DESCKIPTION OF SPECIES. 175 



have a short, thick petiole 1"'" hmy, euhir^^^ed at the poiut of attacliiueiit. 

 The secondaries, of which there are tour or fivt^ pairs, are paralh'l, eqiii- 

 d'stant, and curve regidarly from their point of attaclimcnt to thc^ niichih 

 an<l foUow the borders, either simple or branching; the nervilles and the 

 areolation are obsolete. 



In form the leaves are comparable to those of ('dastnis miiiutulns Al. 

 Br., as figured in Heer's Fl. Tert. Helv. vol. 3, PI. cxxi. Fig. 42, but they 

 are nuicli larger; the nervation is that of G. Bnickmanm Al. Br., in Heer 

 (loc. cit.), PI. CXXI, Fig. 27. The form and size of the leaf are about the 

 same as those of Myrsine aittiqua Ung. (Syll., pt. 3, PI. vii. Fig. 7). 



Habitat: Kansas. 



El.«;odendron speciosum, sp. nov. 

 PL XXXVI, Figs. 2, 3. 



Leaves coriaceous, rigid, linear-oblong, attenuated at the base, obtusely 

 dentate or regularly undulate repand on the borders, entire toward the 

 base; primary nerve thick; secondaries inequidistant, oblitpiely diverging 

 from the median nerve, forking at or above the middle and again nearer to 

 the borders, flexuous, craspedodrome, with their divisions sometimes linked 

 at their ends. 



There are three fragments of these leaves with the same characters. 

 The leaves are thick, the surface rugulose by a small ([uadrate or puncti- 

 form areolation; the secondaries strongly marked, diverging at an angle of 

 30° to 35° from the median nerve, flexuous, diversely l)ranching near the bor- 

 ders, their divisions curving in an upward or downward direction and join- 

 ing the borders, \\hich are either inflated or bordered by a marginal nerve. 



The areas between the nerves are traversed lengthwise Ijy very thin 

 nervilles anastomosing at various angles, composing first irregular large 

 meshes tilled by very small quadrate or })unctiforni areoles. 



The nearest relation of the species is E. sagoriamim Ett.,' a Tertiary 

 species with the teeth of the border acute, the nervation more open, the 

 secondaries closer, equidistant, of a different character. The species from 

 Kansas has also in its nervation a, degree of aftinity to E. amirnh Vent,, 

 figured by self-impressions in Ettingshausen's Neuholl. Cliar. lOocenfl. Eur.,
