OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER 

 ZYGOPHYLLA'CE^E. 



36 Melidnthus mdjor L. (Bot. Reg., t. 45., and our Jig. 153.) is a 

 well-known suffruticose green-house plant, admired for the 

 beauty of its glaucous leaves, and the sharp and remarkable notch- 

 ingof its leaflets. It has stood out in many 

 situations in the neighbourhood of London, 

 at the base of a wall, protected only during the 

 most severe weather. It has even flowered 

 in the open air in some situations. In the 

 Oxford Botanic Garden, this plant has stood 

 out for many years at the base of a south wall, 

 and also at the base of an east wall, and has 

 flowered in both situations, the last time in 

 1834. In Devonshire, at Kingsbridge, in the 

 garden of the Moult, it has stood out for many 

 years as a bush ; and, in November, 1835, was 

 between 10 ft. and 12 ft. high. 



Zohllum sessilifbltum L. (figured in 



Bot. Mag., t. 2184. and our fig. 154.), a native of 

 the Cape of Good Hope, and Z. Morgsana L., 



also from the Cape, both green-house plants, 

 which have been upwards of a century in this country, and which are interesting for their peculiar 

 foliage and yellow flowers, may, with other ligneous Cape species, deserve a trial in favourable 

 situations against a conservative wall.
