Asparagus plumosus, Baker. Asparagus Fern. Fig. 404. Woody, tall climbing vine: roots not tuberous, long, slightly fleshy: st. terete, green-glabrous: branches with twigs and cladodes arranged in a horizontal plane, making a compound pinnate frond, triangular in outline: cladodes numerous, 8-20 in a fascicle, ¼ in. or less long, slender, terete, bright green: lf.-scale white or gray, on main st. developed below into a woody deltoid spine: fls. 1-4 at ends of twigs, white; perianth-lobes spreading obovate, blooming in autumn: berry 1-3- seeded, purple-black. S. Afr. F. 1882:101. F.R. 4:93. F.S. 2413-14. G. 25:110. G.C. II. 13:749; III. 23:146. G.Z. 25:2. A.F. 11:1178.—A popular decorative plant now almost superseded by some of its varieties. The cut sprays and strings of A. plumosus and its varieties are used in large quantities by florists on account of their beauty and keeping qualities. Most of the forms are prop. by seed or division but some are readily increased by means of cuttings. Var. comorensis, Hort. (A. comorensis, Hort.). Similar to A. plumosus but more robust: cladodes lighter green, more open and delicate in their arrangement: frond widely triangular, very regular. A.F. 18:684. F.E. 14: 462. F.R. 9:877. G.C. III. 23:181. Gng. 10:295. I.H. 42:61. S.H. 1:84. V. 20:101. Var. nanus, Hort. Fig. 405. The common commercial variety of the species: cladodes more numerous and shorter than type, making the horizontally spreading fronds more dense: sts. Often short, making a short spray rather than a vine: easily reproduced by seed, which germinate in three weeks. Var. tenuissimus, Hort. (A. tenuissimus, Hort.). Fig. 406. A wiry stemmed variety with fewer cladodes longer than in type and not so much in a horizontal plane, distinctly glaucous blue-green; not a strong climber. Var. robustus, Hort. A ranker-growing vine with shorter cladodes than type, side branches making longer and more irregular fronds than A. plumosus nanus, a duller green. A. plumosus superbus, Hort., A. Blampiedii, Hort., and A. Hatcheri, Hort. (F.E. 31:935), are all botanically closely related if not identical with A. plumosus robustus and with it are separated from the other forms of the species by their stronger growth and by the much less regular arrangement of the cladodes and twigs into a horizontal plane. Var. compactus, Hort. A dwarf form, said to be a hybrid between A. plumosus nanus and A. plumosus tenuissimus, suitable for pot-plants. F.E. 16:637 See Fern, Asparagus.
