CRAT7EGUS CRUS-GALLI, L. 117 



Horticultural Value. Hardy throughout New England ; 

 grows in all soils and situations except in wet lands, but 

 prefers deep, rich, moist loam ; very irregular in its habit of 

 growth, sometimes forming a shrub, at other times a slender, 

 unsymmetrical tree, and again a symmetrical tree with well- 

 defined trunk. Its beautiful flowers, clean growth, attractive 

 fruit and autumn foliage make it a desirable plant in land- 

 scape plantations where it can be grouped with other trees. 

 Occasionally in nurseries ; procurable from collectors.

CKAT^GUS. 



A revision of genus Cratcegus has long been a desideratum 

 with botanists. The present year has added numerous new 

 species, most of which must be regarded as provisional until 

 sufficient time has elapsed to note more carefully the limits 

 of variation in previously existing species and to eliminate 

 possible hybrids. During the present period of uncertainty 

 it seems best to exclude most of the new species from the 

 manuals until their status has been satisfactorily established 

 by raising plants from the seed, or by prolonged observation 

 over wide areas.
