DESCRIPTIONS OF THE SHRUBS 



broadened up and down, parallel with the stems, instead of cross- 

 wise as in most plants. Such leaves cast but little or no shade. Many 

 of the Acacias, p. 132, illustrate this kind of foliage. Hardy only in 

 southern California and Florida but cultivated in greenhouses North. 

 The flowers are in spikes, at the start, at the end of the branches with 

 long conspicuous stamens ; after flowering, the tips of the clusters grow 

 ■ into shoots and the fruit, many-seeded small capsules, remaining on for 

 years, mark the annual growth of the stems. [Twig cuttings ; seeds.]
