MIOCENE FLORA FROM COASTAL PLAIN 29 
This nearly complete elliptical leaf closely resembles the leaves 
usually referred to this species, although suggestive of the leaflets 
of a number of species of the Papilionaceae. It is about 1.6 cm. 
long by 1.2 cm. in greatest width, with four or five pairs of campto- 
drome secondaries. 
Celastrus bruckmanni was recorded originally from the Tortonian 
of Baden and has since been found at a number of European localities, 
some ranging as low as the Aquitanian. It is recorded by Heer (loc. 
cit.) from the Greenland Tertiary, but has not heretofore been found 
on the North American mainland.

RHUS MILLERI Hollick 
Rhus millert Hollick, Md. Geol. Surv., Miocene, 485. f. Ic, d. 
1904. 
This species which was described by Hollick a 
few years ago from the Calvert formation of the 
District of Columbia is represented by fragmentary specimens in the 
Richmond material. 
In some respects these leaves suggest a relationship with Myrica, 
but the available material is so scanty that it is not desirable to make 
any change in the nomenclature. The missing parts in the figure 
have been restored from the more complete Maryland material, the 
outline of the Virginia specimen being indicated.

This species is based on a lanceolate, somewhat two-sided terete 
stone with about fifteen very narrow longitudinal ridges, possibly 
the remnants of slender wings. Length 8 mm., greatest diameter 
2.5mm., about equally pointed at both ends. ‘The existing species 
of Nyssa number less than a dozen, inhabiting the warm temperate 
region of eastern North America and eastern and central Asia. A 
great many fossil species, founded chiefly upon stones, have been 
described, Perkins alone describing no less than eighteen species, an
