1. salicornioides, Haw. (Haribta salicornioldes , DC.). 

 Plant upright, reaching a height of 18 in., richly 

 branched ; areolae hardly setulose or lanate: stems 

 cereiform, with cylindric or oblong-elliptic joints : ma- 

 ture or fruiting branches with verticillate, club- or flask- 

 shaped joints, with slender base, all apparently, as well 

 as the fls. and f r. growing from the tops of joints : fls. 

 yellow, funnelform, K in. long: berry small, whitish. 

 Brazil. B.M. 2461. 



2. Saglidnis, Otto (R. brachiata, Hook. Haribta 

 Saglidnis,Lem.). Fig. 2101. Reaching a height of 2ft., 



2101. Rhipsalis Saghonis 



richly branched : long or cereiform branches %-l f t. long ; 

 secondary or fruiting branches oblong-elliptic or short- 

 cylindric, rounded at the ends, spirally or rarely verti- 

 cillately arranged, sometimes weakly grooved, not more 

 than % in. long: areolae with very scanty wool and 2-4 

 short bristles, which on the end branches project as a 

 little brush: fls. near the tops of the short branches, 

 flat, % in. in diam., with 12 white leaves with yellow- 

 ish midstripe: berry white. Uruguav and Argentina. 

 B.M. 4039 (ft. brachiata). 



RHIPSALIS 



3. mesembriantliemoides, Hsn\r.(ffaridta mesembrian- 

 themoides, Lem. ) Upright, the ends drooping, richly 

 branched : long branches 4-8 in. long, 1 line in diam. ; 

 fruiting branches 3-5 lines long, not more than 2 lines 

 in diam., spirally attached, thickly crowded : areolaa 

 sparsely woolly, with 1-2 bristles which project from 

 the ends of the branches: fls. near the top of the joint, 

 about 5 lines in diam., formed of 10 white with yellow 

 midstriped leaves: berry white. Brazil. B.M. 3078. 

 Hardly more than a slender variety of the preceding. 



4. grandifldra, Haw. (R. funalis, Salra.). Branching, 

 cylindrical, rather stout, the branches reaching a height 

 of 3 ft., with a diameter of more than % in.; ultimate 

 branchlets short, often verticillate: areolae depressed, 

 bordered by a red line, sometimes in old branches bear- 

 ing a bristle: fls. wheel-shaped, lateral on the branches, 

 nearly 1 in. in diam. Brazil. B.M. 2740. 



5. Cassytha, Gaertn. Richly branching, pendulous, 

 sometimes 10 ft. long; branches rarely 2 ft. long, 1-1% 

 lines in diam., pale green; ultimate branchlets spirally 

 attached : areolae with sparse woolly hairs and fre- 

 quently 1-2 minute bristles: fls. lateral on the terminal 

 joints, 2-3 lines in diam. : berry like that of the mistle- 

 toe, 1-2 lines in diam. Widely dispersed in Central and 

 S. America, West Indies, Mex., Mauritius, Ceylon and 

 Africa. B.M. 3080. 



6. virgata, Web. Richly branching, pendulous, be- 

 coming a yard long; terminal branchlets hardly more 

 than a line thick, spirally attached : areolse bearing 

 sparse woolly hairs, with an occasional bi'istle: fls. lat- 

 eral, 3-4 lines in diam.: berry only 1% lines in diam. 

 Brazil. Very much like the preceding. 



7. ianthothele, Web. (Pfelffera iunthothelus, Web. R. 

 cereif6rmis , Forst. Pfelffera cereifdrmis, Salm. ) . Stems 

 pendent, 1-2 ft. long, branching, less than 1 in. in diam., 

 4-, rarely 3-angled; ribs tuberculate; areolae at summit 



of tubercles short- 

 woolly, soon na- 

 ked, bearing 6-7 

 short bristles: fls. 

 with very short 

 tube, but the fl. 

 bell-shaped, pur- 

 ple-red without, 

 pure white with- 

 in, nearly 1 in. 

 long, little more 

 than half as much 

 wide: fr. the size 

 of a cherry, rose- 

 red, with bristles 

 like those of the 

 stem. Argentina. 



8. trfgona, 

 Pf eiff . Richly 

 branched, becom- 

 ing a yard long: 

 branches K to 

 nearly 1 in. in 

 diam., 3-angled: 

 areolae sparsely 

 woolly and brist- 

 ly, the blooming 

 areolaamuch more 

 copiously so: fls. 

 greenish outside, 

 white within, 4 or 

 5 lines long. Bra- 

 zil. 



9. paradoxa, 

 Salm. Sparingly 

 branched, 1-2 ft. 



long ; branchlets 1-2 in. long and %-l in. in diam., 

 twisted at the joints, so that the angles alternate with 

 the sides: fls. % in. long, white. Brazil. 



10. pentaptera, Pfeiff. Richly branched, 1-2 ft. long, 

 4-5 lines in diam. : branchlets 2-5 in. long, 5-6-angled or 

 almost winged : areolse in crenatures of the angles with 

 scanty wool and an occasional bristle: fls. greenish 

 white, 3-4 lines long: fr. white, bright rose-red above 

 crowned by the withered flower. South Brazil, Uruguay, 

 Argentina.
