 tributed C. Parelra, Linn. This plant, as V. helernphuH" , 

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

 tropics. It is known as Velvet-leap and Pareiba 

 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. H. B. 



CiSSUS (Greek name of ivy). VitAcem. Very like 

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

 4's, the corolla not falling oflf 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. 



However, certain 5-merous, disk-bear- 

 ing species are referred in this book to 

 Ampelopsis (C. Ainpelopsis=X. eor- 

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

 has a wide range and many species 

 in warm countries. The latest mono- 

 grapher (Planehon, 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.

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

 wanted for winter growth, temperature must be about 

 73°. Known to some as "Trailing Begonia."

ClSTUS ( ancient Greek name ) . Cistdeece. Rock Rose. 

 Shrubs, usually with villous and glandular tomentum, 

 aromatic : lvs. 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. lauritoUus 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- 

 em aspect. The Cistuses do not bear transplanting well, 

 and should be grown in pots until planted out. Some 

 species yield ladanum, 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, Cistineie (S.C. 

 of the following pages). In the Old World, the Cistuses
