HARDY WOOI)^ PLANTS 157 



the proportions of a .small tree. Very hardy against cold and drought, but 

 not especially adapted to this soil and climate. It makes an admirable hedge 

 in some localities and will bear shearing well. It also makes fairly good 

 specirnens. On the whole it cannot be very highly recommended on the basis 

 of its performance on the ca.jius. 



Castaiiea puinila. Cii iNurAriN. An attractive shrub of ojien growth some- 

 limes bearing \erv toothsome c(lil)Ie nuts. Suitable for plantings in \\ ild gar- 

 dens. 



('(ifdljia lii(/iioni(/iiles. C'ccm.'mox Catalpa. A medium-si/.ed tree with coarse, 

 broad foliage and attractive flowers. The cataljjas are not entirely hardy on 

 the campus and for tiiis reason not wholly satisfactory. This species is less 

 symmetrical in form and less iiardy than ('. speciutia. 



('((!((! ji<( .\'j)eri(>.\-a. Wkstkhn Catai.i'a. A medium-sized tree with large, coarse 

 foliage and large, quite siiowy flowers borne in abundance in midsummer. If 

 this were not inclined to look shal)by and threadbare, due to insufficient hardi- 

 ness, it would be an attractive lawn tree. It is worth keeping in a large col- 

 lection even w ith its disadvantages. 



Ceanothun amerirnnutt, Jkrsey-tea. A hardy native shrub, small, with good 

 foliage and attractive creamy-white flowers. Suitable for moderately dry, ex- 

 posed situations and may be recommended for frequent planting in such 

 places. • 



Celastrus orbiculatus, Oriental Bittersweet. This species has been exten- 

 sively used on the college campus and is thoroughly satisfactory. The habit 

 of growth is rather better than that of the native bittersweet. Fruits are 

 produced in greater abundance but are scattered and in small clusters, and 

 are less conspicuously decorative. This does fairly well on the shad}- side of 

 buildings and may be used in almost any circumstances where a climbing vine 

 is desired, such as on residence porches, etc. 



Cela.strus .ir((iuleiis, Aimeiucax Bitteusw ki: t. This fine, Iiardy, nati\e climber 

 is one of the best in the whole list and should be gi\en j)rcference in many 

 locations, as house porches and domestic buildings generally. It will stand 

 considerable shade, is very hardy, and the fruits, produced in large clusters 

 at the ends of the season's growth, are highly ornamental. 



Celtis occidentalis, livcKBERRY. One good large sj)ecimen of considerable 

 age — approximately fifty years — has represented this species on the campus 

 along with a few .smaller, younger j)lants. There is nothing striking or espe- 

 cially valuable about this western tree, although it may be grown as an inter- 

 esting curiosity. 



Cephahiiitlui.t ()rrideiiitiH.s. Co.-\i.^iox Buttonbush. A hardy native shrub 

 growing in the borders of ponds and swamps. Rather a good shrub for gen- 

 eral planting in such sitiuitions. Retpiires no special care. 



Cerridiphiillu))! japonk-um. KATsrisA-TisEE. This Japanese tree was early in- 

 troduced into Amherst and to the Agricultural College campus and a number 

 of excellent sjiecimens of approximately fifty years of age are under observa- 

 tion. The tree is shapely and attractive with beautiful clean foliage but usu- 

 ally begins to deteriorate after forty years of age. It is an attractive tree 

 for specimen planting on gromids of moderate size and would always be worth 

 including in a park collection.
