DESCRIPTION OF SPECIES. 121 



in some fossil species, such as V. Strangei Mass^, whose leaves are also 

 coriaceous, strongly nerved but of diverse form; also in F. ritgosum Pers. 

 (pUoceniciim) Saj). & Mar.^ 



The long, thick petiole of these Cretaceous leaves does not contradict 

 their reference to Viburnum, for V. lantanoides Mx. has leaves with a very 

 thick petiole, sometimes as long as 4*"°, and V. nudum L., which shows the 

 same type of nervation and has leaves with petioles 2"™ to 2.5""' lono-; and 

 these, winged as they are, would appear, if they were seen compressed in 

 the fossil state, still thicker than those figured here. 



Habitat: Ellsworth County, Kansas. Nos. 12, 58, and 59 of the museum 

 of the University of Kansas; A. Wellington, collector. 



Viburnum ellswoethianum, sp. uov. 

 PI. XXI, Fig. 6. 



A single incomplete leaf, i-esembling in form, size, and texture the speci- 

 men (Fig. 4) of the preceding species. It differs from it by a stronger ner- 

 vation, the secondaries at unequal distance, simply camptodrome, curving 

 quite near the borders, less ramose, the uervilles close, nearly at right 

 angles along the median nerve. 



Though far different in appearance, the leaf may be a variety of V. 

 robust urn.

VlBUENUM Lesqueeeuxii,' sp. nov. 



Very variable in a diversity of characters which it is almost impossible 

 to characterize or consider as specific. 



Leaves round or broadly ovate, ol^tuse, pointed or longer, lanceolate 

 above, round, cordate, subtruncate or slightly narrowed and cuneate at the 



'Massalongo-Scarabelli, Fl. Foss. Senigall., p. 280, Pis. x, xi, Fig. 4.

^Thia iu Prof. Lesijuereiix's manu8cript is called "Viburnum dakotense, sp. nov.," but that name is 

 preoccnpied by the plant more appropriately so named by himself from the Bad Lands of Dakota in 

 his Cretaceous and Tertiary Flora, p. 231, PI. XLVi A, Fig. 9. While it seems a pity to disturb the 

 name given by himself to so important a species, it is, under the circumstances, a necessity. It should 

 not, however, bo regarded as an unmixed evil, since it affords an opportunity to add one more honor 

 to a name which is appended to very few species, considering the great number created by him who 

 bore it.— L. F. W.
