DESCEIPTION OP SPECIES. 137 



Eugenia prim^va, sp. uov. 

 PL LI II, Figs, 5-9. 



Leaves small, coriaceous, I'lHptical-lancoolate, obtuse, gradually nar- 

 rowed to short narrow petiole; nii(Ml) narrow; secondaries ver\' ol)li(|Ue, 

 thin, the lower pair opposite, a short distance above the base, ascending 

 nearly parallel to the borders; those above alternate, more curved in })ass- 

 iiig toward the borders, simple, camptodrorae. 



The leaves are referalile to this genus by all their characters and are 

 comparable to those of /'.'. harhifi'tana Ung. (Fl. von Sotzka, p. 52, PI. xxxv. 

 Fig. 19). The}" vary from 4.5""" to 8'^'" in length, including a sliort petiole 

 6""" to 8""" long; the divergence of the secondaries is 20° to 30" from the 

 midrib. 



The leaf shown in Fig. 9 is larger, luis a broader flat midrib, and the 

 secondaries are more open. It may be a different species, though I pro- 

 visionally named it var. raHda. It is more closely related to JtJ. Jiciriin/iai/n 

 Ung. as figured by Heer in Fl. Tert. Helv., vol. 3, PI. cliv, Fig. 13. " 



Habitat: Probably all near Fort Harker, Kansas. Figs. G, 7, 8, are 

 all numbered 2693 in the U. S. National Museum. 



Tribe LEPTOSPERME^E. 



BUCALYPTUS DAKOTENSIS, Sp. UOV. 



PI. XXXVII, Figs. 14-19. 



Leaves coriaceous, linear, or gradually narrowed from an obtuse apex 

 to the base, decurring into a short, alate petiole; borders recurved, median 

 nerve strong-; secondaries thin, obJi<pie, proximate, parallel, camptodrome. 



The species is rej)resented by numeroiis fragments of very tliick leaves, 

 about 1'° broad and at least 8"'" long; tlie l)orders are sometimes strongly 

 I'ecurved as in Fig. 1.'); sometimes flat as in Fig. 19, and jndging from 

 the fragment (Fig. 14) the leaves are obtuse at apex. The median nerve 

 is thick, especially so on the lower .surface, as in Fig. 19, where tlie flat- 

 tened borders are seen decurring along the median nerve at base and 

 thus bordering the shoi't, margined petiole. The secondaries, which are 

 gmui ^Q ^mm (jistjint at the base, traverse tlie blade at an angle of divergence 

 of 30° to 40°, and, cur\nng close to the borders, form by their crossing 

 simple, incumbent bows, like a marginal nerve, distinctly seen onlv on the 

 lower side of the leaves or of the fragments. 



The species is intimateh' related to E. Gcinitzi Heer, described l)elow,
