 smaller s])ecimen in tliis figure, from Sol/.l\a, 

 Styria, and Ettingshans<'n's specimens from 

 Monte Fromiinv in Dahnatia, figured on his 

 Plate VIII, show how closely this sonniwhat 

 later i'au'opean form a|)|)roaclies its American 

 prototype. Unger referred tliis sjx'cies to 

 M\'rica in 1850, altliougli 1k' recogni/.tnl its 

 proteaceous resemhlanees. Ettingshausen was 

 the leading exponent of the prt)teace()us afllnity 

 of this and nunu'rous other Tej'tiarv types. 

 Controversj' was at one time quite heated, and 

 among others Bentham in England w<>nt so far 

 tis to doubt the ability of anyone to recognize 

 a fossil leaf of the Proteacew. I think anyone 

 who takes the trouble to look into the subject 

 will lind it tliflicult not to see proteaceous 

 affinities in these forms, and ojiinion of late 

 years has been practically mianimous lliat tliis 

 modern antipodean tyjie was a cosmo])olitan 

 Tertiary type. This logical conclusion Inis 

 been fortified by the discovery of abundant 

 and characteristic fruits of several of the genera. 



Banksia tenuifolia is extremely abundant at 

 Puryear, Tenn., and occurs also near the head 

 of the embayment both in northeastern 

 Arkansas and western Kentucky. 



Occurrence. — Wilcox group, 4 miles south- 

 west of Bo3^dsviUo, Clay County, Ark (col- 

 lected by E. W. Berry). Lagrange formation 

 (in beds of Wilco.x age), Puryear, Henry 

 County, Tetui. (collected by E. W. Berry), and 

 Wicklifi'e, Ballard County, Ky. (collected by 

 R. H. Loughbridgc and L. V. Glenn).

Description. — Leaves of difT(u-ent sizes, lanceo- 

 late to oblong-lanc(M)late and most of tlnMu 

 falcate in general outlines, widest at or below

This species presents soim^ of the features 

 of Myrica, to which genus it may Ix-long. It 

 seems, however, to be more closely alliinl to tlie 

 two species of Banksia that avv. so al)un(laiit 

 in tin' Wilcox. It is much less elongatinl and 

 relatively wider than either Banl-.'iia triiuifolia 

 Berry or Btniksia saffordi (Lesqiiereux) Berry, 

 differing widely from the greatly elongated, 

 narrowly linear, toothetl lea\'es of ifnulfolia , 

 and with niucli finer teeth, shorter petiole, and 

 thinner texture than sutjordi. It is not unlike 

 cei'tain European Tertiary and modern Aus- 

 tralian species of Banksia. 



Occurrence. — Lagrange formation (in l)eds of 

 Wilcox age), Puryear, Henry County, Tenn. 

 (collected by E. W. Berry).

Descnption. — Emit :i large capsule, oblong- 

 elli])tical in lateral view, as shown in tin- iigiu-e, 

 ])resnmably nearly circular in transverse section, 

 the surface marked with obscure longitudinal 

 ridges, of which tlu'ee are indistinctly shown

 i-ounded distad, somewhat narrowed proximad, 

 where it is broken away from the pcnluncle.
