A. W. Evans — N'orth Amerieati Sjyecies of FruUania. 11 



D. C. (Coville): Austin, Texas (Underwood). On cypress pickets ; 

 St. Martinsville, Louisiana (Langlois). Distributed as FruUania 

 Virginica in Hep. Amer. 7i. 68. 



The determination of the plants which I have called FruUania 

 inflata is based on a small scrap so named from Austin's herbarium. 

 This material was collected in Mississippi by E. Hall, and no nearer 

 indication of its station is given. The species is apparently not rare 

 in the western Gulf States and it is probably commoner elsewhere 

 than collections would seem to indicate. At first sight the perianth 

 of F. inflata resembles that of F. Virginica., especially when young, 

 in having distinct supplementary ridges, but these ridges are never 

 tuberculate as in that species and are usually quite smooth. It also 

 differs from F. Virginica in its autoicous inflorescence, in its leaf- 

 lobes, which are scarcely if at all cordate at the base, and in its 

 areolation, the cells of the lobes having more uniformly thickened 

 walls. There is little danger of confusing it with any other southern 

 Trachycolea. Our New England F. Oakesiana is a much smaller 

 plant than F. inflata and its large lobule and different perianth will 

 readily serve to distinguish it. 



5. FruUania Catalinse n. sp. 



Plate IV. 

 Autoicous : plants growing in depressed tufts, reddish-brown, 

 sometimes tinged with greenish : stems irregularly pinnate : leaves 

 imbricated, the lobe ovate, squarrose when moist, arching over the 

 stem but not cordate at base, slightly decurved at the rounded or 

 obtuse apex, entire ; lobule broadly galealte, inflated, often imper- 

 fectly developed as a water-sac or wholly explanate, separated from 

 the stem by about one-fourth its width ; stylus subulate, usually 

 minute: underleaves distant, broadly rhombic, bifid to about the 

 middle with obtuse or subacute lobes and sinus, entire or more 

 commonly unidentate on the sides : leaf-cells with slightly thickened 

 walls, inconspicuous trigones and no intermediate thickenings : $ in- 

 florescence terminal on the stem or a main branch ; bracts in two 

 or three pairs, unequally bifid, the lobe ovate, rounded or obtuse at 

 the apex, entire or vaguely crenulate at base ; lobule shorter and 

 narrower, ovate, rounded to subacute at the apex, bearing a distinct 

 tooth or segment (stylus) at or above the middle of the inner edge, 

 otherwise entire ; bracteole connate on one side with bract, narrowly 

 ovate, bifid one-third or more with lanceolate lobes and narrow sinus, 

 otherwise entire ; perianth about half-exserted, somewhat compressed 

 at least in the upper part, fusiform to pyriform, gradually narrowed
