In its essential characters, FruUania Meyeniana is almost inter- 

 mediate between F. DonnelUi of Floi'ida, and F. Kunzei of the 

 southern United States, the West Indies and Brazil, two species 

 which are themselves very closely allied. The best points of dis- 

 tinction are found in the perichaHial bracts and bracteoles: in F. 

 DonnelUi^ the lobes and lobules of the bracts and the divisions of 

 the bracteoles (at least of the innermost row) are strongly incised- 

 dentate; in F. Meyeniana, the lobes are subentire, but the lobules 

 and the divisions of the bracteoles are coarsely dentate; while in F. 

 Kunzei, the divisions of both bracts and bracteoles are entire or 

 nearly so. In a sterile condition F. 3Ieyeniana differs from both 

 the American species in its more closely imbricated leaves and nar- 

 rower lobules, which are closer to the stem and to each other.

Autoicous: plants at first closely appressed to substratum, after- 

 wards forming- wide and intricate, depressed inats, yellowish-green 

 varying to reddish : stems at first rather regularly bipinnate, some of 

 the branches (especially the ultimate ones) microphyllous and of 

 short limited growth : leaves densely imbricated, the lobe orbicular- 

 ovate, arching over the stem but not cordate at base, slightly de- 

 curved at the rounded or obtuse, sometimes minutely apiculate apex; 

 lobule clavate, distant from the axis, widely spreading or subpar- 

 allel, rounded at the base, inflated throughout; stylus about a third 

 as long as the lobule, obliquelj^ triangular from a broad base, with 

 its apex close to the lobule : underleaves imbricated, orbicular, bifid 

 about one third, with broad, spreading or connivent, obtuse, acute, 

 or apiculate lobes and wide sinus, cuneate and not at all cordate 

 at base, entire or sinuately toothed on the sides : leaf -cells with 

 conspicuous, often confluent trigones and occasional intermediate 

 thickenings : 9 inflorescence borne on a principal branch ; bracts in 

 about three pairs, the lobe ovate to obovate (on innermost bract), 

 apiculate at the apex, entire or sparingly and coarsely toothed 

 in the upper part, lobule narrowlj'- ovate or lanceolate, acute and 

 apiculate, bearing a distinct lobe-like tooth or st^'lus near or below 

 the middle of the inner edge and sometimes a few minute and 

 irregular teeth nearer the base, otherwise entire ; bracteoles free
