424 GEOLOGICAL SURVEY OF THE TERRITORIES. 



Sassafras Mudgii, Lsqx., Amer. Jour. Science and Arts, July, 1868, 



]). m. 



The descrii)tion is right. This species is found at Saliua only. I have 

 not seen it represented by specimens from Fort Harker. 



Sassafras mirabilis, sp. nov. 



Leaves large, coriaceous, three-lobed, lobes diverging nearly in right 

 angles to the medial nerve, proportionally short, obtuse ; nervation very 

 thick. 



Beside the large size and broader lobes of the leaves, the species dif- 

 fers by the lobes of the leaves being more or less deeply cut or undulate- 

 dentate, with obtuse teeth. I have an entire leaf of this species,measur- 

 iug23 cent, broad, 16 cent, long, without the petiole, which is 6 to 7 cent, 

 in length. Though the nervation is of the same type as in S. eretaceus, 

 the primary veins are twice as large, the lateral curving outside and 

 diverging from the medial one. It has somewhat the appearance of 

 leaves of Platanus. It is apparently an incomplete specimen of this 

 kind which has been named and described as Flatanus latiloha by Dr. 

 Newberry. — Fort Harker. 



Sassafras obtusus, Lx. 



Leaves small, obtusely and equally three-lobed to below the middle ; 

 cuneate-narrowed to the long petiole ; lobes oblong, very obtuse ; nerva- 

 tion trifid from above the base. 



The leaves of this species are proportionally small, of a thinner sub- 

 stance, with secondary veins, narrow, straight, ascending to the border of 

 the lobes, and secondary veins thin, mostly camptodrome, parallel. In 

 one specimen the lateral lobes are cut in one short, obtusely-pointed 

 lobe, entered by one of the secondary veins; but in all the other speci- 

 mens the secondary veins are mostly camptodrome, simple, and the lobes 

 entire. In report 1871, p. 303, I consideied this species as the same as 

 the leaf which I had named Populites SaUsbiiriafolia in Amer. Journ. 

 Science and Arts, July, 1868, p. 94. It, however, differs by the more 

 marked and diverging entire obtuse lobes, and by the secondary camp- 

 todrome nervation. In this new species of Sassafras the lateral second- 

 ary veins are pinnately marked on both sides of the veins. In Populites 

 SaUsbur ice folia the lateral veins divide on the outside ouly. — Salina 

 Valley. 



Sassafras recurvatus, sp. nov. 



Leaves of medium size, thick, coriaceous, enlarged upward, divided to 

 below the middle in three lanceolate-pointed, long lobes, the external 

 ones scythe-shaped outside, three-nerved from the point of the petiole. 



Somewhat like the small forms of >S'. mirabilis, differing evidently, 

 however, by narrower, longer, obtusely-pointed lobes, by the ])rimary 

 nervation from the top of the petiole, and by the lateral veins dividing 

 near the base in two nearly equal strong branches, one ascending to the 

 jjointof the lobes, the other following the border and anastomosing in a 

 curve with the upper secondary veins. Sometimes this onter division 

 of the lateral veins seems to curve backwards and enter another inferior 

 lobe. But this appeareme is remarked only upon one specimen broken 

 at the sides, and whose form can merely be surmised from the dire('tion 

 of the veins. — Fort Uarker.
