IIUI'-IIORNBEAM. 



See iron wood. 



HORNBEAM. 



See bine beech. 



HOP-TREE— Pieiea trifoliata. 



This neat shrub thrives along our river banks. For samples, see arboretum, 

 also tiiickets on the river bank, back of AVells' iiall. 



IRON-WOOD— Os<?7/a Vir(/inica. 



This small slow-growing tree is mcII known in our forests. The wood is 

 very hard, heavy, and fine grained. It is a favorite for levers, beetles, wedges, 

 pins, firewood, etc. Samples may be found on the bank nortli of the chemi- 

 cal laboratory, also in the grove southwest of Williams hall. 



IVY, AMERICAN. 



See Virginia creeper. 



IVV, I'OISON- ii;»ws toxicodendron. 



No plant on the College grounds is more famous than poison ivy, especially 

 among that class of students who are poisoned by it. It trails along the ground 

 or climbs trees. It has leaves composed of three leaflets. The American ivy 

 has five leaflets. The latter is perfectly harmless and is justly a great favor- 

 ite. Specimens of poison ivy can be seen (or handled) on the river bank 

 almost any where south of the President's house, also one on an elm tree not 

 far from the river near the four corners west of the College ; also a labeled 

 specimen on an island of the pond of the wild garden. 



.JUNE 'BJLTiIlY—Amela7ie?iier Canadensis. 



This beautiful shrub abounds in open woods in this vicinity. It varies a 

 good deal in shape of leaf, mode of growth, etc. There arc some dwarf forms. 

 It puts forth an abundance of white flowers early in spring before tlie appear- 

 ance of the leases. It is worthy of a place among our ornamental shrubs, 

 especially where tlie winters are very severe. For specimens, look on tlie south 

 side and near the drive and west of the rustic road bridge, also about the api- 

 ary, also in the arboretum, also in the grove south of Professor Cook's house. 



JUNIPER, llllSll—Juniperis couimunis JJiberiiica. 



As the Jjatiu name indicates, this is only one variety of our list of common 

 junipers winch are found in Europe and Asia as well as in North America. 

 The variety is quite distinct in form. It is erect, often much the shape of a 

 miniature Lombardy pojflar. Tiic leaves are short, sharp-])ointed, glaucous 

 green in whorles of three on the small limbs. The center of the shrub is too 

 apt to be injured by our cold winters. It is especially valuable in formal gar- 

 dens. At the College, one of the largest specimens grows north of and near 

 College Hall ; also in tlie arboretum. Tlie large specimen came from the 

 botanical garden, Cambridge, Mass. 



JUNIPER, SWEDISH— Juniper communis Succlca. 



Tiiis is much like the Irish juni})er, only of a brighter color and more hardy. 

 It attains a heigiit of fifteen feet or more, and bears trimming well. See 

 sample on the rockery northwest of the greenhouse.
