straight, but at the upper part they form a rounded shoulder where they join on to 

 the sharp angle of the leaf scar. They are prominently keeled, and the ligule pit is 

 placed in a line with the keel immediately below the leaf scar, for on the younger 

 branches and those of the size of this specimen the leaf base is directed upwards.* 

 There is no evidence to show that in older age they become derlexed in this 

 species, as in other members of the genus. 



The general form of the exposed portion of the fully developed leaf base is therefore 

 roughly hexagonal, but on very young branches it is more rhomboidal in form. In 

 Lepidophloios laricinus Sternb.t the exposed portion of the leaf bases is much more 

 truly rhomboidal and frequently transversely elongated with pointed lateral angles.

Description. — Seed varying in size from 1'50 to 2 cm. ; almost circular in form, 

 but slightly narrowed towards apex ; nucule cordate acute, lenticular, occupying about 

 half the area of the seed ; wing broad, slightly narrower at the base than at the 

 apex, where it has a distinct notch or sinus. 



Remarks. — This species is easily distinguished from Samaropsis Guibieri Geinitz 

 by its broad wing.
