DESCRIPTION OF SPECIES. 123 



the basilar submarginal. It is an enlarged form of var. 3, with very fine, 

 large leaves. 



No. 2701 of the U. S. National Museum collection, from near Fort 

 Harker, Kansas. 



Viburnum Lesquereuxii var. latius, n. var. 

 PI. LII, Fig. 10. 



Leaves enlarged, both sides obtuse at apex; coarsely dentate; lower 

 secondaries open with a pair of tliin basilar veinlets underneath. 



It is apparently a small leaf of the same variety, only differing by the 

 absence of marginal nerves. 



Viburnum Lesquereuxii var. lanceolatum, n. var. 

 ri. LIII, Fig. 3. 



Leaves round, cuneiform at base, of small size, lanceolate pointed, 

 lower secondaries, of which there are two pairs, nearly at right angles, 

 simple, marginal; the borders distinctly dentate. 



No. 2701J of the U. S. National Museum collection. 



Viburnum ? Lesquereuxii var. tenuifolium, u. var. 

 PI. LXIV, Fig. 13. 



Uncertainly referred to Vibui-num. From the other forms of F. Les- 

 quereuxii the leaf differs by its thin texture, its oblong-ovate shape, the thin, 

 less deeply marked nervation and the nearly entire borders, the teetli beino- 

 very small, like those of Betitlifes Wcstii, var. suhintegrifoVuis Lesq. In gen- 

 eral characters it is remarkably similar to the figure of Coryhpsis imdtiflofa, 

 given by Saporta in the text to his Flora of Sezanne (p. 394). It differs by 

 its broad diameter, the more open seccnidaries, and the direction of the 

 small border teeth. I ratlier think the leaf referable to the Hamamelidese. 



Habitat: Ellswortli County, Kansas. No. 1186 of the collection of 

 Mr. R. D. Lacoe. 



Viburnum sphenophyllum, sp. nov.' 

 PI. LIII, Fig. 4. 



Leaves long and narrowed, broadly cuneiform at base, tapering to 

 the pointed apex; distinctly, equally dentate on the borders; longer and 



'This species was named "Viburnum ouneatum, n. sp.," by Prof. Lesquereiix, but this name is pre- 

 occupied by the I'iburnum cHHfadim of Newberry (Foss. PI. from WestN. A., Proc. U. S. Nat. Mug. vol. .'> 

 p. 511). It was therefore necessary to change the name, and I have called it I'ihufimm auheiio- 

 phyUum.—F. H. K.
