texana Greene, Leafl. Bot. Observ. 1:220. 1906. Occurs in Texas 
and is easily distinguished from P. vitacea by its 6- to 7-foliolate 
leaves. 
Of the foreign species only the well known “Boston Ivy," so ex- 
tensively planted for the covering of walls and buildings, need to be 
mentioned here; it is Psedera tricuspidata, n. comb.— Ampelopsis 
tricuspidata, Siebold: & Zuccarini, Abh. Akad. Wiss. Muench. 4:88. 
1846.— Parthenocissus tricuspidata Planchon, De Candolle Monogr. 
Phan. 5:452. 1887.— Ampelopsis Veitchii Hort. This species dif- 
fers from its American congeners in having partly three-lobed and 
partly 3-foliolate leaves. As it flowers and fruits freely in southern 
New England, it may possibly soon become naturalized and carried 
even to localities remote from settlements through the agency of birds 
which are often seen feeding on the berries.

B. L. ROBINSON. 
In the course of work at the Gray Herbarium, it has been necessary, 
during the last few months, to assign new names to a considerable 
number of plants (many of them minor varieties and forms), which, 
either from changed views regarding their proper classification or 
more often from the provisions of the Vienna Rules of Botanical 
Nomenclature, can no longer be accurately designated by previously 
existing names and combinations. As the new combinations needful 
must from time to time be employed in the identification of specimens 
for persons preparing local floras or otherwise desirous to mention such 
names in publication, it seems best to record them here briefly with the 
explanatory synonymy.
