lobule or beyond, compressed at the mouth and inflated in upper and 

 outer pai'ts; stylus minute, subulate : underleaves contiguous or 

 subimbricated, small for the subgenus, orbicular, plane or somewhat 

 revolute on sides, scarcely or not at all auriculate at base, bifid about 

 one third with subacute lobes and sinus, margins entire or sinuate-

 unequally bifid, the lobe ovate (or narrowly ovate on the innermost 

 bracts), obtuse to subacute, entire or sinuate on the margins, lobule 

 ovate or ovate-lanceolate, acute or acuminate, subentire but bearing 

 a distinct lobe-like tooth or stylus on the inner edge near the base ;

 about one third with narrow, acute or acuminate lobes and narrow 

 sinus, subentire or unidentate on sides; perianth about half exserted, 

 obovate, gradually narrowed into a short, broad beak, strongly 

 two-keeled postically and with a broad shallow furrow antically:

Fridlania Aongstroemii^ in most of the specimens at my disposal, 

 grows in company with what 'I have called F. Saudvicensis; and it 

 is quite evident that Angstrom's original Fndlania Sandvicensis, 

 as described by its author, is a mixture of these two species. His 

 sterile type-material, kindly sent me by Professor Nathorst, agrees 

 closely with his description (so far as leaves and underleaves are 

 concerned), and it agrees also with the numerous specimens of the 

 emended F. Sandvicensis, which I have been able to examine. In 

 his description of the perianth, however, he states: — "perianthium 

 obovatura dorso subconcavum canaliculatum saepe Iseviter bicari- 

 natuni, ventre bicarinatum," showing clearly that he did not have 

 the perianth of a Trachycolea before him, but that of a Ghonanthelia. 

 The lower bracteoles, moreover, are described as bipartite, which 

 certainly does not apply to the bracteoles of F. Sandvicensis, 

 although it is not quite accurate for those of F. Aongstroeniii. The
