propagated by seeds or by root-cuttings in sandy soil 

 under glass. Ensiformis is perhaps the best of the few 

 cultivated. Under the same conditions may be grown 

 the Dolichos, a tall climber, belonging to the same 

 genus — the Leguminosae. Lablab or lignosus, a green- 

 house evergreen climber, is among the most desirable 

 of the perennial species. Milletia megasperma, a fine 

 evergreen climber of the habit of a Wistaria, may be 

 cultivated in the same manner as the Canavalia and 

 Dolichos. 



Oxypetalum caeruleum is one of the most charming 

 of greenhouse or stove twiners with its pretty flowers 

 changing from pale blue to lilac. It should be planted 

 out in good loam, and is propagated by cuttings of the 

 young shoots in bottom heat. 



In Petrea volubilis we have a pretty purple-flowered 

 stove twiner of tall growth, reaching as much as twenty 

 feet in height. It should be in a warm stove, in good 

 soil, and is propagated by cuttings in brisk heat. 



Hidalgoa Wercklei, called the " Climbing Dahlia," is 

 a recent introduction suitable for the cool house, in rich 

 loam, or for planting out in summer. It is propagated 

 by cuttings.
