(Greek, lance-fern). Polypodiaceae. Small pot ferns with oddly pretty leaves.

Palmata

J. Smith. Leaves 4-9 in. each way, with 5 or more triangular lobes or the fertile still more divided; ribs black. W. Indies to Brazil. - Sometimes considered to be a variety of D. pedata, Fee.

nobilis, J. Smith. Larger: leaves sometimes 1 ft. long, pedately bipinnatifid; ribs chestnut. S. Brazil.

D. decipiens, with leaves resembling a geranium If., 3-6 in. each way, is sometimes cultivated, as is D. dtcora, with more divided leaves Both are natives of the Hawaiian Isls.

Dossinia

(E. P. Dossin, Belgian botanist. 1777-1852). Orchidaceae. One species of terrestrial orchids, allied to Anoectochilus, but lacking the bearded fringe on the lower part of the labellum. This species may possibly be cult, by a few amateurs who are skilled in the cult, of dwarf warmhouse foliage plants.

D. marmorata, C. Morr. (Ancectochilus Lowei, Hort.). Leaves golden-veined or marbled, 4-5 in. long, elliptic: scape pubescent, 10 in. high; spike 5 in. long, with many white, pubescent flowers Java. F.S. 4:370. - There is a stronger-growing variety, with foliage better colored.

Dracontium

(derived from the Greek word for dragon). Araceae. Greenhouse or hothouse plants, grown more for curiosity than for beauty.

Cult, as for Amorphophallus.

Asperum

Koch (Amorphophallus nivosus, Lem.). Petioles up to 9 ft. long and over 1 in. thick, roughened toward base with small warts conjoined in series, marked with large livid green and brown spots; blades up to 3 ft. broad, 3-parted, the divisions bipinnate, the ultimate segments oblong to lanceolate: peduncles 4 in. or more long; spathe up to 10 in. long; spadix 1 1/2-2 in. long.
