540 Evans: HEPATICAE OF PUERTO Rico 
Puerto Rico, without definite locality, Schwanecke. The original 
determination of these specimens by Hampe and Gottsche has been 
confirmed by Stephani and also by Schiffner. The species has also 
been recorded from Brazil, the type locality, Se//ow, Spruce ; from 
Surinam, Reichenbach, Kegel; and from St. Vincent, Eliott. Ste- 
phani also mentions specimens from Ecuador without giving the 
collector's name. 
S. granulatum is known to the writer mainly from South Ameri- 
can specimens, and these are too incomplete to give an adequate 
idea of the species. Its relationship to S. transversale is very close, 
but Stephani considers the two species distinct. In pointing out 
_ the differences between them he notes that the lobule in S. granu- 
‘atum is smaller and also that the underleaves are smaller, more 
rotund in outline, cuneate and long-decurrent at the base and re- 
flexed on the margin. The underleaves in S. fransversale are said 
to be reniform, rounded at the base and plane. From the notes 
on S. ¢ransversale already given in the present paper it will be seen 
that some of these differential characters are not altogether reliable, 
on account of the great variability of the species. It should be 
stated, however, that the underleaves of SS. granulatum seem to be 
constantly cuneate at the base, and that their decurrence is not 
only more constant but more pronounced than in S. ¢ransversale. 
Whether the differential characters which Stephani derives from 
the perianth are trustworthy is also open to some doubt. In S. 
Sranulatum the wings of the perianth are said to be coarsely den- 
tate, while those of S. transversale are described as long- fimbriate. 
According to Spruce, however, the wings in Z. taeniopsis, which 
Stephani Teduces without question to S. granulatum, are incised- 
ciliate, some of the cilia being very long. Apparently some of 
these questions cannot be settled until more complete material is 
available for study,
