Doodia (Named after Samuel Doody)

(named after Samuel Doody, a London apothecary and botanist). ORD. Filices. A small genus of greenhouse Ferns. Fronds pinnate or pinnatifid. Involucres membranous, the same shape as the sorus. Sori oblong or slightly curved, superficial, placed in one or more rows, parallel with, and between, the midribs and margins of the pinnae. For culture, see Ferns. D. aspera (rough).* sti. 2in. to 4in. long, erect, asperous. fronds 6in. to 18in. long, 2in. to 4in. broad, oblong-lanceolate, with numerous spreading 1inear pinnae on each side, which are 1in. to 2in. long, 1/4in. broad; margin strongly serrated, base dilated. sori oblong, in one or two rows. Temperate Australia, 1808. D. a. corymbifera is a very pretty form, having the apex of the fronds densely crested.

D. blechnoides (Blechnum-like). sti. 3in. to 4in. long, erect. fronds 1 1/4ft. long, 6in. broad, oblong-lanceolate, with numerous spreading 1inear pinnae on each side, which are about 3in. long and 1/4in. broad, with sharply serrated margins and dilated bases. New South Wales, 1835. In the true type of this species, the upper pinnae are connected, the lower ones shorter and free, not dwind1ing down to auricles, which, Mr. Baker notes, is the case with the plant grown under this name.

D. caudata (tailed). sti. 4in. to 6in. long, slender, smooth. fronds 6in. to 12in. long, 1 1/2in. to 2in. broad, lanceolate, with numerous spreading 1inear pinnae on each side, which are about 1in. long; frond often terminated by a long entire point. Australia, &c., 1820.

D. c. confluens (confluent). fronds long, narrow, 1inear, upper part undivided, sinuato-pinnatifid in the lower part, with short rounded lobes. New Caledonia. SYN. D. 1inearis.

D. dives (Dives). sti. 6in. to 12in. long, slender, erect, smooth, scaly towards the base. sterile fronds 1ft. long, 3in. to 5in. broad, oblong-lanceolate, with numerous spreading oblong-1inear pinnae on each side, which are 2in. to 3in. long, 1/2in. broad; margin undulated and serrated. fertile fronds longer, with narrow 1inear pinnae. sori 1inear-oblong. Ceylon. D. 1inearis (1inear). A synonym of D. caudata confiuens. D. lunulata (crescent-shaped). A synonym of D. media. D. media (middle).* sti. 4in. to 6in. long, erect, smooth. fronds 1ft. to 1 1/2ft. long, 1 1/2in. to 4in. broad, lanceolate, with numerous spreading 1inear pinnae on each side, which are 1in. to 2in. long, and about 1/2in. broad; margin toothed, the upper ones dilated and connected at the base, those below the middle free and cordate, the lower ones gradually diminishing. sori short, oblong, distant. SYN. D. lunulata. There are several varieties, among which the following may be named:

D. m. duriuscula (rather hard). fronds firm, caudate; central pinnae about 1/2in. long, oblong, obtuse. sori one-serial, six to ten jugate. New Caledonia.

D. m. Kunthiana (Kunth's). fronds moderately firm; central pinnae close, bluntish, sharply toothed. sori one-serial. Sandwich Islands.
