Since only one or two species of Leptospermum are grown 

 in California to any considerable extent, the detailed botanical 

 descriptions are omitted. 



AGONIS. 



One species of Agonis is grown in California, namely A. 

 flexuosa Schau., of which good examples may be seen in Golden 

 Gate Park and at Soldiers Home, near Los Angeles. The 

 shrub is commonly mistaken for a Leptospermum but is much 

 more graceful in habit and with longer, more slender leaves. 

 Very serviceable where a pendant effect is desired rather than 

 a show of bloom. 



[ METKOSIDEROS. 



This genus includes two magnificent New Zealand trees, 

 grown in California to a limited extent. They may be known 

 by their large size, the thick and leathery strictly opposite 

 leaves, and the rounded, terminal flower-clusters rendered bril- 

 liant by the profusion of long-exserted, crimson stamens. In 

 M. robust a A. Cunn. the leaves are glabrous and 1 to 1% inches 

 long; in M. tomentosa A. Rich, they are usually clothed beneath 

 with white hairs and are mostly 2 to 4 inches long. 



Metrosideros may be used either as an ornamental shrub or 

 as an avenue tree. It is easily propagated by means of cuttings 

 since it is disposed to throw out roots, even on the main branches. 

 In New Zealand ''it commonly commences life as an epiphyte, 

 in the upper branches of some tall forest tree, sending to the 

 ground aerial roots which coalesce and form a trunk after the 

 death of the supporting plant" (Cheeseman).
