CISSUS 



CISTUS 



Ifts. stalked, ovate, abruptly acuminate, coarsely 

 serrate, green with sunken nerves above and red with 

 prominent nerves beneath: fls. light yellow, in a loose 

 panicle or cluster about 4 in. long, the pedicels recurved 

 after flowering; petals oblong, much reflexed (about 

 3^in. long): berry globose, %in. diam., dark purplish 

 black. Trop. Afr. (Uganda). B.M. 8278. A quick- 

 growing plant requiring warmhouse conditions. Readily 

 prop, by cuttings or seeds, and of very easy cult. 

 Thrives well in sunlight. A recent 

 intro. 



AA. St. not herbaceous at maturity, 



although perhaps fleshy. 

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



4. acida,Linn. Low glabrous climber, 

 with slender and striate somewhat 

 fleshy branches and long stout tendrils: 

 Ivs. rigid, petiolate; Ifts. or If .-divisions 

 rather small, broad-cuneate and sharply 

 toothed near the apex: fls. small, in 

 corymb-like or umbel like clusters: fr. 

 an ovoid and abruptly pointed dark 

 purple berry, with 1 or 2 large seeds, 

 the pedicel being recurved at maturity. 

 S. Fla., and Trop. Amer.; also, in Ariz, 

 and S. Sometimes planted. 



5. incisa, Desm. (C. Rochedna, 

 Planch.). Climbing 20-30 ft., the sts. 

 warty and 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 and the lateral 

 ones 2-lobed: fls. in umbel-like mostly 

 3-forking cymes opposite the Ivs.: fr. 

 an obovoid blackish berry, with 1 or 2 

 seeds, the pedicel being strongly re- 

 curved. Fla., to Ark. and Texas. R.H. 

 1884, pp. 272-3. Often planted in the 

 extreme S. Sometimes called "marine 

 ivy." 



BB. Lvs. not fleshy. 

 c. The Ivs. 3-5-foliate. 



6. gongylddes, Planch. (Vltis gongy- 

 Ibdes and V. pterophora, Baker). Vigor- 

 ous tendril-climber with 4-angled 

 branches, desirable for large green- 

 houses where tropical effects are de- 

 sired, sending down long bright red 

 aerial roots: Ivs. large, stalked, 3-folio- -- 

 late; Ifts. rhomboid or the middle one 

 often 3-lobed, the lateral ones some- 

 times lobed on the outside at the base, hairy on 

 margin and nerves : fls. red-brown, in pedunculate cymes 

 opposite the Ivs. : a tuber (reaching 5-6 in. long) is borne 

 at the end of each branch when the season's growth has 

 ceased, and this drops and produces new plants. Brazil. 

 B.M. 6803. Gt. 37:1273. R.H. 1908:203. 



7. striata, Ruiz & Pav. (Ampeldpsis sempervirens, 

 Hort.). Low, shrubby evergreen vine, tendril-climbing, 

 the branches striate and usually lightly hairy: Ivs. 

 small, 3-5-foliolate, with cuneate-obovate or lanceo- 

 late coriaceous Ifts., serrate above the middle: fls. 

 yellowish, in many-fld. pedunculate cymes opposite the 

 Ivs.: fr. depressed-globose, size of small pea, often 2- 

 celled and 2-4-seeded. Chile, S. Brazil. Graceful small 

 climber for the cool greenhouse; robust in S. Calif. 



cc. The Ivs. not compound although perhaps lobed. 



8. discolor, Blume. Fig. 968. Tendril-climber, 

 smooth, but not glaucous, the branches slender and 

 with 4 or 5 ribs or angles, red: Ivs. oblong-ovate or 

 cordate-ovate, acuminate, bristly serrate, reddish be- 

 neath, velvety green and mottled with silvery white

above: fls. small and yellowish, in dense and very short 

 axillary peduncled clusters: fr. globular, 1-seeded. Java. 

 B.M. 4763. Lowe 13. F.S. 8 : 804-5. One of the best 

 of warmhouse foliage plants. Easily grown. Prop, by 

 cuttings. It must have a season of rest, usually in 

 spring or early summer. If wanted for winter growth, 

 temp, must be about 75. It thrives in rich somewhat 

 moist soil and responds to small applications of fer- 

 tilizer now and then. The plant is very susceptible to 



root - knot. Variable. 

 Known to some as 

 "trailing begonia." 



Var. mollis, Planch. 

 (C. veliitinus, Lind.). 

 Pubescent or velvety: 

 Ivs. green and boldly 

 veined with white 

 above, blood-red 

 beneath : fls. intense 

 bright red, in large 

 laxer and longer-pe- 

 duncled cymes. Habi- 

 tat unknown. B.M. 

 5207. 



9. antarctica, Vent. 

 (C . Baudinidna, 

 Brouss.). KANGAROO 

 VINE. Upright shrub, 

 but the branches climb- 

 ing by tendrils, hairy: 

 Ivs. rather thick, 

 glossy, ovate to oblong, 

 sometimes more or less 

 cordate, very short- 

 acuminate, mostly 

 toothed or notched, 

 green: fls. green, in few-fld., axillary 

 clusters: fr. a globular- or few-seeded 

 berry, said to be edible. Austral. B.M. 

 2488. Valuable for cool greenhouses, 

 but does not withstand frost. Grows 

 well on walls in darkish and neglected 

 places. 



10. sicyoides, Linn. Tall, tendril-climbing, pubes- 

 cent, the branches terete or compressed, tuberculate or 

 smooth, striate: Ivs. ovate or oblong, often cordate at 

 base, margin more or less serrate with bristle-tipped 

 teeth or even cut, thickish, green: infl. corymb-like, 

 opposite the Ivs., the fls. small, and varying from green- 

 ish to white and purplish: fr. an obovoid, 1-seeded black 

 berry. Very widely distributed in Trop. Amer., and 

 exceedingly variable, and extending into Fla. The 

 C. argentea of horticulturists is var. ovata, Baker, which 

 has glabrous ovate or ovate-oblong remotely serrate 

 and somewhat glaucous Ivs. Called "season vine" in 

 tropics. 



It is probable that some of the plants listed as Cissus belong to 

 other genera, and some of the trade names are unidentifiable 

 botanically. C. dlbo-nitens, Hort. Lvs. oblong-acuminate, more or 

 less cordate at base, silvery white and shining over the upper sur- 

 face. Brazil. Warmhouse climber. C. amazonica, Lind. Lvs. 

 glabrous and glaucous, oval-acuminate and narrower, reddish 

 beneath and silvery veined above. Brazil. Warmhouse climber. 

 C. Daridiana, Carr., is a Vitis (which see). C. Lindeni, Andr6 

 (I.H. 17:2), has large ovate-cordate silver-blotched Ivs.: a gla- 

 brous climbing shrub, with terete branches. Colombia. C. por- 

 phyrophylla, Lindl., is a Piper. C. Veitchii, Hort., is Parthenocissus. 



L. H. B. 



CISTUS (ancient Greek name). Cistacese. ROCK 

 ROSE. Low shrubs grown for their red or white hairy 

 flowers. 



Plants usually with villous and glandular tomentum, 

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

 opposite petioles connate at the base: fls. large, in 

 terminal and axillary cymes at the end of the branches, 

 rarely solitary, white to purple; sepals 3 or 5; petals 5; 

 stamens numerous; style elongated or short with a 



Cissus discolor.
