158 MASS. EXPERIMENT STATION BULLETIN 2(i7 



Cercis canadensis, American Redbitd. This species is hardy here and its 

 brilliant blossoms in early spring are accejatable. It does not thrive with the 

 same exuberance which one sees along the water courses of tlie Central States. 



Cercis chinensis, Chinkse Redbud. This species has also been tried on the 

 college campus but has gone out. It appears not to be hardy. 



Chamaecyparis obtusa, Hinoki Cypress. Trees of this genus considerably 

 resembling the American arborvitae, have been planted quite extensively on 

 the college camjjus. They seem to be entirely hardy and satisfactory. The 

 texture is somewhat finer than with the usual arborvitae and there are diflFer- 

 ences in color and habit of growth which are interesting. Tliey should always 

 be included in any collection of coniferous trees in this part of the country. 

 This 2^a,rticular species resembles the arborvitae more than some of the others. 

 Its foliage is a darker green and glossy and in more compact sprays. 



Chamaecyparis pisifera, Sawara Retixospoua. A good, iiardy, interesting 

 species of this important genus. 



Chamaecyparis pisifera filifera, Thread Retix.ospora. The odd and inter- 

 esting foliage of this variety makes it desirable in a collection. 



Chamaecyparis pisifera plumosa, Plume Retixospora. This variety has a 

 bluish cast of foliage and a striking fine texture which make it more showy 

 than most of the other varieties, ^n this account it may be either more or 

 less desirable, according to the local requirements or one's point of view. 



Chamaecyparis pisifera plumosa aurea, Goldexplume Retixospora. There 

 is always a demand for showy, bright-colored, golden-hued evergreens, and 

 this variety satisfies that desire measurably. It is also perfectly hardy and 

 satisfactory otherwise. 



Chamaecyparis pisifera squarrosa, Moss Retixospora. This variety has sil- 

 ver-gray foliage of very attractive character. For any tree off-color tiiis is 

 about as satisfactorj' as could be wished. 



Chamaecyparis thyoides, Whitecedar. This species is not well represented 

 on the campus, but seems to be as fully available as otlier examples of the 

 same genus. 



Chamaedaphne calyculata, Leatherleaf. A small-leaf native evergreen or 

 low growth, fovmd growing in bogs. The flowers much resemble those of 

 blueberry and are borne suspended from the lower side of the spreading 

 branches. May be used with good effect in a moist situation but is of little 

 value elsewhere. 



Chionanthus retusa, Chixese Frixgetree. This little-known shrub has been 

 growing on the campus for at least forty years and has proved itself per- 

 fectly hardy. In habit of growth and foliage it differs little from the native 

 C. virginica. The flower clusters are somewhat denser and appear a little 

 later than in that species. The large clusters of purple fruit in the fall are 

 an added attraction for a time, but are soon devoured by birds. 



Chionanthus virginica, White Frixgetree. This native species makes a 

 strong large shrub sometimes reaching a height of twenty feet. It is rather 

 coarse and thick in growth without any especially desirable qualities except a 

 fine showing of white flowers in May. At the flowering season it is quite strik- 

 ing and satisfactory. 



Cladrastis lutea. Yellow-wood. A fine, interesting tree native in the states
