 (1831). Stems flattened, jointed and 

 notched; flowers from the sides, large, 

 having slender long tubes and a regu- 

 lar arrangement of the petals. Pro- 

 fuse in flowering, with large showy 

 blooms; from the richest crimsons and 

 scarlets to the most delicate rose and 

 blush tints, they are exec-lied in 

 beauty by few decorative plants. 



Epiphytal plants with spineless flatten- 

 ed leaf-like branches, with a prominent 

 midrib, mostly with large showy n 

 from creamy white to the richest crim- 

 son and scarlet, produced from notches 

 in the margin 3 of the sr 



Readily produced by cuttings or seeds; 

 the phyllocacti are established favorites, 

 and hundreds of varieties have been pro- 

 duced by hybridization. Young growth 

 often cylindrical, then triangular, finally 

 assuming the flattened form.
