M. Celsidna is C. tanacetifolia 'Leechia Arb. Brit. When we gave the plant 



this name, we believed, as we were informed, that it was a seedling raised

catalogue of the Derby Arboretum.

found by removing a portion of the bark.

 £/'lmus camp^stris latifolia is U. montana Arb. Brit,

U. effusa of the Hort. Soc. Garden and the Arb. Brit. ; but whether it 



is a native or not is uncertain. 

 TJ. exoniensis is the U. montana fastigiata Arb. Brit. 

 U. americana is without doubt the eft'iisa Arb. Brit., and quite different from 



the U. pedunculata mentioned above. The leaves of this species, both 



in England and France, have a tinge of red on the veins. From speci- 

 mens received from Dr. Torrey, we believe this plant to be correctly 



named. 

 U. pyramidata is U. campestris pyramidata, a very distinct variety, with a 



conical habit. 

 Celtis mississippiensis Bosc, very distinct.
