L PLANT MATERIAL INTRODUCED 



The crotalarias (Nos. 7587G to 75882, 75970) are interesting legumes which 

 seem promising for use in the South. Some of them are of striking appearance, 

 but even so are more valuable as green-manure plants. 



Cytisus species (Nos. 76035, 76241 to 76247) are being assembled for study 

 to determine whether other species may not be of merit in portions of our country 

 where those already established are useful. They may prove to be of peculiar 

 value from the Middle Atlantic States southward. 



No inventory is complete without mention of grasses, and this list gives proper 

 attention to this huge plant family. 



A large collection of honeysuckles is included in this list. These were assem- 

 bled for study, for many, though distinct botanically, are of little ornamental 

 value, and while several of the species here are far from new, they are so little 

 grown that it was easiest to reintroduce them for the present study. 



Wherever rhododendrons appear, interest is quickened. Rhododendron 

 campanulatum (No. 75966) is one of the relatively newer oriental species which 

 may prove of value in this country. The species (Nos. 76191 to 76195) were 

 collected by Capt. F. Kingdon Ward and presented by Maj. Lionel de Rothschild. 

 They represent some of the more recent fruits of the Ward collecting. 



Final attention may be called to Styrax wilsonii (No. 76275), which seems to 

 be a rather delicate plant somewhat like the familiar and very beautiful S. 

 japonica, which, though old, has never been adequately appreciated. This, 

 with two lilac species, Syringa tomentella (No. 76276) and S. yunnanensis (No. 

 76277), must suffice for the present comment and will show the efforts of the 

 office to keep the interests of the ornamental horticulturists in mind. 



The botanical determinations of these introductions have been made and the 

 nomenclature determined by H. C. Skeels, who has had general supervision of 

 this inventory.
