260 GREEN-HOUSE REPOTTING. [March 



turn vartegdtum is a very fine variety, and upright growing. 

 These plants are all very desirable, blooming early in spring, 

 and continuing for several months; all easily cultivated. 

 L Soil No. 17 ) 



Westringias, a genus of four species, very like the common 

 Rosemary. W. rosmarinifbrmis, leaves lanceolate, and sil- 

 very beneath. W. longifblia is similar; both have small 

 silvery-white flowers, and are easily cultivated. (Soil No. 2.) 



Witsenias, four species. W. corymbbsa is a plant that has 

 stood in high estimation ever since it was known, but, unfor- 

 tunately, there is a very inferior plant. Aristea cyanea got 

 into our collections under that name. The panicles of W. 

 corymbbsa are quite smooth ; those of Aristea are hairy, which 

 is itself sufficient to detect them ; but otherwise the appear- 

 ance of W. corymbbsa is much stronger and more erect grow- 

 ing, not inclining to push at the roots so much as Aristea. 

 The foliage is lanceolate and amplexicaule, the leaves having 

 much the nature and appearance of Iris. The plant is of 

 easy culture, and blooms from July to November; colour fine 

 blue. W. ramosa is a very fine species, similar to the above; 

 flowers yellow and blue ; plant branching. (Soil No. 8.) 



Yucca aloefblia, and its beautiful variety variegata, are de- 

 sirable plants. They do not bloom till they have grown to 

 considerable size ; but still they make a decided contrast 

 among other plants ; the flowers are white and produced ou 

 terminal spikes. (Soil No. 11.) 



Zdmias, about twenty species, eight of which belong to this 

 compartment. The foliage is greatly admired, and is in large 

 fronds, with oblique, lanceolate leaflets. Several of them 

 glauceous. They bear heads of flowers of a brown colour in 

 the centre of the plants, very like large pine cones. Z. hbr- 

 rida, the finest; Z. pungens, Z. spiralis, and Z. latifblia, are 

 the most conspicuous. They must be kept in the warmest 

 part of the green-house ; and give them large well-drained 

 pots, watering sparingly during winter. They are imported 

 from the Cape of Good Hope. (Soil No. 11.) 



All the plants herein named requiring to be drained, in pre- 

 paring the pots, place first a piece of broken pot, oyster- 

 shell, or any similar substitute, with the convex side on the 

 hole of the pot, and then put in a few, or a handful (accord- 

 ing to the size of the pot) of shivers of brokeu pots, or 

 round gravel about the size of garden beans. Those that
