a single species, D. Howellii, from Southeast Oregon. Greene's 
genus Bebdbia is accepted. Twelve new species are described in 
this supplement. In that to Vol. ii., Part i., thirty new species 
and numerous varieties are characterized. A number of the 
genera are entirely revised. From the tabular arrangement of 
the Gamopetalze we learn that there are now 1,783 indigenous 
North American species, and 102 introduced, mainly from the 
Old World. The supplements and indexes in pamphlet form 
have been issued separately from the volume.

Fraxinus viridis, Michx, thrives best at Eau Claire, 44° N.; 
F. Americana, L., planted in the spring of 1884, is now 7 ft. high 
and 2 inches in diameter, and Catalpa speciosa, Warder, planted ~ 
the same year, also attained 7 ft. in height and 2% inches in 
diameter. 
Tumble-weed. C.E. Bessey. (Botan. Gazette, xi., p. 41.) 
Upon the plains and prairies of the West our common weed 
Amarantus albus grows into a compact plant whose stout, curv- 
ing branches give it an approximately spherical form. The 
autumn winds break the main stem near the ground, and the 
upper part goes rolling and tumbling before the wind, often for 
miles. This is an excellent illustration of the effect of climate on 
the physical development of the plant body, as in the East the 
species is a straggling herb, remaining rooted long after its death 
at the close of the season. Dr. Newberry has told us that it is 
also known as the “ ghost-plant”’ in allusion to the same habit, 
bunches flitting along by night producing a peculiarly weird 
appearance. It is doubtless very efficient in the distribution of 
the seeds, and accounts for the wide dissemination of the species 
on the plains. Professor Bessey notes a similar habit in Baptisia 
tinctorta on Martha’s Vineyard, Mass., and Panicum capillare 
might also be cited as another example.
