9t Mrlidnthus 7)i(iJor L. [Bot. Itcj^., t. 45., and owe Jig. 153.) is a 

 well-known suflVuticose grccn-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, rr'~''^j'i 



and also at the base of an east wall, and has /**X-i 



flowered in both situations, the last time in ^""^ 



18.3-t. In Devonshire, at Kingsbridge, in the 



garden of the Moult, it has stood out for many 



years as a bush ; and, in November, 1SJ5, was 



between 10 ft. and I'J ft. high. 

 n. Zygopliyllum scssilifulinm L. (figured in 



Bot. Mag., t. 2IS4, and our/;Vj. 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.
