 Fig. 4. 



The leaf figured here is better preserved tlian that figured in the Cret. 

 Fl. (loc. cit.). It is broader, seemingly somewhat decurrent to the median 

 nerve, and therefore like those of ilf. CapeUinii. This last species has, how- 

 ever, still larger leaves and has the lateral nerves not separated by interme- 

 diate, shorter tertiaries. The difi"erences between these two leaA-es and that of 

 M. pseudoariiD/'niafa Lesq. are not very well defined, and some of llu^ leaves 

 appear referal)le to either of the three species. 



Habitat: Pipe Creek, Cloud County, Kansas. No. 410L) of the col- 

 lection of Mr. K. D. Lacoe. 



Magnolia Lacoeana, sp. nov. 

 PI. LX, Fig. 1. 



Leaf large, broadly oval or nearly round, entire, obtuse or abrupth 

 pointed at the apex, narrowed and subdecurring to the base. Median ner\-e 

 somewhat thick, flexuous; secondaries alternate, parallel, declining to the 

 midrili in joining it, curved and camptodrome, ascending very high along 

 the l)orders with few branches in the upper part. 



The leaf difi'ers from the other fossil leaves referred to this genus by 

 its nearlv round form, its narrowing base and its numerous secondaries. 

 The petiole is liroken; the leaf is 10"'" long and S. .''/''" broad at the middle, 

 with ten pairs of secondaries at aii angle of divergence of 60°. By its 

 size, and more especially by the base of the leaves, it has a degree of like- 

 ness to M. Inr/lcjicldi Heer,' l)ut difi'ers greatly in the nervation. 



Habitat: Ellsworth County, Kansas. No, 215 of the collection of Mr. 

 R. D. Lacoe.

 (b'ome.
