fr. an ovoid and mucronate dark purple berry, 

 with 1 or 2 large seeds, the pedicel being recurved at 

 maturity. Key West and S.; also, in Ariz, and S. 

 Sometimes planted. 



incisa, Desm. (C. Rochedna, Planchon). Climbing 

 20-30 ft., the stems very fleshy and the tendrils root- 



<\ 



like : Ivs. pale green, very fleshy ; Ifts. or divisions 

 wedge-ovate, notched on both sides and top, the middle 

 one sometimes again lobed : inflorescence umbel-like: 

 fr. an obovoid blackish berry, with 1 or 2 seeds, the 

 pedicel being strongly recurved. Fla., to Ark. and Tex. 

 R.H. 1884, pp. 272-3. -Often planted in the extreme S. 

 Sometimes called "Marine Ivy." 



AA. Lvs. not fleshy, not lobed. 



discolor, Blume. Fig. 473. Lvs. oblong-ovate, acumi- 

 nate, cordate at base, bristly serrate, reddish beneath, 

 velvety green and mottled with silvery white above: 

 both Ivs. and stems glabrous, the latter red and more or 

 less angled: fls. small and yellowish, in dense and very 

 short, axillary clusters. Java. B.M.4763. L. 13. F. S. 

 8:804-5. One of the best of all warmhouse foliage 

 plants. Easily grown. Prop, by ciittings. Must have a 

 season of rest, usually in spring or early summer. If 

 wanted for winter growth, temperature must be about 

 75. , Known to some as "Trailing Begonia." 



Antarctica, Vent. ( C. Baudinidna, Brouss. ) . KANGA- 

 ROO VINE. Lvs. rather thick, glossy, ovate to oblong, 

 very short-acuminate, rounded at base, mostly strongly 

 toothed or notched, green: fls. green, in few-fld., axillary 

 clusters : fr. a globular berry. Austral. B. M. 2488. 

 Valuable for cool greenhouses, but does not withstand 

 frost. Grows well on walls in darkish and neglected 

 places. 



Amazonica, Linden. Lvs. glabrous and glaucous, oval- 

 acuminate and narrower, reddish beneath and silvery 

 veined above. Brazil. Warmhouse climber. 



albo-nitens, Hort. Lvs. oblong-acuminate, more or 

 less cordate at base, silvery white and shining over the 

 upper surface. Brazil. Warmhouse climber. 



sicyoides, Linn. Branches terete or compressed, tu- 

 berculate or smooth, striate: Ivs. ovate or oblong, often 

 cordate at base, margin more or less serrate or even 

 cut, thickish, green: inflorescence corymb-like, opposite 

 the Ivs., the fls. small, and varying from greenish to 

 white and purplish : fr. an obovoid, 1-seeded berry. 

 Very widely distributed in trop. Amer., and exceedingly 

 variable. One form (var. Floriddna, Planch.), occurs in 

 S. Fla., but is not in the trade. The C. argSntea of hor- 

 ticulturists is var. ovata, Planch., which has glabrous 

 ovate or ovate-oblong remotely serrate and somewhat 

 glaucous Ivs. Called "Season Vine" in tropics. 



C. Davidiana,Ca,TT., is a Vitis (which see). C. Lindeni, Andre 

 (I.H. 17:2), is perhaps an offshoot of C. sicyoides. It has large 

 ovate-cordate silver-blotched Ivs. C. Japonica, Willd. Her- 

 baceous, glabrous: Ivs. 5-foliolate, with serrate-oblong Ifts.: 

 fls. greenish ; cymes many-fld. Jap., Java, Austr. The only 

 species hardy north. C. porphyrophylla, Lindl., is a Piper 

 (which see). C. striata, Ruiz. & Pav. (Ampelopsis sempervi- 

 rens, Hort.). Low, shrubby evergreen vine: Ivs. small, 5-folio- 

 late, with cuneate-oblong Ifts., serrate above the middle : fls. 

 yellowish, in many-fld. cymes. Chile, S. Braz. Graceful small 

 climber for the cool greenhoxise. C. Veitchii, Hort.=Ampe- 

 lopsis tricuspidata. L. H. B. 



ClSTUS (ancient Greek name). Cistcicece. ROCK ROSE. 

 Shrubs, usually with villous and glandular tomentum, 

 aromatic : Ivs. opposite, mostly persistent, entire, the op- 

 posite petioles connate at the base: fls. large, in terminal 

 and axillary cymes at the end of the branches, rarely 

 solitary, white to purple ; petals 5 ; stamens numerous ; 

 capsule many-seeded, splitting into 5 valves. About 30 

 species in the Mediterranean region. Ornamental, free- 

 flowering shrubs, usually only a few feet high, with very 

 .showy purple or white fls., similar to a small single rose, 

 appearing in early summer. They are only hardy in 

 warmer temperate regions, but many of them will stand 

 10 of frost without injury, and C. laurifolius even more. 

 They thrive best in a well drained, light soil, mostly 

 preferring limestone soil, and in a sunny position ; the 

 dwarf er species are well adapted for rockeries with south- 

 ern aspect. The Cistuses do not bear transplanting well, 

 and should be grown in pots until planted out. Some 

 species yield ladamim, a resin, used in perfumery. -Prop, 

 by seeds sown in spring in pans or boxes and the young 

 seedlings shaded ; increased also by layers and cuttings 

 in spring or late summer, inserted in sandy peat under 

 glass. Illustrated monograph: R. Sweet, Cistinese (S.C. 

 of the following pages). In the Old World, tbe Cistuse<?
