 these plants and the affinities of their characters will be satisfactorily dis- 

 cussed.

Cret. Fl., p. 112, PI. xxviii, Figs. 4-7. 



Order MYRICACE^. 



Myrica aspeea, sp. nov. 

 PI. II, Fig 11. 



Leaves coriaceous, linear-lanceolate, slightly falcate; narrow, cuneiform 

 and entire at base, crenulate-dentate above ; median nerve thick ; second- 

 aries strong, curved in traversing the blade, simple or forking at the apex ; 

 surface rough. 



Two specimens represent the species. The best preserved aud largest 

 leaf figured is 8.5"'" long, and 2'-'"' broad. The nervation appears mixed, 

 camptodrome aud craspedodi'ome. 



The species is related to M. fhidensis Heer\ two small fragments of 

 leaves with separate seeds doubtfully referred to the species and comparable 

 also to M. cretacea Heer from Quedlinburg. Its more marked affinity to 

 living plants is with M. cerifera L., allied as it is to it by form of leaves and 

 nervation. 



Habitat: Pipe Creek, Cloud County, Kansas. No. 4094a of the col- 

 lection of Mr. R. D. Lacoe. 



Mybioa Schimpeei, sp. nov. 

 Pi. II, Fig. 12. 



Leaves coriaceous, entire, linear-oblong, obtuse, gradually narrowed 

 to a short petiole and slightly decurrent at base ; median nerve strong, 

 percurrent ; secondaries thin, camptodrome. 



The leaf, 8™ long with its petiole less than l"™ long, is 17"" broad 

 above the middle and has a surface quite smooth and with the thin second- 

 aries curved upward, of varying length, all opposite, diverging 35° to 40° 

 from the median nerve. It has the same kind of nervation as M. emurf/inafa, 

 described below, and might be referred to this species but for the obtuse
