DESCRIPTION OF SrEOlES. 143 



V'lg. 5, wliicli is a, t'oi-ni of the same, is c<>inj)aral)lc to (■raffff/iis (i/avii/a lieer,' 

 of the I'atoot Flora, wliicli merely ditfers by the obtuse teeth. I lia\'eseeii 

 ill the herbarium some young shoots of C .spafhulata Michx., with their 

 stipules, joined by their sides when dried and compressed; these stipules 

 looked like a round aj)pendag'e, superposed u[)on the base by oblanceolate 

 lea\'es, passing' above them and })resenting', if not the same form (the leaves, 

 being oblanceolate), at least an aj)})earauce of about the same character as 

 this leaf 



Habitat: Near Fort Harker, Kansas. No. 2i'>W of the U. S. National 

 Museum. 



Orat^gus Lacoki, sp. uov. 

 PI. LXIV, Fig. 14. 



Leaves small, oval, apparently obtusely i)ointed, cuneate from lielow 

 the middle to the base, with borders irregularly dentate above it; median 

 iier^'e strong, secondaries at an acute angle of divergence, thick, parallel, 

 mostly simple, craspedodrome. 



There are two leaves of al)Out the same size and form, 4.;")""' long, 3"'" 

 broad at the middle, and of strong, rigid texture, but not coriaceous, with 

 eight pairs of thick, straight, or rigid secondaries, which are mostly simple, 

 reaching the borders and entering the irregular teeth, A\'liich are long pointed 

 or short, slightly prominent, and diverging from the midrib at an angle of 

 25°. By their form, size, and character of nervation they are greatly like 

 some of the leaves of ('. tomentosa, being irregularly cut on the borders, 

 with close, simple, parallel, and equidistant secondaries. 



Habitat: Ellsworth County, Kansas. No. 572 of the collection of Mr. 

 R. D. Lacoe, for whom the species is named. 



Crataegus aceroides< sp. nov. 

 PI. LIV, Fig. 8; PI. LV, Fij;. 1. 



Leaves of medium size, coriaceous, ovate, simply or piimatclv lol)ed; 

 lobes entire; midrib narrow; secondaries mostly o|)[)osite, the lower pair 

 slightly supra-basilar; open, curved l)ack; those above jiarallel, more or less 

 ramose, craspedodrome, thcii- Ijranchcs camptodrome. 



There are onlv three fragmentarv leaves of this species whose affinity 

 with the ]ir('cediiig species is evident. Thev are somewhat like leaves of 

 Acer, but their nervation is peculiar, the lower secondaries being parallel,
