eral ones, and these seem to have had persistent bnd-scales, wliich have 

 sometimes left quite distinct scars, as in PI. CV, Fig". 1. 



Owing to the leathery character and great durability of the leaves, 

 they niaj- often he found as perfectly preserved as if they had been pressed 

 in a herbarium, even sometimes having a greenish color. They then 

 show the minutest details of their structure. The spiny tip at the ends of 

 the leaves seems to be the prolongation of the midrib beyond the leaf. 

 This tip, however, is not generally preserved. The thick character of tlie 

 leaves has caused them in drying to wrinkle transversel}', as in PI. CVI, 

 Fig. 1*. The leaves are notably thick and i)romincnt. As shown in PI. 

 CV, Fig. 2, the ultimate twigs are terminated by a leaf in a manner similar 

 to cycads. The midrib has two depressed lines running very close to it 

 that leave in some cases two imprints looking like two parallel nerves, as 

 in PL CVIII, Fig. 4, and PI. CIV, Fig 5. These remind one of the two 

 imprints seen in Torrcya. The variation in the size of the leaves does not 

 surpass that seen in CephdotaxHS dnqmcea, which this plant closely resem- 

 bles. The bud-scales seem to have been persistent for some time.

Tree or shrub, with stout branches in whorls or scattered alternately, 

 and in the same 2>hi'iti ; bud-scales persistent at the ba.ses of the shoots of 

 annual growth ; leaves comparatively thin, narrow, tapering gradually to 

 the base and apex, insertion and arrangement of the leaves as in ('. iiuif/i/i- 

 folia ; the leaves have a niaximuin length of 4'"' and a maxinuim width of 

 4""". 



Ijocalities : Fredericksburg, common ; road-side near Potomac Run. 



This plant is much like C. viayiiifol'm, but it is much more cofjiousl}- 

 branched, the leaves are narrower in proportion to their length, have a 

 thinner texture, and a proportionally narrower midrib. It is rather more 

 abundant at Fredericksburg than C. matin'i folia. It may possibly be a foi'm 

 of C magnifolia, but the facies is constant and different from that of this 

 species. The tendency to a whorled grouping of the branches is marked. 

 A common mode of arrangement is that given in PI. CVII, Fig. 3, PI. CIV,
