Sandwich Islands. Communicated bj Dr. H. N. Bolander, (1865). 



Differs from S. Jiaa, Nees, in the leaves being much less deeply fissured 

 at the apex.

A large species, being about the size of P.- sernireprdndu, Herb. Lehni., but 

 the leaves|are less strongly toothed, and the perianth more nuaierously angled, 

 the angles winged, &c. 



Phragmicoma subsquarrosa, Aust. 



Ph. caule brevi flexuoso compacte ca?spitoso rigido apice suberecto ; foliis 

 arctissime imbricatis in siccis subsquarrosis undulatisque obovato-rotundis 

 maxime areolatis, lobulo raajusculo semirotundo-ovato vix inflato ; amjihigas- 

 triis caule duplo vel triplo latioribus reniformibus apice subrecurvis ; perian- 

 thio obovato hand compresso circa 10-alato caUeroquin l*vi.

Perianth terminal, at length lateral, deeply and closely grooved or angled, 

 crowned with a very minute cylindrical tube. Calyptra crowned with a very 

 long style. Elaters very large, containing a single thick, imperfect fibre. 

 Leaves margined by a row of diminished, subequal cellules.

Near Augusta, Georgia, Sulliv., (1845). 



About the size and color of Frullania Virginica. Remarkable for the genuine 

 papilhe on the surface of the leaves and amphigastria,for the broadly inflexed 

 ventral margin of the leaf, and chiefly for the double row of amphigastria. 

 These are alternate with, and equal the leaves in number. They are f as long as 

 the leaves and less than i^ as wide, and are placed diagonally or obliquely 

 opposite them, and about midway between their upper and lower margin. 

 Areolation and texture of the leaves much as in Frullania Virginica. The 

 rootlets are remarkably stout, and of a brown color, and few in number ; and 

 proceed from the whole utider surface of the stem as well as from the base of 

 the amphigastria. A few stems on\y of the plant, without fruit, were found in 

 Mr. SuUivant's collection, mixed with L. serpgllifolia and //. Sullivantice. Dili- 

 gent but unsuccessful search was made for more of it, among numeroua speci- 

 mens from the same locality. 



Frullania saxtcola, Aust. MSS., (1865.) 



F. digyna: caule brevissimo arete repente vage innovanteque pluries ramose; 

 foliis orbiculatis (vix obliquis) planis vel subconvexis aut nonnuUo leniter 

 concavis subassurgentibus, auriculis cauli approximatis rarissime majusculis 

 subrotundis galeiformibusque autera fere semper parvis explanatisque ; am- 

 phigastriis minutis caule non vel parce latioribus subobovatis bifidis integer- 

 rimis, sinu lobisque plerumque obtusis ; perianthio compressiusculo oblongo 

 majusculo, ore brevissimo pateriformi papuloso, dorso convexo, ventre abrupte-
