254 DESCRIPTIONS OF THE SHRUBS 



I. Tree to 50 feet ; blooming June, July. Flowering when small 

 and shrub-like ; leaves sour. SOUKWOOD (427) or SORREL- 

 TRKK Oxydendruni arboreum. 



H. Flowers larger, inch long, in side-umbels, white or faintly 

 pink, May-July. A beautiful shrub, 1-4 feet. STAGGER-BUSH 

 (428) Lyonia mariana (Pieris mariana) . 



Erica. The HEATHS and HEATHER are all small-leaved, shrubby plants 

 with usually small 4-lobed, bell- or urn-shaped flowers. The leaves are 

 scale- or linear-shaped and arranged on the stems in alternate, opposite, or 

 whorled positions. The fruit is a 4-celled capsule. But few are in culti- 

 vation in the open in America because of our hot and dry summers. 

 Only three have escaped and grow without cultivation. These are Euro- 

 pean species, although those cultivated in Europe are mainly from South 

 Africa. The African species are practically unknown in America except- 

 ing in conservatories. 



The smaller leaves, the 4-lobed flowers, and the 4-celled fruit will sepa- 

 rate the heaths from the androniedas. [Seeds ; twig cuttings.]
