other respects require precisely the same treatment as the 

 others. 



CROSS WORT. See Crucianella. 



CROWEA. [Rutaceae.] Greenhouse evergreen shrubs, 

 forming elegant and striking additions to a select collection. 

 When grown slowly they form fine pyramidal branching 

 plants, and are in blooming time studded all over with bright 

 pink stars. When grown in heat, or too much excited by the 

 soil, the stems are more elongated, less clothed with leaves, 

 and the whole plant more naked. Cuttings strike with a 

 little bottom heat in sand, under a bell-glass, and when they 

 have well taken root are potted into three-inch pots ; when 

 taken off, the cuttings should be only two inches long, and 

 one inch of that should be inserted in the sand. These fresh- 

 potted plants must be kept in a close pit until established, 

 and then placed close to the front of the greenhouse, where 

 they may have plenty of air and light. As soon as the pots 

 are filled with roots change them for others a size larger, 

 still keeping them near the glass in the greenhouse, and 

 shifting from time to time from one pot to another. The 

 plants will make side-shoots, and assume a pyramidal shape 

 particularly graceful and handsome. If they are required 

 short and bushy the tops should be taken off soon after the 

 struck cuttings are potted off, as the side shoots push earlier 

 and stronger for it; but then the stopping system having 

 been begun must be continued, so as to keep the plant in 

 form, and to check any branch that may grow too vigorously. 

 The most elegant form, however, is that of the natural growth 

 of the plant, and if not grown too rapidly the bloom wall 

 come abundantly all over the plant alike. The soil must 

 be sandy turfy peat. C. saligna, flowers rose, in July, C. 

 stricta. 



CROWFOOT. See Ranunculus. 



CRUCIANELLA. Crossw^ort. [Oaliaceae.] Hardy peren- 

 •nials and annuals, with two or three requiring stove and green- 

 house temperature. The most desirable is C. stylosa, a 

 trailing plant, forming a pretty subject for rockwork. It is 

 propagated rapidly either by cuttings of the young shoots, or 

 by dividing the plant, and grows readily in common garden 

 soil.
