182. Cornus Studeri ? Heer. 



"P. Y. station, near Messa station;" received from W. S. Yeates; 

 one specimen. 



Agrees with the figure and description in Heer Fl. Tert. Helv., p. 27, 

 PI. OV, f. 18-21. The two lower pairs of nerves from above the base are 

 opposite, but the acute divergence of the secondaries is the same. As 

 the upper part of the leaf is destroyed the identification is not certain.

185. Crataegus Holmesii, u. sp. PI. Ill, Figs. 7-9. /"^ ^ / u.w/^'*--^'' 

 Ryolite beds, Silver Cliff, Colo. ; W* H. Holmes, collector. 



Leaves small, coriaceous, oblanceolate-spathulate, gradually narrowed 

 to the base from an obtuse truncate or acute apex; primary nerve 

 broad ; secondaries thick, very oblique, simple, parallel, the lowest pair 

 opposite and emerging from above the base of the leaf. The leaves, 

 mostly in fragments, vary from 18 to 30 millimeters long, 4 to 10 millime. 

 ters broad above the middle or in the upper part, gradually decurriug to 

 a comparatively long petiole 15-16 millimeters long, inflated at the point 

 of attachment ; secondaries 5-6 pairs, at an angle of divergence of 

 about 20°, deeply impressed upon the leaf which appears thus folded 

 along them and simply dentate on the borders by the excurriug points 

 of the nerves. These leaves resemble those of Cratcegus spatJmlata Mich, 

 and also of C. tomentosa in some of the varieties, being however much 

 smaller. But for the long petiole and the nervation very distinct, not 

 obscured by intermediate nerves or tomentum, these leaves could be 

 referred to the genus Cercocarpus H. B. K. /
