in (liniiu'tcr. hluiuly puintod. ami not tu])t'riiii; 

 to any appri'ciahlc cxti-nt. A few of tlicsc 

 lateral branches fork psoiulodichotomously. 

 and some of them jrive off toward thi>ir distal 

 ends tiny lateral hranchlets less than 1 centi- 

 meter in len<;;th and about 1 millimeter in 

 diameter. 



The general proportions are thus decidedly 

 diflerent from those of the supposed parent 

 t_vpe. The leaves are slifjhtly smaller and 

 smoother and relatively somewhat more elon- 

 gated, at the same time laekinjj the apical 

 papilla and the convergent striae. The form 

 is much more graceful in api)earance than the 

 type and in its general aspect suggests the 

 Lower Cretaceous genus Arihrofaxopsis of 

 Fontaine. 



\Mule tiny species of Brachyphyllum like 

 Brachiipiiyllum microcladnm Saporta, of the 

 Xeo-Jurassic, have been described, the new 

 variet}- is even more slender than Brachy- 

 phyllum yracUf Brongniart. of the Jurassic. 

 The most closely allied form known appears 

 to be one from tiie .Vlbian of Buarcos, in Por- 

 tugal, described by Saporta '" as Brachy- 

 phylbim ohesiforme elongatinn. The present 

 form also shows considerable resemblance 

 to BrachyphyUuni crassicaiilc Fontaine, of the 

 Patapsco formation in Maryland and Virginia. 

 This variety is abundant throughout the 

 Tuscaloosa formation and in the basal part 

 of the Eutaw formation in Alabama and west- 

 ern Georgia and occurs also in the Woodbine 

 sand of Texas but is kno\vn in Maryland only 

 from a single locality. It is also confincid to a 

 single locality in North Carolina, where it is 

 not at all uncommon but is not especially well 

 preserved.

Ileer's (lescri[)tion, published in 1SS2, is as 

 follows: 



M. foliis olilongis, intogerrimi», apioe i>umn;inuii.-i, l)ii.»i 

 attonuatiH, norvis sei-umlariis sulUilissiiniH. 



Tliis species, which was described from speci- 

 mens collected in the Atane beds of (Ireenland, 

 has been recorded from the Karitan ami Tusca- 

 loosa formations of the Atlantic Coastal Plain 

 and from the Dakota sandstone of the Western 

 Interior. It is somewhat variable in form 

 but may be characterized as follows: 



Leaves obovate, widest at the rounded, 

 truncate, and more or less eraarginate ape.\, 

 with entire margins narrowing to the cuneate 

 base. Midril> mediiimly stout. Secondaries, 

 five thin pairs, subo[)posite, diverging from 

 the midrib at angles of about 4.5°, campto- 

 drome. 



The reference of this species to the genus 

 Myrica is entirely problematic. It is astonish- 

 ingly close to a form from Niederschoena, 

 Saxony, described by Engelhardt '" as Minm- 

 sopx ballotaevides.
