DESCRIPTION OF SPECIES— CBLASTRE^. 269 



ondary nerves rurviii<if at a distance from the borders, and fi)riniii'r a doulih; 

 S(M-ics of" hows by anastomosis of the nervilles. Tiie characters of the nerva- 

 tion are (he same as in Celastrus cassinrfoUus, Ung., figured by Ileer (Fl. 

 Tert. Helv., iii, pi. c.wi, tigs. 24-2G), but our leaf is twice as hirge as those 

 represented by tlie jMiropean authors. I liave l)eeM a long time in doubt, 

 and am still uncertain, of the true rclalion of this.and the Ibllowing species. 

 Habitat. — Golden, Coh)ra(h) {Iter. A. Lnkcs).

Loaves bard, subcoriaceous, with a smooth or polislieil Huifaco, apparently lon<;, linear or olilonn,. 

 with horders distantly (lenticnlato; secondary nerven in ri^ht angle, braucliin;; from the middle, each 

 with one or two intermediate!, parallel, tertiary vein-*. 



Nothing has been seen in relation to this species but the fragnniiifs 

 figured, which represent the lower part of somewhat large k-aves. They 

 greatly resemble part of leaves ot" Banksia and Dnjandroidcs, mostly now 

 considered as Myrica, like D. BanksmfoUa, Ung., D. /fevigata, Sap., I), ligni- 

 tum, etc., as may be seen by the numerous figures representing these species 

 in Ilcer (Fi. Tert. Helv., ii, pi. xeix, figs. 4-16). The character of nervation 

 presents a notable difference; for, in this American form, the secondary veins 

 do not pass on to near the borders but anastomose in the middle of the lamina 

 l)y nervilles joining them to ijranchlets, either of the tertiary or of the upper 

 secondary lusrves, and, l)y their subdivisions, they form along the borders a 

 double or triple range of festoons. This character indicates their relation 

 to Ihc CelastrecB, and is marked indeed in some of the species of Celastrin'Ues 

 described by Saporta in the Sezanne Mora, especially in C. legitimus and C. 

 ■i;e«?//osM.v, as represented in pi. xv, figs. II, 12, and 13. I followed tlie opinion 

 of this celebrated paleontologist in referring these fragments, like the former, 

 to lliis genus. 



Hauitat. — Six miles above Spring Canon, top of the hills, l>etween 

 Fort Ellis and Bottler's Ranch, Montana {Dr. F. V. llayikn).
