MARCH.] GREEN-HOUSE REPOTTING. 125 



to the Hot-house. This plant will not bear much fu- 

 migation. 



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

 has stood in high estimation ever since it was known, 

 but unfortunately there is a very inferior plant, Jlristea 

 cyanea, got into our collections under that name. The 

 panicles of W. corymbbsa is quite smooth; those of Jlris- 

 tea are hairy, which is itself sufficient to detect them ; 

 but otherwise the appearance of W. corymbbsa is much 

 stronger, and more erect growing, not inclining to 

 push at the roots so much as Jlristba. The foliag6 is 

 lanceolate and amplexicaule, the leaves having much 

 the nature and appearance of Iris. The plant is of 

 easy culture, and blooms from November to April ; co- 

 lour fine blue. The true one has come into the 

 country lately. W. ramdsa is a very fine species, simi- 

 lar to the above; flowers yellow and blue; plant 

 branching. 



Westringias, a genus of four species, very like the 

 common Rosemary. W. rosmariniformis, leaves lanceo- 

 late, and silvery beneath ; W. longifblia is similar; both 

 have small white silvery flowers, and are easily culti- 

 vated. . 



Zamias, 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 glaucous. It bears heads of flowers 

 of a brown colour in the centre of the plant, very like 

 large pine cones. Z. horrida, the finest, Z. pungens, Z. 

 spiralis, and Z. latifolia, are the most conspicuous. 

 They must be kept in the warmest part of the Green-
