ROSE-FLO WERING LOCUST. 
Locust cannot be produced, and it will always be good economy to fell it 
within thirty or forty years, or at least, not allow it to grow for timber, to 
a great age. The various kinds of Pine are better adapted to the poorest 
soils.] 
ROSE -FLOWERING LOCUST. 
Robinia vxscosa. R. foliis impari pinnatis ; ramis viscoso glandulosis. 
Obs. Flores roseo-albi. 
This species of Locust is found only on that part of the Alleghanies 
which traverses Georgia and the Carolinas, and in the territory of the 
Cherokee Indians, situated west of the mountains. My father discovered 
it in the summer of 1790, and his subsequent researches, as well as my 
own, confirm the opinion that it does mot exist north of the 35th degree of 
latitude, nor in all the lower part of the Southern States : thus it appears 
to be confined to a very small tract. 
The Rose-flowering Locust is not as large as the preceding species : its 
ordinary stature does not exceed 40 feet, with a diameter of 10 or 12 inches. 
Its branches, like those of the Locust, are garnished with thorns^ which, 
however, are smaller and less numerous. The annual shoots are of a dull 
red color, and are covered with a viscid, adhesive humor : M. Yauquelin, 
of the French Institute, has analysed this substance, and found it to be a 
new vegetable matter. 
The foliage of the Rose-flowering Locust is thick and of a dusky green. 
The leaves are 5 or 6 inches long, and are composed of opposite leaflets, 
10, 12, or 14 in number, with a terminal odd one. The leaflets are about 
an inchin length, oval, nearly sessile, smooth, and of a fine texture. 
The flowers are in oval bunches 4 or 5 inches long. They are numer- 
ous and of a beautiful rose color, but destitute of fragrance. This tree 
not unfrequently blooms twice in the year, and it forms one of the most 
brilliant ornaments of the park and the garden. The seeds are small and 
contained in hairy pods 2 or 3 inches long, and 3 or 4 lines broad. 
Well-informed and unprejudiced cultivators, employed in the raising of 
exotic trees and plants, assure us that seeds of the Rose-flowering Locust,
