DESCRIPTION OF SPECIES— LONICERE^. 227 



Vibni'nnni anceps, sp. nov. 

 Plate XXXVIII, Fig. 11. 



Leaf coriaceouB, rounded and acnminate at the top, gradual!}' narrowed downward, palmately 

 three-norved, coarsely obtusely dentate upward. 



A mere fragment, referable to the former described species ]>y its cori- 

 aceous substance onl}'. The leaf is apparently gradually narrowed to the 

 petiole, in the same way as in iig. 1 of the same plate. It has also, like it, a 

 rounded flat top, with a short acumen; but the consistence is thicker, the 

 nervation tripalmate, and the teeth larger, irregular, and obtuse rather than 

 pointed. It has only one pair of secondary nerves, opposite, placed in the 

 upper part of the leaf, and simple. Though evidently a representative of 

 this genus, it seems specifically different from the congeners described above. 



Habitat. — Golden, Colorado. 



Tiburnum Ooldianum, sp. nov. 



Plate LX, Figs. 2-2 c. 

 Seeds oval, obtuse, flattened, smooth, shorf-pediceled. 



These small fruits, very numerous upon the clay of the same locality of a 

 limited area, are referable by their characters to this genus. They appear to 

 have been surrounded by a fleshy envelope, which, though destroyed in the 

 fossil state, has left its original shape molded in the sofl clay. The molds 

 are, therefore, concave inside, and even some of the seeds are inflated on the 

 surface, though always more or less flattened. Figs. 2 b and 2 c represent 

 enlarged the more general forms of these seeds. The size, not very variable, 

 averages four millimeters in width and six to seven in length. 



Habitat. — Golden, Col(Jrado, in soft plastic clay. 



Viburnum solitarium, sp. nov. 

 Plate LX, Fig. 3. 

 Seed large, ovate, obtusely pointed, short-pediceled, flattened. 



This species is closely related to V. macroKptrmum, Heer (Spitzb. Fl., p. 

 60, pi. xiii, figs. 24-28). It is still somewhat larger and more regularly ovate. 



Habitat. — Golden, Colorado. Found separate, in connection with the 

 fragment of leaf of pi. xxxviii, fig. 11, in coarse, sandy clay. 



This seed represents evidently a species different from that to which the 

 seeds of fig. 2 are referable. It would, therefore, be inadvisable to consider 

 all the leaves of Viburnum described here as representing the same species. 

 The living V. molle, V. pubescens, V. dentatum, V. lantanoides, and V. ellipticum
