nblechnumA genus of hardy polypodiaceous ferns. The fronds are nearly or quite uniform and mostly pinnatifld or pinnate; the sterile veinlets are free, those of the fertile pinnæ being connected near their base by a transverse continuous receptacle which bears a linear sorus parallel to the midvein and provided with an elongate superior indusium free and at length reflexed from the inner margin. The species in cultivation are rather coarse greenhouse ferns which are very useful to florists for jardinières and for specimen ferns. The following are most commonly cultivated: B. Brasiliense, B. nitidum, and B. Corcovadense, of Brazil; B. occidentale, found in Mexico, the West Indies, and Brazil; and B. serrulatum, found in the regions between Florida and Brazil. B. cartilagineum, B. Lanceola, and others are also under cultivation.
