 from the true D. arborea of Linn., but it can be sepa- 

 rated with certainty only by the calyx. Tree-like shrub,

did plants of D.ivallia may be cut into a number of 

 smaller ones with a sharp knife. Planted firmly into 

 shallow pans and placed in a temperature of 60-65° F., 

 they soon develop into symmetrical plants. The rhizomes 

 should be firmly fastened to soil by strong copper-wire 

 staples, where they will root in a short time. To gain 

 a large number of small plants, the rhizomes should be 

 detached, cleaned from all soil and roots, laid on sand 

 and thinly covered with moss. Placed in a shaded posi-
